ABSTRACT:
A method of producing furan-epoxy powder-like binder comprising reacting the product of the polycondensation of epichlorohydrin with diphenylpropane (100 weight parts) with a ketone containing a furfurylidene group (33-200 weight parts) and a nitrogen-containing compound (8-100 weight parts). As examples of the ketone containing a furfurylidene group monofurfurylideneacetone, difurfurylideneacetone, difurfurylidenecyclohexanone, a mixture of monofurfurylideneacetone with difurfurylideneacetone in a ratio (weight parts from 1:1 to 1.4:1; 1,9-di-(.alpha.-furyl)nonanetetracene-1,3,6,8-one-5 or 1,5 -di-(.alpha.-furyl)-2,4-dimethylpentadiene-1, 4-one-3 may be mentioned. Triethanolamine, 3-methyl-5-furylpyrazoline, trifurylimidazoline, hexamethylenediamine, and low molecular polyamides with molecular weight of 2000-10000 or polyethylenepolyamine with molecular weight of 1000 are used as a nitrogen-containing compound. The reaction is performed at 130.degree.-200.degree. C. in the presence, if necessary, of trifurfurylborate (1-12 weight parts). The obtained product is cooled down to a temperature not exceeding 30.degree. C. and ground to a powder state. The furan-epoxy binder does not cake for 60 days and retains its properties upon storing for a long period of time (up to 12 months). Heat distortion temperature of polymer materials based on the above-cited binder is 250.degree. C. according to the Vicat method. Polymer materials formed from said binder can be combustible and incombustible or display ability to self-extinction.
