Abstract
The invention relates to a lubricating oil extreme pressure antiwear agent, which is prepared from the following raw materials in part by weight: 20 to 30 parts of vulcanized iso-butylene, 20 to 30 parts of chlorinated paraffin, 2 to 5 parts of petroleum sulfonate, 1 to 3 parts of zinc dialkyl dithiophosphate, 10 to 20 parts of barium sulfonate, 5 to 10 parts of nano borate, and 5 to 10 parts of epoxy vegetable blended oil. The preparation method comprises: filling the raw materials into a reaction kettle, setting a temperature to be between 55 and 65 DEG C, and uniformly stirring for 24 hours till sticky liquid is formed. In the invention, various anticorrosion and antioxidant materials are adopted, the epoxy vegetable blended oil is added, and the formed compound has high corrosion resistance and oxidant resistance, the grease absorbability is increased, the film forming efficiency is increased, wear is relieved, and the antiwear agent is suitable for cold start of automobiles and is a brand new antiwear anent.
Description
Technical field
The invention belongs to the lubricating oil field, relate to the anti-wear agent of lubricating oil, especially a kind of extreme pressure antiwear agent for lubricant oil.
Background technology
Traditional oxidized petroleum waves extreme-pressure anti-friction additive very easily discharges when meeting water or friction generation high temperature and is with corrosive free chlorine, and corroding metal is especially serious to the corrosion of iron, also is difficult to suppress even add water sulfonate rust-preventive agent.By retrieval, find the following publication document relevant with present patent application:
1, the preparation technology (CN1077737) of the antirust extreme-pressure anti-friction additive of high-performance of a kind of addition of epoxy vegetable oil fat and sulfonate rust-preventive agent; in clorafin, add epoxidized vegetable oil fat to absorb free chlorine; thereby form protective film at friction surface; the performance antifriction function reduces and restrains its corrosion.This novel extreme-pressure anti-friction additive provided by the invention can be widely used in lubricating oil and the automobile gear oil, and excellent property is easy to use.
2, a kind of lubricating oil energy-saving antiwear agent (CN1611591), principal feature is that this anti-wear agent is made of anti-wear agent, extreme pressure agent, antioxidant preservative, rust-preventive agent, detergent-dispersant additive, defoamer etc., lubricating oil energy-saving antiwear agent anti-wear effect of the present invention is good, long service life and in lubricating oil additive capacity little, be widely used in modulating various hydrodynamic lubrications oil or improve the grade of general lubricating oil, as gasoline engine oil, diesel engine oil, gear oil, hydraulic efficiency oil, marine engine oil, air-tool oil and consume system's wet goods entirely.
3, a kind of preparation method of extreme pressure antiwear agent for lubricant oil (CN1453346) comprising: with organo-clay and C
4-C
24Carboxylic acid compound reacts under 100-160 ℃ in the presence of solvent, the Separation and Recovery product.The inventive method is utilized hydroxyl and the acid anhydrides or the carboxylic acid generation esterification at clay layer edge, make clay layer connect long carbochain, prepared extreme pressure anti-wear additives has dispersiveness and extreme pressure anti-wear preferably, elements such as sulfur-bearing, phosphorus, chlorine not, simple synthetic method, very wide development and application prospect are arranged, can be applicable to machining oil, ROLLING OIL, punching press wet goods industrial lubricant.
Above-mentioned three pieces of publication documents and present patent application have more different.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, the extreme pressure anti-wear additives that a kind of fastness to wear is strong, antioxidant effect is good is provided.
The object of the present invention is achieved like this:
A kind of extreme pressure antiwear agent for lubricant oil, it constitutes raw material and parts by weight are respectively:
The preparation method is:
Above-mentioned raw materials is put into reactor, design temperature 55-65 ℃, evenly stirred 2-4 hour, get final product up to forming thick liquid.
And described nano boric acid salt is nano boric acid sodium.
And described epoxy plant blend oil is the soybean plants mixed oil.
Advantage of the present invention and positively effect are:
1, this anti-wear agent adopts multiple corrosion-resistant, oxidation resistant material, and formed mixture has stronger corrosion resistance and resistance of oxidation.
2, this anti-wear agent has added the epoxy plant blend oil, has improved greasy adsorptivity and film forming efficiency, has reduced wearing and tearing, adapts to cold-starting automobile, is a kind of brand-new anti-wear agent.
Embodiment
Be described in detail embodiments of the invention below; Need to prove that present embodiment is narrative, is not determinate, can not limit protection scope of the present invention with this.
Embodiment 1:
A kind of extreme pressure antiwear agent for lubricant oil, it constitutes raw material and parts by weight are respectively:
The preparation method is:
Above-mentioned raw materials is put into reactor, and 60 ℃ of design temperatures evenly stirred 3 hours, got final product up to forming thick liquid.
Embodiment 2:
A kind of extreme pressure antiwear agent for lubricant oil, it constitutes raw material and parts by weight are respectively:
The preparation method is:
Above-mentioned raw materials is put into reactor, and 62 ℃ of design temperatures evenly stirred 4 hours, got final product up to forming thick liquid.
Embodiment 3:
A kind of extreme pressure antiwear agent for lubricant oil, it constitutes raw material and parts by weight are respectively:
The preparation method is:
Above-mentioned raw materials is put into reactor, and 58 ℃ of design temperatures evenly stirred 2.8 hours, got final product up to forming thick liquid.
Detected result:
By detecting, the wear-resistant coefficient of this anti-wear agent is 0.05-0.06.
By gasoline vehicle actual motion, after 10,000 kilometers, the lubricating oil gray scale is less, illustrates that resistance of oxidation obtains bigger raising.
