Description

A kind of many lip rubber seal
【Technical field】
The present invention relates to the technical field of mulit-lip seal ring, particularly a kind of technical field of many lip rubber seal.
【Background technology】
Many lip rubber seal are the compounded rubber seal with two or more sealing lip, generally as the machine of oil sealing fat Tool original paper, many lip rubber seal isolate the part that lubrication is needed in drive disk assembly with part of exerting oneself, and are unlikely to allow lubricating oil Seepage.Many lip rubber seal rings for seal are good, and service life is long, heat-resisting, wear-resistant, ageing-resistant, simple in construction, quick detachable, inspection Test facility, but many lip rubber seal often not easy-formation when vulcanizing processing, cause defect rate very high.
【The content of the invention】
The purpose of the present invention is exactly to solve the problems of the prior art, a kind of many lip rubber seal of proposition, good airproof performance, Both there are traditional many good sealings of lip rubber seal, heat-resisting, wear-resistant, ageing-resistant performance makes many lip rubber close again Seal is easily molded when vulcanizing processing, reduces substandard products defect.
To achieve the above object, the present invention proposes a kind of many lip rubber seal, including following components and each component Mass ratio is：
Preferably, the activated zinc oxide AZO-805 is from the nanoscale high-active zinc oxide for originating from Taiwan, damp process Manufacture, its characteristic is fine white crystalline powder, water insoluble, is soluble in acid, the aqueous solution of ammonium salt.Specific surface area is big, activity Degree is high, makes an addition in rubber, plus sulphur speed is constant, and can keep good physics, mechanical performance, improves product quality and stably Spend and reduce cost.It is the activating agent, thermal conducting agent, hot solvent for preparing nitrile rubber, the vulcanization of rubber can be promoted.
Preferably, the stearic acid SA1840 selects the stearic acid SA1840 that Hangzhou oil and fat chemical is produced, stearic acid SA1840 can be functioned as follows in preparation：1. softening and the favourable carbon black of 2. exterior lubricant of plasticization 3., white carbon and The abundant diffusion 4. of zinc oxide and the reaction of zinc oxide or alkaline accelerator can promote its activity, or main vulcanization to promote to help Agent, can play a part of the second accelerator, can accelerate hardening, and 5. significantly reduce compound viscosity, improve processing performance, can be notable Improve the plasticity of sizing material.
Preferably, No. 80 microwaxes select No. 80 microwaxes that Suzhou company of all kinds of matters U.S. produces, microwax is in rubber Glue product surface formation protective filmy layer, contact of the isolation ozone with rubber, so as to serve the effect of ozone-resistant cracking.
Preferably, first age resistor is antioxidant 4010NA, also known as N- isopropyls-N ＇-diphenyl-para-phenylene diamine, point Dissipate property good, on vulcanizing no influence, originate from Shandong Shang Shun companies.
Preferably, second age resistor is antioxidant MB, also known as 2- mercaptobenzoimidazoles, when can reduce the vulcanization of rubber Discoloration.
Preferably, the tasteless DCP of vulcanizing agent, also known as two-(t-butylperoxyisopropyl) benzene, vulcanization, crosslinking effect Really good, the rubber product performance produced is stable.
Preferably, graphite powder AO of the graphite powder from Japan NICHIDEN, is that rubber has good high temperature resistant And anti-wear performance.
Preferably, the carbon black 550, as reinforcing agent, is increased the wearability of rubber, carried from Cabot carbon black 550 Tensile strength, the tearing strength of high rubber.
Preferably, the diatomite selects the diatomite MW27 of product company of the U.S. one, strengthen the rigidity and intensity of rubber, Improve heat resistance, wearability and the ageing resistace of rubber seal.
Preferably, the spray carbon black processing characteristics is good, vulcanization glue elasticity is big, heat is low, deformation is small, cryogenic property Good, stress at definite elongation is high.
Preferably, the inner pattern releasing agent applicable LTM-A can improve the presentation quality of rubber, product surface light, molding Easily, to properties of product without any harmful effect, while being produced in sulfidation without pernicious gas, nothing pollution-free to mould Corrosion, reduces hand labor intensity, extends mould physical life.
Preferably, the molybdenum disulfide good dispersion, is not bonded, rubber wear-resisting performance is improved.
Preferably, the white carbon selects the white carbon 532EP of PPG companies of the U.S., reinforcing agent is used as.
Preferably, the activating agent is PEG4000, lubricant and cooling agent are used as.
Preferably, many lip rubber seal include following components and the mass ratio of each component is：
Preferably, many lip rubber seal include following components and the mass ratio of each component is：
Preferably, many lip rubber seal include following components and the mass ratio of each component is：
Beneficial effects of the present invention：Compared with prior art, its remarkable advantage is a kind of many lip rubbers of the invention to the present invention Glue sealing ring, good airproof performance, both with traditional good sealing of many lip rubber seal, heat-resisting, wear-resistant, ageing-resistant property Can, many lip rubber seal is easily molded when vulcanizing processing again, reduce substandard products defect.
