ADHESIVE COMPOSITION Russian patent published in 2024 - IPC C09J111/00 C09J161/08 

FIELD: adhesives.

SUBSTANCE: adhesive composition includes polychloroprene rubber Nairit DP, butylphenol-formaldehyde resin 101 K, water, zinc oxide, magnesium oxide, an organic solvent and a phosphorus-nitrogen-comprising modifier. The organic solvent is a mixture of ethyl acetate and nefras. The product of the interaction of dicyandiamine with dimethylphosphite in a phosphoric acid environment applied to carbon microfibres is used as a phosphorus-nitrogen-comprising modifier. The modifier is applied to carbon microfibres in the form of a 5 wt.% aqueous solution. The mass ratio of carbon microfibres to an aqueous solution of the modifier is 10:1-5.

EFFECT: increased adhesion of the adhesive composition to rubber and the heat resistance of the adhesive joint.
