The invention relates to the field of construction machinery, namely the production of decorative building materials for interior and exterior walls and other structural elements of buildings and structures.
From application EP 078404 AND is known for finishing decorative and protective material in the form of a plate comprising a base fabric made of fiberglass that is coated with a film of synthetic material provided with a layer of plaster, composed of granular or powdered insulating substance, there is also a cement binder, zaterannoe water containing a dispersion of a synthetic polymer material. This known material is designed for finishing of external walls and has high strength, but is very high stiffness, which limits the scope of its application and use.
From the patent DE 4239269 WITH known finishing decorative and protective material in the form of a laminated plate, which includes a base of foam, which has at least one flat side is covered cured with a solution of a synthetic material, in which the clamped fabric of fiberglass. This well-known finishing decorative and protective material also has high rigidity because of its high resistance to twisting and bending, Thu is also limits the scope of its application and use.
From the patent RU 2195522 C2-known finishing decorative and protective material with a basis of flexible non-woven fiberglass material, the front side of which is covered with a layer of utverzhdenii weight mineral powder filler, comprising a hydraulic binder, the latent hydraulic binder, a filler, a wetting agent, a silicate, dispersion, powder, thinner and stabilizator, retarder, thickening agent and defoamer. This known protective decorative material has good flexibility and can be used for finishing surfaces having a different form, however, has the disadvantage of low permeability that is associated with the use of it it is mineral fillers with molefractions composition in which fine particles are between large and delay pairs. In addition, the particle size of up to 0.1 mm does not provide a wide range of decorative this known material, since the granular structure of such particles are not visually distinguishable. Complicated and the manufacturing technology of such well-known finishing material, including many components and requires special equipment serviced by qualified personnel.
The invention is aimed at the creation of finishing what about the decorative and protective material, which resolves the above drawbacks of the known analogues, i.e. to create the finishing decorative and protective material having high strength, flexibility and breathability with a wide range of decorative and simple in composition and production.
This technical result is ensured by the fact that in the proposed finishing protective and decorative materials as the basis used non-woven geotextile, having a thickness of 2-6 mm, one side of which, like the front, covered by a layer of utverzhdenii mass that runs from a mixture of stone chips having a particle size of 0.15 to 2.5 mm, pre-treated with epoxy paint, and a polymeric binder, in a ratio of 4-1. When this epoxy paint for pre-treatment stone chips includes epoxy resin, hardener and pigment or mineral dye, as a polymeric binder used water-dispersion acrylic, or polyvinyl acetate, or epoxy materials, the thickness of the layer utverzhdenii mass on the basis of non-woven geotextile consisting of a mixture of stone chips, pre-treated with epoxy paint, and a polymeric binder, is 2-7 mm, and the front surface of this layer utverzhdenii mass covered with a layer of polymer swiatowej is, diluted with water in the ratio 1÷10. Preferably, the thickness of the layer of polymeric binder diluted with water in the ratio 1÷10, was 0.1÷1,0 mm
In the process of manufacturing, we offer finishing protective decorative material pre-mixed epoxy resin, hardener and pigment or mineral dye, thereby obtaining an epoxy paint of the selected color, which then, together with rock dust is stirred for 1÷5 hours at a temperature of 15÷30°, for a uniform distribution and subsequent curing of epoxy paint on the surfaces of the particles of crushed stones, which in this stirring remains in granular masses of the individual particles. The obtained granular mass of stone chips treated with epoxy paint, mixed with a polymeric binder, maintaining the ratio between them 4÷1, achieving a uniform distribution in the polymeric binder particles of crushed stones, and then the resulting mass of the polymer binder is a stone crumb distribute a uniform thickness layer on the front substrate surface of the nonwoven geotextile and subjected to curing by drying at a temperature of 90-100° for 3-5 hours. After cooling the obtained product obverse surface layer utverzhdenii mass (stone crumb-polymer relations the future) cover a uniform thickness layer of a polymeric binder, diluted with water in the ratio 1÷10, and the drying of this layer is carried out in a natural way without the use of any auxiliary tools, such as heating or by blowing. Preferably, the thickness of the layer of polymeric binder diluted with water in the ratio 1÷10, was 0.1÷1.0 mm, and the particle size of stone chips was selected from the range of 0.15÷2.5 mm
Using the proposed finishing decorative and protective material of non-woven geotextiles as a basis aimed primarily at ensuring its flexibility and weight reduction, i.e. the light that can significantly extend the scope of the proposed use of the material, i.e. to use it for finishing the construction of structural elements of any hardness and any surface that needs protection and decoration.
Thus the performance of the surface layer on the surface of nonwoven geotextiles in the form of a cured layer of the proposed stone-polymeric composition provides reception decoration decorative and protective material sufficiently small thickness and having a good flexibility, which enables to produce and to use it not only in the form of flat sheets, but also in the form of rolls, which is convenient for storage and transportation to the place of application (for example, to the building surface to the showing in need of protection and/or reconstruction), and for cutting blanks of the desired size and shape at the place of use. The tests showed that the proposed finishing decorative and protective material can be used when it is applied not only on a flat surface, but on a curved, for example with rounding sharp corners, or on an uneven surface with traces of old plaster, which is especially important for the restoration of old buildings.
