Abstract
The invention discloses a high-abrasion-resistance rubber sealing piece. The high-abrasion-resistance rubber sealing piece comprises, by weight, 154-175 parts of rubber polymer, 20-30 parts of a reinforcing agent, 2-3 parts of antiager, 2-3 parts of a vulcanization accelerator, 10-15 parts of plasticizer and 5-8 parts of nano calcium carbonate. Compared with the prior art, the high-abrasion-resistance rubber sealing piece has good chemical stability and high mechanical strength, is resistant to abrasion, the high temperature and aging and can resist the temperature of 400 DEG C or above, and the service life of the rubber sealing piece is greatly prolonged. Meanwhile, carbon black is selected for strengthening silicone rubber, enough elasticity and tensile strength are guaranteed, and meanwhile abrasion resistance is enhanced again.
Description
Technical field
The present invention relates to seal production field, particularly a kind of high wearable rubber seal.
Background technology
Glue seal is the class general basic element rubber seal in sealing device extensively to be applied in Sealing Technology
A class rubber.As which has elastic modelling quantity very little, elongation is high, the advantage of resistance to gas permeability and be widely used in
In various plant equipment.It is due to containing soda acid composition in the lubricating system of plant equipment, readily permeable in seal,
So as to play the expansion of seal, the service life of seal is have impact on.
The most of rubber seals for now using, anti-wear performance are relatively poor, and heat resistance is also less fully up to expectations, by
In the severe of use environment, heat produced if any high temperature, friction and friction etc. affects, the service life of rubber seal and
Spoilage is remained high always.
