Description
Technical field
The present invention relates to the sebific duct technical field, particularly a kind of turbine booster hose of ethyleneacrylate rubber and preparation method.
Background technique
Along with the more and more strictness of automobile emissions standards, the automaker not only will satisfy environmental requirement, satisfies client's demand simultaneously again, guarantees enough driving enjoyment.Turbosupercharger just in time can satisfy to reduce discharges and the raising fuel economy, can be not cost to lose driving enjoyment again simultaneously.Turbosupercharger can provide better fuel economy, because the supercharging meeting provides more air to the firing chamber, makes burning more thorough, discharges cleaner.Turbosupercharger is spread on many type automobiles by sport car or the equation motorcycle race that contest is used, and its market demand is huge.In Europe, turbosupercharger has accounted for 50%, in the Asia, the U.S. also all increasing.Turbosupercharger has become the main flow direction that improves power performance.This just mean not only require high temperature resistant, but also require the exploitation of turbosupercharging sebific duct of anti-fuel oil imperative with development.
Though butyronitrile rubber can fuel oil resistance, ageing-resistant performance and heat resistance are relatively poor; Glue has good ageing-resistant performance though hydrogenation is fixed one's eyes upon, and heat resistance is also better, can not surpass 140 ℃, and price is more expensive; Fluorine rubber heatproof degree performance surpasses 200 ℃, and oil resistance is also fine, but processing difficulties costs an arm and a leg; High temperature resistant, the low temperature performance excellent of silicone rubber, but poor mechanical property are difficult for processing.This shows, can not adapt to the requirement of Hyundai Motor in the past with the conventional fittings of butyronitrile rubber and neoprene preparation, and fluorine and silicone rubber use uneconomical, ethylene-acrylate rubber is uniquely a kind ofly can satisfy high temperature resistant simultaneously and chemically-resistant material (fuel oil+acid+oily l/ water) and cost acceptable rubber, adopt ethylene-acrylate rubber to develop the turbosupercharging sebific duct, can satisfy the usage requirement of automobile fully.
Summary of the invention
Purpose of the present invention mainly is in order to satisfy the continuous rising that automobile more and more adopts diesel engine and engine temperature, must to adopt the turbosupercharging sebific duct, and this sebific duct requires not only high temperature resistant but also require heat resistant oils, could satisfy usage requirement.
Ethylene-acrylate rubber (AEM) is since 1975 release, because it has valuable resistant of high or low temperature (175 ℃～-40 ℃), heat resistant oils, compression permanent deformation and combination property such as wear-resisting, compare with fluorine glue, its low price, superior performance, ethylene-acrylate rubber is that common acrylate rubber obtains through modification, compare with traditional acrylate rubber (ACM), its operating temperature range is wideer, 175 ℃ of high temperature of the highest ability, and excellent oil resistance is arranged, can satisfy usage requirement.
Structure of the present invention is a three-decker, is successively from the inside to the outside: ethylene acrylate rubber layer 1, aramid line layer 2, ethylene acrylate rubber layer 3, the aperture of sebific duct is according to the concrete configuration that requires of various automotive hoses.
The preparation method of this turbosupercharging pipe is as follows:
1) pipe embryo manufacture process
Extrude interior glue: the extrusion temperature in control each stage of extruder, from the head to the screw rod, be followed successively by 110 ℃～60 ℃, 90 ℃～50 ℃, 90 ℃～40 ℃, 90 ℃～40 ℃, 90 ℃～40 ℃.
Enhancement layer: select aramid line, adopt reticular structure.
Extrude outer glue: setting outer glue extrusion temperature is 110 ℃～60 ℃, 90 ℃～50 ℃, and 90 ℃～40 ℃, 90 ℃～40 ℃, 90 ℃～40 ℃.Extruding sebific duct thickness determines according to the requirement of the total wall thickness of sebific duct.
2) sulfidization molding process:
The turbosupercharging pipe is through one section and post vulcanization aftershaping.The one step cure parameter: sulfurize temperature is 130～180 ℃, and cure time is 5～60min; The post vulcanization parameter: sulfurize temperature is 150～200 ℃, and cure time is 1～6h.
The present invention satisfies the usage requirement of the not only high temperature resistant but also heat resistant oils of automobile turbosupercharging pipe.
