Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an oxygen-resistant and shock-resistant synthetic rubber production method, which solves the phenomenon that most of the synthetic rubbers are oxidized with air during use, causing the rubber to break and rot , during the use of rubber, it is easy to be worn and has poor shock absorption performance, so it cannot be widely used.

Abstract

The invention discloses an oxygen-resistant shock-resistant synthetic rubber preparation method. Oxygen-resistant shock-resistant synthetic rubber consists of rubber, zinc oxide, sulfur, stearic acid,an accelerant DM, a white filler, a softening agent, an accelerant TMTD (Tetramethylthiuram Disulfide) and carbon black. By adopting the oxygen-resistant shock-resistant synthetic rubber preparationmethod, under the action of the zinc oxide, the synthetic rubber has good corrosion resistance, tearing resistance and elasticity, and the consequence that the synthetic rubber has cracks and the stability of the synthetic rubber is affected since the synthetic rubber is reacted with irritant gases in the air when being used; due to reactions of the synthetic rubber after desulfuration, the synthetic rubber has shock resistance and durability, and the consequence that damage of the synthetic rubber is accelerated since the synthetic rubber is aged and abraded in the use process can be avoided;due to stirring and mixing of a polymerization kettle, raw materials can be sufficiently stirred, and the consequence that the use of the synthetic rubber is affected because of insufficient stirringcan be avoided.

Description

technical field [0001] The invention relates to the technical field of industrial production, in particular to an oxygen-resistant and shock-resistant synthetic rubber production method. Background technique [0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer. Its glass transition temperature is low and its molecular weight is often large, greater than hundreds of thousands. Early rubber was obtained from latex of plants such as rubber trees and rubber grasses. After processing, it is elastic and insulating. Durable, water and air impermeable material. High elastic polymer compound. Divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and othe...
