METHOD OF PRODUCING FIREPROOF COATING FOR RUBBER Russian patent published in 2015 - IPC C09D123/34 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of fire-proofing materials by depositing a fire-proof coating. A method of producing a fireproof coating for rubber by applying a coating based on chlorosulphonated polyethylene, an organic solvent - toluene, coupled with a phosphorus-containing compound, and subsequently drying the coating at room temperature. The phosphorus-containing compound used is a phosphorus-boron-nitrogen-containing oligomer which is obtained by reacting methylphosphite borate, epoxy resin ED-20 and aniline in weight ratio of 2.5:1:2.5 in amount of 0.5-3.0 pts.wt per 100 pts.wt coating. The coating is applied in a layer with thickness of 1 mm. The coating is dried for a day.

EFFECT: invention improves fire-proofing of the coating and high adhesion to rubber.
