摘　　要：采用硅橡胶、丁腈橡胶共混改性酚醛树脂黏结剂,利用湿法工艺制备纸基摩擦材料试样。借助湿式摩擦性能试验机以及扫描电镜研究橡胶改性酚醛树脂黏结剂对纸基摩擦材料摩擦磨损性能和表面形貌的影响。实验结果表明:与单纯采用酚醛树脂黏结剂相比,使用丁腈橡胶-酚醛树脂共混黏结剂提高了纸基摩擦材料的静摩擦因数,但动摩擦因数和耐磨性能有所降低;而使用硅橡胶-酚醛树脂共混黏结剂不仅提高了纸基摩擦材料的动、静摩擦因数,也使其耐磨性能有所提升。The paper-based friction materials were fabricated by impregnated the phenolic resin adhesive modified by ni-trile butadiene rubber and silicon rubber.The tribological properties of the paper-based friction material were investigated on a wet friction tester and the surface morphologies were analyzed using a scanning electron microscope.Experiment re-sults show that,compared with the phenolic resin adhesive,the blending adhesives of phenolic resin and nitrile butadiene rubber can improve the static friction coefficient of paper-based friction materials,but the dynamic friction coefficient and abrasion performance of the friction materials are declined.However,the blending adhesives of phenolic resin and silicon rubber can enhance tribological properties of paper-based friction materials and improve its abrasion performance.
