[0050] The above components are pulverized into particles with a diameter of 50 μm-3nm and mixed uniformly to become the product of the present invention.

[0051] Add 600ml of this product to the cylinder of a truck that has traveled 210,000 kilometers. The original cylindricity error of this cylinder is relatively large, among which cylinder 1: 0.15mm; cylinder 2: 0.14mm; cylinder 3: 0.15mm; cylinder 4: 0.13mm, cylinder 5: 0.00mm, cylinder 6: 0.01mm.

[0052] In the case of only replacing the piston ring and not doing any mechanical repairs on the cylinder, after adding the lubricating oil of the p...

Embodiment 3

[0054] According to the weight ratio, the following components are used:

[0055] Silicon fume Si 9%

[0056] Magnesium Oxide MgO 4.7%

[0057] Aluminum powder Al 61%

[0059] Nickel powder Ni 0.5%

[0060] Chromium oxide Cr 2 o 3 0.5%

[0061] Lithium nitride Li 3 N 5%

[0062] Gold powder Au 0.8%

[0063] Boron Powder B 15%

[0064] The above components are pulverized into particles with a diameter of 50 μm-3nm and mixed uniformly to become the product of the present invention.

[0065] Add 400ml of the product of the present invention into a worn out 1M 3 in the air compressor. Originally due to wear and tear of the air compressor, the supplementary oil volume was 2 kg / two days, and the start-up time was long, and the downtime was short, starting for 15 minutes and stopping for 5 minutes.

[0066] After using the product of the present invention to run for 8 days, the supplementary oil amount is 0.1 kg / two days, the st...

Abstract

A wear-proofing and repairing additives of lubricant oil comprises Silica dust1-10wt%; MgO 0.5-5wt%; aluminite powder 20-70wt%; titanic powder 0.5-5wt%; nickel powder 0.1-1wt%; chrome oxide 0.1-1wt%; lithium nitration 1-5wt%; gold powder 0.1-1wt%; and boracic powder 5-20wt%. All the said components are milled be particles of 50um-3nm uniformly. They can increase hardness of friction pair surface, improve wear resistance, repair defects, and prolong operating life. They can be used for steam cylinders, compressors, etc.

Description

Technical field: [0001] The invention relates to a lubricating oil additive and a preparation method thereof. In particular, the invention relates to an anti-wear repair additive for lubricating oil and a preparation method thereof. Background technique: [0002] Lubricating oil works in the harsh environment of friction and extrusion for a long time. Due to the influence of factors such as high relative speed on the surface of the friction pair, large load, and temperature difference changes, the lubricating oil often deteriorates and loses its lubricating effect, resulting in wear on the working surface. Affect the normal work of the parts, or even accidents. [0003] In order to prolong the life of the surface of the friction pair, additives composed of various components are currently added to the lubricating oil. For example, in order to solve the problem of lubricating oil deposits, calcium petroleum sulfonate can be added to the lubricating oil; in order to increase...
