黏合剂对汽车尾气净化器衬垫性能的影响

Effects of Adhesives on the Properties of Vehicle Exhaust Purifier Pad

结合原料纤维的特点,对制作汽车尾气净化器衬垫所使用的黏合剂种类和用量进行了研究.实验结果表明:成膜强度高、柔韧性好的黏合剂可以为衬垫提供良好的强度、柔韧性和耐折性能.B-3丙烯酸类黏合剂可以赋予衬垫较好的强度性能;且B-3丙烯酸类黏合剂在海泡石/玻璃纤维与海泡石/陶瓷纤维体系中的用量分别以6%、8%为最佳.

According to the characteristic of different fibers, a deep investigation and study on selection and dosage of adhesives used in the pad of vehicle exhaust purifier were carried out. The results showed that adhesive with high strength and good flexible, could provide good strength, flexible and blending strength for the pad. Acrylic adhesive （B-3）could be the better choice to improve the mechanical properties of the pad, and the optimal dosages of adhesive are 6% and 8% in the G Ⅱ （Sepiolide/glassfiber）and CIV （Sepiolide/ceramic fiber）systems.
