The invention relates to adhesive compositions and method of fastening products on the substrate or on the canvas.

Specific application of this method and this adhesive composition is mounting items on walls of buildings and similar bases. In particular, sanitary and kitchen area wall provided with a lining consisting of tiles, ceramic tiles, stone or marble tiles. In General terms, the method applies to a variety of applications, such as aircraft construction, shipbuilding, construction of steel structures.

For mounting on the walls of the items of equipment, such as furniture, lighting, sanitary ware type of towel holders, can be known by use of the fastening means in the form of screws. However, to do this, first in the walls must be made of the drilling, and drilling entered the dowels. In order to avoid damage to the high walls, such as tile, these drilling is usually performed in the joints between tiles, which is an undesirable way restricts the location of the fastening means. Another disadvantage is that if after some time you need to change the installation location of the equipment, at the old place of installation remain prominent drilling. This means the flax deteriorates the appearance of the wall even in the case when these drilling filled with filler.

To eliminate these disadvantages, attempts were made to replace the mounting means in the form of screws adhesive means.

In the simplest case, this can be an adhesive tape, in the simplest case of double-sided adhesive tape. Its drawback is, on the one hand, that such fastening means behind over time. Another disadvantage is that they are not suitable for attaching to the walls of any heavy items.

In principle, for fastening goods on such basis as the walls of rooms or buildings, you can use the aerobic adhesive. However, the problem here stems from the fact that such aerobic adhesives must be cured within a few hours, while for curing requires a supply of moisture. If you put a layer of aerobic adhesive to the product, then the product with a layer of adhesive to be pressed against the base located between the product and the Foundation layer of adhesive becomes isolated from the ambient air, which makes it impossible for the aerobic curing adhesives.

The mounting system that enables the use of such aerobic adhesives known from the patent document WO 03/036106.

This mounting system is used for stationary mouth of ovci of such products, as towel holders, shelves, lighting fixtures and other items of equipment on the wall, ceiling, or similar surface, especially in areas with walls tiles, marble tiles and other mounting system consists of fasteners of various types and adhesive or connecting means, which may be formed of aerobic adhesive. The fastening elements are made of ceramics, and can be adapted in shape in accordance with the purpose. The disadvantage of such systems is a very long time curing, which can take up to twelve hours, which significantly reduces the ease of installation.

The fastening element is for receiving the holder of the product and contains the main body, which is turned towards the back wall has a recess and leading him to the pouring hole. Through this hole adhesive or coupling agent is introduced between the fixing element and the wall.

To release air that is displaced adhesive or connecting means at its input into the recess, the fastening element is provided with at least one transmissive liquid and the gas channel, which extends from the recess to the other outer surface of the fastening element and takes the excess adhesive or connecting means.

Turned to a wall of the rear side is and the main body is made permeable to liquid and gas, at least their partial areas. Thus, when the curing is located in the recessed adhesive or connecting means can extend the generated gas or evaporate volatile binder. Simultaneously to this adhesive or connecting means may be ambient air, so that it can harden and to ensure sustainable and able to withstand the fastening of the fastening element on the wall.

The disadvantage of this solution is that the execution of the main body is connected with considerable additional design costs and it also does not allow free placement of the fastening means.

Database WPI Week 198916 Thompson Scientific, London, GB; AN 1989-119544 XP002535598 & JP 01 066279 A (TOYO KOGYO CO.) March 13, 1989 (1989-03-13) described adhesive composition for attaching objects on the ground, consisting of aerobic adhesive, which consists of polyurethane and hydrophilic material in the form of salt. In document EP 2202276 disclosed structure Milanovich MS polymers.

Object of the invention is to create a stable, flexible adhesive compositions for mutual attachment of two objects that do not require constructive interference in these objects.

In accordance with the invention the solution of this problem is achieved by signs, set out in paragraphs 1 and 4 of the claims. Preferred options for implementation and appropriate decisions on development of the invention set forth in dependent clauses.

The adhesive composition according to the invention consists of a mixture of aerobic adhesive and hydrophilic material and is designed as a mounting kit, which contains two containers for separate storage of aerobic adhesive and hydrophilic material, which may be selected from the container for mixing the adhesive composition.

The basic idea of the invention is that by adding to the aerobic adhesive substance hydrophilic receive material forming the adhesive composition of the mixture, which now does not require surface contact with moist ambient air to cure in the direction from the outer surface. Instead of existing in a mixture of hydrophilic material which permeates the aerobic adhesive, provides the possibility of curing this is contained in a mixture of aerobic adhesive from the inside outwards in the absence of external contact containing moisture with the surrounding air. Required for curing the moisture and oxygen contained in the hydrophilic material, since the latter due to their hydrophilic properties contain enough moisture is for aerobic curing adhesive in the mixture, forming an adhesive composition.

Due to the fact that hydrophilic materials, depending on environmental conditions or give the moisture in the environment, or absorb it from the environment, depending on the application, the moisture content in the hydrophilic material may be insufficient, so that after mixing with the aerobic adhesive to ensure full curing of the mixture.

