FIELD: adhesive compositions.

SUBSTANCE: invention relates to compositions of adhesive compositions containing nitrile butadiene rubber, phenol-formaldehyde resin, chlorinated polyvinyl chloride resin, zinc oxide, magnesium oxide, silicon dioxide, ethyl acetate. 1,3-bis(3,5-dimethyl-4-nitroso-1H-pyrazol-1-yl)propane or 1,3-bis(3,5-dimethyl-4-nitroso-1H -pyrazol-1-yl)butane. The ratio of components in parts by weight is: nitrile butadiene rubber 100, phenol-formaldehyde resin 10-20, chlorinated polyvinyl chloride resin 10-20, magnesium oxide 1.0-3.0, zinc oxide 1.0-3.0, silicon dioxide 10 0-20.0, hardener and adhesion modifier 7.0-11.0, ethyl acetate 300.0-500.0. The composition increases the strength and durability of the adhesive bond.

EFFECT: range of application of glue for a wide range of glued materials is expanding.
