Problems solved by technology

[0002] In recent years, the driving speed of agricultural locomotives has been greatly increased, and overloading is common. Tires are increasingly unable to adapt to high-speed and overloading conditions. The service temperature of tires continues to rise, the tire surface is damaged or even loses its original performance, and as the temperature of the tire service environment rises, the rubber ages, and it is easy to release toxic and corrosive gases. , environmental protection and long-term stable operation put forward higher requirements. How to prepare a rubber material for agricultural locomotive tires with good high temperature resistance, environmental protection, wear resistance, and good tensile strength and tear strength has become a problem that needs to be solved at present. technical problem