However, the amount of moisture in the hydrophilic material or a mixture of hydrophilic material with the aerobic adhesive substance is of great importance. Excess moisture prevents bonding, too low humidity causes no reaction in polymers formed by the aerobic adhesive substance, so that curing does not occur.

To obtain adequate moisture in the adhesive compositions according to the invention a mixture of aerobic adhesive and hydrophilic material is carried out dosing moisture. It is particularly advantageous to produce dosed additive moisture hydrophilic material before it is mixed with an adhesive substance.

Especially suitable for metered additive fluid wooden paddle, which is used for mixing and pre-immersed in water or, in a broad aspect, some amount of liquid. The amount of water or, in a broad aspect, the amount of fluid that mo is et to perceive blade, forms a metered quantity of liquid, which is served in a mixture of aerobic adhesive and hydrophilic material. This hydrophilic material can act as a humidity buffer that can absorb excess moisture and put her needs. Due to the mixing process, the moisture permeates the entire volume of the mixture so that the mixture can harden completely. Alternative blade can also be used in other dispensers for supplying moisture. In principle you can use liquid-containing capsules. They burst in the mixing process and give moisture to the mixture. Due supplements capsules, as due to the hydrophilic additive material can be improved durability of the adhesive compositions according to the invention, tensile strength and shear. In principle hydrophilic material as the battery humidity can be added accumulating granular material.

Due to the mixing with hydrophilic materials curing occurs significantly faster than all other methods.

When using the adhesive composition according to the invention can easily attach objects to each other by the fact that the layer of adhesive composition is applied between two objects.

When this layer of adhesive compositions may be entered in any dredging or deepening of objects and information objects possess is about being completely in the closed inner space, that is, in the space bounded by impermeable to diffusion surfaces and isolated from the ambient air. However, if this is the reliable aerobic curing adhesives and the corresponding connection object, capable of withstanding high loads. In addition, the adhesive composition may be applied on a flat surface. There is also an adhesive composition according to the invention can be incorporated between two impermeable to diffusion surfaces for their mutual attachment.

In a particularly advantageous embodiment of the invention aerobic adhesive formed wilanowie MS-polymers.

In principle hydrophilic materials can be formed salts. Particularly preferred hydrophilic materials formed of hydrophilic fiber-carrier, which may be a natural or chemical fiber and preferably consists of cotton. In principle, as hydrophilic materials suitable chalk, flour, clay, galactose, wool, flax, hemp, viscose, cellulose, algae, felt, and wood fiber, filter materials with air and then generally breathable materials.

Significant advantages of the adhesive compositions according to the invention is that to perform the function of the adhesive composition does not require fine the enforcement ratio in the mixture of adhesive and hydrophilic material. To ensure the best possible good aerobic curing adhesives is advantageous only to the hydrophilic material was uniformly mixed with the aerobic adhesive.

Next to the use of the adhesive composition is essential to the components of the adhesive compositions were mixed shortly before its application.

For this purpose, in the preferred embodiment, the prepared mounting kit, which contains two containers for separate storage of aerobic adhesive and hydrophilic material, in particular hydrophilic fiber carrier. Of these containers, components can be selected as desired for mixing the adhesive composition.

Because you don't have the exact ratio of aerobic adhesive and hydrophilic material, the adhesive composition of these components can be quickly and simply involved even inexperienced personnel.

The following advantages of the adhesive compositions according to the invention is that with its help can be obtained detachable connection of two objects. This feature is based on the fact that created by the adhesive composition, the compound has a very high resistance to traction forces, but less resistant to impact efforts shear or cut. Therefore, by turning the object is created by gluing to what notizia the connection can be broken. After that the attachment can be cleaned from the remnants of the adhesive composition with a shovel or similar tool.

According to the method according to the invention the object is fixed on the base by using the following steps.

First knead adhesive composition by mixing a hydrophilic material, in particular hydrophilic fiber-carrier, with the aerobic adhesive. Then put a layer of the adhesive composition on the object and then fix the object on the basis of by pressing the layer of adhesive composition to the base. In this layer the aerobic adhesive cures with moisture contained in the hydrophilic material.

In a particularly preferred embodiment, before mixing with the aerobic adhesive hydrophilic material dosed way give humidity.

Particularly preferably, when the base may be formed by a wall, and the object formed by the fastening element, which may be a product of the equipment.

Thus the product of the equipment mounted on the fastening element after cured layer of the adhesive composition between the wall and the fastening element. In General, items of equipment can be installed on the wall directly together with the fastening element.

According to the invention the fastening of the adhesive composition on the wall is made without ISOE is isawanya screws and similar items, so the wall does not do any drilling.

Thus, the fastening is carried out without damage or harm to the walls.

This is particularly advantageous in the case when the wall is provided with a wall cladding tiles, ceramic tiles, stone or marble tiles, which secures the fastening element.

For sensitive and typically expensive wall cladding is the process of attaching is no risk of damage or harm to the walls.
