The invention relates to a coating containing synthetic film that is formed on the basis of at least one polymer material, and placed in a matrix of polymeric material Supplement.

The invention relates further to a method of manufacturing a coating, wherein the polymer material is applied on the coated surface and polimerizuet by subsequent exposure to energy.

The invention relates further to a device with an installation for applying a polymeric material to cover the surface.

The manufacture of a composite material formed from the base material and deposited on the surface of the base material generic coatings known from the prior art. This achieves a separation of functions, and the coating performs liaison functions, and material-based - load-bearing function. The properties of this composite material can be varied for a given application due to the choice of materials, the shape, the rigidity and strength of the composite material are determined by the material, and the surface properties of a coating.

A common practice is to manufacture synthetic film-based polymer material, for example reacto or thermoplastic, and a matrix of polymeric material placed additional components that about who has the change in the surface properties. So, for example, from EP 0667931 B1 is known of the cylinder-piston unit, in which the inner surface of the cylinder is equipped with a synthetic layer containing at least one component to improve dry lubricating properties. Further, from this publication it is known that the quality of the plastic is covered on the inner surface of the cylinder causing the three-dimensional crosslinking dust or powder of thermosetting and at least a thermosetting then sew through heating. To dust or powder of thermosetting before applying to the coated inner surface of the cylinder add additional components as additives, and at least one component improves dry lubricating properties of the inner surface of the cylinder.

The disadvantage of composite materials, however, is the fact that possibilities of purposeful influence on defined synthetic film surface properties of the composite material is insufficient to meet the complex requirements of the composite material.

For example, in the process of automatic production of indispensable necessity is positioning parts in the manufacturing process and upon its completion, for example for Assembly purposes. There are also many cases when the identification part is basically the value. Such cases include checking the availability of parts or assemblies in inaccessible places, for example in the Assembly in the automotive industry, safety aspects, such as anti-theft protection, motion detection, etc.

For positioning of parts of the prior art it is known the use of reed elements placed below the surface of the parts. The prior art are, in addition, the measurement of electrical resistance that varies depending on the position of the parts, as well as incremental principle, and an electromagnetic sensor in the cylinder head contactless feels special patterns under the surface.

To identify the surfaces of the parts to be coated or have already undergone the coating process of the prior art known to the bar code, integrated circuit or tuned circuit, placed on identifiable details or identifiable surface details.

The use of reed elements, sensors, barcode and other electronic elements are connected, however, with the disadvantages. These elements have to arrange for an additional operation on the part or under the surface of the part to determine the position or for identification. Moreover, the reed elements provide only one-dimensional identify the bookmark position, which is a disadvantage.

In General, up to now in the prior art there are no suitable for economical, but nevertheless, precision and industrial production methods of performing the corresponding synthetic layers and optimization of synthetic layers with respect to the corresponding destination.

The basis of the present invention lies therefore, the task of improving the coating to the base material of the synthetic film so that the defined synthetic film surface properties could purposefully be set and adjusted properly applied, so that the composite material can be purposefully applied upon presentation of comprehensive requirements.

According to another aspect of the problem should be provided identifying parts, and the positioning of the parts without the use of additional structural elements with simple handling.

For technical decision task, it was proposed that synthetic film formed by several multi-layered zones, at least one of which includes changing the properties of the component.

Thanks composite material according to the invention, in accordance with the first solution proposed to perform deposited on the surface of the material is the basis of synthetic film of several multilayer zones and to create layers of different composition, adjustable in its properties independently from each other. Preferably proposed to separate the multilayer zones differ from each other in the relationship is enabled, changing the characteristics of the components and/or in respect of polymeric materials, making required in certain areas of the property upon presentation of a very complex requirements can purposefully choose and depending on the application handling.

Changing a property of a component in the sense of the present invention are called to be included in the polymer matrix, cross-linking or LESSIVAGE with her supplements that improve, modify, optimize, and other surface properties, such as impact on lubricant, water repellent, etc. properties.

According to another preferred variant of the invention, the concentration included in the multilayer zone components that modify the properties varies in the thickness direction of the layers. The calculation of the properties of the layers depending on the thickness of the layers is preferable in this case, in particular, when between two different layers or between the material base and the first layer should be created a smooth transition.

