Raise；In addition oxidized compound is with the addition of in the fuel component for being used.High temperature, acidifying are shown as in fuel system（Acid
Property gasoline）And high-pressure trend, the life requirement to sebific duct is very harsh, thus proposes high pressure resistant, the low-penetration fuel glue of exploitation
The requirement of pipe.In addition electromotor develops to high-power, high-revolving direction, causes the acute variation of sebific duct operating ambient temperature,
The material and processing method of rubber tube of automobile fuel oil is promoted to develop and update constantly.Can not meet the acidifying of heat-resisting and fuel-resistant
Require, to reach the service life for extending fuel hose, improve its endurance quality and meet environmental requirement, solve engine environment
The purpose of the problems such as ambient temperature is too high and fuel oil medium changes.
Epichlorohydrin rubber is epichlorohydrin homopolymers（CO）, or the bipolymer of epoxychloropropane and oxirane
（ECO）, or added with Third monomer（Expoxy propane）Terpolymer.With oil resistant, ozone resistance, heat resistance compares butyronitrile
Rubber is good, the features such as breathability is little.
CSM be with polyethylene as main material Jing chlorinations, chlorosulfonation and it is obtained with high saturation
The chloride special elastic body material of chemical constitution, belongs to the specific rubber kind of high-performance quality.Its white in appearance or milky
Elastomeric material, has thermoplasticity.Due to containing chlorine sulphonyl active group in molecular structure, therefore high activity is shown, and especially with resistance toization
Learn dielectric corrosion, ozone-resistant oxidation and the performance such as resistance to oil corrosion, fire-retardant project, also with it is anti-time change, heat-resisting, anti-ionizing radiation,
Low temperature resistant, anti scuffing and electrical insulating property and excellent mechanical performance.
Therefore, using both the above material the characteristics of, process technology is compounded using rubber, appropriate design formula is made the best use of the advantages and kept away
It is short, develop a kind of high temperature resistant for automobile brake rubber hose outer layer glue, resistance to braking fluid elastomeric material it is necessary, will produce
Huge economic benefit and social benefit.
