Problems solved by technology

Especially for some food-grade lubricants that require higher safety performance, there are few additives on the market that are both safe and have good performance
In some metal processing fields, the use of chlorine-containing extreme pressure antiwear agents is strictly restricted due to their corrosion and waste discharge problems
In metal drawing and forming lubricants, if molybdenum disulfide or other sulfur-containing compounds are used, subsequent cleaning of parts will become quite difficult

Abstract

The invention provides a sulfur and phosphorous-containing extreme pressure anti-wear reagent and a preparation method and application thereof. The product is an organic mixture of thiosulfate and phosphate. The product serving as a lubricating additive is applied to lubricating oil and has the functions of obviously improving the anti-wear extreme pressure performance and effectively protecting the mechanical equipment. The product is light in color, odourless and non-toxic, does not have adverse effect on the environment and is a high-performance environment-friendly lubricating oil extreme pressure anti-wear reagent.

Description

technical field [0001] The invention relates to a sulfur-phosphorous extreme pressure anti-wear agent, its preparation method and its application in lubricating oil. Background technique [0002] In the fields of lubricating oils, greases and metalworking fluids, the market increasingly demands high-performance, non-hazardous and eco-friendly extreme pressure and anti-wear additives. Especially for some food-grade lubricants that require higher safety performance, there are few additives on the market that are both safe and have good performance. In some metal processing fields, the use of chlorine-containing extreme pressure antiwear agents is strictly restricted because of their corrosion and waste discharge problems. In metal drawing and forming lubricants, if molybdenum disulfide or other sulfur-containing compounds are used, the subsequent cleaning of the parts will become quite difficult. [0003] Therefore, a main object of the present invention is to provide a lubr...
