Abstract
The present invention relates to a kind of anti-aging rubber gaskets, the component of the anti-aging rubber gasket is as follows according to parts by weight: 15-25 parts of nitrile rubber, 15-20 parts of methyl vinyl silicone rubber, 20-25 parts of polycaprolactone, 5-10 parts of silicon powder, 3-7 parts of carbon black, 2-5 parts of basalt fibre, 1-2 parts of age resister, poly- aryl phosphate ester 0.5-1.5 parts, 0.5-1.5 parts of antioxidant, 1-3 parts of vulcanization accelerator.Cost of manufacture of the present invention is cheap, and antiageing effect is good, can effectively extend the service life of rubber gasket, improve the sealing performance of gasket, have broad application prospects.
Description
Technical field
The present invention relates to rubber gasket technical field more particularly to a kind of anti-aging rubber gaskets.
Background technique
Rubber gasket is a kind of self-expansion sealing pad, belongs to seal for pipe joints component.Rubber sheet gasket has oil resistant, acidproof
The performances such as alkali, resistance to fever and chills, ageing-resistant, are therefore widely used in the industries such as automobile, electronics, chemical industry, antistatic, fire-retardant, food.
Although current rubber gasket can satisfy most of demand produced and live, in the environment of high temperature
In, rubber gasket easily aging, and easily deformation is so that the sealing performance of rubber gasket sharply declines, thus pole
The earth reduces the sealing performance of rubber gasket.
Summary of the invention
To solve the above problems, the present invention provides a kind of anti-aging rubber gaskets.
Technical scheme is as follows:
A kind of anti-aging rubber gasket, it is characterised in that: the component of the anti-aging rubber gasket is according to parts by weight
It is as follows: 15-25 parts of nitrile rubber, 15-20 parts of methyl vinyl silicone rubber, 20-25 parts of polycaprolactone, silicon powder 5-10
Part, 3-7 parts of carbon black, 2-5 parts of basalt fibre, 1-2 parts of age resister, poly- aryl phosphate ester 0.5-1.5 parts, antioxidant 0.5-
1.5 parts, 1-3 parts of vulcanization accelerator.
Further, the age resister is one of thiobis methylphenol and the double octadecyls of thio-2 acid.
Further, the antioxidant is one of diphenylamines, p-phenylenediamine.
Further, the vulcanization accelerator is one of ethylene thiourea, thiazole.
According to the above aspect of the present invention, the present invention at least has the advantages that
Cost of manufacture of the present invention is cheap, and antiageing effect is good, can effectively extend the service life of rubber gasket, improves
The sealing performance of gasket, has broad application prospects.

5 parts of military rock fiber, 1 part of thiobis methylphenol, 0.8 part of poly- aryl phosphate ester, 1.25 parts of p-phenylenediamine, 3 parts of ethylene thiourea.
Embodiment 2
A kind of anti-aging rubber gasket, it is characterised in that: the component of the anti-aging rubber gasket is according to parts by weight
It is as follows: 21 parts of nitrile rubber, 18 parts of methyl vinyl silicone rubber, 23 parts of polycaprolactone, 6 parts of silicon powder, 5 parts of carbon black, profound
4 parts of military rock fiber, double 1.5 parts of the octadecyls of thio-2 acid, 0.9 part of poly- aryl phosphate ester, 1.5 parts of diphenylamines, 2 parts of thiazole.
The above is only a preferred embodiment of the present invention, it is not intended to restrict the invention, it is noted that for this skill
For the those of ordinary skill in art field, without departing from the technical principles of the invention, can also make it is several improvement and
Modification, these improvements and modifications also should be regarded as protection scope of the present invention.
