摘要
研究了α-甲基丙烯酸锌(MAA一Zn)对NBR/木质素(100/100,质量比)硫化胶性能的影响。结果表明,加入1.5~5.0份MAA-Zn,可提高硫化胶的100%定伸应力、硬度和抗压缩永久变形能力,但对其他力学性能影响甚微。经分析可知,MAA-Zn还可以降低硫化反应活化能、提高硫化胶的交联密度和耐热老化性能。
The effect of unsaturated carboxylate zinc methacrylate(MAA-Zn)on the properties of NBR/lignin(100/100, mass ratio)vulcanizate was studied.The results showed that the modulus at 100%,Shore hardness and resistance to compression permanent set increased by adding 1.5~5.0 phr of MAA-Zn without harm to the other properties of vulcanizate.MAA-Zn could also decrease the activation energy of vulcanization,and increase the crosslinking density and the resistance to heat aging of vulcanizate.
