Novel extreme-pressure (EP) gear oil

Abstract

The invention discloses novel extreme-pressure (EP) gear oil, which comprises the following components in parts by weight: 30 to 45 parts of 100# mechanical oil, 40 to 50 parts of 38# cylinder oil, 0.1 to 1.0 part of BHT (butylated hydroxytoluene) antioxidant, 0.1 to 0.7 part of dibutyl phosphate, 1.0 to 2.0 parts of sulfur-phosphorous butyl octanol zinc salt, 0.2 to 0.8 part of alkenyl dibutyric acid, 0.2 to 0.9 part of demulsifying agent, 1.5 to 3.5 parts of dibenzyl disulphide, 10*10 to 6 parts of methyl silicone oil and 0.5 to 1.0 part of alkyl naphthalene. The EP gear oil has the advantages of the energy-conservation effect superior to the conventional product can be reached by fully reducing the friction; the EP gear oil has no toxin or harm to a human body and can reach the safety and environment protection requirements at high standards; the EP gear oil has good thermal oxidative stability and excellent rust protection and corrosion protection action; the service life of gears can be effectively prolonged; strong load or large load impact can be stood; the abrasion or the sintering of the gears can be prevented; and the EP gear oil is used for various industrial equipment working under the severe conditions of the heavy load or the impact load and high temperature.

Description

technical field [0001] The invention relates to a gear oil, in particular to a novel extreme pressure gear oil. Background technique [0002] Traditional circulating system lubricating oil usually uses volatile organic compounds such as trichlorethylene and tetrachlorethylene as the dilution solvent of the lubricant. This chlorine-containing dilution solvent has the advantages of non-flammability and fast volatilization rate. However, Trichlorethylene used in industry has great harm to human body and environment, especially the potential problems of destroying the ozone layer and causing diseases such as cancer. Contents of the invention [0003] The purpose of the present invention is to provide a new type of extreme pressure gear that is used for various industrial equipment working under severe conditions such as heavy load or impact load and high temperature, which is non-toxic and harmless to the human body, and can meet the requirements of safety and environmental pr...
