Description

A kind of chlorinated polyethylene rubber material
Technical field
The present invention relates to a kind of chlorinated polyethylene rubber material, concrete, relate to prepare the chlorinated polyethylene of sebific duct Alkene material, more specifically, relates to a kind of chlorinated polyethylene material for automobile cooling water pipe.
Background technology
Cooling water pipe is typically to be formed (also having gum rubber tubing product) by hose lining, outer glue and the enhancement layer being clipped in each glue middle, Sizing material used is mostly ethylene propylene diene monomer (EPDM) material, and two-layer braiding enhancement layer uses polyester, polyvinyl alcohol or artificial silk Fiber.Cooling water pipe is that automobile is improved quality and required one of the strictest vitals.In vehicle traveling process, Heat of engine scatters and disappears too much, increases fuel oil consumption, and the fuel oil being condensate on cylinder wall flows to dilution profit in crankcase Lubricating oil, abrasion aggravation；Engine overheat, it is abnormal that aeration quantity reduces burning, and engine power declines insufficient lubrication, Unstable wear.And automobile cooling water pipe transmission coolant makes automobile engine obtain the cooling of appropriateness, and it is maintained at Work within the scope of suitable temperature.Automobile cooling water pipe operating temperature is higher, and heat aging property to be got well, the most right The requirement of resistance to coolant is the harshest, generally uses ethylene propylene diene rubber, silicone rubber or thermoplastic elastomers at present and enters Row produces, and cost of material is the highest.Along with the development advanced by leaps and bounds of auto industry, the need of automobile rubber tube The amount of asking also constantly is increasing, and producing high-quality various automobile rubber pipe has become one and break the problem at the eyebrows and eyelashes. The material producing automobile-used sebific duct is also being continuously updated, and market also requires that price is low, and the measured product of matter, this just gives The design of sebific duct and Producer propose new problem and challenge.
Summary of the invention
It is an object of the invention to provide a kind of chlorinated polyethylene rubber material, chlorinated polyethylene rubber prepared by this material Having good chemical-resistant resistance, resistance to ag(e)ing, other mechanical properties are the most fine.
Another object of the present invention provides a kind of chlorinated polyethylene rubber material for automobile cooling water pipe.
For realizing first goal of the invention of the present invention, adopt the following technical scheme that
A kind of chlorinated polyethylene rubber material, including:
