Abstract

The invention discloses water-soluble cutting fluid. The cutting fluid consists of the following components in percentage by weight: 15 to 25 percent of oleate-2-ethylhexyl ester, 2 to 8 percent of 3,5,5-trimethyl caproic acid, 3 to 10 percent of sebacic acid, 5 to 10 percent of mono ethanolamine, 15 to 20 percent of triethanolamine, 5 to 10 percent of diglycol, 3 to 10 percent of monoisopropanolamine, 15 to 20 percent of polyethylene glycol 600 and 20 to 30 percent of water. The invention also discloses a preparation method of the water-soluble cutting fluid. The method comprises the following steps of: reacting by mixing the oleate-2-ethylhexyl ester, the mono ethanolamine, the 3,5,5-trimethyl caproic acid and a part of water to obtain alkylol amine synthesis ester mixture A; reacting by mixing the sebacic acid, the triethanolamine, the monoisopropanolamine and the rest amount of water to obtain alkylol amine synthesis ester mixture B; and reacting by mixing the diglycol, the polyethylene glycol 600, the alkylol amine synthesis ester mixture A and the alkylol amine synthesis ester mixture B to obtain a finished product.

Description

technical field [0001] The invention belongs to the field of metal working fluids, and in particular relates to a water-soluble cutting fluid and a preparation method thereof. Background technique [0002] Metal cutting is a widely used processing method. During the cutting process, a lot of friction and heat will be generated between the tool and the workpiece, which not only affects the processing efficiency and the quality of the workpiece, but also causes damage to the tool and equipment. Therefore, cutting fluids with good lubricating, cooling, cleaning and anti-rust properties are the goals that have been pursued in metal cutting. Since the performance of cutting fluid depends on its composition, and there are many kinds of cutting fluids with various compositions, cutting fluids are usually divided into two categories: oil-based and water-based, each of which has its own advantages and disadvantages and meets different processing needs. , and products with green and ...
