HYDROGEL FOR FIREPROOF INTERLAYERS IN MULTILAYER FIREPROOF GLASING

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to fireproof translucent building structures. To obtain fireproof interlayers, the multilayer fireproof glasing uses hydrogel, having the following components in wt %: polyacrylic acid and/or alkali metal salts thereof 30-70; polyatomic alcohol, mainly polyvinyl alcohol 0.5-10; water 7.9-57.9; peroxide-type polymerisation photoinitiator 0.06-0.4; flame retardant selected from phosphorus compounds in amount of 0.5-7.;EFFECT: high fire-resistance.;7 cl, 1 tbl, 1 dwg
