Description
Technical field
The present invention relates to the sebific duct technical field, particularly the formula of rubber hose of butyronitrile PVC high-concentration ozone resistant.
Background technology
The high-concentration ozone resistant sebific duct mainly refers to the tank filler sebific duct that uses in automobile, this sebific duct is extruded by full glue and constituted, and material is a butyronitrile PVC rubber.The sebific duct of anti-ozone of automobile is worked in gasoline or ethanol petrol medium, often puts to be exposed to be subjected to solar radiation in the air, because the effect of UV sunlight can make the sebific duct surface produce be full of cracks, makes the sebific duct leakage of oil cisco unity malfunction that breaks, and these all are that ozone causes.According to the elastomeric material characteristic, not only oil resistant but also the good rubber of anti-ozone had viton, chlorohydrin rubber, butyronitrile PVC rubber because preceding two kinds of rubber are all somewhat expensive, so in, what adopt mostly in the low-grade automobile is butyronitrile PVC rubber.Elastomeric material itself is the ozone proof principal element of influence, and the formulating of recipe quality also has certain effect.A kind of sebific duct of tank filler preferably of present domestic use, can only satisfy the requirement of the ozone concn of anti-50pphm, along with the automobile fast development, trolley part safety, environmental requirement are become more and more higher, the tank filler sebific duct of part vehicle will satisfy the requirement of 200pphm concentration of ozone, therefore be the requirement of the high-concentration ozone resistant that improves rubber tube of oil filling port of vehicle oil tank under the situation that does not change elastomeric material, this has become is badly in need of in the sebific duct industry solving and many people still fail a technical problem effectively solving in research.
Summary of the invention
Purpose of the present invention just provides the prescription of the good butyronitrile PVC rubber of a kind of high-concentration ozone resistant, is applied to rubber tube of oil filling port of vehicle oil tank, has overcome the deficiency of currently available products, improves the work-ing life of rubber tube of oil filling port of vehicle oil tank.
The component of the formula of rubber hose of high-concentration ozone resistant of the present invention and mass fraction prescription are as follows:
100 parts of butyronitrile PVC rubber (latex coprecipitation method, Russia produces),
Fast carbon black (N550) 20～40 parts that extrude,
20～40 parts of carbon black MT N990,
5～15 parts of dioctyl esters (DOP),
5～15 parts of light magnesium oxides (MgO),
4～10 parts in zinc oxide,
1.5～3 parts of dibenzothiazyl disulfides (DM),
1.5～3 parts of 1,4 bis tert butyl peroxy isopropyl benzenes (BIPB),
1.5～2.5 parts of iso-cyanuric acid triallyl esters (TAIC-70),
0.2～0.4 part in sulphur,
Gu grand 3～5 parts of horse,
1～3 part of stearic acid
1～2 part of Microcrystalline Wax,
1～2 part of N-sec.-propyl-N '-diphenyl-para-phenylene diamine (4010Na)
2,2,4-trimethylammonium-1,1～2 part of 2-dihydro quinoline woods polymer (RD).
Wherein the main raw material(s) source is:
Butyronitrile PVC rubber-Russia produces, and middleization Internaional, Inc sells
Sunlight chemical industry company limited of BIPB-Shanghai section
Sunlight chemical industry company limited of TAIC-70-Shanghai section
Connection rubber main office in middle particle pyrolysis method carbon black (MT N990)-Beijing
Major ingredient butyronitrile PVC rubber of the present invention, butyronitrile PVC rubber are paracril and polyvinyl chloride (PVC) and with making, and paracril and polyvinyl chloride are also with two kinds of methods of latex coprecipitation method and mechanical mixing are arranged.The latex coprecipitation method be meant with special polyvinyl chloride emulsion and acrylonitrile-butadiene rubber latex mix, condensation, drying form.Little, easy to process by the blend physical and mechanical properties fluctuation that the latex coprecipitation method makes.Mechanical mixing is meant and adopts mill or Banbury mixer that polyvinyl chloride and paracril are carried out the blended method.This method can arbitrarily be adjusted the proportioning of paracril and polyvinyl chloride according to service requirements, but paracril and polyvinyl chloride carry out fusion under differing temps, the ozone ageing performance of gained cross-linked rubber is discrepant, the high blended rubber of acrylonitrile content is with the rising of fusion temperature, the improvement of its ozone resistance is obvious more, for fear of the fluctuation that causes because of technological factor ozone resistance, so that the present invention's employing is latex coprecipitation method butyronitrile PVC.
The selection of vulcanization system is extremely important, passes logical method and be crosslinked between the paracril, and paracril and polyvinyl chloride do not carry out crosslinked, and this method is unfavorable for improving the ozone of its resisting high-concentration.The present invention adopts BIPB-altax-MgO-ZnO Co-crosslinked System, can make and carry out co-crosslinking between paracril and the polyvinyl chloride, the resistance toheat of co-crosslinking sizing material and compression set better performances have formed co-crosslinking between two kinds of polymkeric substance, thereby have also improved its ozone proof ability.
The reinforcement of butyronitrile PVC rubber self is poor, therefore in sizing material, must cooperate the strengthening agent that is fit to, strengthening agent in the conventional formulation is only with the fast carbon black that extrudes, tensile strength height, expressing technique are good, in the present invention's prescription, select for use MT N990 and the fast carbon black that extrudes also to use, it is big that its particle diameter ratio extrudes carbon black soon, it is little that texture ratio extrudes carbon black soon, can give sizing material enough elasticity, therefore select for use MT N990 carbon black and its also with guaranteeing the tensile strength height, when expressing technique is good, can reduces compression set again, improve elasticity.
Effect of the present invention, owing to adopt latex coprecipitation method butyronitrile PVC and co-crosslinking vulcanization system, can obtain best material property, tensile strength is greater than 12.0MPa, tensile yield is greater than 300%, 120 ℃ * 70h compression forever diminishes in 40%, in the physical and mechanical properties that guarantees material, good anti-gasoline and ethanol petrol performance are arranged, make its anti-ozone ability bring up to 200pphm, compare, produce significantly difference with traditional product from 50pphm, exceed four times of traditional products, improved the work-ing life of high-concentration ozone resistant sebific duct greatly.Expressing technique is stable.Thereby can satisfy the requirement of rubber tube of oil filling port of vehicle oil tank high-concentration ozone resistant better.
