Problems solved by technology

[0004] In the prior art, a single mineral oil component is mostly used to produce electrical contact lubricating oil. This single mineral oil has poor fluidity and is easy to precipitate hydrogen; while aromatic hydrocarbons are good in resisting hydrogen precipitation, but the electric contact The contact lubricating oil has a short storage time and poor oxidation resistance. After a period of use, the electrical contact lubricating oil is prone to sludge, which greatly reduces the performance of the electrical contact lubricating oil.

Abstract

The invention discloses a preparation method of environment-friendly electric contact lubricating oil. The environment-friendly electric contact lubricating oil contains the following ingredients in parts by weight: 50-70 parts of base oil, 0.5-3 parts of a conductive agent, 0.5-1 part of hard lubricating oleic acid, 1.5-2.0 parts of methyl salicylate, 0.1-0.2 part of a metal deactivator, 0.01-0.02 part of an antioxidant and 0.5-1.5 parts of an antiwear agent, wherein the conductive agent is a compound of 50% of polypyrrole and 50% of fatty acid alkanolamide in mass ratio; the base oil is composed of a component I and a component II, the component I is dioctyl sebacate produced from castor oil, the component II is any one or combination of more than two of soybean oil, sunflower oil, sesame oil and linseed oil, in the base oil, mass percent of the component I is 55-75%, and the balance is the component II. The prepared lubricating oil is good in oil quality, high in oil ignition point,good in performance and good in conductivity and has moderate kinematic viscosity, high flash point and excellent oxidation resistance stability and anti-aging stability.

Description

technical field [0001] The invention relates to the field of manufacturing electrical contact auxiliary materials, in particular to a preparation method of an environmentally friendly electrical contact lubricating oil. Background technique [0002] Electrical contacts are the contact points in the circuit, which are widely used, such as household appliances, automobiles, electrical switches, various tuners, etc. Electrical contacts also require lubrication, and the performance requirements for lubricating oils continue to increase. The role of electrical contact lubrication lubricant is not only to reduce the wear between the contacts, but more importantly, to prevent electrical corrosion between the electrodes, so as to improve the accuracy of the electrical contact action and the comfort of the tuner. [0003] Electrical contact lubricating oil is a lubricating oil used in the protection of electric contacts for arc protection, anti-oxidation and anti-wear of weak curren...
