N-thiomorpholinyl-terminated mercaptosilane coupling agent and synthesis method and application thereof

The invention belongs to a silane coupling agent, and particularly relates to an N-thiomorpholine-based terminated mercaptosilane coupling agent and a synthesis method and application thereof. The N-thiomorpholinyl terminated mercaptosilane coupling agent has a structure as shown in a formula (I) which is described in the specification. According to the N-thiomorpholinyl-terminated mercaptosilanecoupling agent as shown in the formula (I), the interaction between the polymer and the filler can be significantly enhanced, the hysteresis loss of the rubber material can be reduced, the heat generation can be reduced, the Payne effect of the rubber material can be reduced, and the dispersibility of the white carbon black can be improved so as to reduce the oil consumption and the carbon dioxideemission during the tire driving process and enhance the wear resistance of the tire; meanwhile, the N-thiomorpholinyl-terminated mercaptosilane coupling agent has the effect of promoting vulcanization and can reduce energy l
