基于两种丁腈橡胶复合填料的高性能离合器摩擦材料

High Performance Winding Clutch Friction Materials Based On Two Kinds Of NBR Emulsoid

本文提出了以丁腈乳胶改性水基酚醛树脂作粘合剂,分别以玻璃纤维和复合包芯纱纤维作为增强材料,采用两种新型丁腈复合填料作主要填料制备高性能离合器摩擦材料的试验方法。两种新型复合填料分别为含9%硫化丁腈橡胶和含20%未硫化丁腈橡胶。试验表明:当两种新型复合填料按1:1的比例加入,即丁腈橡胶含量在16%左右时,制备出的摩擦材料具有良好的摩擦磨损性能、适中的硬度、良好的冲击强度及较低的噪音。

It is put forward in this paper that a new technologic method to prepare the winding clutch friction materials by using water-based phenolic resin modified by NBR emulsoid as adhesive , glass fiber , core-spun yarn as the reinforcing fibers and the two new NBR composite filler as the main filler. Two new type of composite filling materials were 9% of the sulfide- containing nitrile rubber and 20% did not contain nitrile rubber vulcanization. Experiments indicate that,when the two new composite filler mixed at the ratio of 1：1, the clutch friction material has good friction and wear property ,whether using glass fiber or core-spun yarn as the reinforcing fibers, we can get high quality friction material with rather inpact intensity, moderate rigidity, extremely stable friction coefficient , relatively low wear rate and low noise and vibration when using the method mentioned in this paper.
