摘要
考察了甲基丙烯酸锌(Zn(MAA)2)添加方式对CM性能的影响。结果表明,Zn(MAA)2用量相同时,原位生成Zn(MAA)2的胶料力学性能优于直接添加Zn(MAA)2的胶料;随着Zn(MAA)2用量的增大,胶料硫化程度明显提高,力学性能得到明显改善,老化后的拉伸性能保持率也得到改善;Zn(MAA)2用量在30～40份之间时,拉伸强度可达到19.7MPa,撕裂强度提高3倍以上。
Effects of different adding methods of Zinc Dimethaerylate[Zn（MAA）2 ] on the prperties of chlorinated polyethylene rubber （CM） were investigated. The results showed that the comprehen- sive mechanical properties of CM vulcanizate with Zn（MAA）2 generated in-situ was superior to that with Zn（MAA）2 added directly when the amount of Zn（MAA）2 addition was equal. The crosslinking degree of CM vulcanizate was significantly improved with the increase of Zn（MAA）2 amount, and the mechanical properties and the tensile properties retention became good. The tensile strength could reach 19.7MPa,and the tear strength also increased more than three times when Zn（MAA）2 content was 30-40 phr.
