Problems solved by technology

However, the hardness of graphite is low and it is easy to wear and tear. Only using graphite as a lubricating component is not conducive to maintaining long-term lubrication and anti-friction performance, and the effect of prolonging the service life of rubber products is limited. It is necessary to improve it

Abstract

The invention discloses a flame-retarding antistatic rubber material used in a bearing sealing ring and a preparation method thereof. The rubber material is prepared from, by weight, 100-120 parts of nitrile butadiene rubber, 40-60 parts of white carbon black, 20-30 parts of electric-conductive mica powder, 2-4 parts of zinc oxide, 1.5-2.5 parts of sulfur S80, 1.5-2.5 parts of an anti-aging agent MB, 0.3-0.5 parts of an accelerant TMTD, 2-4 parts of methyltrimethoxysilane, 0.5-1 part of triethanolamine borate, 3-5 parts of triphenyl phosphite, 0.5-1 part of tetrabutyl titanate, 0.15-0.25 parts of a titanate coupling agent NDZ-401, 6-8 parts of nano graphite powder, 4-6 parts of castor oil, and 0.5-1 part of oleamide. The rubber material has good wear resistance and durable friction reduction performance, has excellent anti-static and flame-retarding performance, is long in service life and has good sealability, and is suitable for being used for a bearing sealing ring.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a rubber material for a flame-retardant antistatic bearing sealing ring and a preparation method thereof. Background technique [0002] As an indispensable and important polymer material in the national economy and daily life, rubber has excellent physical and mechanical properties, elasticity and processing properties, and plays an irreplaceable role in many important fields such as automobile transportation, mining, and chemical industry. . Tribological performance is a very important indicator of rubber materials, related to the wear resistance of rubber tire products, the wear resistance of seals, etc. Improving the wear resistance of rubber materials is conducive to increasing its service life, and can bring considerable economic and social benefits in terms of saving energy, materials, lubricants, etc. [0003] At present, one of the more effective methods to imp...
