Abstract
The invention relates to a biodiesel-resistant acrylate rubber composition. The biodiesel-resistant acrylate rubber composition consists of acrylic rubber, silicone rubber, an accelerator NA-22, an accelerator DM, high-abrasion-resistance carbon black, white carbon black, silicone oil, paradimethoxybenzene, vinyl triethoxysilane, an ethylene-methacrylate copolymer, dibutoxy ethyl ester phthalate, dibutoxy ethyoxyl ethyl ester adipate and 2,5-dimethyl-2,5-ditert-butylperoxyhexane. According to the biodiesel-resistant crylate rubber composition disclosed by the invention, the biodiesel resistance of the acrylate rubber is improved by selecting silicon rubber. After a 48-hour oil resistant test, the biodiesel-resistant acrylate rubber composition does not have obvious swelling; moreover, the other performances of the rubber are not changed obviously, and the oil-resistant effect is good.
Description
Technical field
The present invention relates to rubber technology field, particularly a kind of acrylate rubber composition of resistance to biofuel.
Background technology
In aerospace industry, automotive industry, machinofacture, oil production, oil refining and other industrial production, need the rubber item using in a large number in fuel oil, lubricating oil, hydraulic pressure wet goods oils, yet all there is the deficiency of oil resistant aspect in the rubber item of producing by standard technology.If rubber item in use and oils medium Long Term Contact, oils can be penetrated into rubber inside makes it produce swelling, causes the intensity of rubber and other mechanical properties to reduce.
In recent years, be subject to the impact of crude oil price, environmental protection pressure, Biodiesel is in widespread attention.Biofuel is a kind of fatty acid methyl ester compound, by vegetables oil or animal tallow and alcohol compound, under catalyzer exists, carries out esterification generation.Compare with conventional diesel, have good environmental protection characteristic, in biofuel, sulphur content is low, makes sulfurous gas and sulfide emission low, and does not contain the aromatic series alkane to environment, is the petroleum diesel surrogate of high-quality.Along with the exhaustion of world petroleum resource, the recyclability of biofuel and good incendivity have reduced the dependence of people to oil.
Acrylic elastomer be by acrylate normally alkyl ester be principal monomer, with the class elastomerics forming with the monomer copolymerization that the active group of crosslinking reaction can be provided on a small quantity.In synthetic rubber, the volume of production and marketing of acrylic elastomer is less, but because it is more inexpensive than silicon rubber, silicon rubber, more superior than paracril heat resistant oils and oxygen aging resistance, therefore have certain industrial application value, acrylic elastomer as a kind of oil resisting rubber be widely used in that rubber oil sea, O shape circle, pad and sebific duct etc. are high temperature resistant, in the goods of heat resistant oils.As the reproducibility diesel oil fuel that can replace petroleum diesel, the market demand of biofuel is in continuous increase, this just means that the rubber item being in contact with it is also more and more stricter on performance requriements, yet the rubber item that standard technology is produced all exists the deficiency of resistance to bio-fuel-oil aspect.
Summary of the invention
Object of the present invention is mainly a kind of new acrylic elastomer of exploitation, further improve its resistance to biofuel performance, when guaranteeing to add some auxiliary agent to improve resistance to biofuel performance, the unobvious change of other performance or change occur in allowed band simultaneously, guarantee oil resistant effect and other performance requriements of sizing material.
By the practice of the data of searching and lot of experiments, determine, in acrylic elastomer and use proper amount of silicon rubber, its oil resistance is greatly improved, and along with the increase of acrylic elastomer consumption, and progressively improve by the oil-proofness of glue.But because acrylic elastomer is strong polar rubber, and silicon rubber is non-polar rubber, and both consistencies are poor; By adding solubilizing agent, can solve the difficult problem that silicon rubber, acrylic elastomer are difficult for blend.In co-mixing system, add the dispersion effect that ethylene-methyl acrylate multipolymer improves two kinds of glue.Add phthalate as softening agent, the resistance to biofuel performance of Reinforced Rubber, and on not impact of the sulfuration of rubber, can make goods there is good outward appearance and physical and mechanical properties.
Technical scheme of the present invention is as follows:
, its component and mass fraction are as follows:
Acrylic elastomer and silicon rubber add up to 60 parts.
By adopting acrylic elastomer and silicon rubber use and under the acting in conjunction of the auxiliary agents such as phthalate, the resistance to biofuel performance of acrylic elastomer has had further raising, after experience 48h oil resistant test, do not produce obvious swelling, and other performances of rubber obviously do not change, and oil resistant is respond well.
The raising of the resistance to biofuel performance of acrylic elastomer has also improved the use value of rubber simultaneously, for acrylic elastomer material and goods thereof in automotive field, the field of petrochemical industry important in inhibiting that can better play a role, safety control and the work-ing life of having improved goods.
Embodiment
The acrylic elastomer of resistance to biofuel embodiment: in mass fraction
By starting material and consumption in listed formula, carry out common mixed refining process:
1, rubber, starting material weigh
2, one section of banburying-mono-section opens refining-lower sheet
3, two sections of banburying-bis-section open refining-lower sheet
4, sulfide film
5, by standard, cut style
6. test detection
To use silicon rubber to improve the test-results of the resistance to biofuel performance of acrylic elastomer below:
By the summary to above-mentioned test, the resistance to biofuel performance of selecting silicon rubber to improve acrylic elastomer is significantly improved.
The acrylic elastomer of resistance to bio-fuel-oil that the present invention proposes, by have been described in detail above, person skilled obviously can be within not departing from content of the present invention, spirit and scope to formula as herein described and preparation method changes or suitably change realize the technology of the present invention with combination.Special needs to be pointed out is, all similar replacements and change apparent to those skilled in the artly, they are deemed to be included in spirit of the present invention, scope and content.
