1. a kind of automobile anti-corrosive rubber sealing ring, which is characterized in that be composed of the following components in parts by weight: rubber alloy: 60 parts, activating agent: 5-10 parts, chemical protector: 3-5 parts, vulcanizing agent: 0.5-2 parts, neoprene 2.5-3.5 Part, carbon black: 30-70 parts, mica: 10-20 parts, plasticizer: 10-25 parts, antiscorching agent: 0.1-0.5 parts, stearic acid : 0.1-0.5 parts.

Technical field

The present invention relates to a kind of rubber seal more particularly to a kind of automobile anti-corrosive rubber sealing rings.

Background technique

The circular cowling that rubber seal is made of one or several parts is fixed between the labyrinth that formation is narrow in gap The barrier of gap or elasticity, plays barrier and sealing function.Have plenty of to realize that liquid seals, some is then to realize gas The occasion of sealing, liquid sealing is again complex with the sealing of oil.Such as make on the components such as cylinder, piston on car engine Rubber seal will not only realize that obstruction seals act on, simultaneously as the medium sealed is all fuel oil or lubrication Oil, thus rubber seal must also oil resistant, some also needs high temperature resistant, can guarantee service life.

And oil resistant rubber sealing ring in the prior art is mainly the product of fluorubber system, because its rubber raw materials itself contain Inert fluorine element, so fuel resistance is preferable.But the higher cost of fluorubber, such as fluororubber compounded rubber price are up to every Kilograms 150 yuan.

Rubber and plastic alloy be it is a kind of with nitrile rubber for main substrate, part polyvinyl chloride is added and carries out effectively modified material Material, from the point of view of studying angle to high molecular material, by polyvinyl chloride (PVC) macromolecular to nitrile rubber (NBR) long-chain The closing of upper double bond assigns a series of superior characteristics of rubber and plastic alloy: 1, with the excellent Hou Laohua of resistance to day and ozone-resistant Effect, improves the heat aging property of nitrile rubber significantly；2, the excellent oil resistance of nitrile rubber is remained, and With excellent solvent resistant and chemical corrosion resistance.But the process industrial art performance of rubber and plastic alloy is poor, this also gives rubber alloy It is widely used and promotes, bring certain difficulty.

Summary of the invention

In view of the deficienciess of the prior art, the technical problem to be solved by the invention is to provide a kind of mechanical property and Process industrial art performance is more preferable and corrosion resistant rubber seal.

In order to solve the above technical problems, the technical solution used in the present invention is: a kind of automobile anti-corrosive rubber seals Circle, is composed of the following components in parts by weight: rubber alloy: 60 parts, activating agent: 5-10 parts, chemical protector: 3-5 Part, vulcanizing agent: 0.5-2 parts, 2.5-3.5 parts of neoprene, carbon black: 30-70 parts, mica: 10-20 parts, plasticizer : 10-25 parts, antiscorching agent: 0.1-0.5 parts, stearic acid: 0.1-0.5 parts.

The advantages of automobile anti-corrosive rubber sealing ring of the present invention, is: by the present invention in that being helped with the functionality of specific rubber Agent improves the processing performance of sizing material, using environment-friendly type compounding agent, solves flying upward for dust, reduces its toxic side effect and right The pollution of environment, so that the equilibrium problem of comprehensive performance be made to be addressed.
