A kind of rubber for bushing with self-lubricating effect and preparation method thereof

Abstract

The invention discloses rubber with a self-lubricating effect for a lining. The rubber is prepared from the following components in percentage by weight: 55 to 59 percent of natural rubber, 7 to 14 percent of butadiene rubber, 0.7 to 2 percent of refined vegetable oil oleamide, 0.7 to 2 percent of molybdenum disulfide, 0.7 to 2 percent of carbon nano tubes, 3.5 to 4.1 percent of graphite, 3.2 to 3.5 percent of zinc oxide, 1 percent of stearic acid, 1 to 1.7 percent of antioxidant 6PPD, 1 percent of antioxidant TMQ, 2 percent of microcrystalline wax, 13.1 to 13.8 percent of carbon black N 330, 1.3 to 1.4 percent of sulfur grundum and 1.0 to 1.3 percent of accelerant CZ. The rubber for the lining, disclosed by the invention, has quadruple sustained releasing functions and is suitable for the lining of a self-lubricating high-end car; the problem that common self-lubricating rubber easily fails in lubricating can be solved, and the abrasion resistance of the rubber is increased; by combining specific situations of rubber abrasion at different stages, the service life of rubber and lining products can be prolonged. Meanwhile, the invention provides a preparation method of the rubber with the self-lubricating effect for the lining.

Description

technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to a rubber for bushing with self-lubricating effect and a preparation method thereof. Background technique [0002] The good damping and shock absorption of rubber materials can make the shock-absorbing bushing products obtain excellent NVH performance; while the rubber and the metal frame of the bushing are combined, the high elasticity of the rubber itself can also be used to avoid the metal frame of the bushing and the vehicle. The friction of the frame metal plays the role of cushioning, protection and noise reduction. However, while rubber products play the role of cushioning and protection, they will also cause wear and tear due to friction, and some rubber products cannot be lubricated manually with various polar greases due to the assembly position of some rubber products and the characteristics of rubber. . Therefore, just need to design a kind of rubber formu...

AI Technical Summary

Problems solved by technology

However, due to the traditional self-lubricating rubber formula, only a single lubricant that can be precipitated on the rubber surface is used. When the rubber friction wears out the lubricant, the rubber raw material will be directly worn, causing the rubber parts to fail.