Use as the basis of non-woven geotextile is also related to the fact that it is an environmentally friendly material and has a high resistance to chemical attack, resistance to thermal-oxidative aging, and also has high physical and mechanical properties, which fully shows the proposed finishing decorative and protective material. Experiments and tests have shown that the proposed finishing decorative and protective material can be used any known brand non-woven geotextile, such as non-woven geotextile brand NETEX AND (NETEX), see http://www.isolux.m/catalogue/geosintetiki/geotekstil/netkanyj_geotekstil_netex_a_netex/, or non-woven geotextile brand of IPR, or mark "Dornit", see http://pskgeodor.ru/node/7 and http:all-for-building.ru/44518-stekloholst_pautinka.
Specified in the claims, the range of thicknesses basics - nonwoven geotextile (2-6 mm) were obtained experimentally. To the to the experiments showed this range in combination with the specified particle size of stone chips (0.15 to 2.5 mm) optimally meets the requirements for flexibility finishing material suitable for application to surfaces of any shape, for example on the walls of buildings, flat, or curved, or other elements such as portals, columns, pedestals, roof, etc. At the same time, as the experiments showed, the combination of thickness of non-woven geotextile and particle size of the particles of crushed stones and provide high levels of durability and breathability receive finishing material, its durability, i.e. the indicators of its protective properties.
It should also be noted that the choice as the basis of cladding material of non-woven geotextile related to its good adhesion with the polymer mass, i.e. in respect of the invention is cured on the surface of the nonwoven geotextile mixture of stone chips, pre-treated with epoxy paint, and a polymeric binder.
Stone chips can be obtained by crushing and/or grinding pieces of natural stones (granite, marble, vermiculite, etc. and sifting them through a sieve with cells of a certain size to obtain particles of stone chips of a given size. The choice of particle sizes of stone chips allow the us to extend the offer decorative finishing material, providing some degree of roughness of its outer surface.
Pre-treatment stone chips epoxy resin, which includes a curing agent, to increase the adhesion with the polymeric binder and the basis of non-woven geotextile. In addition, the curing of epoxy paint on the surface of particles of crushed stones prevents waste and strengthens individual particles of stone chips having defects, such as cracks, as in the processing of stone chips epoxy paint water misses her microcracks, which contributes to the durability of the cladding material.
Inclusion in epoxy resin pigments or mineral dyes of different colors allows for unlimited decorative expand the range of facing materials.
For pre-treatment stone chips can be used any known epoxy resin, for example of the brand ED-20 (GOST 10587-84), which is a liquid reactive oligomeric product on the basis of diglycidylether ether of diphenylolpropane. Uncured Dianova epoxy resin ED-20 converted into infusible and insoluble state by the action of the curing agents (hardeners) different types of aliphatic and aromatic di - and polyamines, nizkomolekulyarnye the polyamides, di - and polycarboxylic acids and their anhydrides, phenol-formaldehyde resins and other compounds. As the experiments showed, the most appropriate use as a hardener polyethylenepolyamine (PEPA) (TU 6-002-593) as the most common and available industrial product. To extend the range of decorative design decorative and protective material used mineral dyes and pigments are metal oxides and inorganic salts, which are introduced in epoxy resin together with a curing agent, for example, may be used pigments known brand LANXESS Bayferrox or any other.
In addition, to regulate the structure of epoxy coating on the surface of particles of crushed stones can also be used modified (doped) silicon additives, such as tetraethoxysilane (TES), a synthetic heat-resistant silicone rubber (SCTN), octamethylcyclotetrasiloxane (ACTS), polymethylsiloxane (ICP-5000), enter in the amount of 0.5-1.5% wt. in relation to the weight of the actual epoxy resin with hardener and coloring.
As the polymer binder can be used water-dispersion acrylic, or polyvinyl acetate, or epoxy materials, such as VINNAPAS SAF54, or ACRONAL 290 D, or Novopol-110, cat is that when polymerization become transparent.
These polymeric binder in the proposed finishing decorative and protective material used as the adhesive medium, which are uniformly distributed is treated with epoxy particles of stone chips that together forms the layer to be solidified mass with a uniform coating on the surface of the base in the form of a nonwoven geotextile. The presence in the curable mass and the specified polymer binder and epoxy paint on the surfaces of the particles of crushed stones significantly improves its adhesion performance. So formed on the surface of non-woven geotextile layer such mass and of itself is very durable solid monolith, and when it is cured on the surface of the nonwoven geotextile is formed between them is as strong inextricably monolithic connection geotextile-curable mass, which has a certain degree of flexibility, which depends on the selected or specified combinations of thickness of non-woven geotextile, particle sizes of stone chips and the thickness of the layer of the hardenable mass.
Tests have shown that the proposed fabrication and finishing decorative and protective material allows to achieve not only a wide range of decorative and high consumer indicators of resistance to atmospheric impact of the m, including temperature changes over a long period of time, and wind loads that must be considered when the facades of buildings and structures. In addition, the combination of a specified range of particle sizes of stone chips, the thickness of the curable layer, specified polymer binder and nonwoven geotextile directly connected, as shown by experiments and tests, ensuring increased consumer indicators breathability offer a finishing material.
