Problems solved by technology

However, when the service life of the processing fluid becomes longer, with the evaporation of water during processing, more Ca will be enriched. 2+ , Mg 2+ , thus forming a vicious circle, which cannot really solve the problem fundamentally
In addition, when softening the dilution water, adding too much softener will cause too much foam in the cutting fluid, and at the same time cause pitting corrosion on the surface of the workpiece and the machine tool, while adding too little will not achieve softening effect

Abstract

The invention provides hard-water-resisting semi-synthetic metal processing fluid and a preparation method thereof. The hard-water-resisting semi-synthetic metal processing fluid is prepared from thefollowing components in parts by weight: 25 to 60 parts of basic oil, 3 to 20 parts of emulsifier, 3 to 20 parts of antirust agent, 2 to 6 parts of corrosion inhibitor, 5 to 30 parts of alkali value storage agent and 8 to 40 parts of water. The hard-water-resisting semi-synthetic metal processing fluid provided by the invention has the advantages of good hard water stability and excellent antirustperformance, safe and odorless working environment and no irritation on human body skin and respiratory tracts.

Description

technical field [0001] The invention belongs to the field of metal working fluids, in particular to a semi-synthetic metal working fluid with high hard water stability and high hard water rust resistance. Background technique [0002] Metalworking fluid refers to the lubricating cooling medium used in the metalworking process, and is an important supporting material in the metalworking process. Metalworking fluid has the functions of lubrication, cooling, rust prevention and cleaning, etc., which can effectively prolong the service life of tools, prevent metal parts and machine tools from rusting, and take away the heat generated during processing, and effectively remove chips and dust on the surface of parts and tools , thereby improving processing quality and increasing production efficiency. [0003] During the use of metalworking fluids, due to the enrichment effect such as water evaporation, the water hardness of the machining fluid system will gradually increase, and ...
