Abstract
The invention relates to high-temperature chain oil of mixed base oil, which comprises: (1) 50-80 percent of ester oil; (2) 20-50 percent of specific polyether base oil; and (3) 1.5-3.5 percent of antioxidant, 0-3 percent of antiwear agent and 0-1 percent of rust inhibitor. The viscosity of the high-temperature chain oil at 40 DEG C is 150-320cst. Therefore, the high-temperature chain oil of the invention has a high viscosity index and low coking tendency under high temperature conditions.
Description
Technical field
The present invention relates to a kind of lubricating oil, specifically, relate to a kind of composition that is applied to lubricated high temperature chain.
Technical background
Chain drive not only is suitable for using under the high pulling torque and the slow speed of revolution, and in corrodibility and wet environment, and use can both demonstrate superiority in the high speed transmission.The smooth running of chain and chain link nimbly and freely, the good lubrication effect that reduces to wear and tear and depend on the chain greasisng system, the bearing pin of chain and the normal operation that the gap between the sleeve guarantees good lubricating effect and chain will be injected regularly, quantitatively with resistant to elevated temperatures lubricating oil by the chain greasisng system.Along with developing rapidly of industries such as China's weaving, printing and dyeing, petrochemical industry, building materials and traffic, the transmission system working temperature of these equipment is more and more higher, and is also harsh day by day to the requirement of chain oils.
The high temperature service that industries such as weaving, plastics, building materials are used, chain moves under 180～260 ℃ condition usually.This moment, refined mineral oil can't satisfy service requirements, must use ucon oil to be base oil.The selected base oil of high-temperature chain oil has PAO (poly-alpha olefins), ester class oil and polyethers three major types at present.
Molecular structure and the refined mineral oil of PAO (poly-alpha olefins) are similar, belong to hydrocarbon polymer; Have than the better resistance to elevated temperatures of mineral oil, very high viscosity index and lower pour point, be fit to very much wide temperature range and use down.Synthetic to compare high-temperature behavior relatively poor but with other.U.S. Pat 5151205 reports, with PAO is base oil, add a spot of ester class oil and make solubilizing agent, polybutene with 2-4% is tackifier, the chain oils that is equipped with appropriate functional additive gained again has low vaporization losses and persistent lubricity, and under identical working conditions, but the mineral oil origin chain oils produces a large amount of cigarettes, and should in use almost smokelessly produce by prescription oil.
Compare with PAO, ester class oil has better supporting capacity.Can be divided into several types such as dibasic acid esters, polyol ester alcohol ester, multiple ester, aromatic esters again according to type of feed and molecular structure ester class oil.The viscosity temperature characteristic of dibasic acid esters oil and low-temperature performance (weighing with the pour point index) are similar with PAO, and resistance to elevated temperatures is better than PAO, and vaporization losses is very little under the hot conditions.Therefore the mixture of dibasic acid esters and PAO is used widely as complete synthesis engine oil base oil, but because dibasic acid esters oil has only low viscosity product usually, generally composite as the high-temperature chain oil base oil with other ester class oil.
The polyol ester that is used for lubricant base comprises trihydroxymethylpropanyl ester, pentaerythritol ester, bis(pentaerythritolester).Polyol ester has higher viscosity index, is generally more than 140; Than the loss of the lower high temperature evaporation of dibasic acid esters, high flash-point (greater than 300 ℃) uses low-molecular-weight fatty acid can obtain pour point less than-60 ℃ product.Polyol ester is used widely in L-HFDU anti-flame hydraulic fluid, aviation engine oil, wet goods field, high temperature grease basis.U.S. Pat 6436881 has been reported by C7,8,9,10 acid and isomery C9 acid (3,5,5 tri-methyl hexanoic acids) bis(pentaerythritolester) is done the research of the high-temperature chain oil of base oil, and compare with the performance of PAO/ ester class oil type high temperature viscosity, the result shows, dipentaerythritol type high-temperature chain oil has much better high-temperature behavior, and high-temperature coking amount and vaporization losses are little, and coking plate face also cleans very much.
Aromatic esters comprise trimellitate and pyromellitic ester, compare with dibasic acid esters and polyol ester, and viscosity index is relatively low, some product viscosity index only is about 70, but owing to contain phenyl ring in the molecule, therefore stronger oxidation stability is arranged, main in the past base oil as synthetic compressor oil.
Chinese patent 200810101780 has been reported a kind of ester type high temperature chain oil composition, wherein contain (1) 71～95% low viscosity ester class oil, (2) 0～10% high viscosity ester class oil, the polyisobutene of (3) 0～10% specified molecular weight, and (4) 1～5% oxidation inhibitor, 0～3% anti-wear agent and 0～1% rust-preventive agent.But owing to contain the high-viscosity compound ester, and this raw material all has very high acid number, causing at hot conditions lower chain oil has higher viscosity rising tendency.
Polyethers has good high temperature performance, very high viscosity index, and noncoking under high temperature, high pressure, has good lubricity, and can be easy to obtain various full-bodied polyethers as required, and polyethers is well suited for doing various lubricant bases.But because the flash-point of polyethers is relatively low, volatile quantity is bigger under the hot conditions.
Summary of the invention
According to the constructional feature of chain, small amounts product, greasy filth and carbon deposit that chain oils produces all can produce considerable influence to chain load; Because high-temperature chain oil moves under hot conditions for a long time, each magnitude of recruitment is few, and chain oils forms film in the metallic surface, causes that oil product is more volatile, drippage and oxidation.How to reduce the vaporization losses of chain oils, the viscosity that suppresses oil product increases and guarantee that the adhesivity that suits is the key of exploitation chain oils.
The present invention relates to a kind of is the high-temperature chain oil of base oil with ester class oil, comprising (1) 50～80% ester class oil, (2) 20～50% special polyether base oils, (3) 1.5～3.5% oxidation inhibitor, 0～3% anti-wear agent and 0～1% rust-preventive agent.40 ℃ of viscosity of the high-temperature chain oil that the present invention relates to are 150～320cst, and have viscosity rising tendency features of smaller under hot conditions.
Ester class oil can be one or more miscellanys in trihydroxymethylpropanyl ester, pentaerythritol ester, bis(pentaerythritolester), the trimellitate.Preferably pentaerythritol ester, trimellitate or its miscellany; 40 ℃ of viscosity of selected ester class oil are 50～350cst.Viscosity is crossed low meeting and is increased vaporization losses, the too high perviousness and the jet performance that can influence chain oils of viscosity.The polyethers base oil is 40 ℃ of water soluble polyethers that viscosity is 100～300cSt, and viscosity is crossed low meeting and increased processed oil vaporization losses; The too high anti-deposition properties that can influence processed oil of viscosity.
Additive therefor of the present invention comprises 1.5～3.5% oxidation inhibitor, be preferably alkyl diphenylamine, alkyl phenyl alpha-naphthylamine, two 2, two or more miscellanys in 6-ditertbutylparacresol, the hydrogenated quinoline polymer, optimizing consumption is 1～3%, can take into account the antioxidant effect of ester class oil and polyether oil like this, effectively avoid oxidation inhibitor deposition under the hot conditions.
The used anti-wear agent of the present invention is phosphate amine salt salt biology or tritolyl phosphate, and rust-preventive agent is methyl benzotriazole or methyl benzotriazole derivative copper corrosion inhibitor, and above-mentioned two kinds of additive amount are balance carefully, otherwise can cause oxidation stability sharply to descend.
