FIELD: chemistry. ^ SUBSTANCE: invention relates to adhesive compositions based on polychloroprene rubber and can be used in the rubber industry when gluing together vulcanised rubber. The adhesive composition contains polychloroprene rubber nairit DP, butylphenolformaldehyde resin 101 K, water, zinc oxide, magnesium oxide, an organic solvent which is a mixture of ethylacetate and petroleum solvent and a modifier. The modifier used is trichloroethylphosphate or trichloropropylphosphate. Components of the composition are in the following ratio in pts. wt: polychloroprene rubber nairit DP - 90.0, butylphenolformaldehyde resin 101 K - 90.0 water - 3.0, zinc oxide - 5.0, magnesium oxide - 11.0, said organic solvent - 800.0, said modifier - 1.0-20.0. ^ EFFECT: invention increases strength when gluing together vulcanised rubber based on different types of rubber. ^ 2 tbl, 1 ex |
