Abstract

The invention relates to a rubber tube, belonging to the technical field of chemical industry and particularly the technical field of rubber formulae. The invention is characterized in that the rubber tube is prepared from the following raw materials in parts by weight: 80-120 parts of nitrile-butadiene rubber, 70-90 parts of carbon black, 1.5-2.5 parts of zinc stearate, 5-7 parts of anti-aging agent NAUGARD, 20-30 parts of plasticizer TP-95, 0.3-0.5 part of sulfur S-80, 3-10 parts of high aromatic oil, 4-6 parts of indirect-process zinc oxide, 0.2-0.4 part of anti-scorching agent, 10-15 parts of silicon dioxide, and dehydrated liquid composition with quaternary ammonium salt structure and carboxyl ion compound.

Description

technical field [0001] The invention relates to a rubber pipe fitting, which belongs to the technical field of chemical industry, and in particular relates to the technical field of rubber formulation. Background technique [0002] Rubber: 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] The word rubber comes from the Indian word cau-uchu, which means "tearful tree". Natural rubber is made by coagulating and drying the latex that flows out from Hevea clover tree tapping. In 1770, British chemist J. Priestley discovered that rubber can be used to erase pencil writing. At that time, the material for this purpose was calle...