Particularly preferably below suggested that a separate multilayer zones are located one above the other and/or next to each other, repeating surface contour is the material base. By performing located one above the other and next to each other multilayer zones creating dependent load layer properties limited not only related to the function of the loading place, and can be adjusted depending on the depth of the impact load.

Thanks composite material according to the invention, the preferred way is provided to supply the base material solid synthetic film and the creation of synthetic film, in which different zones has a different composition and a different structure and, thus, can be selectively adjusted in relation required in certain areas of the property. Created by the surface properties can be, for example, sealing ability, resistance to scratching and impact strength, compatibility with lubricants, paints, hydraulic fluids, hydraulic properties, suitability for treatment, the hardness or recyclability. At the same time in different zones synthetic film can be different polymer matrix, in which are included the various, changing the properties of the components. Separate areas may have a single layer structure, and concentration on, changing the characteristics of the components varies in the thickness direction of the layer. Multi-layer structure of the synthetic is Lenka and purposeful influence on the properties of individual zones allow the preferred way to create a specific application profiles properties so there is a composite material that can be applied in many areas. Possible fields of application can be, for example, food and pharmaceutical industry, equipment for environmental protection, coupling and drive technology, shipping, gidroenergeticheskii systems, or chemical and automotive industry.

Next, thanks to the invention proposed that the Supplement contains magnetic particles, even if the film is formed of only a single layer of polymer matrix.

Thanks to the coating, according to the invention proposed, therefore, to include in the matrix forming synthetic polymer film material of the magnetized particles and to form within the coverage of the information zone. The magnetized particles are included in the matrix forming synthetic polymer film material, can be selectively magnetized after performing synthetic film using the appropriate electromagnetic recording and/or reading device. Synthetic film performs, so as to cover the base material is not only known from the prior art contact features, such as, for example, protection against chemical or corrosive influences, but also serves simultaneously as a carrier of information, and due to just what about the magnetization of the magnetized particles, included in the matrix forming synthetic polymer film material, using the appropriate electromagnetic recording device can be recorded any information. This information can then be independent from the place of magnetization second read and processed by the corresponding electromagnetic reader.

Preferred, the coating according to the invention is, therefore, constantly associated with the material-based storage media. Information, which is accumulated inside the formed synthetic film coating and, if necessary, can be read, are, for example, identification codes of the parts, as well as information for determining the position on the workpiece. The preferred way, you avoid additional structural elements necessary still to identify or determine the position. The coating according to the invention, for the first time creates the opportunity to use the markings on the surface of the base material synthetic film at the same time as the information carrier. While the preferred way of performing information zones within the coating requires no additional manufacturing or additional operations as included in the synthetic film Ref is by the particles in the manufacturing process of the coating are included as such.

In addition to identifying details or information for determining the position on the details of the magnetized areas of the coating can be used for long-term storage of information for the purpose of quality assurance. For example, the coating can be placed information, giving information about the place and time of manufacture or geometric dimensions. Still in the process of manufacturing these data can be read for quality control and compared with corresponding reference values. The preferred way information property coverage is not visible from the outside and does not affect the appearance, so placed in the coverage information may remain on the part after its production, which opens up the possibility of establishing compliance. It is preferable, in particular, in respect of warranty obligations.

In addition to these examples of possible still, and many others. It is crucial that the coating according to the invention, the first surface coating, which serves as a contact function for protection from external influences, and information functions.

According to one characteristic of the invention, the additive comprises a magnetized particles of chromium dioxide. The use of chromium dioxide was preferred because of the chromium dioxide has a first, optimal magnetizing properties, and secondly, is persistent in the magnetized state. In addition to the chromium dioxide can be applied to other magnetic materials such as iron oxide.

According to another characteristic of the invention, the additive includes the addition of magnetic particles further and modify the properties of the components. Preferably it is possible, therefore, to form a synthetic film, specifically designed in relation to the expected load.

