中文摘要：

分别枉预聚物体系中添加质量份数为0．3％，0．7％，1．0％，1．3％的坡缕石纳米（称为P纳米），原位合成坡缕石／桐油酚醛树脂（P／TPF）。用TEM观察纳米粒子在树脂中的分散状况，用SETARAM TG-DSC92-16热分析仪对合成的树脂进行了TG分析；将所合成的树脂分别制作成编织摩擦材料并在DMS-1试验机上对其摩擦学性能进行测试。结果表明：P纳米份数在0．3％～1．0％范围内P／TPF热失重率在240～600℃的中温区近于线性递减；当P纳米份数为1．0％时树脂的耐热性及其摩擦材料综合性能最佳，抗热衰温度可达280℃，200℃耐磨性最好，磨损率比无纳米桐油酚醛树脂摩擦材料提高15％。

英文摘要：

0.3%, 0.7%, 1.0% and 1.3% of the palygorskite nano particles （P nano-particles） were separately added in prepolymer. Palygorskite/tung oil phenolic resin was synthesized with in-situ method （it is called P/TPF）. The disperse state of nano-particles in phenolic resin was observed by TEM, the synthetic resin was carried out TG analysis by SETARAM TG-DSC92 16 thermal analyzer, and the synthetic resin was woven into the production of friction materials and the production was tested on its tribological behavior by DMS 1. The results show that thermal weight loss rate of the resin in the range 0.3%-1.0% ofP nano-pariclesis linear descending from 240℃ to 600℃. When the mass number of P nano particles is 1.0% in the resin, the integrative behavior of friction material is most optimized. Temperature of the heat resistance can be up to 280℃. Abrasion resistance of the friction materials is also best and its wear rate is an increase of 15% compared with tung oil phenolic resin without P nano-particles.
