Description
Technical field
The present invention relates to a kind of preparation method of rubber packing material, particularly a kind of rubber packing material and preparation method thereof of dimethyl ether resistant automobile fuel.
Background technology
Dme (DME) is the simplest ethers organic compound of a kind of molecular structure, only has C-H and C-O key in its molecule, and oxygen level is 34.8% of whole component, thus can Thorough combustion, do not analyse carbon, without raffinate.In addition, its calorific value is high, cetane value is lower than diesel oil, combustion noise is low, and wide material sources, can produce in a large number from raw materials such as coal, Sweet natural gas, coal-seam gas, biomass.Thus, the very big concern of countries in the world investigator is caused as a kind of desirable vapour clean fuel for vehicle, especially the prospect of the very good dimethyl ether fuel automobile in developed regions and country such as America and Europe, Japan and Korea S, carries out the R&D work of dimethyl ether fuel engine and automobile one after another.China was almost synchronous with the world in the research of dimethyl ether fuel motor car engine, and Shanghai Communications University just assume responsibility for the national project " research of novel low blowdown dimethyl ether fuel spray characteristics and flame mechanism " of China's first term about dimethyl ether fuel engine from 1997.Through the further investigation of more than ten years, achieve significant progress and significant achievement in this area.
Because DME is the lower molecular weight ethers organic compound that a kind of polarity, perviousness and volatility are stronger, solubilized or some polymer materials swelling, make its mechanical properties decrease, especially to the performance impact of the rubber packing materials such as traditional petroleum oil fuel fuel system of automobile viton, paracril and acrylate used more very.In addition, also wherein some other nonpolar compositions to be added as vapour dimethyl ether fuel for vehicle, as: lubrication, antiknock dope etc.So, vapour dimethyl ether fuel for vehicle should be that this just requires that the material of rubber seal products has the performances such as good swelling resistance, impermeabilisation and incompressible tension set for this special medium with polar organic compound dme for the main COMPLEX MIXED system again containing nonpolar chemical additive.Just because of this, cause people in the research of dme fuel system of automobile sealing article material, never have a satisfactory and desirable result.Up to the present seeming people also holds fully and other kind of rubber-like materials outside perfluoroelastomers material is used for the rubber accessory of engine, the especially rubber seal products of dme fuel system of automobile by confidence.
Perfluoroelastomers is the class elastomerics obtained by perfluoro methyl vinyl ether, tetrafluoroethylene and perfluorinated allyl ethers terpolymer.In chemical resistance, in the environment such as the ethers that general Viton cannot be suitable for, amino-complex, ketone, oxygenant, organic solvent, fuel, acid, alkali, perfluoroelastomers can demonstrate the stability of its brilliance, almost all has excellent tolerance to all chemical.But perfluoroelastomers is except price is very expensive, the resistance to low temperature that its chemical structure characteristic determines this elastomeric material is poor, and particularly process industrial art performance is poor, has used significant limitation as industrialization purposes.So people carry out the research work of this respect even to this day still as beforely.Also many reports are had in document, such as: Sorenson [JournalofEngineeringforGasTurbinesandPower, 2001,123 (7): 652-658] think that terpolymer EP rubber (EPDM) and perfluoroelastomers can tolerate the erosion of dme; [the TheSocietyofRubber1ndustry such as Hashimoto, 2005,78 (3): 111-118] then think that EPDM can not use completely, the tolerance performance of isoprene-isobutylene rubber (I1R) to DME is best, and paracril (NBR), silicon rubber (S1R) can use reluctantly; The people such as Li Genbao [XI AN JIAOTONG UNIVERSITY Subject Index, 2005,39 (3): 317-320] have also carried out the performance comparison test of dimethyl ether resistant fuel to multiple rubber material, result thinks that again trifluoropropyl siloxane material property is ideal; The people such as Wu Ning [Shanghai Communications University's journal, 2006,40 (8): 1257-1260] rubber seal prepared 10 kinds of elastomeric materials has carried out dimethyl ether resistant fuel simultaneous test, thinks the rubber seal swelling resistance better performances prepared with EPDM material; The result of study of Luan Liqun [coal gas and heating power, 2012,6 (32): 14-16] shows that ethylene-propylene rubber(EPR) and tetrafluoroethylene anti swelling in liquid phase dimethyl ether fuel is better.The research that above-mentioned document is reported is substantially all be based upon the exploration work on polymer matrix material simultaneous test basis, do not relate to the further investigation of rubber compounding and complete processing, so, the understanding that its result neither one is unified, and for Study and Development have industrial applications be worth dimethyl ether resistant automobile fuel rubber seal products there is certain limitation.
Therefore, by carrying out rubber compounding system and technology research, make full use of the performance advantage of different polymkeric substance in dme automobile fuel, adopt special composition and engineering technology the isoprene-isobutylene rubber of terpolymer EP rubber good for dimethyl ether resistant swelling property and permeability resistance excellence and swelling resistance, impermeabilisation and reinforcing good dispension polymerized poly resin organically to be combined, this will be a kind of effective ways developing dimethyl ether resistant automobile fuel sealing article elastomeric material.
