Metal cutting fluid with good rust prevention and mildewproof effects and preparation method of metal cutting fluid

Abstract

The invention discloses a metal cutting fluid with good rust prevention and mildewproof effects. The metal cutting fluid is characterized by being prepared from raw materials in parts by weight as follows: 6-8 parts of inositol hexaphosphate, 1-2 parts of 2-mercaptobenzothiazole, 1-2 parts of ditetradecyl thiodipropionate, 2-3 parts of EDTA (ethylene diamine tetraacetic acid) disodium salt, 5-7 parts of glycerin, 2-3 parts of monoethaneamine benzoate, 1-2 parts of a silane coupling agent KH-550, 1-2 parts of sodium carbonate, 4-6 parts of coconut oil, 2-3 parts of sodium alkyl benzene sulfonate, 1-2 parts of sodium hydroxide, 3-5 parts of polyether polyol, 5-7 parts of an auxiliary and 150-180 parts of water. The auxiliary added to the cutting fluid enhances the dispersion, lubrication and film-forming property of the cutting fluid; the added inositol hexaphosphate has excellent rust prevention capability, forms a compact monomolecular film on the surface of metal, effectively resists metal corrosion and rusting, has long maintaining time and remarkable effect and is non-toxic and environment-friendly; the added 2-mercaptobenzothiazole has good sterilization and corrosion resistance capability, invasion of microorganisms, bacteria and the like is resisted, deterioration is prevented, and the storage time is long; and the prepared cutting fluid has a wide application prospect.

Description

technical field [0001] The invention relates to the field of cutting fluids, in particular to a metal cutting fluid with excellent anti-rust and anti-mildew effects and a preparation method thereof. Background technique [0002] Cutting fluid is an industrial liquid used in metal cutting, chipping and grinding to cool and lubricate cutting tools and workpieces. Cutting fluid is made of a variety of super functional additives through scientific compounding. Since synthetic metalworking fluid does not contain mineral oil, polyether is usually used to increase the lubricating performance of the working fluid. In view of its limited lubricating extreme pressure performance, it is mainly used in some materials and processes that do not require high lubricating extreme pressure. It does not meet the requirements for harsh and difficult-to-machine materials and processes such as stainless steel and high-hard alloy steel. Since emulsified cutting fluids all contain mineral oil or / a...

AI Technical Summary

Problems solved by technology

Since the emulsified cutting fluid contains mineral oil or / and vegetable oil, it has defects such as easy deterioration and odor, short storage and use time, frequent discharge, large displacement, polluting the environment, and consuming a lot of energy.
