Abstract

The invention discloses a rubber sheath rubber matrix, relating to the technical field of sealing materials. The rubber sheath rubber matrix is prepared from the following raw materials in parts by weight: 30-40 parts of silicon rubber, 25-40 parts of epichlorohydrin rubber, 5-13 parts of stearic acid, 10-15 parts of paraffin oil, 1-6 parts of nano titanium dioxide, 3-12 parts of anti-aging agent, 1-10 parts of accelerator, 2-9 parts of di-n-octyl phthalate and 5-10 parts of carbon black. The rubber sheath rubber matrix uses the silicon rubber and epichlorohydrin rubber as the base raw materials and uses the stearic acid, paraffin oil, nano titanium dioxide, anti-aging agent and other assistants as the auxiliary materials; and the rubber sheath rubber matrix product has the advantages of low production cost, favorable elasticity, favorable aging resistance, favorable oil resistance, favorable bonding property and longer service life.

Description

technical field [0001] The invention relates to the technical field of sealing materials, in particular to a rubber sheath compound. Background technique [0002] The rubber sheath is suitable for hydraulic hoses, electronic devices, moving mechanisms or auto parts, etc., to protect the internal products, not only improve the aesthetics and restraint, but also prolong the life of the internal products. Therefore, rubber sheaths are widely used in electrical appliances, medicine, chemicals, food, automobiles, machinery and other industries. However, due to raw materials, manufacturing processes or human factors, most of the rubber sheaths on the market are often aging, deformed and damaged. Contents of the invention [0003] The purpose of the present invention is to provide a rubber sheath rubber compound, which can solve the problems of easy aging, deformation and damage of the existing rubber sheath. [0004] In order to solve the above problems, the technical solution...
