METHOD OF MAKING FIREPROOF COATING FOR FIBRE-GLASS Russian patent published in 2013 - IPC C09D5/18 C09D127/24 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of fireproofing fibre-glass materials. The method of making a fireproof coating for fibre-glass involves depositing onto the fibre-glass a coating which contains a perchlorovinyl resin, an organic solvent - mixture of butyl acetate and acetone in ratio of 1:1 and a foaming filler in form of phosphorus-boron-chlorine-containing oligomer, which is obtained by reacting methyl phosphite borate with epichlorohydrin in weight ratio of 3.5:3, in amount of 8.5-11.5 pts.wt per 100 pts.wt coating composition, and then drying the coating at room temperature for 2 days, wherein the coating composition is deposited in a layer with thickness of 0.5-0.7 mm.

EFFECT: invention cuts the drying time of the coating, reduces thickness of the coating and improves fibre-glass fireproofing.
