Problems solved by technology

[0002] With the enhancement of people's awareness of environmental protection, the safety and environmental protection requirements for the rubber materials used are getting higher and higher. At present, most of the chlorohydrin rubber materials commonly used in China are lead-containing metal oxides. Although the use of lead-containing metal oxides can It has a good degree of cross-linking so as to obtain good heat aging resistance. However, lead metal oxides are volatilized in a hot environment for a long time, which will seriously endanger people's lives. Moreover, the resistance of chlorohydrin rubber materials Therefore, it is extremely important to develop a rubber material that meets environmental protection requirements and is heat-resistant and wear-resistant.
