Description
Technical field
The invention belongs to petrochemical industry, be specifically related to a kind of antiwear additive and preparation method thereof.
Background technology
The electromotor of automobile industry is proposed various new technique to adapt to new Abgasgesetz, and the change that the lubricating oil also exigence closely bound up with electromotor is relevant adapts to the requirement of this increasingly stringent, reaches the target of energy-saving and emission-reduction. This just requires that oil body is lower, and greasy property is better, this necessarily limits the application of the additives such as tradition sulfur phosphorus chlorine.
Boric acid extreme pressure agent is a kind of novel extreme pressure agent, and its extreme pressure property, wear resistance, thermal oxidation stability energy, high-temperature corrosion-resistance performance and airtight performance are better than some other type extreme pressure agent. The colloidal dispersions of Borate Ep Additive substantially a kind of kollag. Under surface of friction pair charge effect, the charged particle in dispersion liquid is adsorbed on surface, forms viscosity thick film. Borate Ep Additive is alkalescence calcium mahogany sulfonate, boric acid, sodium hydroxide is raw material, prepares through boronation reaction and metathesis reaction. The feature of Borate Ep Additive is that extreme pressure property is good, but water is more sensitive. It is broadly divided into inorganic borate and organic boric acid ester. Inorganic borate additive mainly includes some metallic compounds such as potassium borate, sodium borate, potassium metaborate and sodium metaborate. Their form is glassy fine particle, and particle diameter is less than 1 μm, most less than 0.5 μm. Borate is a kind of multi-functional lube oil additive, there is the extreme-pressure anti-wear Wear vesistance of excellence, good thermal oxidation stability, rust resistance and corrosion resistance and seal compatibility, tender more superior than sulfur system, phosphorus system additive, nontoxic odorless, free from environmental pollution, must apply in industrial gear oil, two-stroke gasoline engine oil, automotive gear oil, and there is obvious energy-saving effect. Boratory shortcoming is that oil-soluble is poor, can not form stable solid oil dispersion system, and can not effectively enter frictional interface and work in oil. Therefore, current commodity borate additive for lubricating oil relies primarily on the substantial amounts of surfactant of addition to ensure that boratory microgranule is uniformly suspended within oil, and ensures that borate will not crystallization in the presence of moisture. Additionally, another big shortcoming of boric acid extreme pressure agent is exactly hydrolytic resistance difference, once moisture content is higher in gasoline, may result in it and dissolve, do not reach the effect of lubrication.
Summary of the invention
Goal of the invention: present invention aims to the deficiencies in the prior art, it is provided that a kind of antiwear additive.
Another object of the present invention is to the preparation method that above-mentioned antiwear additive is provided.
Technical scheme: in order to reach foregoing invention purpose, the present invention is specifically achieved like this: a kind of antiwear additive, component including following parts by weight: the Calcium pyroborate of 5～15 parts, the deionized water of 40～60 parts, the emulsifying agent SP-80 of 6～12 parts, the paraffin of 5～15 parts, the industrial naptha of 80～100 parts and 40～60 parts of 150N base oils.
Preferably, it is made up of the component of following parts by weight: the Calcium pyroborate of 5 parts, the deionized water of 50 parts, the emulsifying agent SP-80 of 9 parts, the paraffin of 10 parts, the industrial naptha of 90 parts and 50 parts of 150N base oils.
Wherein, described paraffin is semi-refined paraffin wax.
The method preparing any of the above-described described antiwear additive, comprises the following steps:
(1) Calcium pyroborate and deionized water are heated to 40 degree, stir 1～2 hour;
(2) add emulsifying agent SP-80 and keep 40 degree, continue 2～3 hours;
(3) heating paraffin wax is to molten condition, incorporates in industrial naptha, and stirring is to transparent;
(4) step (2) and (3) gained are mixed, be to slowly warm up to 100 degree, carry out evacuation dehydration after keeping 30～40 minutes, be completely exhausted out to moisture;
(5) add 150N base oil, stir 20～30 minutes, be continuously heating to 145～150 degree and slough solvent naphtha and get final product.
Beneficial effect: the present invention is compared with conventional art, not sulfur-bearing phosphorus chlorine additive, effectively control pollution during gasoline combustion, simultaneously by microemulsion method to accompanying hydrochlorate granularity to reform, the process reformed completes the surface to Calcium pyroborate and carries out hydrophobic oleophilic oil process, thus obtaining a kind of hydrolytic resistance, the antiwear additive that oil soluble ability is good. Whole preparation method is scientific and reasonable, it is not necessary to a large amount of energy consumptions can complete.
