Abstract

The invention discloses anti-bacterial oil-extended butadiene rubber used for a high pressure oil pipe of a hydraulic breaking hammer. The butadiene rubber is prepared from, by weight, 20-22 parts of carbon nanotubes, 6200-6400 parts of butadiene, a proper amount of hydrogenated gasoline, 0.18-0.19 parts of nickel naphthenate, 1.8-1.9 parts of triisobutyl aluminum, 2.1-2.3 parts of boron trifluoride diethyl ether, 1.7-1.9 parts of octyl aldehyde, 3400-3600 parts of high aromatic oil, 3-4 parts of tetrabutyl titanate, 150-170 parts of ethanol, 24-26 parts of ammonia water, 15-17 parts of water, 4-5 parts of polyarylene ether nitrile, 1.2-1.5 parts of coptisine, 3-4 parts of EVA, and 3-4 parts of trifluoroethyl acrylate. By means of the coptisine, antibacterial property of the rubber is improved and mildewing is prevented. By means of the polyarylene ether nitrile and EVA, toughness and acid and alkali resistance of the rubber are improved.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to oil-filled butadiene rubber for antibacterial hydraulic breaker high-pressure oil pipes and a preparation method thereof. Background technique [0002] "Development and Production of New Oil-Extended Butadiene Rubber" briefly introduces the development history, types, characteristics, polymerization reaction mechanism, industrial production and application of synthetic rubber technology at home and abroad. In this paper, a new type of oil-extended butadiene rubber product is researched and developed, and the catalyst formula and polymerization rate are changed by the regulator method to synthesize a high Mooney viscosity base rubber; and then an appropriate oil-extended process is selected to produce oil-extended butadiene rubber. Oil-extended cis-butadiene rubber was prepared by solution polymerization in 5L and 50L kettles with cis-1,3-butadiene as the monomer and nick...
