Abstract
The present invention discloses a nanometer rare earth fluoride lubricant oil additive and a preparation method thereof. The nanometer rare earth fluoride lubricant oil additive is composed of water-soluble rare earth inorganic salt, a dispersing agent, a surface active agent, a promotion agent, base oil and sodium fluoride. The nanometer rare earth fluoride particle size of the present invention is 10 to 50 nanometers, the problem of rare earth fluoride dispersion in lubricant oil is successfully solved, and the nanometer rare earth fluoride lubricant oil additive is a lubricant oil extreme pressure anti-wear additive with good performance.
Description
The invention discloses a kind of nano size rare earth fluoride lubricant oil additive and preparation method thereof.
Rare earth fluorine has obtained widespread use in lubricating grease, U.S.4, and 507,214,4,946,607,4,946,608 disclose rare earth fluoride has good lubricity in lubricating grease.At CN 1,032549A, 1,032, among the 550A, rare earth fluorine is by being applied in the railway lubricant film forming paste of success, and obtained extraordinary lubricant effect.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 lubricating oil additive and preparation method thereof, it has good dispersiveness, extreme pressure and abrasion resistance in lubricating oil.
The present invention is made up of water-solubility rare-earth inorganic salt, dispersion agent, tensio-active agent, promotor, base oil, Sodium Fluoride.
Nano size rare earth fluoride lubricant oil additive by: water-solubility rare-earth inorganic salt 10～20, dispersion agent 10～30, tensio-active agent 0.1～5, promotor 10～30, base oil 40～60, Sodium Fluoride 2～5 (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 in lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, the lutetium.
Dispersion agent is one or more in the two succimides of polyisobutene mono butonediimide, polyisobutene, calcium mahogany sulfonate, the petrolic magnesium sulfonate.
Tensio-active agent is one or more of Si Ben-20, Si Ben-80, Tween-40, Tween-60.
Promotor is one or more mixture of water, methyl alcohol, ethanol, propyl alcohol, butanols, amylalcohol, hexanol, octanol.
(40 ℃ of viscosity are 28.8-35.2mm to base oil for the refining base oil of mesodialyte cerul
2/ s).
Its preparation method is as follows:
10～20wt.% is soluble in water with the water-soluble inorganic rare-earth salts, and dispersion agent 10～30wt.%, tensio-active agent 0.1～5wt.%, promotor 10～30wt.%, mesodialyte cerul are made with extra care base oil, and (40 ℃ of viscosity are 28.8-35.2mm
2/ s) 40～60wt.% mixed 0.6 part of benzene (is 1 part with above-mentioned total amount) with above-mentioned solution, in stirred in water bath half an hour, slowly drip the aqueous solution of 2～5wt.% Sodium Fluoride, stirred in water bath 5～10 hours.Remove materials such as benzene, water under reduced pressure.
The nano size rare earth fluoride that institute of the present invention synthetic itrogenous organic substance is modified is the very effective lubricating oil extreme pressure of a class, wear preventive additive.Its addition as lubricating oil additive is 0.1wt%～8wt%.
In order to understand the present invention better, describe by example.
Example 1 is soluble in water with the 1.86g Lanthanum trichloride, again 2g polyisobutene mono butonediimide, 0.2g calcium mahogany sulfonate 0.3g Si Ben-80,7g base oil are mixed with above-mentioned solution, add 10ml benzene, in stirred in water bath half an hour, slowly drip the aqueous solution of 1.1g Sodium Fluoride, stirred in water bath 7 hours.Add the benzene of 50ml so that filter.Filtrate decompression is steamed volatile matter such as removing benzene, water.
Example 2 is soluble in water with the 2.22g samaric nitrate, again the two succimides of 3g polyisobutene, 0.1g calcium mahogany sulfonate, 0.3g Si Ben-80,10ml methyl alcohol, 7g base oil are mixed with above-mentioned solution, add 14ml benzene, in stirred in water bath half an hour, slowly drip the 1.1g Fluorinse, stirred in water bath 9 hours.Add the benzene of 50ml so that filter.Filtrate decompression is steamed volatile matter such as removing benzene, water.
Example 3 is soluble in water with 2.35g perchloric acid erbium, again the two succimides of 2.1g polyisobutene, 0.2g petrolic magnesium sulfonate, 0.3g Si Ben-80,6g base oil are mixed with above-mentioned solution, add 15ml benzene, in stirred in water bath half an hour, slowly drip the aqueous solution of 1.7g Sodium Fluoride, stirred in water bath 8 hours.Add the benzene of 50ml so that filter.Filtrate decompression is steamed volatile matter such as removing benzene, water.
Example 4 reaction conditionss replace with cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium with example 1 respectively with the lanthanum in the Lanthanum trichloride, can obtain corresponding nano size rare earth fluoride.
Last non seizure load and the abrasion resistance of nanometer lanthanum fluoride prepared in the example 1 in whiteruss estimated with four-ball friction and wear test machine.For the ease of contrast, last non seizure load and the resistance to abrasion of zinc dialkyl dithiophosphate (ZDDP) in whiteruss also measured.The operational condition of wear-resistant experiment is: load 392N, experimental period 30min, rotating speed 1450rpm.After experiment finishes, measure the wear scar diameter (WSD) of steel ball, the results are shown in Table 1.
By above-mentioned experimental result as can be seen, this type of nano size rare earth fluoride has good extreme pressure property and wear resistance as lubricating oil additive, is lubricating oil extreme pressure, wear preventive additive that a class has wide application prospect.Table 1 last non seizure load (P
