METHOD OF MAKING FIREPROOF COATING FOR FIBRE-GLASS Russian patent published in 2014 - IPC C09D127/24 

FIELD: chemistry.

SUBSTANCE: method can be used in different fields of industry for fireproofing fibre-glass. The method of producing a fireproof coating for fibre-glass by applying a coating based on chlorinated polyvinyl chloride resin, an organic solvent coupled with foaming filler, and subsequently drying the coating at room temperature. The organic solvent used is a mixture of butyl acetate and acetone in ratio of 1:1; the foaming filler used is a phosphorus-boron-nitrogen-containing oligomer which is obtained in advance by reacting methyl phosphite borate, epoxy resin ED-20 and aniline in weight ratio of 2.5:1:2.5, in amount of 2.5-7.5 pts.wt per 100 pts.wt coating. The coating is deposited in a layer with thickness of 1 mm and dried for 2 days.

EFFECT: invention enables to obtain a coating with a smaller thickness, cuts the drying time of the coating and provides high fire-protection for fibre-glass.