It should be noted that epoxy paint used for pre-treatment of stone chips, and a water-dispersible epoxy material that can be used as a polymeric binder, is a different matter. Epoxy paint used in the invention for processing stone chips, is organic composition comprising epoxy resin, hardener and pigment or mineral dye, and a water-dispersible epoxy material that can be used as a polymeric binder in the invention is a waterborne dispersion, such as the brand "EPOXY".
By varying the specified thickness of non-woven geotextile, which is 2-6 mm, and a particle size of stone chips, which is 0.15-2.5 mm, it is possible to extend the range of application of otdalin the first material, requiring a particular flexibility, durability, etc. depending on the situation when using, for example from an object to be finishing, or climatic conditions that dictate a certain degree of required protection of the object.
Manufacturer offer the finishing decorative and protective material is as follows.
Epoxy resin, hardener and pigment or mineral dye of a given color are placed in a mixer, for example, provided with a screw or other mixing body, and the exercise of their mixing until a homogeneous mass in the form of epoxy paint, which is then mixed with stone chips until evenly distribute the epoxy paint on the surfaces of the particles of stone chips and cured on the surfaces of the particles of crushed stones, leaving the stone chips in the form of a loose mass of individual particles. To do this, carry out their stirring for 1-5 hours at a temperature of 15-30°C. In the resulting granular mass of stone chips treated with epoxy paint, add polymer binder in the ratio of 4÷1 and performs the stirring until a homogeneous mass is designed to cure in the form of the adhesive layer on the substrate surface of the nonwoven geotextile.
To do this, the resulting mass is in the form of a mixture of stone chips, is designed epoxy paint, and a polymeric binder distribute a uniform thickness layer on the front substrate surface of the nonwoven geotextile and subjected to curing by drying at a temperature of 90-100° for 3-5 hours, after which the front surface utverzhdenii weight evenly covered with a layer, whose thickness can be 0.1÷1.0 mm, from any of the above-mentioned polymeric binder diluted with water in the ratio 1÷10, and left for drying at room temperature for 1.5÷2.5 hours, after which the finishing decorative and protective material is ready for use.
The front surface of the thus obtained decorative decorative and protective material has a decorative surface roughness due partly projecting particles of stone chips that can be painted in different monocot, or to have a mixed color of different colors. Applied on the front surface a uniform thickness coating of a polymeric binder, diluted with water, is primarily protective, reinforcing, i.e. strengthening and linking partially protruding particles of stone chips, and, in addition, it adds Shine, glossiness rough front surface finishing decorative and protective material, thus improving its decorative qualities
It is important that the thus obtained cured layer of a mixture of stone chips treated with epoxy paint, and the specified polymer binder has good flexibility, the degree of which depends on the selected combination of components used therein, i.e. from the set value of the particles of stone chips, the thickness of the cured layer on the surface of the nonwoven geotextile and its tosini.
Depending on the shape of the piece of cloth used nonwoven geotextiles can get the finishing decorative and protective material with defined structural effect of the plaster in the form of a strip, easy skachivaemoe in a roll, from which further cut into pieces of required size and shape, and in the form of flat sheets of any size and any shape, such as required by a particular situation of use. If this describes the manufacturing technology of the material is such that its shape and size depend only on the shape of the basics - a separate piece of non-woven geotextile.
The tests showed that the proposed material can be used for finishing the surfaces of various materials, i.e. concrete, metal, wood, etc. When this bond offer cladding material with the surfaces to be finish as dormancy is expressed experiments, can be carried out by mechanical means, for example by means of screw connections, anchor, etc. and other, for example adhesive. However, such funds are not subject to legal protection in the framework of this proposal and will be described in other applications.
Thus, the invention is characterized by a set of essential features, each of which is necessary, and together they are sufficient to create a finishing decorative and protective material that combines high strength, durability, flexibility and elasticity in bending, breathability, and is also capable of providing the wide range of its decoration.
The technology of production of the proposed cladding material is simple and does not require expensive equipment and highly qualified staff, the ingredients included in the proposed finishing protective decorative material available and inexpensive, which together ensures its mass production.

FIELD: construction, particularly removable non-load-bearing partitions and partitions with a free upper edges.
SUBSTANCE: partition member comprises two outer spaced apart sheetings and heat-insulation filler arranged in-between. Filler includes several layers parallel to outer sheetings. At least one inner heat-insulation layer is in contact with heat-insulation layer located next to outer sheeting and has improved elastic characteristics. Above heat-insulation layer has dimensions exceeding that of adjacent layer or layers so that after that heat-insulation layer arrangement between outer sheetings and adjacent insulation layer or layers counter force is created to permanently press adjacent heat-insulation layer or layers to outer sheeting or sheetings so that extreme heat-insulation layer is brought into oscillatory cooperation with above sheetings.
EFFECT: improved acoustic properties along with increased structural simplicity and reduced costs.
