摘　　要：用硫化改性剂和废轮胎胶粉制备了全胶粉弹性体.讨论了改性剂用量、炭黑用量、加工工艺及加工助剂对全胶粉弹性体物理机械性能的影响.实验发现硫化改性剂用量为2份;炭黑用量15份;加工油用量小于2份,可以得到较好性能的全胶粉弹性体,拉伸强度达7.9 MPa,断裂伸长率为315%,超过了再生胶的国标(拉伸强度6 MPa).同时对全胶粉弹性体的微观形貌及断裂行为也进行了讨论.Ground Tire Rubber（GTR） was reclaimed by using the strong shearing force and the reclaiming agent in less than ten minute. It was found that adding 2 phr reclaiming agent, 15 phr carbon black,2 phr naphthenic oil,the obtained elastomer had the best mechanical properties. The tensile strength was 7.9 MPa,elongation at break was 315%,the tear strength was 28 N/m. The microstruture of elastomers were also been detected by SEM.
