摘要
研究改性碳纳米管对三元乙丙橡胶硫化特性、物理性能和粘合性能的影响。结果表明:随着改性碳纳米管用量的增大,胶料的交联密度先增大后减小,门尼粘度增大,Payne效应增强,加工性能变差;硫化胶的拉伸强度先增大后减小,撕裂强度呈增大趋势;粘合性能先提高后下降,改性碳纳米管用量为6份时粘合力最大。
The effects of modified carbon nanotube on the cure characteristics,physical properties and adhesion properties of EPDM were investigated. The results showed that,with the increase of the amount of modified carbon nanotubes,the cross-link density of the compound first increased and then decreased,while Mooney viscosity increased,Payne effect was enhanced and the processing property became worse.The tensile strength of the vulcanizate first increased and then decreased,and tear strength increased. The adhesion properties of the vulcanizate were improved first and then declined,and the maximum adhesion was obtained when the amount of modified carbon nanotube was 6 phr.
