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 crush-resisting and high-temperature-resisting rubber material for transformer sealing rings. The crush-resisting and high-temperature-resisting rubber material comprises, by weight, 70-90 parts of nitrile rubber, 20-40 parts of fluororubber, 60-80 parts of white carbon black, 2-4 parts of zinc oxide, 0.3-0.5 part of triethylenetetramine, 1.5-2.5 parts of sulphur S80, 1.5-2.5 parts of antiagers MB, 0.3-0.5 part of accelerant TMTD, 2-4 parts of methyl trimethoxy silane, 0.3-0.5 part of olein, 0.5-1 part of maleic rosin, 0.5-1 part of tetrabutyl titanate, 0.15-0.25 part of titanate coupling agent NDZ-401, 6-8 parts of nano-graphite powder and 4-6 parts of castor oil. The crush-resisting and high-temperature-resisting rubber material has the advantages of good wear resistance, long-lasting antifriction performance, good crush and high temperature resistance performance, long service life, good sealing performance and applicability to transformer sealing ring materials.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a rubber material for a pressure-resistant and high-temperature resistant transformer 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 mo...
