Problems solved by technology

However, there are residual double bonds in the chloroprene rubber molecule, which causes its heat resistance to be inferior to that of saturated rubber such as ethylene-propylene rubber. When used in some harsh and harsh environments, there are problems with poor heat resistance and aging resistance, which limits its application

Description

technical field [0001] The invention relates to the technical field of neoprene rubber, in particular to a heat-resistant and aging-resistant neoprene pipe material. Background technique [0002] Neoprene is a synthetic rubber produced by α-polymerization of chloroprene. It has the characteristics of high elasticity and solvent resistance. It also has excellent properties such as weather resistance, flame resistance, ozone resistance, and heat resistance. It has been widely used in Manufactures auto parts and adhesives. In recent years, the demand for neoprene has been increasing for industrial products and automotive parts, and the requirements for its performance are also increasing. However, there are residual double bonds in the chloroprene rubber molecule, which causes its heat resistance to be inferior to that of saturated rubber such as ethylene-propylene rubber. When used in some harsh and harsh environments, there are problems with poor heat resistance and aging re...
