Description
Technical field
The present invention relates to synthetic rubber field, be specifically related to a kind of environmental protection brake sealing member.
Background technology
Rubber cup mainly refers to and is applied in the rubber seal that plays transmission of pressure and sealing function in the brake fluid system of car, Light-duty Vehicle, minibus, part bogie and clutch operating system, booster pump system.Rubber cup is also applied on household electrical appliance, as is used in the rubber cup on two-tub washing machine cylinder body, and cylinder body is played to sealing function.Rubber cup is a kind of one of important rubber product of function that is widely used in rubber item.
The principal feature of rubber cup:
1) leather cup in master cylinder and wheel cylinder must have certain elasticity and compression set and wear resistance, to guarantee that leather cup in use has certain return ability and the sealing property of transmitting hydraulic pressure.2) at high temperature, (the lower hydraulic pressure resistant medium of 100～120 ℃ and low temperature (30～50 ℃) is good, leather cup long period in braking sealing device contacts with braking fluid, therefore require it to there is good anti swelling to braking fluid (synthetic liquid, mineral oil), do not allow, under high temperature, low temperature and static room temperature, seepage occurs.
Major ingredient when rubber cup is produced in prior art mostly is rubber paracril, paracril to have oil-proofness fabulous, wear resistance is higher, and thermotolerance is better, and bonding force is strong, but its lower temperature resistance is poor, ozone resistance is poor, electrical property is inferior, and elasticity is low, under low temperature environment, uses for a long time, its sealing property can reduce greatly, need to improve existing leather cup sizing compound formula.
Summary of the invention
The invention provides a kind of environmental protection brake sealing member, sealing member of the present invention has excellent high-low temperature resistant, oil resistant, resistance to solvent and chemical resistance, simultaneously good mechanical property.
The present invention adopts following technical scheme:
A kind of environmental protection brake sealing member, the furnish component of described brake sealing member comprises terpolymer EP rubber, vulcanization leveller, stearic acid, aging dose, lubrication prescription, dispersion agent, linking agent, sulphur, high wear-resistant carbon black and semi-reinforcing hydrocarbon black.
As preferred technical scheme, above-mentioned furnish component is made up of following raw materials in part by weight: terpolymer EP rubber 10kg, vulcanization leveller 500g, stearic acid 200g, aging dose of 150g, lubrication prescription 250g, dispersion agent 200g, linking agent 200g, sulphur 30g, high wear-resistant carbon black 5kg, semi-reinforcing hydrocarbon black 1kg.
As preferred technical scheme, it is any that described vulcanization leveller also can be used as softening agent, tenderizer or releasing agent.
As preferred technical scheme, the mixture of the tensio-active agents such as the metallic soap compound that described dispersion agent is higher fatty acid.
As preferred technical scheme, described linking agent is dicumyl peroxide.
As preferred technical scheme, described terpolymer EP rubber is selected Keltan Eco5470, this rubber is bio-based EPDM, its ethylene raw is from sugarcane, but not oil is a kind of EPDM of Sustainable development, can break away from the dependence to petroleum-based products, reduce Carbon emission, more environmental protection.
Beneficial effect:
The present invention is by terpolymer EP rubber and other several compounding rubbers, improve the over-all properties of rubber unvulcanizate, by high wear-resistant carbon black, semi-reinforcing hydrocarbon black carries out respectively after modification mixing, use again linking agent processing, use as strengthening agent, improve the dispersiveness of filler in rubber unvulcanizate, improve filler addition, reduce material cost, the ozone resistance of the rubber unvulcanizate of gained and resistance to low temperature, resistance toheat improves greatly, there is wider use temperature scope than terpolymer EP rubber itself, better performance of technical process, lower starting material and production cost, meet the performance requriements of the component that domesticize.
