采用复合助剂A作改性剂来改善阻尼橡胶的焦烧性能和溶解性能。研究结果表明,复合助剂A的含量为0.6%时所改性的阻尼橡胶具有较好的焦烧性能,能溶解的时间提高了4倍。同时,其改性阻尼橡胶的吸声效果提高了50%。改性阻尼橡胶的粘着强度有所下降,但能满足雷达的使用要求。
The compounding agent A is used as modification agent to improve the scorching and solubility property of damping rubber. The results show that as the compounding agent A content is 0.6%(mass), the scorching of the modified damping rubber is excellent, it increases by a factor of 5 in solvable time, and the sound absorbing effect of the modified damping rubber increases by a factor of 50%. Adhesion strength of the modified damping rubber is somewhat decreased, but it can meet the demand for application on radar.
