Description
Technical field
The present invention relates to a kind of rubber composition, and in particular to a kind of resistant to elevated temperatures rubber composition.
Background technology
Rubber industry is one of important foundation industry of national economy.It is indispensable that it not only provides daily life for people
The light industry rubber product such as daily, medical, and carried to the heavy industry such as digging, traffic, building, machinery, electronics and new industry
For various rubber system production equipments or rubber components.
Rubber industry is got up with automobile industry development.Sixties auto industry is sent out at a high speed with petro chemical industry
Exhibition, makes the rubber industry level of production be greatly improved.Into the seventies, to adapt to high speed, safety and the saving of automobile
The energy, eliminates pollution, the need for preventing in terms of public hazards, and promote tire new varieties constantly goes out sight, and raw material gum consumption is being handed over
Occupy sizable proportion in terms of logical transport.That just more, kind of big and small rubber required for industrial department
Many, purposes is wide, and what is had also has particular/special requirement.The development of agriculture, forestry, water conservancy cause, it is also desirable to various rubbers, except dilatory
Machine and agricultural machinery with outside various tires, united reaper need to rubber belt track, the rubber that irrigation water pond, reservoir are used
Impervious barrier and part for rubber dam, the consumption such as rubber ship, life-saving are all increasing, agricultural byproducts processing equipment and woods, herd, fishery
In terms of technical equipment, there is rubber accessory.Rubber or important strategic materials, apply even more ten in military and national defense simultaneously
Divide extensive.
Rubber is used under environment complicated and changeable, requires that rubber has specifically according to different use environments
Function, requires rubber to have excellent high temperature steam performance in the high temperature steam environments such as the steam injection in oil field.At present
The conventional high-temperature resistant rubber of in the market is ethylene propylene diene rubber and 4 third fluorubber, and they are respectively provided with excellent resistance to elevated temperatures,
Ageing-resistant performance, but the performance of the single resistance to superheated steam of glue kind is not still good enough.
The content of the invention
Present invention aims at a kind of resistant to elevated temperatures rubber composition is proposed, tolerance performance is good, and service life is long.
A kind of resistant to elevated temperatures rubber composition, its composition is counted as follows by weight：
35-45 parts of ethylene propylene diene rubber,
18-24 parts of polyisoprene rubber,

5-9 parts of age resistor,
1-3 parts of antioxidant,
3-8 parts of accelerator,
8-15 parts of ethanol,
5-10 parts of paraffin oil,
0.5-3.6 parts of sodium pyrophosphate.
A kind of above-mentioned resistant to elevated temperatures rubber composition, its composition is counted as follows by weight：
40 parts of ethylene propylene diene rubber,
22 parts of polyisoprene rubber,
10 parts of vulcanizing agent,
7 parts of age resistor,
2 parts of antioxidant,
5 parts of accelerator,
12 parts of ethanol,
6 parts of paraffin oil,
2.8 parts of sodium pyrophosphate.
A kind of above-mentioned resistant to elevated temperatures rubber composition, wherein, the vulcanizing agent is vulcanizing agent PDM.
A kind of above-mentioned resistant to elevated temperatures rubber composition, wherein, the age resistor is p phenylenediamine type antioxidant.
