High-temperature-resistant wear-resistant anti-aging rubber material and preparation method thereof

Abstract

The invention provides a high-temperature-resistant wear-resistant anti-aging rubber material and a preparation method thereof, and relates to the technical field of rubber materials. The rubber material is prepared from the following raw materials, in parts by weight: 30-60 parts of silicone rubber, 10-20 parts of fluorine rubber, 5-15 parts of fluorosilicone rubber, 5-10 parts of stearic acid, 4-8 parts of magnesium hydroxide, 3-5 parts of tert-butyl peroxybenzoate, 1-2 parts of tetraethylthiuram disulfide, 3-5 parts of zinc oxide, 0.1-0.5 part of N-(cyclohexylthio)phthalimide, 3-5 parts ofliquid paraffin, 5-7 parts of di-tert-butyl-p-cresol, 4-6 parts of triethylene glycol di-2-ethylhexoate, 2-5 parts of dibutyltin dilaurate, 5-15 parts of chlorinated paraffin, 5-10 parts of sulfur, 15-20 parts of a filler, 5-10 parts of sepiolite fibers, 3-5 parts of copper powder, 3-8 parts of polytetrafluoroethylene, 0.5-0.9 part of an anti-aging agent, and 3-5 parts of a bacteriostatic agent. The preparation method of the high-temperature-resistant wear-resistant anti-aging rubber material includes the four steps of internal mixing, mixing, vulcanization, and injection molding. The rubber material provided by the invention has the characteristics of high-temperature resistance, wear resistance and aging resistance, and has the bacteriostatic and flame-retardant functions.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a high-temperature-resistant, wear-resistant and aging-resistant rubber material and a preparation method thereof. Background technique [0002] At present, rubber products are used in all aspects of social life, such as various rubber production equipment or rubber parts in heavy industries such as mining, transportation, construction, machinery, electronics, and emerging industries. However, when ordinary rubber materials encounter working environments with acid-base or salt solutions, they are often corroded due to frequent contact with chemicals such as acid-base or salt, resulting in rubber swelling, rubber molecule breakage, and depolymerization, which in turn increases its mechanical strength. And physical properties are significantly reduced, or even completely lose their due effect, which will directly affect production safety and personal safety, and cannot mee...
