摘　　要：将碱厂白泥、造纸白泥、含油污泥等固体废弃物加工为橡胶填充剂是一种较好的资源化利用技术,但这些填充剂中往往残留有一定量的NaCl,可能对橡胶制品的性能造成一定影响。本文通过向天然橡胶中添加含有NaCl的填充剂研究了NaCl对橡胶制品性能的影响。实验表明,NaCl在橡胶加工过程中作为晶核起异相结晶作用,可提高橡胶的交联性和热稳定性;在实验的含量范围内,NaCl对填充剂粉体的分散性、硫化时间稍有影响,但橡胶交联性明显提高;硬度、拉伸强度、拉断伸长率等主要力学性能变化不大;老化后的橡胶力学性能基本不变,且部分力学性能高于对照样品。研究揭示,只要NaCl的含量控制在4%以内,基本不会对橡胶工程和橡胶制品性能产生影响;该研究成果有利于含NaCl固体废弃物资源化利用新技术的开发与应用。Comprehensive utilization will be the dominant technique for solid waste. Solid waste can be processed into rubber filler. NaCl in solid waste maybe influence the properties of rubber. This paper investigated the effects of NaCl on rubber property. NaCl can act as a nucleus of crystallization,resulting in the improvement of crosslinking and thermal stability of rubber. In the content range of added NaCl, NaCl can negatively reduce the dispersion of filler and delay the time of vulcanization, but can improve the crosslinking of rubber. Compared with the control group, mechanical and aging properties remain little change. The results show that less than 4% NaCl contents in fillers have little significant effect on rubber engineering and properties. This conclusion is in favor of the exploitation and research of comprehensive utilization technology on solid waste containing NaCl.
