Problems solved by technology

Emulsified cutting fluid is a kind of water-based cutting fluid. At present, most products have the following problems: 1. The scope of application is narrow. A corrosion inhibitor can only have a slow-release effect on one metal. It is applied to cast iron, steel, aluminum, and magnesium. For unused metal materials such as copper and copper, products with different formulas need to be used respectively, so that one product can only be used for one or two kinds of metal materials, and the versatility is very low; 2. Since the emulsified cut

Abstract

The invention relates to a self-bacteriostasis general emulsion cutting fluid and a preparing method thereof. The components of the emulsion cutting fluid includes, by weight, 50-70 parts of base oils, 7-25 parts of non-ionic surface active agents, 4-10 parts of anion surface active agents, 3-10 parts of monoisopropanolamines, 3-5 parts of compound corrosion inhibitors, 4-15 parts of extreme pressure antiwear agents, 0.01-0.3 parts of defoaming agents, 1 part of ethylene diamine tetraacetic acid, and 2-6 parts of alkyl alanine surface active agents. According to the self-bacteriostasis general emulsion cutting fluid, an organic triethylhexanoin process is adopted, cutting fluids produced has strong cooling characteristics, lubricity and rust protection, and is easy to wash, defects of heavy loading water-soluble cutting fluids in rust protection and odor aspects in use are avoided, simultaneously, bacteriacides are replaced by the alkyl alanine surface active agents, therefore strong bacteriostatic capacity for bacteria, fungi and molds can be achieved without adding special bacteriacides into products, service life of products is prolonged, and cost of products is reduced.

Description

technical field [0001] The invention belongs to the field of cutting fluids, in particular to a self-inhibiting general-purpose emulsified cutting fluid and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of metal processing technology, the matching metal processing fluid has been constantly updated. Emulsified cutting fluid is a kind of water-based cutting fluid. At present, most products have the following problems: 1. The scope of application is narrow. A corrosion inhibitor can only have a slow-release effect on one metal. It is applied to cast iron, steel, aluminum, and magnesium. For unused metal materials such as copper and copper, products with different formulas need to be used respectively, so that one product can only be used for one or two kinds of metal materials, and the versatility is very low; 2. Since the emulsified cutting fluid contains a certain proportion of base oil, The oxidative corruption of oi...
