Description
Technical field
The present invention relates to technical field of automobile, particularly relate to a kind of automobile oil seal sealing-ring.
Background technology
Traditional with sealing-ring taking common nitrile rubber (NBR) as main starting material, its formulating of recipe is often using tear resistance, wear resisting property and anti-extrusion performance as important considerations, not fully taking into account it in formulating of recipe process uses the sealing-ring of medium and operating mode can not meet service requirements far away in self-lubricating property, resistance toheat, ageing-resistant performance etc., therefore can very easily be distorted and break because torsion increases when assembling, it may also be useful to the life-span is short.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cost low, the automobile oil seal sealing-ring of stable performance.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of automobile oil seal sealing-ring is be made up of the component of following weight part number: natural rubber 25-35 part, ethylene-propylene rubber(EPR) 10-20 part, paraffin oil 4-6 part, plam oil 3-5 part, sulphur 1.5-3 part, ceramic 2-4 part, xylogen 4-6 part, nano silicon 3-5 part, anti-aging agent 1.5-2.5 part, polyoxyethylene glycol 3-5 part, dimethyl silicone oil 2-3 part, urethane 1.5-2 part, Vaseline 1-3 part, rare-earth modifier 4-6 part, sizing agent 2-3 part, linear polyethylene 4-6 part, thermal silica 4-6 part; During preparation, by above-mentioned each component in kneader evenly mixing, at 140-170 DEG C process 2 hours, be made into sizing material, technique is prepared into sealing-ring routinely;
Above-mentioned rare-earth modifier is made up of the component of following weight part number: rare earth 60 parts, silicone oil 2 parts, alumina powder 2 parts, plam oil 2 parts, 2 parts, carbon fiber, stearic acid 3 parts, ring second ketone 2 parts, vinylbenzene 2 parts, Graphene 2 parts, humic acids 0.5 part, W-Gum 5 parts, tealeaves alkaloid 4 parts, rosined soap 2 parts, sodium lignosulfonate 1.5 parts, asbestos powder 1 part, titanium dioxide 1.5 parts; Preparation technology is as follows:
1) being dispersion medium by rare earth, alumina powder, asbestos powder and titanium dioxide taking dehydrated alcohol, wherein the mass ratio of material and ethanol is 1:15, ultrasonic disperse 1 hour on ultrasonic cleaning machine;
2) compound through ultrasonic disperse is put into nylon ball grinder, adding stearic acid, tealeaves alkaloid, carbon fiber, vinylbenzene, Graphene and sodium lignosulfonate again, take agate ball as abrading-ball, ball material mass ratio is 7:1, when rotating speed is 150 revs/min, continuous ball milling 2 hours;
3) powder complete for ball milling is poured in powder dish together with agate abrading-ball, dry at 80 DEG C, the powder dried is sieved, take out agate abrading-ball, grind, until without, till bigger reunion, so far, the preparation of mixed powder is complete;
4) by step 3) in mixture mix with silicone oil, plam oil, ring second ketone, humic acids, W-Gum and rosined soap, low-temperature bake 2-3 hour under 50-70 DEG C of environment, take out, be ground into powder.
The invention has the beneficial effects as follows: the present invention has the advantage of high strength, low compression deformation, and high-low temperature resistant, performance is remarkable, there will not be fracture, metamorphism in long-time work.
