摘　　要：采用丁腈橡胶改性酚醛树脂,研究了改性产物的冲击韧度及其摩擦磨损性能。结果表明:橡胶改性酚醛树脂具有强度大且耐温性好的特点,尤其在摩擦磨损性能上比纯酚醛树脂有较大的改善。在该试验条件下,丁腈橡胶含量在8%左右较适宜。Phenolic resin was modified by the nitrile rubber, and its properties of the impact strength and friction performance were investigated. It was shown that the modified phenolic resin was characterized with high strength and excellent heat resistance compared with the pure phenolic resin, especially a significant improvement in friction property. It is recommended that the NBR content of friction materials should be around 8%.
