Abstract
A preparation method of a high-corrosion-resistant novel rubber sealing material includes following steps: (a) adding high-corrosion-resistant 4,4'-bis([alpha],[alpha]-dimethylbenzyl)diphenylamine as an anti-oxidant to an anti-aging agent stearate and performing mixing; (b) adding carbon black, calcium carbonate, polyethylene glycol and polyethylene wax and performing internal-mixing; (c) adding zinc dimethyldithiocarbamate, a vulcanizing agent sulfur, and a flame retardant ammonium polyphosphate, and performing open milling at 55-70 DEG C until fracture surfaces are uniform; and (d) performing vulcanization on a vulcanizing machine at 170-185 DEG C for 8-10 min to obtain the rubber sealing material. Because the anti-oxidant 4,4'-bis([alpha],[alpha]-dimethylbenzyl)diphenylamine is high in corrosion resistance and is suitable for various environments corroding rubber materials, the novel rubber sealing material added with the 4,4'-bis([alpha],[alpha]-dimethylbenzyl)diphenylamine is greatly enhanced in corrosion resistance.
