Abstract
The invention discloses high-pressure-resistant rubber relating to the technical field of rubber. The high-pressure-resistant rubber is prepared from the following raw materials in parts by weight: 70-80 parts of ethylene propylene rubber, 17-25 parts of butadiene-acrylonitrile rubber, 3-5 parts of epichlorohydrin rubber, 2-10 parts of stearic acid, 15-30 parts of carbon black, 2-10 parts of dithiocarbamate, 2-10 parts of polyethylene wax, 3-15 parts of paraffin and 12-15 parts of cured resin. By using the high-pressure-resistant rubber, the problem of poor high pressure resistance of the existing rubber is solved.
Description
Technical field
The present invention relates to field of rubber technology, especially a kind of high pressure resistant rubber.
Background technology
In the hydraulic efficiency system of automobile or mechanical means, normally connect with rubber hose between its oil cylinder and executive item, the rubber of existing rubber hose many employings single-material is made, owing to will bear the flowing of high-voltage oil liquid with rubber hose herein, easily cause the damage of sebific duct and cause leakage of oil, alter oil, therefore oil product is not only made to waste, severe patient even can cause the accident jeopardizing people's lives and properties, therefore produce a kind of easy to use, the life-span long, high pressure resistant and low-cost rubber hose is those skilled in the art needs the problem of solution badly.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high pressure resistant rubber, and it can solve the problem of existing rubber barotolerance difference.
In order to solve the problem, technical scheme of the present invention is: this high pressure resistant rubber, adopts the raw material of following weight part:
Ethylene-propylene rubber(EPR): 70 parts to 80 parts; Butyronitrile rubber: 17 parts to 25 parts; Epichlorohydrin rubber: 3 parts to 5 parts; Stearic acid: 2 parts to 10 parts; Carbon black: 15 parts to 30 parts; Dithiocar-bamate: 2 parts to 10 parts; Polyethylene wax: 2 parts to 10 parts; Paraffin: 3 parts to 15 parts; Curing resin: 12 parts to 15 parts.
In technique scheme, scheme can also be more specifically: described high pressure resistant rubber, adopts the raw material of following weight part to make: ethylene-propylene rubber(EPR): 73 parts to 76 parts; Butyronitrile rubber: 18 parts to 23 parts; Epichlorohydrin rubber: 3.6 parts to 4.3 parts; Stearic acid: 4 parts to 7 parts; Carbon black: 16 parts to 26 parts; Dithiocar-bamate: 4 parts to 7 parts; Polyethylene wax: 4 parts to 7 parts; Paraffin: 5 parts to 13 parts; Curing resin: 13 parts to 14 parts.

Owing to adopting technique scheme, the present invention has following beneficial effect:
The interpolymer of ethylene-propylene rubber(EPR) ethene of the present invention and propylene, generally be divided into ethylene propylene rubber and terpolymer EP rubber, have resistance to ozone, UV resistant, resistance to weather and ageing resistance excellent, electrical insulating property, chemical resistant properties, shock elasticity are fine, acid and alkali-resistance, the feature that proportion is little.
Butyronitrile rubber of the present invention is the interpolymer that divinyl and propylene are fine, has resistance to gasoline and aliphatic hydrocarbon oils, good heat resistance, and resistance to air loss, wear-resisting and water tolerance are fine, the feature that cohesive force is strong.
Epichlorohydrin rubber of the present invention is by epoxy chloropropane homopolymerization or the polymkeric substance by epoxy chloropropane and oxyethane copolymerization, there is resistance to aliphatic hydrocarbon and chlorinated hydrocarbon solvent, alkaline-resisting, water-fast, ageing-resistant performance is fabulous, adjacent hot, the resistance to air loss high feature of ozone resistance, weathering resistance.
1, owing to have employed ethylene-propylene rubber(EPR), butyronitrile rubber and epichlorohydrin rubber, combine the oil-proofness of the HI high impact elasticity of ethylene-propylene rubber(EPR), the high ageing resistance of epichlorohydrin rubber and butyronitrile rubber, make the rubber of synthesis have the feature of high resistance to pressure and alkaline-resisting, water-fast, ageing-resistant long service life.
2, owing to adopting polyethylene wax as protective agent, the persistency of rubber, hardness and wearability can be improved.
