摘　　要：研究废旧轮胎湿法水磨胶粉在天然橡胶(NR)/顺丁橡胶(BR)并用配方体系中的应用。结果表明:以湿法水磨胶粉部分替代炭黑N330,胶料的硬度、定伸应力和拉伸强度明显降低,拉断伸长率和回弹值明显增大,60℃时的损耗因子减小,动态拉伸储能模量大幅降低;在NR/BR并用胎圈胶配方中以30份湿法水磨胶粉替代5~10份炭黑N330,胶料的物理性能和动态性能在相同水平,同时可降低原材料成本,利于环保。The application of wet milled rubber powder of waste tire in the natural rubber(NR)/butadiene rubber(BR)blended formula system was studied.The results showed that when the carbon black N330 was partially replaced by wet milled rubber powder,the hardness,modulus and tensile strength of the compound decreased significantly,the elongation at break and resilience increased significantly,the loss factor at 60℃decreased,and the dynamic tensile storage modulus decreased significantly.In the formula of NR/BR blend bead compound,using 30 phr wet milled rubber powder to replace 5~10 phr carbon black N330,the physical properties and dynamic properties of the compound were at the same level,and at the same time,it could reduce the cost of raw materials and was good for environmental protection.
