Embodiment 1

[0012] An anti-wear additive for lubricating oil is composed of base oil, dispersant, and nano-scale metal powder; the base oil is a mixture of 10 centistokes and 150BS, and its weight ratio is 1:1. The dispersant is polyisobutylene polybutyrimide, and the nanoscale metal powder includes copper oxide powder, magnesium powder, chromium powder and boron powder, and its weight ratio is 85% of base oil; dispersant is 3%; copper oxide powder is 3% ; Magnesium powder 3.5%; Chromium powder is 2.5%, boron powder is 3%. The above-mentioned base oil, dispersant, copper oxide powder, magnesium powder, chromium powder, and boron powder are measured according to the weight of each component, and then mixed Evenly, heat and control the temperature at 50-60°C, stir for 120 minutes, and filter to obtain the product, which has the following properties after testing:

[0013] 1. Increase the extreme pressure and anti-wear index of ordinary engine lubricating oil by 25%, and reduce the diameter ...

Embodiment 2

[0017] An anti-wear additive for lubricating oil is composed of base oil, dispersant, and nano-scale metal powder; the base oil is a mixture of 10 centistokes and 150BS and HVI500, and its weight ratio is 1:1:1. The dispersant is polyisobutylene polybutyrimide, and the nanoscale metal powder includes copper oxide powder, magnesium powder, chromium powder and boron powder, and its weight ratio is 79.5% of base oil; dispersant is 3%; copper oxide powder is 6% ; Magnesium powder 4%; Chromium powder is 3.5%, boron powder is 4%. The above-mentioned base oil, dispersant, copper oxide powder, magnesium powder, chromium powder, and boron powder are measured according to the weight of each component, and then mixed Evenly, heat and control the temperature at 55-65°C, stir for 150 minutes, and filter to obtain the product, which has the following properties after testing:

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 [0001] The invention relates to an anti-wear additive for lubricating oil, in particular to a method for manufacturing the anti-wear additive for lubricating oil. (2) Background technology [0002] With the rapid development of engine technology and the renewal of mechanical equipment, higher requirements are placed on the performance of lubricating oil, and the use of anti-wear additives can greatly improve the overall performance of lubricating oil. However, the current domestically produced anti-wear additives are not effective, and foreign high-quality lubricating oil anti-wear additives are relatively expensive. (3) Contents of the invention [0003] The purpose of the present invention is to solve the problems in the above-mentioned technologies, and provide a low-cost lubricating oil wear-resistant additive that has obvious anti-wear, wear-reducing, and repair functions for engines and machinery, has no corrosive effect on the interior of the mac...
