Description
Technical field
The present invention relates to rubber manufacturing field more particularly to a kind of bibasic ethylene propylene rubber O-rings that high temperature performance is excellent.
Background technique
At present in production equipment, it is very common for being sealed using O-ring to equipment, and equipment is needed due to using
Ask, can be used in the environment of high temperature perhaps low temperature and General Purpose Rubber made of O-ring make in the case where high temperature or low temperature
Used time, service life are influenced by temperature, it is easy to be damaged.Therefore, General Purpose Rubber is solved in high temperature or low temperature environment
The problem of being easily damaged just is particularly important.
Summary of the invention
In view of the above-mentioned problems of the prior art, the object of the present invention is to provide a kind of binary that high temperature performance is excellent
EP rubbers O-ring, by bibasic ethylene propylene rubber, carbon black, paraffin oil, nanoclay, zinc oxide, stearic acid and vulcanizing agent etc.
Prepared by raw material, produce a kind of bibasic ethylene propylene rubber O-ring that high temperature performance is excellent, improve rubber cold resistance and
Heat resistance solves the problems, such as that General Purpose Rubber is easily damaged in high temperature or low temperature environment.
The present invention provides a kind of bibasic ethylene propylene rubber O-ring that high temperature performance is excellent, the bibasic ethylene propylene rubber O-ring
It is made of bibasic ethylene propylene rubber, carbon black, paraffin oil, nanoclay, zinc oxide, stearic acid and vulcanizing agent, third rubber of binary second
The composition mass fraction of glue O-ring is 90 ~ 130 parts of bibasic ethylene propylene rubber, 50 ~ 100 parts of carbon black, paraffin oil 5 ~ 25 part, nanometer pottery
15 ~ 45 parts of soil, 5 ~ 15 parts of zinc oxide, 1 ~ 5 part and 2 ~ 8 parts of vulcanizing agent of stearic acid.
Further improvement lies in that: the carbon black selects carbon black N550.
Further improvement lies in that: the vulcanizing agent is peroxide vulcanizing agent.
Further improvement lies in that: the bibasic ethylene propylene rubber is the bibasic ethylene propylene rubber after long chain branching.
The beneficial effects of the present invention are: by bibasic ethylene propylene rubber, carbon black, paraffin oil, nanoclay, zinc oxide, hard
Prepared by the raw material such as resin acid and vulcanizing agent, produce a kind of bibasic ethylene propylene rubber O-ring that high temperature performance is excellent, is improved
The cold resistance and heat resistance of rubber, O-ring made from the formula, can be used for a long time at -55 DEG C, and cryogenic property is outstanding, use
The bibasic ethylene propylene rubber of long chain branching improves product high temperature resistance using peroxide cure, can be under 150 DEG C of environment
It is used for a long time, extends product service life.
