发明名称 EPOXY ADHESIVE COMPOSITION
摘要 <p>1416361 Epoxy adhesive composition USS ENGS & CONSULTANTS Inc 19 Jan 1973 [19 Jan 1972] 2957/73 Heading C3B An epoxy resin adhesive composition comprises 15-60% wt. glycidyl polyether of a dihydric phenol having an epoxy equivalency greater than 1, 25-60% wt. filler, 1-7% wt. flexibilizer, and 0À8 to 17% wt. two component curing agent comprising (a) 0À5 to 14% wt. of an amine hardener of the formula where n and x are each 2-7, and (b) 0À3 to 3% wt. of a rigidifying tertiary amine catalyst containing at least 6 carbon atoms, and an aromatic dihydroxy compound, and optionally 10-40% wt. of an aromatic oil, preferably a coal tar fraction, boiling in the range of 500-900‹ F., and 0À2 to 2% wt. of a silicone or organosilane adhesion promoter. The preferred aromatic dihydroxy compounds are resorcinol and bisphenol-A and are preferably used in an amount of 0À5-10% wt. Preferred fillers are talc, silica, dolomite, anhydrous calcium sulphate and aluminium silicate. Preferred flexibilizers are poly- (vinylalkyl ether) where the alkyl group contains 1-5 carbon atoms, rosin ester, solid polyamide resin, or a copolymer of styrene and buta. diene, these flexibilizers having a molecular weight of 500-200,000. The preferred tertiary amine catalysts are tri-(dimethyl-amino-methyl) phenol, dimethylaminomethyl phenol and benzyldimethylamine. In Example 3 an adhesive composition is prepared from an epoxy resin which is the condensation product of bisphenol A and epiehlorohydrin, tale, a gellant which is the reaction product of dodecylamine and bentonite, an amine hardener of the formula H 2 N(C 4 H 8 )O(C 4 H 8 )NH 2 , a tri - (dimethylaminomethyl) phenol catalyst, resorcinol and the adhesion promoter in n-butyl alcohol.</p>
