胶乳-悬浮液共沉法天然橡胶/埃洛石纳米管复合材料的结构与性能

郭宝春  类延达  邹全亮  刘明贤  杜明亮  贾德民 

摘 要:利用天然橡胶(NR)胶乳和埃洛石纳米管(HNTs)悬浮液的负电稳定性,采用胶乳-悬浮液共沉法制备了NR/HNTs复合材料,并对其硫化特性、微观结构、力学性能以及动态力学性能进行了研究.结果表明,HNTs的引入可促进NR的硫化反应,随HNTs用量的增加,焦烧期和正硫化时间缩短;HNTs在复合材料中的分散性极佳;随着HNTs用量的增加,纳米复合材料的定伸应力和邵尔A硬度明显增大,扯断伸长率有所下降,综合力学性能在20份时最好;随着HNTs用量的增加,纳米复合材料的玻璃化转变温度略有升高,转变区的损耗因子明显下降.
