Abstract
The invention relates to an antiwear additive of lubricating oil, which is characterized by comprising 1%-5% of dispersant, 5%-20% of nanoscale metal powder and the balance of base oil, wherein the nanoscale metal powder comprises copper oxide powder, magnesium powder, chromium powder and boron powder; and the dispersant is polyisobutene-bis-succinimide or polyisobutene-multi-succinimide. A preparation method is simple and practical; in addition, the prepared additive has low cost, can play good abrasion resistant effect on various base oils and has good repairing function but no corrosion effect inside a machine.
Description
(1) technical field
The present invention relates to a kind of additive for wear resistance of lubricating oil, particularly a kind of manufacture method of additive for wear resistance of lubricating oil.
(2) background technology
Along with developing rapidly and the renewal of mechanical means of engine technology, to the demands for higher performance of lubricating oil, and the use of wear preventive additive can improve the over-all properties of lubricating oil greatly.But the wear preventive additive effect of current domestic production is bad, and external high-quality additive for wear resistance of lubricating oil price is relatively more expensive.
(3) summary of the invention
The objective of the invention is to solve the problem that exists in the above-mentioned technology, provide a kind of engine and machinery equipment are had significantly wear-resistant, anti-attrition, repairing effect, mechanical inside is not had corrosive nature, the lubricating oil anti-wear additive that cost is low.
Technical scheme of the present invention:
A kind of additive for wear resistance of lubricating oil is characterized in that: be made up of base oil, dispersion agent, nanometre metal powder; Nanometre metal powder comprises cupric oxide powder, magnesium powder, chromium powder and boron powder.Dispersion agent is the two butyryl imines of polyisobutene or many butyryl of polyisobutene imines; The weight percent of various components is that dispersion agent 1-5%, nanometre metal powder 5-20%, surplus are base oil.
A kind of above-mentioned additive for wear resistance of lubricating oil, it is characterized in that: base oil is to subtract any two kinds of components in four lines, HVI500, HVI150,150BS, 10 centistokes, the 5 centistoke base oils or the combination of three kinds of components, and the weight quota ratio of each component is 1: 1 or 1: 1: 1.
A kind of above-mentioned additive for wear resistance of lubricating oil is characterized in that: the weight quota ratio of each component of nanometre metal powder is 1.5-6%, magnesium powder 1-5%, chromium powder 0.5-4%, boron powder 2-4% for cupric oxide powder.
A kind of above-mentioned additive for wear resistance of lubricating oil is characterized in that: the nanometre metal powder mean particle size is 30-40nm.
A kind of manufacture method of above-mentioned additive for wear resistance of lubricating oil is characterized in that: base oil, dispersion agent, nanometre metal powder are mixed, heat and controlled temperature in 45-60 ℃, stirred 90-180 minute, promptly get product after the filtration.
Advantage of the present invention: this manufacture method is simple and practical, and the additive cost that makes is low, all can play good anti-wear effect to each class lubricating oil, good wear and repairing effect, and mechanical inside do not had corrosive nature.
