Method for producing cyanuric acid-modified phosphorus-containing epoxy resin, resin composition containing the cyanuric acid-modified phosphorus-containing epoxy resin, and curing thereof

摘要

In the production of cyanuric acid-modified phosphorus-containing epoxy resin flame-retardant obtained by modifying an epoxy resin with a cyanuric acid and phosphorus compound, and enables the production of a short time, and the residual cyanuric acid is extremely small, to provide a manufacturing method of cyanuric acid-modified phosphorus-containing epoxy resin capable of obtaining a cured epoxy resin having excellent physical properties. phosphorus compounds, cyanuric acid, and an epoxy resin to a process for the preparation of cyanuric acid-modified phosphorus-containing epoxy resin obtained by reacting, as essential components, a specific phosphorus compound, for cyanuric acid 1 mol and the phosphorus compound to 2.5 to 50 mol, manufacturing method, and then the resulting phosphorus content of cyanuric acid-modified phosphorus-containing epoxy resin is 1.0 to 5.0 wt%, nitrogen content of 0.1 to 2.0 wt%, and phosphorus-containing sum of incidence and nitrogen content is a resin composition and a cured product containing a curing agent and cyanuric acid-modified phosphorus-containing epoxy resin is 2.5 to 5.5 wt%.
