摘　　要：用超支化聚硅氧烷修饰纳米SiO2粒子(HBPSi-SiO2),将其加入到苯并恶嗪(BOZ)树脂中制备了BOZ/HBPSi-SiO2复合材料,并与普通处理的纳米SiO2(Nano-SiO2)进行比较,研究了该复合材料的摩擦性能。结果表明,HBPSi-SiO2具有比Nano-SiO2更优异的减摩抗磨效果。相对于纯BOZ树脂,BOZ/Nano-SiO2复合材料的磨损率降低了59.4%,而BOZ/HBPSi-SiO2复合材料的磨损率降低了87.2%,摩擦系数也有所降低。SiO2 nano-particle was modified by hyperbranched polysiloxane （ HBPSi ）, and HBPSi-SiO2 was put into benzoxazine （ BOZ ） resin to prepare BOZ/HBPSi-SiO2 composite. The tribological properties of the composite were studied and compared with the BOZ composite filled conventional treated nano-SiO2 （ Nano-SiO2 ）. The results showed that HBPSi-SiO2 had excellent friction-reduction and anti-wear performance than the Nano-SiO2. Compared with the matrix, the wear rate of BOZ / Nano- SiO2 composite decreased by 59.4%, and that of BOZ/HBPSi-SiO： composite decreased by 87.2%, and the friction coefficient of the compositewas also reduced.
