LOW TOXIC ADHESIVE COMPOSITION ON THE BASE OF CARBAMIDE-FORMALDEHYDE RESIN WITH ALUMINOSILICATE FILLER

摘要

FIELD: production of adhesive compositions; in furniture industry and veneer industry for adhesion of splint-slab plates and other woody materials. SUBSTANCE: adhesive on the base of carbamide-formaldehyde resin comprising hardening agent is modified by aluminosilicates. Thus free amount of formaldehyde is sorbed of resin, due to this fact toxicity of plate materials is decreased by a factor of 10. EFFECT: decreased toxicity of plate materials; increased strength of adhesive joint; decreased hardening time; increased duty of adhesive devices. 3 tbl
