Description

This invention relates to the plastics industry, in particular to the development of adhesives for sticky films. Known adhesive for adhesive films, including perchlorovinyl resin, butylphenol-formaldehyde resin, carboxyl-containing isoprene rubber, rosin, solvent and plasticizer, for example, a mixture of chloroparaffin and Dioctylphthalate in the following ratio of components, weights: 6: 14: 4–12: 4: 4: 4: 4: 4: 4: 4: 4: 4; ..4-12: 40-80: 2-811. However, the adhesive layer of this adhesive has low adhesion stability and cohesive strength. The purpose of the invention is to increase the stability of adhesion and cohesive strength of the adhesive film layer. This goal is achieved in that the adhesive for adhesive films, including perchlorovinyl resin, butylphenol-formaldehyde resin, carboxyl-containing isoprene rubber, rosin, solvent, chloroparaffia and plasticator, as the last glue contains methyl 2- (4-methyldioxan-2-yl) - Ztil-1,3-diodiclane in the following ratio of parts, parts: Perchlorvinyl resin PSH-C6-14 Carboxyl-containing isoprene rubber16-24 Butylphenol-formaldehyde resin4-12 Rosin4-12 Chloroparaffin1-4 2-methyl- (4-methydio San- 2il) -ethyl-1,3.

Stir for 2.5-3 hours, t. Until the solution is completely homogenized, after which the composition is ready for use. Glue is applied to the substrate (a film of unplasticized polynnilhlornd 45-55 microns thick, or paper or foil). Drying is carried out at 30-40 ° € until the solvent is completely volatilized for 5-10 minutes.

 The resulting adhesive composition forms a loose layer which, when kept for 500 hours in open form, does not dry out, while the adhesive properties of the layer do not deteriorate. When samples are detached from various surfaces (steel-3, stainless steel, painted metal, glass, ceramics, wood) there is no cohesive failure of the adhesive layer.
