AI Technical Summary

Technical Problem

Existing carbon black rubber composite materials have poor wear resistance and flexural fatigue resistance, making it difficult to meet the requirements of low fuel consumption and low carbon emissions for tires.

Method used

Carbon black rubber composites are prepared by using a combination of multifunctional natural rubber and modified carbon black, and reinforcing materials such as modified attapulgite, through mixing and high-temperature vulcanization. This forms a multi-component cross-linked network, which improves the resistance to molecular chain movement and dispersibility.

Benefits of technology

It significantly improves the wear resistance and flexural fatigue resistance of carbon black rubber composites, and enhances the mechanical properties and fatigue damage resistance of the materials.
