Reaction Steps

150 g ammonium polyphosphate (EXOLIT 263) was suspended in 600 ml methanol in a stirring apparatus made of glass, and the suspension was heated to gentle boiling. Next, a methanolic epoxide resin/epoxide resin hardener-solution which was prepared by dissolving 3 g BECKOPOX EP 128 and 3 g BECKOPOX VEH 2130 in 100 ml methanol was added dropwise within 15 minutes. For hardening the epoxide resin, the suspension was stirred for 2 hours while the methanol boiled gently. After cooling, the whole was filtered and the resulting filter cake was dried at 110° C. in a stream of nitrogen. 154 g treated ammonium polyphosphate which contained 3.5 mass % epoxide resin was obtained.
