Embodiment approach 1

[0031] Implementation mode one: Take 20 parts of triethanolamine and 8 parts of diglycolamine by weight, mix well, heat to 80°C, add 6 parts of triazine triamino acid, 6 parts of undecyl dicarboxylic acid, and 2 parts of potassium hydroxide in proportion, Stir the reaction for 30 minutes until it becomes a uniform transparent thick liquid. Take 6 parts of sorbitan oleate by weight, heat to 50°C, add 2 parts of non-ferrous metal corrosion inhibitor in proportion, stir well until it becomes a uniform transparent liquid, and then add it to the thick liquid synthesized in the first step , continue to stir evenly. Among them, the non-ferrous metal corrosion inhibitor is one or a mixture of tolyl benzotriazole, benzotriazole, phosphoric acid ester and phosphonic acid ester.

Abstract

The invention relates to a synthetic multiple-effect lubricant additive and a preparation method thereof and in particular relates to a fully-synthetic multiple-effect lubricant additive which does not contain S and Cl and takes a metal processing lubricant as a main product. The fully-synthetic multiple-effect lubricant additive is a mixture containing glycerol single ricinoleate, a carboxylic acid synthetic ester lubricant, iso-tridecanol polyoxyethylene ether, an antirust agent, amine phosphate, a non-ferrous metal corrosion inhibitor and a carboxyl hexyl-2-cyclohexene-1-octadeca-carbonic acid. The fully-synthetic multiple-effect lubricant additive has the advantages of good wear resistance, good anti-rust performance, good synergy and environmental friendliness. The fully-synthetic multiple-effect lubricant additive is applicable to blending emulsified oil, micro-emulsifying liquid, fully-synthetic metal working fluid, metal rolling liquid and metal molding working fluid as well as lubricating oil products such as water-based fire-resistant hydraulic oil.

Description

technical field [0001] The invention relates to a synthetic multi-effect lubricating additive and a preparation method thereof, in particular to a synthetic multi-effect lubricating additive which does not contain sulfur and chlorine and is used to produce the main product of metal processing lubricants and a preparation method thereof. Background technique [0002] Since the 21st century, in order to meet the requirements of modern processing and green manufacturing, the requirements for metalworking fluids have become higher and higher. The selection of lubricating functional additives with excellent performance is the key to improving the comprehensive performance of metal processing lubricants. Chlorine-containing additives and sulfides are traditional anti-wear extreme pressure additives. The most commonly used chlorine-containing additives are chlorinated paraffins. In 1985, the toxicity test of chlorinated paraffins conducted by the International Virus Organization ...
