Abstract

The invention discloses a seal ring for an automotive filter. The seal ring is prepared from the components in percentage by weight as follows: 20% of raw rubber JSRN230S, 10% of natural rubber, 30.5% of carbon black, 8% of chlorinated polyethylene, 2.8% of softener, namely, dioctyl-phthalate, 1% of active agent, namely, zinc oxide, 2.6% of age resister, 2.3% of vulcanization accelerator, namely, dicumyl peroxide, 2% of magnesium oxide, 1.5% of self-lubricant, namely, unsaturated fatty acid, and the balance of engine oil. Based on a vast amount of experiments, according to the invention, the formulation design of the conventional seal ring for the automotive filter is elaborately changed, and the manufacturing process of two-stage mixing is adopted. Thus the novel seal ring for the automotive filter is manufactured, with significant improvements on the aspects of the tensile strength, the abrasion resistance, the stability, the tear resistance and the like, wherein the heat resistance property of a product is improved from 100 to 135 DEG C, and the anticorrosive capabilities of the engine oil and the fuel oil are improved greatly.

Description

The automobile filter sealing-ring

Technical field

The present invention relates to sealing-ring, particularly, is a kind of automobile filter sealing-ring.

Background technology

traditional seal ring for car filter is take common nitrile rubber (NBR) as main raw material(s), its formulating of recipe is often with tear resistance, wear resisting property and anti-extrusion performance are as the emphasis Consideration, but, owing in use can suffering from the strong corrosion of machine oil and fuel oil, and the orthodox car purifier that does not fully take into account its working medium and operating mode in the formulating of recipe process uses sealing-ring in self-lubricating property, resistance toheat, the aspects such as ageing-resistant performance can not satisfy service requirements far away, therefore can break because torsion increases very easily to be distorted when assembling, work-ing life is short.

Summary of the invention

Deficiency for the prior art existence, technical problem to be solved by this invention is, provide a kind of and all be significantly increased at aspects such as self-lubricating property, resistance toheat and ageing-resistant performances, the ability of opposing machine oil and fuel oil corrosion strengthens greatly, the automobile filter sealing-ring of long service life.

For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of automobile filter sealing-ring, formed by following composition proportion according to mass percent: rubber JSRN230S 20%, natural rubber 10%, carbon black 30.5%, chlorinatedpolyethylene 8%, tenderizer dibutyl ester 2.8%, promoting agent zinc oxide 1%, anti-aging agent 2.6%, vulcanization accelerator dicumyl peroxide 2.3%, magnesium oxide 2%, self-lubricating agent unsaturated fatty acids 1.5%, surplus is machine oil.

the advantage of automobile filter sealing-ring of the present invention is: the present invention is on the basis of lot of experiments, formulating of recipe to traditional seal ring for car filter has been carried out meticulous change, and adopted the production technique of two-stage mixing, thereby prepare in tensile strength, wear resistance, stability, the novel seal ring for car filter that the aspects such as tear strength all are significantly increased, the resistance toheat of product is promoted to 135 ℃ by 100 ℃ of standard, the ability of opposing machine oil and fuel oil corrosion strengthens greatly, and place at normal temperatures after 15 days and can reach self-lubricating effect from oozing out the wax-like protective layer of one deck, therefore extremely be convenient to assembling, also greatly extend work-ing life.

Embodiment

Below in conjunction with specific embodiment, the present invention is described in further details;

Embodiment 1:

A kind of automobile filter sealing-ring, formed by following composition proportion according to mass percent: rubber JSRN230S 20%, natural rubber 10%, carbon black 30.5%, chlorinatedpolyethylene 8%, tenderizer dibutyl ester 2.8%, promoting agent zinc oxide 1%, anti-aging agent 2.6%, vulcanization accelerator dicumyl peroxide 2.3%, magnesium oxide 2%, self-lubricating agent unsaturated fatty acids 1.5%, surplus is machine oil.

Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.

Claims

1. automobile filter sealing-ring, it is characterized in that, formed by following composition proportion according to mass percent: rubber JSRN230S 20%, natural rubber 10%, carbon black 30.5%, chlorinatedpolyethylene 8%, tenderizer dibutyl ester 2.8%, promoting agent zinc oxide 1%, anti-aging agent 2.6%, vulcanization accelerator dicumyl peroxide 2.3%, magnesium oxide 2%, self-lubricating agent unsaturated fatty acids 1.5%, surplus is machine oil.
