| 摘 要： | 本文对采用特殊加工工艺使聚丙烯腈浆粕均匀地包覆在聚丙烯腈短切纤维的表面形成的复合型浆粕在摩擦、密封材料中的应用进行了初探。结果发现，复合型浆粕用于摩擦材料中，与树脂基体间的粘合性能优异，材料强度较高，不易剥落，具有较稳定的摩擦磨损性能；用于无石棉密封橡胶板，制得的密封板均匀、有弹性、强度高、耐热。聚丙烯腈复合型浆粕取代石棉或芳纶浆粕用于增强摩擦材料、密封材料等复合材料中，具有优异的综合使用性能和加工性能，具有较高的性价比。

| Abstract: | The properties of the friction/gasket materials reinforced by a polyacrylonitrile compound pulp, in which the polyacrylonitrile short-cut fiber was uniformly wrapped around by the polyacrylonitrile pulp by a special technology was studied. The short-cut fibers provided the mechanical strength and the highly fibrillated pulp entrapped and held other components and also avoided balling for entanglement between the fibers. The results showed that the friction materials reinforced by the compound pulp had smooth surface, excellent friction and wear properties and the gasket materials reinforced by the compound pulp had high strength, good elasticity and heat-resistance. |
