Problems solved by technology

[0003] In response to VGP regulations, major foreign lubricating oil companies have launched biodegradable products one after another. Typical biodegradable industrial gear oils include Castrol's Biotrans 220, Total CARTER BIO 220, Shell's ShellNaturelle 150, 220, 320, etc. ;Traditional gear oils use mineral oil and additives with high sulfur and chlorine content. During use, due to temperature reasons, a large amount of toxic gases are generated, corroding equipment, and damaging the environment. General degradable gear oils have certain biodegradable properties. resistance, but the degradation performance is not strong, and it does not have excellent working indicators, and cannot adapt to various working environments

Abstract

The invention relates to the technical field of lubricating oil, in particular to biodegradable industrial gear oil and a preparation method thereof. The biodegradable industrial gear oil is prepared from the following raw materials of extreme-pressure antiwear additive, phosphorous -containing antiwear additive, metal deactivator, oxidation and corrosion inhibitor, anti-rust agent and base oil. The biodegradable industrial gear oil has the advantages that the oxidizing stability and the seizure and biting resisting property are good, the viscosity index is higher, and the flash point and pour point are higher; the biodegradable industrial gear oil is suitable for more complicated use working condition and temperature change, the equipment can be well lubricated, the influence to equipment by water is avoided, the oil replacement cycle is prolonged, and the additional loss caused by frequent oil replacement is avoided; by adopting the biodegradable base oil and the environment-friendly additives, the biodegrading rate is higher, and the environment-friendly property is guaranteed on the basis of meeting the working requirements.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, and relates to a biodegradable industrial gear oil and a preparation method thereof. Background technique [0002] With the progress of society and the increasingly stringent environmental protection laws and regulations around the world, people pay more and more attention to the research and development of biodegradable lubricating oils including industrial gear oils. In March 2013, it was mentioned in the latest revision of the US Environmental Protection Agency's VGP (vessel general permit) that after December 19, 2013, in US waters (in a broad sense, it refers to any place within 3 miles of the US coast) , the oil used in equipment that may be in contact with seawater on commercial ships larger than 79 feet must be biodegradable products, unless it is technically infeasible, equipment involving the use of biodegradable oil in VGP includes adjustable pitch propellers, paddle wheel prop...
