METHOD FOR PRODUCING CYANURIC ACID-MODIFIED PHOSPHORUS-CONTAINING EPOXY RESIN, RESIN COMPOSITION CONTAINING CYANURIC ACID-MODIFIED PHOSPHORUS-CONTAINING EPOXY RESIN, AND CURED PRODUCT OF SAME

摘要

the invention, cyanuric acid and the compound used in the epoxy resin-modified In cyano flame retardant press acid modification is contained in the preparation of the epoxy resin, allowing the production of a short time, and also very low residual cyanuric acid, cyanuric to obtain an epoxy resin cured product having excellent physical properties the acid-modified It provides a method for producing epoxy resin. The compound, cyanuric acid and an epoxy resin by reacting the resulting cyanuric as an essential component acid-modified phosphorus-containing production process of the epoxy resin, 2.5 to 50 moles, and the phosphorus compound with respect to the particular of the compound cyanuric acid per mol, method of producing cyanuric acid-modified phosphorus-containing epoxy resin, and the resulting therefrom the content of 1.0 to 5.0% by weight, a nitrogen content of 0.1 to 2.0 mass%, and the total of the content and the nitrogen content from 2.5 to 5.5% by weight of cyanuric a phosphorus-containing acid-modified resin composition and its cured product of an epoxy resin and a curing agent.
