FIELD: gluing materials. ^ SUBSTANCE: invention relates to gluing compositions of constant stickiness and self-gluing materials based on aluminum foil, polymeric films and other backings designated for exploitation aircraft technique, automobile manufacture, ship building and others fields of technique at temperature from -60°C to +80°C. Proposed composition comprises isoprene rubber-3,4-polyisoprene rubber of molecular mass 120000-240000 Da with the content of vinyl links 83-88%, vaseline oil or low-molecular polybutadiene as a plasticizing agent, terpene-phenolic resin as an adhesion additive, and nefras as a solvent. Invention provides enhancing cohesion strength - resistance to dynamic and static shift - and adhesion - strength at separating to aluminum foil and aluminum alloys of the claimed composition, and enhancing shift strength and separating self-gluing material. ^ EFFECT: improved and valuable technical properties of composition. ^ 3 cl, 3 tbl, 3 ex |
