However, when these adhesives are applied to decorative and finishing fabric, the decorative appearance is disturbed; when glued, the adhesive is transferred from fabric to substrate.

The closest in technical essence and the achieved result to the invention is adhesive for the face tapes on substrates made of acrylonitrile butadiene styrene-polyvinyl chloride compositions and other film mats GZ, containing, in%:

Copolymer of butyl acrylate with acrylonitrile containing 10-20 7.9-14 acrylonitrile,

Adhesive additive 10.7-16,

Silicone resin - the product of cohydrolysis of phenyltrichlorosilane with dimethyldichlorosilane 0.8-1.6

SolventExtra

Glue cannot be used for the manufacture of decorative polyamide fiber fabric, as it changes its decorative appearance and has low strength properties during multiple gluing (dismantling).

- The purpose of the invention is to ensure enhanced tackiness with repeated gluing and preservation of the decorative appearance of polyamide fiber finishing fabric with glue.

The goal is achieved by the fact that glue, including a copolymer of butyl acrylate with acrylonitrile with an acrylonitrile content of 10-20%,

5 complex ether plasticizer, silicon dioxide resin and solvent, contains, as silicone, a condensation product, methyl silantriol and phenyl0 silantriol taken in a ratio of 1: 2, and additional titanium dioxide in the following ratio, wt.%:

Copolymer of butyl acrylate with acrylonitrile containing 10-20% acrylonitrile 5-20

The condensation product of methylsilantriol and phenylsilantriol, taken in a ratio of 1: 2 3-16

Ester plasticizer0,5-2,2

Titanium dioxide f- 0.5-2.2 Solvent Else

The composition uses a copolymer of butyl acrylate with acrylonitrile with an acrylonitrile content of 10–20% (butyl acrylate rubber). Sebacic acid esters (dibutyl 5 sebacate or dioctyl sebacate) are preferably used as ester plasticizer.

The condensation product of methyl silant .riol and phenylsilantriol (silicone resin K-9) is obtained

60 from methylchlorosilane and phenylchlorosilane, taken in the ratio 1: 2, It is a solid product from light yellow to brown in color with a content of cream dioxide65 of 52-55%.

Acetone or a mixture of acetone with cyclohexane in the ratio 1: 2 can be used as a solvent.

Making glue.

A butyl acrylate rubber, a condensation product of methylsilantriol and phenylsilantriol, a paste consisting of a filler and a plasticizer, and a solvent are loaded into a glue mixer. Stirring is carried out for 5-7 hours until complete dissolution of the components and obtaining a homogeneous solution.

The finished adhesive is a white liquid with a viscosity of 26006200 cP using a Brookfield viscometer.

Testing of the glue is carried out after applying its smooth surface of decorative and finishing fabric of polyamide fiber, drying the adhesive layer at BS-70 s for 5-7 minutes.

Decorative and finishing fabric with a sticky layer is tested according to the following parameters.

Peeling resistance from AMG-6 plate at 20 + 2 ° С, V; 100 mm / min:

In delivery condition;

after the first sticking;

after the second glueing /

after the third glueing.

This indicator characterizes the repeated gluing, i.e. the ability to produce, if necessary, the dismantling of decorative and finishing fabric with a sticky layer.

Preservation of a decorative type of fabric. Evaluation of a decorative type of fabric with a sticky layer after exposure to UV rays at a temperature of 50 ° C for 30 minutes is made visually, as the decorative and finishing fabric is a translucent canvas of light tones, easily perceiving the hue of the glue and the surface on which it is glued.

In tab. 1 shows examples of proposed adhesives, as well as control formulations.

In tab. 2 shows the comparative properties of adhesives.

The data obtained show that butyl acrylate rubber adhesives containing butylphenol formaldehyde resin, glycerin

5 ester of rosin, polyterpene resin (control examples 1, 2 and 3), have low strength indicators in the delivery state, are inoperable during repeated gluing of scientific research institutes, change the decorative appearance of the fabric, have the character of peeling from cohesive to full transition of glue from the fabric surface on the plate and therefore cannot be used for the manufacture of decorative and finishing fabric of polyamide fiber with a sticky layer.

In comparison with the prototype and known adhesives, the proposed adhesive has a high durability at

0 repeated glueing, has a cross-ruptured nature of the gap, allows you to maintain the decorative appearance of the fabric.

The use of glue for the manufacture of decorative and finishing fabric with a sticky layer is a promising direction in the finishing of various residential premises.

1Lay be applied also 0 for making a tack layer transported on anti-adhesive paper backing.
