The composition comprises the following components in part by mass: 100 parts of EPDM crude rubber, 3 to 10 parts of zinc oxide, 2 to 6 parts of polyethylene glycol, 1 to 3 parts of stearic acid, 0.5 to 2 parts of anti-aging agent RD, 2 to 5 parts of anti-aging agent RD, 60 to 170 parts of fast extruding furnace black, 20 to 50 parts of semi-reinforcing furnace black, 40 to 95 parts of paraffin oil, 0.8 to 2 parts of accelerator zinc dibutyl dithiocarbamate (BZ), 0.4 to 0.8 part of accelerator tetramethylthiuram disulfide (TMTD), 0.7 to 1.5 parts of accelerator dipentamethylene thiuram hexasulfide (DPTT), 0.8 to 2.0 parts of accelerator dithiodimorpholine (DTDM) and 0 to 0.5 part of sulfur. The radiator rubber hose made of EDPM rubber has the characteristics of stable process performance, long service life and the like, and can completely meet the current using requirement.
Description
Technical field
The present invention relates to the rubber technology field, relate to a kind of EPT rubber composition that is used for the efficient vulcanization system of radiator rubber hose particularly.
Background technology
Along with the develop rapidly of automotive industry, automobile just develops this towards light-duty, efficient, economic direction and just requires body of a motor car and engine structure to become more and more compacter.Simultaneously, for improving fuel utilization ratio, the work under the higher temperature that is adapted at of Automobile Motor Design.These two factors cause that temperature constantly raises under the bonnet.The working temperature of automobile cooling system is also raising simultaneously.
Normally 110～125 ℃ of temperature under the bonnet around the radiator rubber hose, local top temperature can reach 140 ℃ (or higher).The coolant temperature of automobile can reach 90～110 ℃ in travelling.When being used for the automobile radiators sebific duct, terpolymer EP rubber (EPDM) is the most excellent elastomer material.EPDM had both had good thermotolerance and ozone resistance, had excellent cold-resistant but fluidity and chemical stability again.
The current vulcanization system that is used for the terpolymer EP rubber of radiator rubber hose has three kinds: conventional sulfur cross-linking system, efficient vulcanization system and peroxide vulcanizing system.Wherein conventional vulcanization system is prone to the shortcoming of bloom because resistance toheat is poor, can not satisfy service requirements; Though the peroxide vulcanizing system thermotolerance is fine, exist to cost an arm and a leg the problem of complex manufacturing.
Summary of the invention
The object of the present invention is to provide a kind of EPT rubber composition that is used for the efficient vulcanization system of radiator rubber hose, to better meet current service requirements.
The component of the EPT rubber composition of the said efficient vulcanization system that is used for radiator rubber hose with the massfraction ratio is:
Preferably using 125 ℃ of mooney viscosities of ML (1+4) in the present invention is 60～80 Ethylene Propylene Terpolymer rubber, makes sizing material have higher mooney viscosity, in extrusion, has the good anti-flat property of collapsing thereby given sizing material.
Select fast extrusion carbon black and semi-reinforcing hydrocarbon black and usefulness among the present invention for use, both given the product higher production efficiency, product reinforcing property preferably is provided again.
Select the vulcanization system of the high promotor of low-sulfur (or not having sulphur) in the present invention for use, given sizing material good heat-resisting and cold-resistant but fluidity ability.
The anti-aging agent of Jia Ruing is that RD is 2 in the present invention; 2; 4-trimethylammonium-1; 2-dihyaroquinoline, accelerant B Z are that zinc dibutyl dithiocarbamate, TM monex TD are that tetramethyl-thiuram disulfide, vulkacit D PTT are that two (pentamethylene) thiurams of six sulfurations, vulkacit D TDM are dithiodimorpholine.
It is stable to use the radiator rubber hose of terpolymer EP rubber production of the present invention to have processing performance, and characteristics such as long service life can satisfy current service requirements fully.
