Abstract

The invention discloses an anticorrosive rubber material composed of the raw materials of, by weight, 0.2-0.6 parts of 8-10% sulfuric acid, 26-30 parts of melamine, 5-8 parts of a 37% formaldehyde solution, 7-10 parts of urea, 6-10 parts of microcrystalline cellulose, 1-1.2 parts of isopropanol, 2-3 parts of sulfur, 3-4 parts of maleic anhydride, 210-230 parts of neoprene S40V, 4-6 parts of methylparaben, 0.6-1 parts of triterpenoid saponin, 2-4 parts of calcium propionate, 2-3 parts of sodium diacetate, 1-3 parts of N-methylpyrrolidone, 4-5 parts of nano-grade calcium phosphate, 0.8-1 part of sodium sorbate, 40-54 parts of fluorapatite, and 2-4 parts of an anti-aging agent RD. according to the invention, with the crosslinking effect of maleic anhydride, microcrystalline cellulose forms a closer network structure in melamine resin formed by melamine, urea and formaldehyde, such that resin viscosity and tensile deformation resistance are well improved, and certain reinforcement and tackification effects are performed in the rubber material. Rubber flexure cracking resistance, hot air aging resistance and stability are improved. With the added anticorrosive dispersion liquid, the anticorrosive property of the rubber product can be effectively improved, and the service life of the rubber material can be prolonged.

Description

technical field [0001] The invention mainly relates to the field of rubber, in particular to an anti-corrosion rubber material. Background technique [0002] Chloroprene rubber is made of chloroprene as the main raw material through homopolymerization or copolymerization of a small amount of other monomers. Such as high tensile strength, excellent heat resistance, light resistance, aging resistance, and oil resistance are superior to natural rubber, styrene-butadiene rubber, and butadiene rubber. It has strong flame resistance and excellent flame retardancy resistance, high chemical stability and good water resistance. The disadvantage of chloroprene rubber is that it has poor electrical insulation performance and cold resistance, and the raw rubber is unstable during storage. Neoprene is widely used, such as used to make conveyor belts and transmission belts, sheathing materials for wires and cables, to make oil-resistant hoses, gaskets, and chemical-resistant equipme...
