ADHESIVE PRODUCTION METHOD Russian patent published in 2003 - IPC

FIELD: chemical industry: production of adhesive. SUBSTANCE: invention presents the method of production of the adhesive based on a diisocyanate and epoxy resin, which mat be used for conglutination of a wood, a fabric and a paperboard. The method provides for interaction of 2.4-toluenediisocyanate with epoxy resin at presence of ε- caprolactam at a molar ratio of 2.4-toluenediisocyanate, epoxy resin, ε-caprolactam as (0.03- 1.1) : (0.25-1) : (1-8.2) accordingly, at presence of the catalytic agent of Na-salt of ε-caprolactam, and at the temperature of 180±5^°C. The invention allows to expand an arsenal of the adhesive agents, that are operational under lower temperature and have reduced cure time. EFFECT: the method is simple in realization, does not require large labor input and allows to produce adhesive based on industrially manufactured components, that promotes cost reduction of a product. 1 tbl, 3 ex
