Abstract

The invention discloses a nano carbon rubber material which is prepared from the following raw materials in parts by weight: 0.5 to 1 part of potassium citrate, 0.2 to 0.6 parts of 8 to 10 percent sulfuric acid, 26 to 30 parts of melamine, 5 to 8 parts of 37 percent formaldehyde solution, 7 to 10 parts of urea, 6 to 10 parts of microcrystalline cellulose, 1 to 1.2 parts of isopropanol, 2 to 3 parts of sulfur, 3 to 4 parts of maleic anhydride, 3 to 4 parts of molybdenum boride, 210 to 230 parts of chloroprene rubber S40V, 2 to 3 parts of aluminium potassium sulfate, 2 to 3 parts of phosphate, 6 to 10 parts of dioctyl phthalate, 0.4 to 1 part of nonylphenol polyoxyethylene ether, 40 to 43 parts of nano carbon powder, 2 to 3 parts of a promoting agent CA and 3 to 4 parts of an anti-aging agent TNP. Under the crosslinking action of maleic anhydride, a closer network structure is formed by microcrystalline cellulose in melamine resin formed by melamine, urea and formaldehyde, so that the viscosity and the tensile deformation resistance of the resin are well improved; certain reinforcement and viscosity increase effects are achieved in a rubber material, and the deflection, cracking, hot air aging resistance performances and the stability are improved.

Description

technical field [0001] The invention mainly relates to the field of rubber, in particular to a nanometer carbon 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 equipm...
