Problems solved by technology

[0003] In the production of auto parts, extruded anti-wear agents are needed at any time, but the wear resistance of many extruded anti-wear agents is not very good, and after the anti-wear agents are used, the parts will rub against each other. There are many scratches, these scratches will bring great inconvenience to the processing and use of subsequent parts

Embodiment Construction

[0019] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific examples.

[0020] An extreme pressure antiwear agent, in terms of parts by mass, consists of the following components:

[0021] Silicon fume 1-10%

[0022] Magnesium Oxide 0.5-5%

[0023] Aluminum powder 20-70%

[0024] Phosphate 0.5-5%

[0025] Nickel powder 0.1-1%

[0026] Dibenzyl disulfide 0.1-1%

[0027] Molybdenum naphthenate 1-5%

[0028] Molybdenum disulfide 5-20%

[0029] When this invention is used, it needs to be used according to the following methods:

[0030] When using, firstly, the above-mentioned components need to be pulverized in turn, and screened with a 80-100 mesh screen. After the screening is completed, the powders of each component are evenly mixed, and then smeared on the surface of the parts to be used can be used directly;

Abstract

The invention provides an extreme-pressure antiwear additive, relating to the technical field of antiwear additives. The extreme-pressure antiwear additive is composed of the following components in percentage by mass: 1-10% of silicon powder, 0.5-5% of magnesium oxide, 20-70% of aluminum powder, 0.5-5% of phosphate, 0.1-1% of nickel powder, 0.1-1% of dibenzyl disulfide, 1-5% of molybdenum naphthenate and 5-20% of molybdenum disulfide. The extreme-pressure antiwear additive can increase the surface hardness of the part to enhance the wear resistance, and can also repair the generated abrasion defect to prolong the service life of the friction part.

Description

Technical field: [0001] The invention relates to the technical field of antiwear agents, in particular to an extreme pressure antiwear agent. Background technique: [0002] In boundary lubrication, when the metal surface only bears a moderate load, if there is an additive that can be adsorbed on the metal surface or wear violently with the metal surface, this additive is called an anti-wear additive. When the metal surface bears a high load, a large number of metal surfaces are in direct contact, generating a lot of heat, and the film formed by the anti-wear agent is also destroyed, which no longer protects the metal surface. For example, there is an additive that can interact with the metal surface. The chemical reaction forms a chemical reaction film, which acts as a lubricant, prevents the metal surface from being scratched, or even welded. Usually, this most severe boundary lubrication is called extreme pressure lubrication, and this additive is called extreme pressure a...
