Abstract
The present invention relates to a lubricant additive. It is a colloid solution which comprioses one of borate and este of several mixtures and is dispersed in lubricant by means of polyolefine emulsifier and whose grain size is below 0.5 micron, and has high extreme pressure property, good antiwear property, resisting to corrosion and resisting to oxidation, can be made into antiwear hydraulic oil and gear oil, etc.
Description
The present invention relates to a kind of antioxygen of lubricating oil, anti-corruption, wear preventive additive and preparation method thereof, be used to allocate antiwear hydraulic oil, the gear wet goods.
The quality of lubricating oil (agent) is decision machinery equipment serviceability and one of important factor that prolongs its work-ing life, and lubricating oil additive is the marrow of various senior lubricants (agent), can give the property that lubricating oil itself does not possess.As＜the lubricant tribo-chemistry 〉. the .1994 of Sinopec press introduced in 10 months.The inorganic borate additive in lubricating oil extreme pressure and the research of abrasion resistance start from the beginning of the sixties.1964 Van Der Veer (Vandeuveer) Wo Bisi (Voorbees) synthesized borate additive for lubricating oil.After, gold people such as (King) has also delivered their research work.The Industrial products that the end of the seventies occurred borate additive, as: the OLOA-9750 gear oil additive of Cheveron company.
The borate that common people are familiar with comprises some alkali metal compounds such as potassium borate, Sodium Tetraborate, metaboric acid and sodium metaborate, and wherein, preceding two kinds of chemical combination have the similar molecular structure of thing, and the structure of back two kinds of compounds is also similar, all contains B
3O
6 3-Ion belongs to the plane six-ring on this ionic structure.Borate generally all has crystal water, and with the crystal water different amts, molecular structure also changes.Its crystal water can be heated and take off, even but borate itself under very high temperature, can not decompose yet.United States Patent (USP) 3,313,727 at the stable an alkali metal salt dispersion liquid in the preparation lubricating oil, and wherein the alkali metal borate of aquation is to be enough to keep particle stabilized dispersive amount of borate and emulsifier mix.These particles it is said that size almost all is lower than 1 micron, and major part is lower than 0.5 micron.Suitable alkali metal borate is to have the sodium of 1-4 water of hydration and the metaborate and the tetraborate of potassium.Also can there be neutral dispersion agent in these components, for example the alkenyl succinimide of alkali amine.CN1175621A discloses the preparation method of superfine borate additive for lubricating oil, adopts the ultrasonic emulsification method, and process is comparatively complicated.
From the work of having delivered, as the inorganic borate (or mixture) of extreme-pressure anti-friction additive by its empirical formula of forming of following several reflections:

3The ratio of your number of motorcycle is about 1: 1～and 2.
Additive is glassy fine particle with boratory form, and particle dia is less than 1 μ m, and majority should be less than 0.51 μ m, and too thick particle can not form stable solid-oil dispersion system, and effect is played at the engaging friction interface effectively.
Another main component is the blended dispersion stabilizer in the boronic acid containing salt additives prescription.The main effect of dispersion agent is to guarantee that boratory particulate is suspended in the oil uniformly and stably, and guarantees that borate can not separated out in crystallization under the situation that has moisture to exist.This class dispersion agent should have two class materials, and the one, hydrophobic anion surfactant contains elements such as II family element and sulphur in its molecule, and another is hydrophobic nonionogenic tenside.
Hydrophobic nonionic surface active agent mainly comprises the derivative of succinyl amine, polymethacrylate or tetramethylolmethane.Wherein most widely used general with the succimide class.
Generally there are two kinds of methods in preparation borate oil dispersion system: polishing and double decomposition
Polishing is a kind of method that is relatively easy to for preparing borate oil dispersion system.Its shortcoming is the difficult less boratory dispersion system of granularity that obtains.This method is not contain crystal water or some amount crystal water mesoboric acid salt mixes with base oil by a certain percentage, grinds in mortar in the presence of dispersion agent or uses the ball grinder barreling, and mill with vibration mill vibration or colloidal mill.
Double decomposition is with B (OH)
3, NaOH or Na

3Reactant aqueous solution, products therefrom emulsification in containing the oil of dispersion agent, intensification is at last dewatered and is made the borate oil dispersion.Can obtain the less borate dispersion of granularity with this method, but dehydration operation is difficult, borate is curding out in dehydration easily.The preparation borate additive for lubricating oil is that borate is made the aqueous solution among United States Patent (USP) and the CN1175621A, under the effect of neutral sulfonated petro-leum of dispersion agent and succimide, be scattered in the oil then, generate the emulsive borate microparticulate borate additive for lubricating oil of heating-up section dehydration suspensoid then by vigorous stirring.
The composition and preparation method thereof that the purpose of this invention is to provide the lubricating oil additive of a kind of antioxygen, anti-rotten, wear-resistant oil bag molten salt and inorganic ester aqueous colloidal dispersion.
In order to overcome the not high shortcoming of succinyl amine thermostability, the present invention is dispersed into colloid as dispersion emulsifier with borate and boric acid ester emulsification with polyolefine toxilic acid poly-hydroxy, this emulsifying agent has Heat stability is good than succinyl amine, the emulsifying power advantages of higher.The technology that existing preparation borate oil dispersion is is cumbersome, and polishing needs barreling in ball grinder for a long time, and mills with vibration mill vibration or colloidal mill, and double decomposition need be made aqueous product, dehydration then.The present invention adopts and makes borate and boric acid ester mixture, to reduce its fusing point, is dispersed in more than fusing point in the oil, and generation colloidal solution need not dewatering process and brute force is milled.
Lubricating oil additive of the present invention by dispersion agent, help emulsion, base oil, inorganic salt or inorganic ester to form, wherein inorganic salt and inorganic ester by dispersion agent, help emulsion, base oil to coat to form less than the dispersoid below 0.5 micron, consist of by weight:
