为了消除石棉基增强摩擦制动材料对环境和人体的危害，以α－氨丙基三乙氧基硅烷为活化剂，对取自粉煤灰的漂珠进行活化处理，再以其作为基础增强填料替代石棉，成功地研制出新型无石棉自增强摩擦材料．这种新材料的基本组成除增强剂漂珠外，还有树脂－橡胶粘结剂和摩擦改善剂等．检测和试用结果证明，在给定的试验条件下，与石棉增强的摩擦材料相比，这种无石棉自增强摩擦材料的摩擦学性能好，制动时间短，偶件的磨损很小，而且漂珠价廉易得，并为粉煤灰的再生利用找到了一条新途径
In order to eliminate the harm of asbestos-based friction friction material to the environment and human body, α-aminopropyltriethoxysilane is used as an activator to activate the floating beads obtained from fly ash and then to enhance it as a basis Filler instead of asbestos, successfully developed a new non-asbestos self-reinforced friction material. The basic composition of this new material in addition to reinforcing agent floating beads, there are resin - rubber binder and friction modifier. The results of testing and testing prove that the asbestos-free self-reinforced friction material has better tribological properties, shorter braking time and less even wear than the asbestos-reinforced friction material under the given test conditions, and Floating beads cheap and easy to get, and for the recycling of fly ash to find a new way
