Description
Technical field
The present invention relates to a kind of purifier gasket, relate in particular to the purifier gasket that a kind of automobile engine oil is used.
Background technology
Oil filter is arranged in engine lubrication system.Its upstream is lubricating oil pump, and the downstream is to need each component of lubricating in the engine.Its effect is to carrying out filtering from detrimental impurity in the machine oil of oil pan, with kinematic pairs such as the engine oil supplying bent axle of cleaning, connecting rod, camshaft, supercharging blower, piston ring, plays lubricated, cooling, cleanup action, thereby prolongs the life-span of these component.The cover that gasket is made up of one or several part is fixed on lasso of bearing or the packing ring and with another lasso or packing ring and contacts or form narrow labyrinth clearance, prevents that lubricating oil from spilling and foreign object is invaded.
In oil filter, the fluorine glue of selecting for use of the general usefulness of gasket is done the main body material, and it is high temperature resistant to reach 200 degree, low temperature resistantly can arrive-20 and spends.But at northern frore area, fluorine glue then can lose its use properties.Cause the purifier leakage of oil.Perhaps use HNBR hydrogenated nitrile-butadiene rubber gasket, the auspicious father-in-law of chloroprene rubber CR121, hydrogenated nitrile-butadiene rubber ZP2020(Japan), Zinc Stearate, coumarone, 2-thiol group benzimidazolyl, clorafin, semi-reinforcing hydrocarbon black SRF, montmorillonite powder, adipic acid ester, promotor PZ, promotor TETD, linking agent TAC, anti-aging agent RD, antioxidant 1010, modification infusorial earth disclose a kind of sealing-ring for purifier drain pan and loam cake as CN102942723A, it is made up of following raw material:.Or use the nitrile rubber gasket, comprise as the major ingredient of the disclosed rubber seal of CN102952299A: the nitrile rubber 2865 of 28～36 weight parts; Auxiliary material comprises: the carbon black 330 of 10～18 weight parts, half reinforcement of 10～18 weight parts, the dioctyl ester of 1～6 weight part, 0.35 the zinc oxide of～0.65 weight part, 0.02 the sulphur of～0.05 weight part, 0.2 the hard acid ester of～0.7 weight part, 0.3 the antioxidant 4010NA of～0.7 weight part, 0.3 the anti-aging agent RD of～0.7 weight part, 0.15 the promotor T.T.C of～0.3 weight part, the calcium carbonate of 2～7 weight parts, 0.8 the altax of the EN-100 of～1.2 weight parts and 0.15～0.25 weight part.
Summary of the invention
The object of the present invention is to provide a kind of oil filter gasket, select the fine content 33% of propylene for use, the paracril of mooney viscosity 50-60 is that major ingredient is prepared, the gasket processing characteristics that makes is excellent to satisfy the product high and low temperature resistance simultaneously, can satisfy 135 ℃ to-40 ℃ use range.
Oil filter gasket provided by the invention, contain following component by weight: paracril 100, dicumyl peroxide 1～3, as it is 1 part, 1.1 part, 1.3 part, 1.5 part, 1.8 part, 2.2 part, 2.6 part, 2.9 part etc., ZnO1～10, as it is 1.4 parts, 2.1 part, 3.3 part, 4.5 part, 5.8 part, 6.2 part, 7.6 part, 8.9 part, 9.5 part etc., stearic acid 0.5～2, as it is 0.8 part, 1.1 part, 1.3 part, 1.6 part, 1.8 part etc., anti-aging agent RD 0.5～5, as it is 0.8 part, 1.3 part, 1.9 part, 2.3 part, 2.5 part, 2.8 part, 3.3 part, 3.6 part, 4.5 part, 4.7 part etc., antioxidant MB 0.5～5, as be 0.8 part, 1.3 part, 1.9 part, 2.3 part, 2.5 part, 2.8 part, 3.3 part, 3.6 part, 4.5 part, 4.7 part etc.
Paracril is made through emulsion polymerization by divinyl and vinyl cyanide, and paracril mainly adopts the production of low temperature emulsion polymerization, and oil-proofness is fabulous, and wear resistance is higher, and thermotolerance is better.The fine content 33% of propylene in the used paracril of the present invention, mooney viscosity 55, mooney viscosity claim again to rotate (Mooney) viscosity, are the numerical value of measuring with mooney's viscosimeter, can reflect the elastomeric polymerization degree and molecular weight basically.The present invention selects for use specific paracril can guarantee that the product processing characteristics excellence that makes can satisfy the product high and low temperature resistance simultaneously.
Dicumyl peroxide claims vulcanizing agent DCP again, is a kind of strong oxidizer, initiator of polyreaction.The present invention selects for use the superoxide dicumyl peroxide as vulcanizing agent, makes the resistance to elevated temperatures excellence that makes material to have the low compression set rate simultaneously.
ZnO is used as the strengthening agent of rubber in goods of the present invention, so that rubber has good anti-corrosion, tear strength and elasticity, elongation.
Stearic acid is octadecanoic acid, contains the saturated fatty acid of 18 carbon atoms.As vulcanization leveller, also can be used as softening agent and tenderizer in the present invention, also have the effect of releasing agent simultaneously.
Anti-aging agent can prevent or suppress such as factors disrupt product propertiess such as oxygen, heat, light, ozone, mechanical stress, heavy metal ion, prolong gasket storage and the Synergist S-421 95 in work-ing life.Anti-aging agent of the present invention uses RD, the MB combination of amine and heterocyclic, makes the oil resistance excellence that makes product.
