Environmentally-friendly rubber and preparation method thereof

Abstract

The invention relates to environmentally-friendly rubber and a preparation method thereof. The environmentally-friendly rubber is prepared from the following raw materials in parts by weight: 5 to 15parts of natural rubber, 1 to 3 parts of butadiene styrene rubber, 1 to 5 parts of high styrene rubber, 1.5 to 4 parts of white carbon black, 0.1 to 0.4 part of sulfur, 0.1 to 0.3 part of hard aceticacid, 0.3 to 0.6 part of zinc oxide, 0.13 to 0.27 part of an accelerator, 0.3 to 0.9 part of an anti-aging agent, 0.11 to 0.17 part of phthalocyanine blue, 0.02 to 0.06 part of ultramarine, 0.002 to 0.006 part of carbon black, 0.01 to 0.04 part of ethylene glycol and 0.1 to 0.5 part of titanium dioxide. The environmentally-friendly rubber prepared through the preparation method disclosed by the invention is relatively high in heat resistance and heat stability and long in service life; by the adding of the phthalocyanine blue and the ultramarine, vulcanized rubber has a bright color and an attractive appearance.

Description

technical field [0001] The rubber of the invention belongs to the technical field of chemical industry, and in particular relates to the technical field of formulation of environment-friendly rubber and a preparation method thereof. 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 (Tg) is low, and its molecular weight is often large, greater than hundreds of thousands. [0003] Because rubber is a poor thermal conductor, rubber is usually treated by vulcanization, and bright rubber products will fade due to high temperature vulcanization, and the raw materials of rubber products are rich in bicyclobenzene, which is easy to cause cancer and cause environmental pollution. Therefore, ...

Problems solved by technology

[0003] Because rubber is a poor thermal conductor, rubber is usually treated by vulcanization, and bright rubber products will fade due to high temperature vulcanization, and the raw materials of rubber products are rich in bicyclobenzene, which is easy to cause cancer and cause environmental pollution. Therefore, There is a need for a rubber material that not only has the performance of bright color after vulcanization, but also reduces the toxic and harmful substances in the rubber material and reduces the harm to the environment
