Problems solved by technology

[0003] At present, cutting fluids are mainly divided into oil-based cutting fluids and water-based cutting fluids. During the use of oil-based cutting fluids, the oil-based cutting fluids pollute the environment, are flammable, and cool slowly. In addition, organic substances are used in the cleaning process, which is harmful to the human body. Serious hazards; compared with oil-based cutting fluid, water-based cutting fluid has excellent cooling and cleaning performance, low cost, and no pollution, but water-based cutting fluid has poor lubricity and wear resistance, and will generate high The heat makes the tool unable to complete the cutting; the cutting process is severely worn, the cutting efficiency is not high, the tool and the machined surface are damaged, and the service life of the tool is seriously affected

Abstract

The invention provides a metal cutting fluid which comprises the following components in parts by mass: 6-7 parts of rust inhibitor, 15-20 parts of lubricant, 0.05-0.15 part of anti-hard-water agent, 3-4 parts of antiwear additive, 0.2-0.5 part of preservative, 0.5-2 parts of lubricating additive and 50-70 parts of water. The invention also provides a preparation method of the metal cutting fluid, which comprises the following step: sequentially mixing the raw materials to obtain the metal cutting fluid. The metal cutting fluid provided by the invention can greatly lower the friction factor of the friction pair surface, enhances the lubricating properties of the cutting fluid, and effectively prevents the adhesion abrasion on the friction pair surface. The metal cutting fluid has the advantages of simple preparation steps and low environmental pollution.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a metal cutting fluid and a preparation method thereof. Background technique [0002] Cutting fluid is a liquid used to lubricate and cool cutting tools and workpieces during metal cutting and grinding. It has certain cooling, lubricating, rust-proof and cleaning properties. With the technological upgrading and remodeling of China's manufacturing industry, it is increasingly difficult to improve product quality and processing efficiency, especially the increase in imported equipment, which makes the cost of imported cutting fluid continue to increase. [0003] At present, cutting fluids are mainly divided into oil-based cutting fluids and water-based cutting fluids. During the use of oil-based cutting fluids, the oil-based cutting fluids pollute the environment, are flammable, and cool slowly. In addition, organic substances are used in the cleaning process, which is harmful to t...
