Problems solved by technology

The acid absorbing agent for preparing chlorosulfonated polyethylene rubber in the prior art is magnesium oxide or lead monoxide, and the temperature resistance of the chlorosulfonated polyethylene rubber material prepared by using magnesium oxide The temperature resistance of chlorosulfonated polyethylene rubber material prepared by acid agent can reach 150°C. Since lead monoxide contains the harmful substance "lead" banned in the ELV directive, there are problems of toxicity, harmfulness, environmental protection and non-compliance with the requirements of the ELV directive

Abstract

The invention discloses a preparation method of environmental protection chlorosulfonated polyethylene rubber, comprising the formula and preparation technique. The invention uses the environmental protection magaldrate carbonate hydrate for replacing the lead monoxide acid-acceptor and uses the mated formula and the preparation technique, thereby preventing the defects of the lead monoxide acid-acceptor in the prior technique that the lead monoxide acid-acceptor is toxic, harmful, not environmental friendly and not coincident with the ELV command requirement. The anti-medium, anti-temperature rubber products produced by the environmental protection chlorosulfonated polyethylene rubber material has features of innocuity, environmental protection, coincidence with the ELV command requirement, in the premise of satisfying various mechanical strength, physicochemical index and 150 DEG C resistance requirement.

Description

technical field [0001] The invention relates to the preparation of a medium-resistant and temperature-resistant rubber, specifically an environmentally-friendly chlorine-sulfonated polyethylene rubber material prepared by an environmentally-friendly acid-absorbing agent, which is used to manufacture rubber products such as automobile rubber hoses. Preparation technology of sulfonated polyethylene rubber. Background technique [0002] Chlorosulfonated polyethylene rubber materials are widely used in the manufacture of rubber products such as power steering tubes, acid and alkali resistant rubber tubes, and require a temperature resistance of up to 150°C. The acid absorbing agent for preparing chlorosulfonated polyethylene rubber in the prior art is magnesium oxide or lead monoxide, and the temperature resistance of the chlorosulfonated polyethylene rubber material prepared by using magnesium oxide The temperature resistance of chlorosulfonated polyethylene rubber material pr...
