Abstract
A nm-class additive of rare-earth hydroxide for lubricating oil is prepared from water-soluble inorganic rare-earth salt, disperser, surfactant, promoter, basic oil and hydroxide, and features 10-50 nm of granularity, high dispersion in lubricating oil, and low pollution and poison. It can be used as excellent extreme-pressure antiwear additive for lubricating oil.
Description
The invention discloses a kind of nano size rare earth hydroxide lubricant oil additive and preparation method thereof.
Rare earth element and compound thereof are widely used in metallurgy, chemical industry, electronics and nuclear industry and numerous areas such as medicine and agricultural owing to having many unique chemical and physicals.In recent years, the application of rare earth compound in tribology also paid close attention to by people day by day.In the inorganic rare earth compound with rare earth fluorine being most widely used in lubricating grease, U.S.4,507,214,4,946,607,4,946,608 and CN1,032549A, 1,032,550A discloses rare earth fluoride and had good lubricity in lubricating grease.Rare earth oxide also has report as lubricant, but rare earth hydrate yet there are no report as lubricating oil and grease additive.U.S.S.R.679,618 and U.S.684,711 disclose dialkyl group phosphorus (phosphine) acid rare earth title complex has good corrosion resistance and wear resistance.U.S.S.R.1,373,687 to have narrated amido sulfuric acid rare earth title complex be the wear-resistant of well behaved lubricating grease, marproofing additive.The inorganic rare earth compound is accepted by people as solid lubricant, because its dispersed very poor in lubricating oil, thereby limited its widespread use in lubricating oil.
The object of the present invention is to provide a kind of nano size rare earth hydroxide lubricant oil additive and preparation method thereof, it has good dispersiveness, extreme pressure and abrasion resistance in lubricating oil.
Additive of the present invention is made up of water-solubility rare-earth inorganic salt, dispersion agent, tensio-active agent, promotor, base oil, oxyhydroxide.
Nano size rare earth hydroxide lubricant oil additive by: water-solubility rare-earth inorganic salt 10～20, dispersion agent 10～30, tensio-active agent 0.3～5, promotor 10～30, base oil 40～60, oxyhydroxide 3～8 (weight percentage) are formed.
Inorganic salt of rare earth is rare earth chloride, rare earth nitrate or perchloric acid rare earth, and rare earth is one or more a mixture of lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium.
Dispersion agent is one or more mixtures of the two succimides of polyisobutene mono butonediimide, polyisobutene, calcium mahogany sulfonate, petrolic magnesium sulfonate.
Tensio-active agent is Si Ben-20, Si Ben-80, Tween-40, Tween-60, preferably selects Si Ben-80 for use.
Promotor is one or more mixture of water, methyl alcohol, ethanol, propyl alcohol, butanols.
(40 ℃ of viscosity are 28.8-35.2mm to base oil for the refining base oil of mesodialyte cerul
2/ s).
Oxyhydroxide is sodium hydroxide or potassium hydroxide.
Lubricating oil additive preparation method of the present invention is:
10～20wt.% is soluble in water with the water-soluble inorganic rare-earth salts, with 10～30 parts of wt.% of dispersion agent, tensio-active agent 0.3～5wt.%, promotor 10～30wt.%, base oil 40-60wt.%, 1 part of benzene (is 1 part with above-mentioned total amount) is mixed with above-mentioned solution, in stirred in water bath half an hour, slow dropping sodium or potassium hydroxide 3～8wt.% solution, at stirred in water bath 5-8 hour, add 3-4 part benzene so that filter.Remove materials such as benzene, water under reduced pressure.
Nano size rare earth hydroxide of the present invention is the very effective lubricating oil extreme pressure of a class, wear preventive additive.Its addition as lubricating oil additive is 0.1wt%～15wt%.
The present invention compares with prior art, has substantive distinguishing features: the particle size of nano size rare earth hydroxide has good extreme pressure and abrasion resistance in 10～50 nanometers in lubricating oil, has low toxicity, the low pollution.
In order to understand the present invention better, describe by example.
Example 1 is soluble in water with the 1.86g Lanthanum trichloride, again 3g polyisobutene mono butonediimide, 0.1g calcium mahogany sulfonate, 0.3g Si Ben-80,10ml methyl alcohol, 7g base oil are mixed with above-mentioned solution, add 10ml benzene, in stirred in water bath half an hour, slowly drip the 0.6g sodium hydroxide solution, stirred in water bath 8 hours.Add 60ml benzene so that filter.Filtrate decompression is steamed materials such as removing toluene, water.
Example 2 is soluble in water with the 2.22g praseodymium nitrate, again the two succimides of 3.5g polyisobutene, 0.1 petrolic magnesium sulfonate, 0.3g Si Ben-80,5g base oil are mixed with above-mentioned solution, add 15ml benzene, in stirred in water bath half an hour, slowly drip the 0.6g sodium hydroxide solution, stirred in water bath 7 hours.Add 50ml benzene so that filter.Filtrate decompression is steamed materials such as removing toluene, water.
Example 3 is soluble in water with 2.35g perchloric acid gadolinium, again the two succimides of 3.5g polyisobutene, 0.1 petrolic magnesium sulfonate, 0.3g Si Ben-80,8g base oil are mixed with above-mentioned solution, add 15ml benzene, in stirred in water bath half an hour, slowly drip the 0.84g potassium hydroxide solution, stirred in water bath 5 hours.Add 50ml benzene so that filter.Filtrate decompression is steamed volatile matter such as removing toluene, water.
Example 4 reaction conditionss are with example 1, and the lanthanum in the Lanthanum trichloride is replaced with in cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, the lutetium one or more respectively, can obtain the relevant nanometer rare earth hydrate.
With four-ball friction and wear test machine extreme pressure and the abrasion resistance of nanometer lanthanum hydroxide in whiteruss of preparation in the example 1 estimated.For the ease of contrast, extreme pressure and the abrasion resistance of commercial additive-zinc dialkyl dithiophosphate (ZDDP) in whiteruss also estimated.Extreme pressure property is to carry out according to GB3142-82.The operational condition of wear-resistant experiment is: load 392N, and time 30min, rotating speed 1450rpm after experiment finishes, measures the wear scar diameter (WSD) of steel ball, and gained the results are shown in table 1.Table 1 extreme pressure (P
BBe worth) and the abrasion resistance evaluation result