According to another characteristic of the invention, plastic film consists of several layered zones differing from each other in respect of incorporated additives and/or polymeric material. This opens a preferred way, the ability to perform synthetic film of several multilayer zones differing from each other in respect to their composition and regulated independently of each other in their properties in relation to the expected load. Also, upon presentation of high complex requirements, thereby purposefully choose properties and adjust them depending on the application. Thus, it is possible to choose areas that do not contain magnetic particles contain only the magnetized particles or contain magnetic particles in combination with other com is hentai, so maybe selectively performed posando magnetization of the coating.

According to another characteristic of the invention, the concentration included in the matrix of polymeric material additives vary. This variation of concentration can occur, for example, in the thickness direction of the layers, and the calculation of the properties of the layers depending on the thickness of the layers is preferred, particularly when between two different zones, or between the material base and the first coverage area should be created a smooth transition.

According to another characteristic of the invention, a separate multi-layer zones are located one above the other and/or next to each other. Preferred as a result of such execution creating dependent load layer properties not limited solely attributed to the function of the loading place, and can be adjusted depending on the deep impact load.

Thanks to the coating, according to the invention, the preferred way allows the supply of the base material solid synthetic film on the basis of at least one polymer material and perform when this coating, in which different zones has a different composition and a different structure and, thus, can be purposefully adjusted as against required in certain areas of the property, t is to and selectively magnetized through the use of magnetic particles and used, thus, as the carrier of information. Created by the surface properties can be, for example, sealing ability, resistance to scratching and impact strength, compatibility with lubricants, paints, hydraulic fluids, hydraulic properties, suitability for treatment, the hardness or recyclability. At the same time in different zones synthetic film may contain various polymer materials with different polymer matrices, which in addition to the magnetized particles included various changes properties of the components. Of course, some areas may have a single layer structure, and the variation of concentration included components occurs both in the direction of thickness of the layer and perpendicular to it. Multi-layer structure of the synthetic films and purposeful influence on the properties of individual zones allow in combination with the possibility of collecting information to create a specific application profiles properties, so there is a coating in the form of synthetic films, which can be applied in many areas, and which at the same time as during the entire manufacturing process and after it provides identification provided coverage details. Possible applications the Oia can be for example, the food and pharmaceutical industry, equipment for environmental protection, coupling and drive technology, shipping, liquid-energy systems, chemical and automotive industry or safety, and protection of goods.

Generally, the invention proposed coatings that contain altering the properties of the components and/or magnetic components.

According to a particularly preferred aspect of the invention, the multilayer structure in certain areas due to the removal of the upper layers can exert its action components properties of the lower layers. This removal can occur, for example, by grinding, turning, or other suitable measures or damage the upper layers in separate zones can be closed by the bottom layer. Because of this aspect of the invention can be formed by a coating that has a surface purposefully varied or optimized properties.

According to another preferred variant of the invention, the coated surface has a structuring. For example, may be applied to a spiral structure for optimum effects, for example, in cooperation with the seal of the hydraulic system. Due to the spiral embossing surface or at the expense of comparable structureof the deposits is an easy way to optimize the o-ring lubrication. In the framework of the invention it is also possible other profiling for transporting liquids, targeted removal of liquid or other fluid, etc. we are Talking about the so-called maleinovyi.

In regard to the aforementioned method of manufacturing such a composite material as a technical solution to the problem suggested that the polymeric material is applied depending on mixed-altering properties of the components with the formation of multilayer zones.

To obtain a composite material according to the invention, for applying the polymer material is not required to process the surface of the cover of the base material. However, to create certain properties can be applied to any mechanical and/or chemical conversion methods. As suitable for coating materials-fundamentals covers all known metallic structural materials (e.g., iron base alloys, cobalt, copper, magnesium, titanium), as well as ceramics and natural materials. Can be covered with cast, forged, sintered or drawn and rolled semi-finished or finished products.

According to a particularly preferred variant of the invention, the polymeric material in a single operation is mixed with the transforming properties of the components and applied to the coated surface. So about what atom, during the same coating process can be obtained as zones of layers of different composition and locally different thickness layers. Also you purposefully set dependent load layer properties in relation to the function, and depending on the depth of the impact load. Alternatively, it can also be added to the polymeric material before applying to the coated surface modifying properties of the components. This alternative implementation method applied matrix and include the materials to be applied on the coated surface mixed together, and then following each other phases of the layers applied to the base material.

