- Dithiophosphate radical terminated mercaptosilane coupling agent as well as synthesis method and application thereof
-
The invention belongs to a silane coupling agent, and particularly relates to a dithiophosphate radical terminated mercaptosilane coupling agent as well as a synthesis method and an application thereof. The dithiophosphate radical terminated mercaptosilane coupling agent has a structure as shown in a formula (I) which is described in the specification. According to the dithiophosphate radical terminated mercaptosilane coupling agent shown in the formula (I), the interaction between a polymer and filler can be enhanced, the hysteresis loss of a rubber material is remarkably reduced, the Payne effect of a rubber material is reduced, and the dispersity of white carbon black is improved, so that the oil consumption and the emission of carbon dioxide in the tire driving process are reduced, andthe wear resistance of the tire is enhanced; meanwhile, the dithiophosphate radical terminated mercaptosilane coupling agent provided by the invention has the effect of promoting vulcanization, and can reduce the energy loss in the vulcanization process.
