Rubber material

Abstract

The invention discloses a rubber material. The rubber material is prepared from, by weight, 42-70 parts of ethylene propylene rubber, 65-82 parts of aluminum oxide, 55-90 parts of titanium dioxide, 35-67 parts of graphite, 50-65 parts of carbon fibers, 1-3 parts of vegetable oil and 3-5 parts of resin. The rubber material has remarkable high-temperature resistance, low-temperature resistance, high-voltage resistance, ozone aging resistance, radiation resistance, high gas permeability and solvent resistance.

Description

technical field [0001] The invention specifically relates to a rubber material. Background technique [0002] Rubber is 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 (T g) is low, and its molecular weight is often large, greater than hundreds of thousands. [0003] Natural rubber is produced from latex, and some of the non-rubber components contained in the latex remain in the solid natural rubber. Generally, natural rubber contains 92%-95% rubber hydrocarbons, while non-rubber hydrocarbons account for 5%-8%. Due to different production methods, different production areas and even different rubber harvesting seasons, the proportions of these ingredients may vary, but they are basically within the range.

Problems solved by technology

The moisture in the dry rubber does not exceed 1%, and it can be volatilized during processing. However, if the moisture content is too high, it will not only make the raw rubber easy to mold during storage, but also affect the processing of rubber. Agglomerates; bubbles are easily generated during calendering and extrusion, and bubbles or spongy are generated during vulcanization.
