Abstract

The invention provides an automobile hub bearing seal ring and a manufacturing technique thereof, belonging to the technical field of automobile accessories. The automobile hub bearing seal ring solves the technical problems of incapability of bearing higher temperature, poor high temperature resistance, no manufacturing technique and the like in the existing seal ring. The automobile hub bearing seal ring is prepared from the following components in percentage by mass: 70-80% of nitrile-butadiene rubber, 10-20% of sulfur, 1-3% of anti-aging agent 4010, 0.5-0.8% of zinc oxide, 2-4% of stearic acid, 1-5% of calcium hydroxide, 0.2-0.6% of alumina powder, 0.1-0.3% of dibutyl phthalate, 3-7% of silicon dioxide and 1-4% of diatomite, totaling 100%. The invention also provides a manufacturing technique of the automobile hub bearing seal ring. The automobile hub bearing seal ring has the advantages of favorable high temperature resistance and high production efficiency.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to an auto wheel hub bearing sealing ring and a manufacturing process thereof. Background technique [0002] Rubber is the latex taken from plants such as rubber trees and rubber grasses. After processing, it is a material with elasticity, insulation, and impermeability to water and air. High elastic polymer compound. Divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. Rubber products have unique properties, so rubber is a good raw material for making sealing rings. Automobile hub bearing sealing ring is used on the hub bearing of the automobile, which plays the role of sealing and dustproof. [0003] After searching, for example, Chinese patent literature discloses a sealing ring for automobile bearings [...
