摘要： 试验研究纳米活性碳酸钙在轮胎中的应用效果。结果表明,在斜交轮胎胎侧和胎体帘布胶料配方中加入5～8份纳米活性碳酸钙,并适当调整配方中炭黑和软化剂用量,可改善胶料的物理性能和工艺性能;在子午线轮胎胎面胶配方中加入4份纳米碳酸钙,胶料的抗撕裂性能提高,耐磨性能和其它物理性能相当,挤出工艺性能得到改善;同时可以降低生产成本,具有一定的经济效益。 The application of an active nano-calcium carbonate in tire was experimentally investigated.The results showed that the processibility of rubber compound and the physical properties of vulcanizate improved by adding 5~8 phr active nano-calcium carbonate in the sidewall and carcass ply compounds of bias ply tire and adjusting the addition level of carbon black and softener properly;the comparable tear strength,abrasion resistance and other physical properties of vulcanizate and the better extrudability were ...
