摘要
采用氨基硼酸酯改性剂水乳液对高岭土进行湿法改性,研究改性时间及不同改性剂的影响.结果表明：湿法改性高岭土取代白炭黑后,胶料的优点是加工性能改善,压缩生热降低,弹性变好,拉断伸长率增大,混炼排胶温度和能耗明显降低,焦烧时间延长;缺点是定伸应力和撕裂强度下降,耐磨性能明显变差,密度和拉断永久变形稍有增大.高岭土湿法改性时间为10～15 min时效果较好.
Kaolin was modified by using water emulsion of amino boric acid ester, and the influence of modification time and modifier type was investigated. The results showed that, by using modified kaolin instead of silica in tire tread compound, the processing property of the compound was improved, the compression heat build-up was reduced, the resilience and elongation at break increased, the discharging temperature and energy consumption of mixing were obviously decreased, and the scorch time was extended. However, the modulus and tear strength of the vulcanizates decreased, the wear resistance decreased, and the density and permanent tensile set increased slightly. It was found that the optimized modification time was 10-15 minutes.
