Abstract
The invention discloses a formula of modified ethylene-propylene-diene monomer (EPDM) rubber. The modified EPDM rubber comprises EPDM rubber and additives, wherein the additives comprise tricresyl phosphate serving as a flame retardant, 2,6-butylated hydroxytoluene serving as an antioxidant, zinc oxide serving as a light stabilizer, vinyltriethoxysilane serving as a coupling agent, sulfur serving as a cross-linking agent and zinc dimethyldithiocarbamate serving as an accelerator. A high-temperature-resistant agent and a corrosion inhibitor are added into the EPDM rubber, so that a rubber pipe made of the modified EPDM rubber has high-temperature resistance, electric corrosion is slowed down, and the service life of the rubber pipe is prolonged; and an impact modifier is added, so that the mechanical properties and elasticity of the rubber pipe can be improved, and the rubber pipe is difficult to break.
Description
Technical field
The present invention relates to a kind of plastic formula, be specifically related to a kind of prescription of modified EPT rubber.
Background technology
Along with the develop rapidly of automotive industry, the improving constantly of vehicle performance, the rubber hose that automobile is used has proposed higher technical requirements, and sebific duct must stand the high temperature test more than 150 ℃ around the mover; If sizing material contains zinc, high temperature can generate insoluble precipitate with the anti-corrosion of metal additive reaction in the quench liquid down, can block the pipeline of mover, makes the temperature of car engine cooling system increasingly high.
The automobile radiators sebific duct is the flexible conduit that connects between motor car engine and the scatterer, and major function is to carry quench liquid, guarantees that engine health turns round normally.Terpolymer EP rubber is as the main raw of radiator rubber hose, and the working temperature of present domestic radiator rubber hose reaches 125 ℃, uses the terpolymer EP rubber of sulfur cross-linking can't satisfy current request for utilization.
Galvanic corrosion is meant automobile in operational process, forms potential difference between mover and the scatterer, under secular high temperature and high pressure effect, and the phenomenon that the radiator rubber hose inwall is cracked, it has a strong impact on the work-ing life of sebific duct.
Therefore, the novel tertiary ethylene-propylene rubber(EPR) material of a kind of high temperature resistant, anti-electrocorrosion, good toughness, long service life is the problem of current research.
Summary of the invention

Technical scheme of the present invention is that a kind of prescription of modified EPT rubber comprises terpolymer EP rubber and additive; Described additive is high temperature resistant dose, inhibiter, static inhibitor, anti-impact modifier and coupling agent; Described high temperature resistant dose is organo-silicone rubber, and inhibiter is a coloured glaze base benzothiazole, and static inhibitor is a polyoxyethylene stearic acid ester; Anti-impact modifier is a Yodo Sol GH 28, and coupling agent is an aminopropyl triethoxysilane.
In preferred embodiment of the present invention; The weight proportion scope of each composition is that terpolymer EP rubber accounts for 81%-89% in the prescription of said modified EPT rubber; Organo-silicone rubber accounts for 3.5%-5.3%, and coloured glaze base benzothiazole accounts for 1.7%-2.9%, and polyoxyethylene stearic acid ester accounts for 1.3%-2.4%; Yodo Sol GH 28 accounts for 3.4%-5.6%, and aminopropyl triethoxysilane accounts for 1.1%-2.8%.
In preferred embodiment of the present invention; The weight proportion of each composition is that terpolymer EP rubber accounts for 85% in the prescription of said modified EPT rubber; Organo-silicone rubber accounts for 4.3%, and coloured glaze base benzothiazole accounts for 2.5%, and polyoxyethylene stearic acid ester accounts for 1.7%; Yodo Sol GH 28 accounts for 4.4%, and aminopropyl triethoxysilane accounts for 2.1%.
According to the invention is a kind of prescription of modified EPT rubber; Through in terpolymer EP rubber, adding high temperature resistant dose, inhibiter; That the sebific duct that modified EPT rubber is processed has is high temperature resistant, slow down electrocorrosion; Increase the work-ing life of sebific duct, the anti-impact modifier of interpolation can improve the mechanical property and the elasticity of sebific duct, makes not easy fracture of sebific duct.