At the same time as matrix materials for the included components can be used any polymer materials (thermoplastics, thermosets, elastomers). By combining different is limernyh materials in one matrix material can be preferred to have an additional influence on the properties of multilayer zones synthetic film.

According to another preferred variant of the invention, as altering the properties of the components can be blended with a crosslinking or LESSIVAGE with them components. Possible that changes properties of components are, for example, metallic or non-metallic solids (for example, carbides, nitrides, oxides and Nearside), solid lubricants (e.g. graphite, coal, MoS2), pure metals (e.g. iron, Nickel, tin, copper and alloys, and corrosion inhibitors. All include substances can be used with different grain size.

The formation of synthetic films occurs by heating and deriving from that the cross-linking of polymer material deposited on the coated surface of the base material with the addition of at least one modifying component property. This crosslinking of the polymer material may be due to sufficient heating cover of the base material either before or after application of the polymer material. In any case, however, you should pay attention to when using magnesium as altering a property of the component, the heating temperature was below about 200C. According to another preferred variant of the invention, crosslinking of the polymer material can be further from obstsalat through the use of an electrostatic field or specific wavelength fractions of radiation.

According to another preferred variant of the invention, using the method according to the invention, forming a multilayered areas of different thickness layers. Therefore, the preferred way to form functional zones with different properties and, in relation to the thickness of the layers, to create a gradient material of the desired thickness.

According to another characteristic of the invention, the powder coating may be applied to rotary or coagulation by means of spraying, such as flame spraying of polymers or metals in the bath for turbulent deposition, and by electrostatic spraying. For electrostatic spraying of powder coatings are suitable, in particular, thermosets, powder varnish of epoxy, polyester and acrylic resins. When the vortex coating is applied, in contrast, thermoplastics from PA, PVC or polyester and polyepoxides. Alternatively, a coating in liquid form.

As described above, due to a combination of different polymer materials in one matrix material can be preferred to have an additional influence on the properties of multilayer zones synthetic films. It should be borne in mind that the magnetized particles as metallic solids are LESSIVAGE components and therefore is best suited for inclusion in thermosets. Depending on the installed namagnichivaemost you can use different granulometric composition.

By the way, according to the invention, the preferred way created the possibility of making coatings, and polymer coating has a structure with a locally once the diversified profile properties and contains bands, which to accumulate information included in the matrix of polymeric material of the magnetized particles.

Thanks to the invention of an entirely new way of coating. For one or each separate layer, you can set the desired thickness and, knowing the exact sprayed amount by management depending on route and time to manage the damage amount, so exactly what held on the details of the applied amount forms a precise thickness. Next, a method in which the thickness measurement is contactless, for example, with ultrasound. Because parts are not heated after the coating is not bound. For example, when applying the powder by an electrostatic charge to keep the amount of powder on the part. The thickness measurement can occur contactless, and even the control surface may occur optical and/or electronic means, for example by converting the image into digital form. As there is no cross-linking in the presence of a defect to heat the item and re-cover. This method provides optimal control and is extremely economical.

In addition, thanks to the invention it is proposed to remove the top layers, or by coating the bottom layer prevent the IC on the application of the top layer, so thus manifested its effect of different components of the properties of different layers in different areas. This removal can occur, for example, also to stitching or by grinding after stitching.

Next, thanks to the invention it is proposed to structure the surface, i.e. subjected to embossing or any other way to provide structure, the result of which can be formed channels, cavities, passages, etc. for example, it is possible to perforate the upper layer, in order to make available water-absorbing and conductive properties of the lower layer, however, the use of dry lubricating properties of the top layer. According to the method, the structuring can be carried out prior to stapling or before the final hardening during curing, so that, in General, occurs economical and preferred management method.

Synthetic film 2 is, in turn, of several multilayer zones located adjacent to each other, repeating the contour of the base material, and forming functional zones A, B, C, D. a Synthetic film 2 contains also included in the matrix of polymeric materials that change properties of components.

