Problems solved by technology

[0003] Although fully synthetic products use chemical raw materials as the main product, the low-end grinding fluid even uses banned nitrite and organic phenol as the main components. These additives have certain carcinogenic effects and will endanger the health of operators during use. , pollute the water body after discharge, causing water resource pollution and environmental damage
And there are poor cleaning performance and inaccurate processing accuracy. Most of them are only used for rough grinding and are not suitable for fine grinding. question

Abstract

The invention relates to the field of metal cutting additives, in particular to a grinding fluid for metal processing and a preparation method thereof. According to a technical scheme adopted by the invention, the grinding fluid for metal processing is composed of the following components by weight percentage: 5-15% of a PH value stabilizer, 3-5% of a surfactant, 5-10% of a water-borne lubricant,5-15% of an antirust agent, 4-8% of a coupling agent, 0.2-1% of a bactericide, 0.1-1% of a defoamer, 1-3% of a corrosion inhibitor, 0.2-0.4% of a settling agent, and the balance deionized water. The invention has the advantages that: the grinding fluid for metal processing adopts triethanolamine oleate as the surfactant, has good permeability and wettability, is conducive to entering a high temperature and high pressure working face, and at the same time is also a lubricant, the molecule has strong polar groups, can achieve strong adsorption with the metal surface, and chemical reaction can becarried out to form a firm physical absorption film and chemical reaction film with certain carrying capacity.

Description

technical field [0001] The invention relates to the field of metal cutting additives, in particular to a grinding fluid for metal processing and a preparation method thereof. Background technique [0002] Grinding is a commonly used semi-finishing and finishing method. Grinding wheel is a cutting tool for grinding. Grinding is performed by a large number of randomly distributed abrasive grains on the surface of the grinding wheel on the surface of the workpiece to perform three functions: friction, scoring and cutting. Based on the comprehensive results, the grinding fluid is required to have excellent lubrication, cooling, cleaning, anti-rust and defoaming properties, so as to prolong the durability of the grinding wheel, improve the machining accuracy and surface roughness of the workpiece, improve the processing efficiency and product quality and reduce energy consumption. consumption. Compared with oil-based grinding fluids and oil-containing water-based grinding fluids...
