Description
Technical field
The present invention relates to a kind of rubber hose, relate in particular to a kind of cleaned air pipe and preparation method thereof.
Background technology
Along with the continuous development of automotive industry, use the mover of turbocharging technology more and more in recent years.The use of turbocharging technology has improved the power of mover, has reduced energy consumption.But turbo charged use also causes the temperature of engine air inlet tube to increase substantially.Particularly under high rotating speed, serious having scurried more can cause the scarce machine oil phenomenon between piston-ring and the cylinder.Because waste gas has part gasoline or diesel oil exists, therefore, in the selection of hose material; Must select anti-gasoline and diesel exhaust material relatively preferably, and near the mover, temperature is higher; The highest instantaneous temperature can reach about 170 degree; Therefore, elastomeric material not only requires oil resistant, still requires high temperature resistant.
Rubber hose mainly is to connect mover and air filter, and it is nearer from mover as the integral part of inlet system; Therefore need be high temperature resistant, oil resistant, corrosion-resistant; Ageing-resistant; Low temperature resistant etc., its material has numerous species according to the difference of complete processing, for example NBR, EPDM, TPE and the auxiliary material of adding etc.
CN 102093623A discloses a kind of crankcase ventilation rubber hose, and said rubber hose comprises ethylene-acrylate rubber, acrylic elastomer, butyronitrile rubber, strengthening agent, softening agent, internal mold release, anti-aging agent, vulcanizing agent and promotor.
Originally conventional butadiene-acrylonitrile rubber material can't satisfy the use of conventional turbosupercharged engine because resistance to elevated temperatures is not enough.Therefore develop a kind of high temperature resistant better elastomeric material, it is more and more important just to seem.
