Abstract

The invention discloses a preparation process for magnetic chlorinated rubber, relating to the technical field of rubber processing. The process comprises the following steps of 1) raw material preparation; 2) sizing material plastication; 3) magnetic oriented mixing; 4) sizing material molding and magnetizing; and 5) sizing material vulcanization. The magnetic chlorinated rubber prepared by using the preparation process has good fire resistance, high strength, excellent mechanical property and good abrasive resistance, can be adapted to rubbing for a long time, can not be damaged, and has high magnetic property and good elasticity; an environment-friendly fire retardant is added in the mixing process, so that the flame retardant property is further improved; plenty of energy sources can be saved in the production process, and the preparation process is simple and is easy to master.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a manufacturing process of magnetic chlorinated rubber. Background technique [0002] Rubber is an irreplaceable high-elastic polymer material. With the increasing shortage of petroleum resources, the research on green rubber products made of renewable resources has become a current research hotspot. Natural rubber is a highly elastic material collected from natural plants and processed. It is a natural polymer compound with polyisoprene as the main component. Because of its excellent comprehensive performance and processing performance, it is Widely used in industrial production and scientific research. In order to further improve the physical and mechanical properties of natural rubber and reduce its industrial cost, various composite rubber products have appeared one after another. [0003] Chlorinated rubber is an important rubber derivative in industry. It is wi...
