The invention relates to polychloroprene rubber single-packaging adhesives and can be used in chemical, engineering industries, and in consumer services for bonding rubber, leather, and rubber-fabric materials. Reducing the preparation time of the composition to 80-95 minutes, increasing the sedimentation stability of adhesive compositions, increasing the strength of adhesive joints is achieved by additionally adding water, phenyl- / -naphtylamine and a phosphorus-containing modifier — a mixture of alkyl phosphates, taken in a 1: 1 weight ratio in the form of 1 10 4% solution in ethyl acetate. Glue composition contains, by weight.h: polychloroprene rubber 14-20; p-tert-butylphenol formaldehyde resin in so pl. 75-85 ° C 0.8-16.0: indenkoumaron resin 0.01-3.0; rosin 0.01-1.0; zinc oxide 0.3-0.8; magnesium oxide 0.3-3.0; aerosol with a specific surface area of 150–200 m / g 0.01–2.0; water 0.1-0.4; phenyl- / -naphthylamine 0.01-5.0; the specified phosphorus-containing modifier (1 10 4% solution in ethyl acetate) 0.05-0.1; gasoline 31-29 and ethyl acetate 31-39.
