FIELD: chemistry. ^ SUBSTANCE: self-adhesive material has a base - aluminium foil and an adhesive composition applied on said base, having permanent stickiness, containing the following in pts.wt: isoprene-styrene thermoplastic elastomer with 5-7% styrene content 100, an adhesive agent - terpene phenol resin, terpene styrene resin or mixture thereof with perchlorovinyl resin 10-15, plasticiser - epoxidated vegetable oil 7-10 and an organic solvent - ethyl acetate or mixture thereof with benzine and methylene chloride 250-550. The adhesive composition can additionally contain chlorinated polyisoprene rubber in amount of 2-5 pts.wt. The ratio of the thickness of layers the base: adhesive composition is equal to 1:(0.25-1). The self-adhesive material is meant for repair and use at temperatures ranging from -60 to +80C in aviation, in motorcar and shipbuilding and other engineering fields. ^ EFFECT: high adhesion strength, cohesive strength of the self-adhesive material, high resistance to static shearing at high temperatures, low labour input and power consumption when carrying out repair works on the surface of aircraft frames and other structures. ^ 3 cl, 2 tbl, 5 ex |
