Description
Technical field
The present invention relates to a kind of silastic product, more particularly, to a kind of modified, high temperature resistant air filter silica gel air induction hose.
Background technology
Automobile engine is very accurate parts, and minimum impurity can all damage engine.Therefore, air is into gas
Before cylinder, it is necessary to first pass through air cleaner（Air filter）Fine and closely woven filtering, cylinder could be entered.If make in running car
Used dirty air filter, engine charge can be made insufficient, make fuel oil incomplete combustion, cause engine job insecurity, power
Decline, the increased phenomenon of fuel consumption occurs.Therefore, automobile must keep the cleaning of air filter, and air filter is guarding for engine
God, the quality of air filter state are related to the life-span length of engine.Wherein with air filter performance it is closely bound up be air filter
Air induction hose, because air filter needs to work under the high temperature conditions for a long time in the process of running, therefore air induction hose also needs
Will can high temperature resistant, in order to avoid influence the overall operating efficiency of air filter.Organic silicon rubber is that output is maximum in organosilicon industry
A kind of product, thus as a mostly important branch in field of organic silicon.Due to the Si-O-Si keys in organic silicon rubber
Exist in the form of cross-linked network, therefore organic silicon rubber has a good high and low temperature resistance, weatherability, warm radiation hardness and absolutely
The special natures such as edge, there is its extensively and unique use in fields such as daily life life, electric, industry and Aero-Space
On the way.
Such as a kind of a kind of automobile-used rubber tube of high temperature resistant announced in Chinese patent document, its application publication number are CN
104592606 A, it is mainly made up of hydrogenated nitrile-butadiene rubber, nitrile rubber, ethylene propylene diene rubber and other auxiliary agents.It is this resistance to
Hot car rubber tube, not only oil resistance raising, is provided simultaneously with good resistance to elevated temperatures, is not easy out in 120 DEG C of high temperature
Existing aging, be hardened, embrittlement, fracture the problem of, service life increases significantly.But this high-temperature resistant rubber pipe still has many not
The place of foot, such as its main component are hydrogenated nitrile-butadiene rubber, nitrile rubber, although these rubber have certain heat-resisting quantity
Can, but its resistant to elevated temperatures upper limit is relatively low, often can only at 150 DEG C steady operation, therefore when temperature in use is more than 150 DEG C just
It can not work on.
