Universal fully-synthetic nonferrous metal cutting fluid and preparation method thereof

Abstract

The invention discloses a universal fully-synthetic nonferrous metal cutting fluid and a preparation method thereof. The cutting fluid comprises the following components in percentage by weight: 3-6%of polyalkylene glycol, 7-15% of polyester, 5-10% of polyether ester, 3-8% of non-ferrous metal corrosion inhibitor, 7-15% of boric acid ester, 2-5% of isopropanolamine, 8-12% of triethanolamine, 1-3%of special amine, 0.5-2% of organic molybdenum, 3-5% of alcohol ether carboxylic acid, 1-2% of preservative and the balance of water. The production process is simple, heating and pressurizing are not needed, and the influence on the environment is small; the product provided by the invention is good in extreme pressure lubricating property; the product is wide in applicable material range and does not go bad easily; the service life is long, and the discharge of waste liquid is reduced.

Description

Technical field: [0001] The invention belongs to the technical field of metal cutting fluid, and particularly relates to a metal working fluid for non-ferrous metal cutting, machining, forming and other processes. Background technique: [0002] Cutting fluid is an auxiliary medium used to cool and lubricate tools and workpieces during metal removal. Cutting fluid is usually scientifically compounded by a variety of super-functional additives. [0003] With the rapid development of the machinery industry, especially the implementation of the National Industry 4.0 strategy in recent years, various new materials and new processes have emerged, and the existing ordinary metalworking fluids have been unable to meet the increasingly complex machining requirements, especially for The processing of non-ferrous metal materials lacks a general-purpose fully synthetic non-ferrous cutting fluid.

Problems solved by technology

[0003] With the rapid development of the machinery industry, especially the implementation of the national industry 4.0 strategy in recent years, various new materials and new processes continue to appear, the existing common metalworking fluids can no longer meet the increasingly complex machining requirements, especially for The processing of non-ferrous metal materials lacks a general-purpose fully synthetic non-ferrous cutting fluid

[0004] At present, the cutting fluids used in non-ferrous metal processing in the market are generally emulsified or microemulsified products. These products generally use mineral oil as the base lubricant. In the process of metal processing, this type of base lubricant is easily affected by various external factors. It is very easy to breed bacteria and cause the overall cutting fluid to be corrupted and deteriorated. Frequent liquid changes are required, resulting in difficult discharge and high waste liquid treatment costs. The diluents of such emulsified or microemulsified cutting fluids are all milky white. When in use, it covers the workpiece and the working table of the machine tool, which greatly affects the observation of the processing surface of the workpiece; the formula components of this type of emulsified or microemulsified cutting fluid have a certain effect on the rust prevention of ferrous metals, but they are not effective for non-ferrous metals. The corrosion inhibition performance is poor, and the range of applicable materials is limited. Users often need to choose different cutting fluid products for different non-ferrous metals, which leads to an increase in the cost of use.
