CPE/HEC共混型吸水膨胀橡胶的性能研究

Study on Water-Swellable Rubber of CPE/HEC Blends

采用CPE为橡胶基材,HEC为吸水树脂,机械共混法制备CPE/HEC吸水膨胀橡胶。研究了HEC不同含量时样品在干、湿态下的力学性能,对材料的吸水性能进行研究。结果表明,随着HEC含量的提高,材料的干、湿态力学性能均有所下降;吸水率随着HEC含量的提高逐步提高。

Water-Swellable Rubber （WSR） was prepared by blending chlorinated polyethylene （CPE） with Hydroxyl- Ethyl-Cellulose （HEC）. The mechanical properties, the water-swellable performance of the WSR with different HEC content were studied. The results indicated that the mechanical properties of WSR decreased gradually with increase of HEC, and the degree of water swelling increased remarkably, the water swelling performance of the WSR varied greatly at different temperature.
