The present invention relates to textile materials for technical purposes, in particular to products for the manufacture of construction building blocks of concrete with a facing of tiles.

Known technical solution of duplicate material household products containing fabric mesh made of nylon fabric or knitted fabric and a porous foam layers which are thermally bonded together (Handbook of merchandise (Non-food) in 3 volumes. Vol. 1. Thegrove, Uphrates, See etc. - 3rd ed., Rev.): Economics, 1988) (the closest equivalent).

The disadvantage of this technical solution is that you cannot use duplicate material in the manufacture of building blocks due to the low absorptive capacity of the cement milk, bonding strength layer and its thickness.

When this blocks out low quality as it dried, unabsorbed duplicated material cement wash with stubborn pieces porous layer remain on the visible surfaces of the blocks. The visible front portion of the block additionally has a non-uniform arrangement of the tiles.

Before the invention of the goal of the project is to eliminate the mentioned disadvantages and to create a solution to improve the quality of building blocks.

P the set objective is achieved by that duplicated material for the manufacture of building blocks with a facing of tiles containing paintings of cellular and porous layers which are thermally bonded, the resistance to delamination is from 0.01 to 0.19 kN/m, the porous layer has a surface density ranging from 40 to 168 g/cm2and consists of smooth anticiption filiform elements, the porous material has an apparent density of from 10 to 50 kg/m3and duplicate material has a thickness of from 1.0 to 3.0 mm

This object is achieved by the fact that the duplicated material is its ability to cement suspension is from 403 to 1075 g/m2.

The task is achieved by the fact that the filiform elements mesh layer is made of a smooth and anticiption.

This object is achieved additionally by the fact that as the material of the porous layer used polyurethane foam or other otkritosty porous polymer, such as polyethylene foam, foam rubber and other

This object is achieved by the fact that the duplicated material has an elongation of at least 20% in the longitudinal and transverse direction.

This object is achieved in that the duplicated material fabric mesh layer is made of knitted or woven weave.

This object is achieved in that the oak is new material, the porous layer has a color, appropriate design features lining.

Duplicated material according to the invention is made from selected components by way of gadoksetovaya, for example, on line Bonding (BONDING) or plum (PLAMA).

The use of the invention in terms of the production line blocks for house-building plant is as follows. At the bottom of the trough for forming block is placed in a grid with cells corresponding to the size and shape of the tiles lining the concrete block. It should be covered duplicated material of the porous layer to the grid. Then on the foam layer of the composite material lay out the tiles and press them into the cell. Next, the resulting structure is covered with filler and fill with cement mortar or immediately pour the concrete solution of the desired consistency. During the curing of the concrete on the surface of the tiles may receive the cement milk, which, after the completion of the technological process of manufacture can harden on the surface and spoil the appearance of the block. To avoid this applies duplicated material having a design that allows you to fully absorb the cement milk. After removing the grille duplicated material should be removed without residue from the tile area or joints. It should be noted that part d is morovannoho material will cleave to tiles and concrete. Therefore, we need to duplicate material that has good resistance to delamination and good absorbency at the same time. For this porous layer has a surface density 40-168 g/cm2, elongation not less than 20%, and resistance to delamination is not less than 0.01 kN/m, which gives the duplicated material necessary strength and elongation, as well as the penetration of excess cement film on the surface of the composite material. The thickness of the composite material is 1.0-3.0 mm, which allows you to absorb the desired amount of cement milk and at the same time to prevent the extrusion of the tiles from the cells before they sleep filler or concrete. The apparent density of the porous layer is from 10 to 50 kg/m3together with mesh layer provide the required absorptive capacity of the cement slurry 403-1075 g/m2, breaking load not less than 60 N in the longitudinal and transverse direction, has an elongation of at least 20% in the longitudinal and transverse direction.

Usually in such duplicated materials applied polyurethane foam, but it can be replaced with other Otkrytiye porous polymers, such as otkritosty foam or foam rubber.

Porous layer can be made of knitted or woven and nonwoven even weave.

In a separate CL is the teas duplicated material placed mesh layer on the grill. Then when you delete the duplicated material often incomplete removal of the porous layer of the building block. Therefore, the porous layer make a color in accordance with the design facing.
