纳米陶瓷粉改性苯并噁嗪树脂制备复合材料的方法
摘要：
本发明涉及高分子材料领域，具体地说是一种纳米陶瓷粉改性苯并噁嗪树脂制备复合材料的方法，按质量份计，将20～100份环氧树脂、5～30份纳米陶瓷粉在50～150℃下搅拌，待分散均匀后，加入50～100份苯并噁嗪树脂，0.5～20份触变剂，得到纳米陶瓷粉改性苯并噁嗪树脂制备复合材料。本发明采用苯并噁嗪树脂与纳米陶瓷粉、触变剂共混改性一步完成的方法，生产工艺简单，所得苯并噁嗪树脂制备的复合材料除了具有良好的热稳定性、力学性能、耐磨性、工艺性等性能外，还具有优异的硬度。
摘要（英）：

The invention relates to the field of high polymer materials and particularly relates to a method for preparing a composite material from nano ceramic powder modified benzoxazine resin. The method comprises the following steps: stirring 20-100 parts of epoxy resin and 5-30 parts of nano ceramic powder according to mass at 50-150 DEG C; and after uniform dispersion, adding 50-100 parts of benzoxazine resin and 0.5-20 parts of a thixotropic agent to obtain a composite material prepared from nano ceramic powder modified benzoxazine resin. According to the method, by adopting a method of one-step blending modification of the benzoxazine resin, the nano ceramic powder and the thixotropic agent, the production technology is simple, and the composite material prepared from the benzoxazine resin has good thermal stability, mechanical property, wear resistance, processing property and the like as well as excellent hardness.