Separate multi-layer functional areas A-D synthetic film 2 differ from each other in terms included in a separate functional areas, changing the characteristics of the components and/or polymeric materials. So, for example, plastic film is in the functional area, And from a polymeric material with a matrix structure of M1. This polymeric material is included changing the properties of the components E1E2-Exat a concentration of, respectively, C1C2-Cx. Synthetic film 2 is a functional area In the same way as in the functional area, And on the basis of polymeric material with a matrix structure of M1however , unlike functional areas And contains only one change property component Eyat concentrationsy. The functional area With plastic film 2 is formed polymer m is a material with a matrix structure of M 2. Within this functional areas in a matrix of M2the polymer material is not included altering the properties of the components. Finally, functional area D synthetic film 2 is made as a functional area, based on the polymeric material with a matrix structure of M2. However, unlike functional zones within functional areas D-altering properties of the components of Exincluded in the matrix M2at concentrationsx, a Ezin concentration Fromz.

In the exemplary embodiment in figure 1 the state of the surface of the base material in the functional areas B-D obtained turning, and the functional area And additional grinding. In principle, however, a special surface treatment of the base material 1 before application of the synthetic film 2 is not required.

Figure 2 schematically and in detail shows the structure of the functional areas And from figure 1. As you can see, the functional area And are made of different multilayer sections I-X, which are located one above the other, repeating surface contour of the base material. As a separate functional zones A-D, these separate sections I-X differ from each other in terms included in these plots, changing the characteristics of the components and/or polymeric materials. In this example, execution of figure 2 Shin is Etiketka film 2 is performed on some sections I-X on the basis of the same polymer material with a matrix structure of M 1. However, in relation included in the matrix M1the polymer material changes properties of multilayer components parts I-X are different from each other. So, the first section I contains a component E1at a concentration of C1plot II - component of E2at a concentration of C2plot III - component of E3at concentrations3and the plot of the X - components of Exat concentrationsx.

Depicted in figure 1 and 2 as an example execution synthetic film 2 shows the preferred way combination of different polymer and include materials that are printed on the same material base with the formation of a solid synthetic film 2, which in different functional areas has a different composition and different structure.

On the figures of polymeric materials in accordance with their matrix structure is marked with the letter M, the additive - Z, and the concentration - C. So, for example, the coating is In the functional area And of the polymeric material with a matrix structure of M1that includes additives Z1, Z2at a concentration of, respectively, C1C2. When this additive Z1represents the magnetized particles. In the functional area, And the coating can therefore be magnetized using the corresponding magnetizing devices, so this coverage can be used simultaneously as a carrier of information. The coating is performed In the functional area, as in the functional area, And, based on the polymeric material with a matrix structure of M1however , unlike functional areas And contains only additive Z2at concentrations2and does not contain magnetic particles. This coverage area, therefore, is not magnetized. In the last functional area covering In synthetic film formed from a polymer material with a matrix structure of M2. Within this functional areas in a matrix of M2the polymer material does not include the additional substances.

In the example run on IG surface of the base material G in the functional areas of a and b obtained turning, and in the functional area, And additional polishing. In principle, however, a special surface treatment of the base material G before coating is not required.

Figure 4 schematically and in detail shows the structure of the functional areas And from figure 3. Here you can see that functional area And are made of different multilayer plots A1-A4, which are located one above the other, repeating surface contour of the base material. As a separate functional zones a-C in figure 1, the individual multi-layered plots a1-A4differ from each other in terms included in these plots additives and/or polymeric materials. In the exemplary embodiment of figure 2, the coating is performed in the functional area, And in some areas A1-A4on the basis of the same polymer material with a matrix structure of M1. But included in the matrix M1polymer additives individual multilayer plots a1-A4differ, however, from each other. So, the plot of A1contains an additive Z2at concentrations2plot And2- additive Z2in the same concentration as the site of A1and advanced additive Z1at a concentration of C1. Additive Z1represents the magnetized particles, and the additive Z2- is obaku, improve, for example, corrosion-proof properties of the coating Century Finally, the plot And3contains an additive Z1at a concentration of C1only the magnetized particles. In contrast to the overlying sections A1-A4located directly above the material-basis G plot And4contains no additives and is formed solely of polymeric material with a matrix structure of M1.
