Description
Technical field
The present invention relates to automobile turbosupercharging sebific duct technical field, particularly a kind of fluorine rubber and resistance oil silicone rubber, silicone rubber turbosupercharging sebific duct and preparation method thereof.
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.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.
Automotive industry is a pillar industry in national economy, flourish along with industry in recent years, and turbosupercharger is spread on many type automobiles by sport car or the equation motorcycle race that contest is used, and the turbosupercharger market demand is huge.The turbosupercharger sebific duct is used to carry air and waste gas, will bear high temperature more than 200 degrees centigrade usually, plays the effect of connection, damping, noise reduction, will make supercharger speed height, pressure ratio increase cause serious consequences such as engine operation is rough in case damage.Because the turbosupercharger silicone tube is with high content of technology, the production difficulty is big, the present domestic professional production producer that still do not have.Some high-grade cars of American-European countries require to adopt this kind silicone tube, general car also has the ethylene-acrylate of employing turbosupercharging sebific duct, but adopt the high-temperature resistant of ethylene-acrylate rubber can only arrive 175 ℃, and employing silica gel, maximum temperature can get at 250 ℃, and the fuel resistance of fluorine glue can be more superior than ethylene-acrylate rubber, so glue is fluorine glue in adopting, outer glue is that the turbosupercharging sebific duct of silicone rubber is fit to the more and more higher engine system of temperature requirement more.
Summary of the invention
Purpose of the present invention mainly is to solve the requirement that existing turbosupercharging sebific duct can differ from high temperature resistant, heat resistant oils, osmotic-pressure-tolerant.Because fluorine rubber contains fluorine atom and a kind of synthetic high polymer elastomer on the carbon atom of main chain or side chain, the electronegativity of fluorine atom is high, so have splendid fuel resistance.With the internal layer of fluorine rubber design at sebific duct, can guarantee the fuel resistance energy of sebific duct inside, silicone rubber is that a kind of molecular chain has concurrently organic and macromolecular material inorganic in nature, because of its molecular backbone alternately is made of (Si-O-Si-) silicon atom and oxygen atom, and bond energy is than big many of ordinary rubber, so silicone rubber has good heat endurance (50 ℃～250 ℃), with the skin of this kind silicone rubber design at sebific duct, can satisfy the high-temperature behavior of external engine, silicone rubber has novel oil resistant silica gel through after the modification, under the condition of heatproof permission, make silica gel have certain oil resistance, the design of this kind silica gel in the middle level of turbosupercharging pipe, has not only been satisfied oil resistance but also satisfied heat-resisting quantity.
Fluorine rubber of the present invention and resistance oil silicone rubber, silicone rubber turbosupercharging sebific duct have four-layer structure, comprise fluorine rubber internal layer 1, oil resistant silica gel middle level 2, aramid line 3 and silicone rubber skin 4; Interior layer thickness is 0.4～1.0mm, and middle level thickness is 1～4mm, and aramid line layer 0.1～2mm, outer layer thickness are 1～4mm.The aperture of sebific duct is according to the concrete configuration that requires of various automotive hoses.
