EPOXIDE COMPOSITION Russian patent published in 2002 - IPC

FIELD: chemical technology of epoxy compounds. SUBSTANCE: invention relates to making rapid-hardening epoxide compositions for hot molding used as a binding agent for the production of composite materials and articles, for example, reinforced plastics by the pultrusion method. Epoxide composition comprises, mas. p. p.: at least one epoxy resin or its mixture with epoxy resin containing two or more epoxy groups, 100; anhydride hardening agent, 75-100 and tertiary amine of the general formula: where R₁,R₂,R₃ mean aliphatic hydrocarbon radicals one of that has 8-20 carbon atoms and others have one or two carbon atoms or a mixture of tertiary amines as a basic hardening catalyst. The composition does not require the additional addition of modifying agents and additions. EFFECT: simplified composition, improved technological effectiveness and working life of binding agent. 4 tbl
