摘要: 运用多步接枝工艺,实现了掺杂TiO2粒子(M系列)的表面改性,制备出系列M粒子-氰酸酯树脂(CE)复合材料。研究了复合材料的摩擦力学性能及洛氏硬度的变化。结果表明,加入少许M系列粒子(质量分数<4%)后,可以使得氰酸酯树脂(CE)的摩擦力学性能得到改善。当复合材料中M-2粒子的含量为3wt%时,摩擦系数下降36%,摩擦消耗下降约60%,增强了复合材料的耐磨性;当M-2粒子的含量为4wt%时,复合体系洛氏硬度提高了10.4%。

Abstract: The surface modification of Nd-cyanate ester was realized by doping titanium dioxide (M Series) through the multi-step grafting method. A series of M series particles/cyanate ester (CE) composites were prepared. The friction properties and Rockwell hardness of the composites were studied. The result shows that the friction performance of CE can be improved by adding a little M particle (mass fraction<4%). When the M-2 particle mass fraction is 3wt%, the friction coefficient of the composite can be decreased by about 36%, and the friction consumption can be decreased by about 60%. The wear resistance of the composites was enhanced. When the M-2 particle content is 4wt%, the composite system Rockwell hardness is increased by 10.4%.
