新型硅烷偶联剂IMLV在绿色轮胎胎面胶中的应用

The application of a new silane coupling agent IMLV in the green tire tread compound was studied and compared with the traditional coupling agent Si69. The results showed that when coupling agent IMLV was used to replace coupling agent Si69，the Mooney scorch time of the compound was prolonged，and the processing safety and stability were improved. Meanwhile，the hardness，modulus，tensile strength，tear strength and tensile set of the vulcanizate were equivalent，the elongation at break increased，the wear resistance was improved，the dispersion at break of silica in rubber matrix was better，the loss factor of the vulcanizate decreased，and the rolling resistance was reduced.
