Abstract
A disclosed fluororubber valve-rod oil seal is composed of the following raw materials in parts by weight: 93-100 parts of fluororubber F 26, 5-7 parts of polyvinyl butyral, 2-3 parts of beta-hydroxyalkylamide, 1-2 parts of sodium fluosilicate, 2-3 parts of zinc borate, 1-2 parts of zinc oxide, 5-8 parts of polyamide wax micro-powder, 2-3 parts of sodium silicate, 5-7 parts of diisodecyl phthalate, 1-2 parts of pentaerythritol, 3-4 parts of poly(4-methyl-1-pentene), 1-2 parts of zinc n-butylxanthate, 1-2 parts of 2-benzimidazolethiol and 20-26 parts of a compound filling material. The fluororubber valve-rod oil seal provided by the invention is capable of preventing lubricating oil of an automobile lubricating system from externally leakaging or seepaging, helps to guarantee sealing effect and is improved in service life.
Description
Technical field
The present invention relates generally to auto parts machinery field, relates in particular to a kind of viton stem oil seal.
Background technology
Viton is ageing-resistant, heat-resisting, and oil resistant is almost applicable to all lubricating oil, oil fuel, gasoline, containing being difficult for sclerosis in the oil of extreme-pressure additive, but winter hardiness, high temperature abrasion resistance are poor, and permanent compression set is larger, is applicable to temperature-20～250 ℃.Be mainly used in high temperature resistant oil sealing as engine oil seal etc., therefore add auxiliary agent to improve the over-all properties of viton, can strengthen the use range of viton.
Summary of the invention
The object of the invention is just to provide a kind of viton stem oil seal.
The present invention is achieved by the following technical solutions:
A kind of viton stem oil seal, it is comprised of the raw material of following weight parts:
Viton F2693-100, polyvinyl butyral acetal 5-7, beta-hydroxy alkylamide 2-3, Sodium Silicofluoride 1-2, zinc borate 2-3, zinc oxide 1-2, polyamide wax micropowder 5-8, flower bulb alkali 2-3, Di Iso Decyl Phthalate 5-7, tetramethylolmethane 1-2, poly--4-methyl-1-pentene 3-4, zinc n butylxanthate 1-2,2-mercaptobenzimidazole 1-2, compounded mix 20-26;
Described compounded mix is comprised of the raw material of following weight parts:
Black earth 32-40, lithium bentonite 6-10, brominated Polystyrene 2-4, sodium silicoaluminate 2-3, naphthenic oil 1-2, Zirconium tetrafluoride 0.1-0.4, boric acid 0.6-1;
Above-mentioned black earth is mixed with lithium bentonite, at 600-700 ℃, calcine 1-2 hour, after cooling discharging, mix with Zirconium tetrafluoride, pulverize, add brominated Polystyrene, naphthenic oil, 200-300 rev/min of dispersed with stirring 5-6 minute, adds the each raw material of residue, seasoning after stirring, obtains described compounded mix.
A preparation method for viton stem oil seal, comprises the following steps:
Above-mentioned viton F26 is mixed with poly--4-methyl-1-pentene and put into Banbury mixer and carry out banburying, temperature 105-110 ℃, the time is 1-3min; Add the each raw material except zinc n butylxanthate, 2-mercaptobenzimidazole, continue banburying 8-12 minute, when temperature reaches 95-100 ℃, start discharge, after discharge, park cooling 24-30 hour; In input mill, add the each raw material of residue, thin-pass 6-8 is all over obtaining described viton stem oil seal.
Advantage of the present invention is:
Viton stem oil seal of the present invention can prevent that the lubricating oil of vehicle lubricating system from leaking or seepage, guarantees sealing effectiveness, the work-ing life of having improved stem oil seal.
