ADHESIVE COMPOSITION (VARIANTS) Russian patent published in 1998 - IPC

FIELD: gluing together various materials. SUBSTANCE: adhesive composition comprises epoxy diane resin, aminophenol hardening agent and modifying agent. Aminophenol hardener represents itself product of transamination of mixture of 2,2,6-bis-, 2,4,6-tris-(dimethylaminomethyl)phenol with mixture comprising diethylene triamine, triethylene tetramine and N-β-aminoethyl piperazine. Polyoxypropylene polyol (its molecular weight being 3500-5000) and flotation agent (being high boiling product of 4,4-dimethyl dioxane production) or product on the base of mixture of dioxane alcohols and high boiling ethers thereof (which is prepared by distillation of light fraction having boiling point 115-160 C, the process takes place at 5-10 mm Hg, flotation agent being used as origin material) is used as mentioned above modifying agent. Proposed composition may comprise aliphatic epoxy resin on the base of diol and polyol. Composition is affected by hardening within 24 h at room temperature. EFFECT: improved adhesive properties of composition. 3 cl, 1 tbl
