AI Technical Summary
Technical Problem
In the existing technology, mercapto acid monomers have poor compatibility and dispersibility in high-viscosity rubber matrices, which affects the strength, wear resistance, wet skid resistance and heat generation performance of tire tread rubber.
Method used
A rubber processing modifier was prepared by premixing mercapto acid monomers, matrix materials, and silica. This modifier significantly improved the compatibility and dispersibility of mercapto acid monomers with the rubber matrix and was used to prepare tire tread rubber.
Benefits of technology
While ensuring the high strength, wear resistance, and wet skid resistance of the tire tread compound, it significantly reduces heat generation and rolling resistance, thereby improving fuel economy.
