Abstract

The invention relates to a formula of an automobile radiator rubber hose. The formula of the automobile radiator rubber hose is characterized in that the raw materials comprise, 70-75 parts of oil-extended type ethylene-propylene-diene monomer, 50-55 parts of ethylene-propylene-diene monomer, 3-4 parts of zinc oxide, 1-1.5 parts of stearic acid, 130-135 parts of N650 carbon black, 140-145 parts of N990 carbon black, 120-125 parts of paraffin oil, 2-3 parts of promoter BZ, 2-3 parts of promoter PZ, 3-4 parts of promoter TMTD, 2-3 parts of promoter DTDM, and 0.5-1 part of sulphur. The beneficial effects comprise that the hose is long in service life, resistant to high temperature and high in pull resistance, is reduced in cost through the reasonable ratio, and does not wrinkle when sleeving and withdrawing of a core rod are performed.

Description

A kind of formula of automobile radiator rubber hose
Technical field
The present invention relates to rubber synthesis field, be specifically related to a kind of formula of automobile radiator rubber hose.
Background technology
For reducing atmospheric drag, meet the requirement of most of automobile reduction property energy expenditure, body of a motor car and engine structure are just becoming more and more compacter, and simultaneously for improving fuel utilization ratio, Automobile Motor Design must be suitable for working at a higher temperature.Under these two factors cause bonnet, temperature constantly raises, and the working temperature of automobile cooling system is also in rising.Under bonnet, temperature normally 110-125 DEG C around handed over by scatterer, and local top temperature can reach more than 140 DEG C.Automobile cooling temperature in traveling can reach 90---and 110 DEG C.For automobile radiators cooling fluid sebific duct, oil-proofness and the chemical stability of good thermotolerance and ozone resistance and excellence must be had.
Summary of the invention
The invention provides a kind of formula of automobile radiator rubber hose, material adopts reasonably combined, extends the work-ing life of sebific duct.
A kind of formula of automobile radiator rubber hose, it is characterized in that, each ratio of component of starting material is oil extended EPDM 70-75 part, terpolymer EP rubber 50-55 part, zinc oxide 3-4 part, stearic acid 1-1.5 part, N650 carbon black 130-135 part, N990 carbon black 140-145 part, paraffin oil 120-125 part, accelerant B Z2-3 part, promotor PZ2-3 part, Vulcanization accelerator TMTD 3-4 part, vulkacit D TDM2-3 part, sulphur 0.5-1 part.
The ethylene content of described oil extended EPDM is 75%, and filling naphthenic oil content is 30%; The ethylene content of described terpolymer EP rubber is 68%.
The present invention's benefit effect: sebific duct long service life, resistance to elevated temperatures and tensile property high, rational proportioning reduces the cost of sebific duct, and wrinkle resistant when carrying out being inserted in and exiting of plug.
Embodiment
The each component preferred proportion of starting material is
Oil extended EPDM 70 parts, terpolymer EP rubber 50 parts, 3 parts, zinc oxide, stearic acid 1-part, N650 carbon black 130 parts, N990 carbon black 140 parts, paraffin oil 120 parts, accelerant B Z2 part, promotor PZ2 part, Vulcanization accelerator TMTD 3 parts, vulkacit D TDM2 part, 0.5 part, sulphur.
Wherein the ethylene content of oil extended EPDM is 75%, and filling naphthenic oil content is 30%; The ethylene content of terpolymer EP rubber is 68%.
The present embodiment and the production of usual production and comparing of performance:
The present embodiment Usual production
Extruded velocity Higher Tell somebody what one's real intentions are
The resistance to collapsing of sebific duct internal layer when sabot being wound around and weaving Better Poor
Low temperature permanent (preventing from leaking at fixing place) Poor Better
Set resistant Poor Better
Shaping on plug Be easier to More difficult
