Abstract

The invention discloses a synthesized lubricating oil containing pentasulfide and lard. According to a preparation method of the synthesized lubricating oil, diocty sebacate is taken as a base oil; America produced sulfur-containing extreme pressure agent poly pentasulfide TDPS532, lard CD-1, zinc dialkyldithiophosphate T202, and span-80 are added for uniform mixing so as to obtain the synthesized lubricating oil. The America produced sulfur-containing extreme pressure agent poly pentasulfide TDPS532 accounts for 0.05 to 0.35wt% of diocty sebacate, lard CD-1 accounts for 0.03 to 0.36wt% of diocty sebacate, zinc dialkyldithiophosphate T202 accounts for 0 to 0.30% of diocty sebacate, and span-80 accounts for 0 to 0.36wt% of diocty sebacate. The synthesized lubricating oil possesses extremely excellent extreme pressure and abrasion resistance; bearing capacity is as high as 2625.745N; wear value ranges from 0.23 to 0.4mm when loading is 392N, and wearing time is 60min, and wear value ranges from 0.32 to 0.41mm when loading is 441N, and wearing time is 30min. The synthesized lubricating oil can be used for combination with heavy duty vehicle gear oil, and can be used for metal processing oil, heavy duty industrial gear oil and middle duty industrial gear oil.

Description

A kind of ucon oil that contains pentasulfide and lard

Technical field

The present invention relates to a kind of automobile gear lubricating oil, particularly relate to a kind of ucon oil that contains pentasulfide and lard.

Background technology

Extreme pressure agent poly-pentasulfide TDPS532, the lard CD-1 of sulfur-bearing class, have fabulous extreme pressure and antiwear behavior, is mainly used in heavy duty industrial gear oil.Generate physics adsorption film and chemical reaction film, thereby improved its supporting capacity.Be mainly used in configuring heavy duty automobile gear oil, also can be used for heavy loading and medium duty industrial gear oil.

In the different monooctyl ester of synthetic oil sebacic acid, add pentasulfide TDPS532, lard CD-1, primary alkyl zinc dithiophosphate T202, proportioning is carried out in Si Ben-80, uses Artificial Neural Network computation optimization, and has carried out cumulative evidence.Owing to containing sulphur phosphoric, therefore supporting capacity is higher.

The different monooctyl ester of sebacic acid (Diocty sebacate) be by the different monooctyl ester of sebacic acid and 2-Ethylhexyl Alcohol esterification and colourless or micro-yellow oily liquid.20 DEG C time, the solubleness of these product in water is 0.02%, is dissolved in hydrocarbon, alcohol, ketone, ester, chlorocarbon class, is insoluble to di-alcohols.Volatility is lower, therefore can at higher temperature, use.There are good winter hardiness and good thermotolerance.Its viscosity is lower, is the more satisfactory softening agent of cold resistant cable material.Its shortcoming is easily to be extracted out by varsol, and easily migration, and water-fast extraction is also not ideal enough.Because consistency is poor, this oil product normal with phthalate use.Except for making polyvinyl chloride cable material, these product are also as the stationary liquid of the lubricating oil of jet engine and lubricating grease, gas-chromatography.These product are nontoxic.Be blended in feed and feed and raise big white mouse 19 months with the dosage of 200mg/kg, have no any intoxicating effect, also non-carcinogenesis.Can be used in packaging material for food.So check the bad defect of additive compatibility and can reach 98% with Poly alpha Olefins (PAO) synthetic air compressor oil shrinks with rubber, for the base oil of gear oil, aviation engine oil and engine, the highlyest adjustablely also can reach 98%.

Poly-pentasulfide TDPS532 is the product innovation of U.S. Chevron Phillips Chemical Company.Poly-pentasulfide molecular structural formula is: C ₁₂h ₂₅s ₅c ₁₂h ₂₅, non-corrosive sulfide; The pentasulfide TDPS532 of microcorrosion, table 2 is polysulphide physicochemical property,

Having both extreme pressure and wear-resistant two kinds of performances simultaneously.

Liquid lard oil CD-1: oiliness improver is by pigskin and lard is refining forms, yellow oily liquid, be soluble in ether solvent, in molecule, ester group is easy to metallic surface and forms oriented adsorption layer, improves lubricity, reduce the degree of wear, be applicable to the allotment of ROLLING OIL and metal cutting oil, also can be compound with emulsifying agent, configuration oil in water emulsion, semi-synthetic liquid, lard CD-1 gallops moral by Shanghai

Trade Co., Ltd provides.The physicochemical property of liquid lard oil CD-1 is in table 3.

Primary alkyl zinc dithiophosphate another name: ZDDP T202, there is good antioxygen, anti-corruption and wear-resistant effect, be applied to I. C. engine oil, hydraulic efficiency oil and industrial lubricant.

Anhydrous sorbitol fat vinegar, is commonly called as S p an (department originally), is the very important nonionogenic tenside of a class.Because they have the good surfactivity such as emulsification, dispersion,

And nontoxic nonirritant, thereby, be widely used in as emulsifying agent and dispersion agent etc. in the daily use chemicals industries such as makeup, food, medicine, and also there is application very widely in oil production, fiber process, leather processing, metal processing and pesticide producing, physico-chemical property coloured glaze clap look to brown h a shape liquid on a small quantity in Virahol, zellon, dimethylbenzene, oleum gossypii seminis, Dormant oils etc., H

Summary of the invention

The technical problem to be solved in the present invention is that a kind of have fabulous extreme pressure and antiwear behavior, high bearing capacity are provided.Meet a kind of ucon oil that contains pentasulfide and lard of configuration heavy duty automobile gear oil.

The technical scheme adopting is:

A kind of ucon oil that contains pentasulfide and lard, be taking the different monooctyl ester of sebacic acid as base oil, add extreme pressure agent poly-pentasulfide TDPS532, lard CD-1, primary alkyl zinc dithiophosphate T202, Si Ben-80 of U.S.'s product sulfur-bearing class to make through mixing.Its formula is:

The different monooctyl ester of sebacic acid is base oil, adds and accounts for the different monooctyl ester ester of sebacic acid weight percent:

Poly-pentasulfide TDPS532: be 0.05-0.35%

Lard CD-1: be 0.03%-0.36%

Primary alkyl zinc dithiophosphate T202: be 0-0.30 %

Si Ben-80: be 0-0.36%.

The present invention has fabulous extreme pressure and antiwear behavior, and the more much higher formula of supporting capacity is wherein up to 2765N more than can reaching 2265N, also can be used for heavy loading and medium duty industrial gear oil.
