Head is often socketed with sealing ring, and owing to there being more greasy dirt inside air conditioning for automobiles, therefore sealing ring is easily corroded, meanwhile,
Gas that flexible pipe within air-conditioning often delivery temperature is higher or liquid, sealing ring after being heated readily volatilized go out abnormal flavour and harmful
Gas, these gases can lead in driver's cabin with pipeline, human body is produced bigger harm.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of corrosion-resistant, high temperature resistant and oil resistant automobile to seal
Circle and preparation method thereof.
In order to realize the purpose of the present invention, adopt the following technical scheme that
A kind of automobile oil-resistant seal ring, is made up of the raw material of following weight portion:
Preferably, it is made up of the raw material of following weight portion:
Preferably, it is made up of the raw material of following weight portion:
Preferably, 300 mesh standard sieves crossed by wollastonite in powder.
Further, the preparation method of a kind of automobile oil-resistant seal ring, comprise the following steps:
(1) each raw material of corresponding weight portion is weighed respectively；
(2) natural rubber and silicone rubber are joined in banbury, be heated to 95-105 DEG C, mixing 8-12min, then rise
Temperature, to 120-135 DEG C, adds remaining remaining raw material, mixing 30-50min；
(3) glue stuff compounding prepared by step (2) is carried out mill molding by mill；
(4) being placed in the mould of vulcanizing equipment by the sizing material after step (3) molding, curing temperature is 220-240 DEG C,
Cure time is 5min；Then the demoulding is carried out；
(5) product after step (4) being vulcanized carries out deburring, prepares satisfactory oil-resistant seal ring.
Beneficial effects of the present invention:
The present invention, with natural rubber, silicone rubber as rubber raw materials, by adding bamboo carbon fiber, strengthens the absorption of sealing ring
Property, absorption abnormal flavour and harmful gas；Adding magnesium hydroxide, wollastonite in powder and Firebrake ZB is filler, improves the acidproof of sealing ring
Caustic corrosion, oil resistivity and wearability；The acicular texture that wollastonite in powder is special, improves the mechanical property of sealing ring, such as stretching
Intensity；Add white carbon black by with other filler synergism, further increase wearability and the intensity of sealing ring；The present invention
Sealing ring oil resistivity and wearability strong, there is resistance to elevated temperatures, do not soften under high temperature, service life is long.
