FIELD: production of antipyrines, applicable in wood-working industry, as well as in building at carrying-out of preventive maintenance measures in fireproofing of products made of dry wood.
SUBSTANCE: the method consists in mixing of alumochromophosphate, non-ionogenic surface-active agent and polyamine, preliminarily neutralized by ortho-phosphoric acid to pH 6.0-8.0, used as polyamine is the aqueous solution of a product of general formula: 
, where: n=0.1 and m=0.1 at the following mass relation of components: alumochromophosphate: non-ionogenic surface-active agent: polyamine equal to (20-90):(0.01-0.5):(10-80).
EFFECT: produced wood materials of the first group of fireproofing efficiency at reduced consumption of antipyrine.
