FIELD: chemistry. ^ SUBSTANCE: invention relates to adhesive compositions based on chloroprene rubber and can be used in the rubber industry when gluing together vulcanised rubber. The adhesive composition contains polychloroprene rubber nairit NT, butylphenolformaldehyde resin 101 K, thiuram, zinc oxide, magnesium oxide, a modifier and an organic solvent which is a mixture of ethylacetate and petroleum solvent. The modifier used is methylphosphite borate. Components of the composition are in the following ratio in pts. wt: polychloroprene rubber nairit NT - 100.0, butylphenolformaldehyde resin 101 K - 90.0, zinc oxide - 5.0, magnesium oxide - 12.0, thiuram - 2.0, said organic solvent - 800.0, methylphosphite borate - 10.0-30.0. ^ EFFECT: invention increases strength when gluing together vulcanised rubber based on different types of rubber. ^ 2 tbl, 1 ex |
