Micro-emulsified water-soluble cutting fluid and preparation method thereof

Abstract

The invention discloses micro-emulsified water-soluble cutting fluid and a preparation method thereof. The micro-emulsified water-soluble cutting fluid comprises the following components in percentage by weight: 6-15 percent of base oil or oiliness agent, 2-5 percent of nonionic surfactant, 5-10 percent of anionic surfactant, 5-8 percent of mixed alkylol amine, 10-15 percent of antirust agent, 0.08-0.1 percent of copper alloy corrosion inhibitor, 0-0.5 percent of ethylenediamine tetraacetic acid tetrasodium salt, 0.1-0.2 percent of antifoaming agent and the balance of water. The micro-emulsified water-soluble cutting fluid prepared by the invention is high in cooling property, antirust property and hard water resistance and hardly deteriorates or stinks, the product can inhibit fungi, bacteria and moulds very well without adding any special bactericide, the service life of the product is prolonged, and harm of the bactericide to skin irritation is avoided. The cutting fluid is reasonable in formula, multiple surfactants and aids are utilized, the provided cutting fluid is diluted with water according to a general ratio of 1:20 before being used, the antirust time of a single product exceeds 180 hours, the use of the product is not influenced even if the tank is not replaced within a year according to customer response, the manpower and material resources needed in the process of replacing the tank are saved, and the cost is saved.

Description

Technical field [0001] The invention relates to a microemulsified water-soluble cutting fluid. The invention also relates to a preparation method of a microemulsified water-soluble cutting fluid, belonging to the field of metal processing cutting fluids. Background technique [0002] Microemulsion cutting fluid is one of the water-based cutting fluids. Because of its low cost and excellent performance, it is widely used in the metal processing industry. It is especially suitable for all kinds of high-strength cutting processing, such as the processing of aluminum alloy and alloy steel. It is especially used for processing that requires high surface finish. It is also suitable for processing of ordinary steel and cast iron. The use concentration varies according to the processing technology and workpiece accuracy requirements, usually 6% to 10%. In particular, it is designed and developed for aluminum alloy processing. Its excellent lubricating performance can effectively reduce ...

Problems solved by technology

[0003] However, some micro-emulsified metalworking fluids currently contain a high proportion of base oil in the formula, and the oxidation and corruption of the oil will easily affect the service life of the entire product. Therefore, it is necessary to add a fungicide to prolong the service life. Moreover, the current Most of the fungicides on the market are irritating to the skin and harmful to the human body. In addition, most of the fungicides are sold at a relatively high price, which limits the cost of the product
