| titleOfInvention | A kind of siliceous modified, high temperature resistant cyanate ester resin, its preparation method and application |
| abstract | The present invention relates to a kind of siliceous modified, high temperature resistant cyanate ester resin, its preparation method and application, comprise the following steps：The mixed solution of hydroxy silicon oil, silane coupler and organic solvent is added into the mixed solution of tetramethylammonium hydroxide aqueous solution and polar solvent, then 4 ~ 8h of hydrolytie polycondensation at 5 ~ 40 DEG C obtains the silsesquioxane containing epoxy radicals through distillation；By silsesquioxane and cyanate ester resin containing epoxy radicals at 50 ~ 100 DEG C 1 ~ 8h of pre-polymerization, obtain modified cyanic acid ester resin；Modified cyanic acid ester resin and modified anhydride are well mixed, siliceous modified, high temperature resistant cyanate ester resin is obtained.The present invention improves the fragility of cyanate ester resin in intrinsic toughness reinforcing mode, without sacrificing the heat resistance of cyanate ester resin in itself, the High temperature-resistanresin resin composition for pultrusion that Tg is 240 270 DEG C can be prepared, with extremely excellent resistance to elevated temperatures and good cost advantage. |
