Abstract

The invention relates to a preparation method of an antiskid tread rubber material and belongs to the technical field of rubber materials. The preparation method comprises the steps: compounding kaoline serving as a raw material with zinc powder, mutually winding mullite whiskers prepared by carrying out high-temperature calcination on kaoline and whiskers prepared from zinc oxide to form granularaggregates, mutually winding the whiskers, and then, carrying out binding by using resin to form agglomerated particles to be dispersed into rubber. A granular composite can form a granular bulge capable of increasing a friction coefficient when being used, and the particles in the granular composite are mutually wound, so that the force is effectively relieved, and the wear resistance and antiskid property of the material are improved; and meanwhile, an internal stress generated by friction is dispersed by mutual winding of the granular aggregates, so that the problems of antiskid surface wear and friction coefficient reduction on the surface of the rubber material are reduced, the durability level of the antiskid property of the material is effectively improved, and the antiskid property of the material is further improved.

Description

Technical field [0001] The invention relates to a method for preparing a non-slip tread rubber material, and belongs to the technical field of rubber materials. Background technique [0002] With the rapid development of the automobile industry and the increasing improvement of people’s living standards, as well as the country’s advocacy for fuel-saving and environmental protection [0003] People have higher and higher performance requirements for passenger cars, including comfort, safety and fuel-saving performance. In recent decades, there have been more and more researches on the performance of high-performance tires at home and abroad. The focus of the research is mainly on rolling loss, wet skid resistance and wear resistance, especially wet skid resistance. These three performances are also called the three driving performances of car tires. Especially after the industrialization of green tires with in-situ modified silica with silane coupling agent as the filler and solut...
