Abstract
The invention relates to the technical field of metal cutting fluid, in particular to low-foam environment-friendly fully-synthetic water-based cutting fluid and a preparation method thereof. The low-foam environment-friendly fully-synthetic water-based cutting fluid comprises the following components in percentage by mass: 5-15% of lubricant, 5-10% of solubilizer, 15-25% of pH regulator, 0.1-1.2% of antirust agent, 1-5% of extreme pressure antiwear agent, 0.2-1% of vegetable oil modified defoaming agent, 0.05-1% of EDTA disodium, 0.02-2% of bactericide and the balance of deionized water; the lubricant is a compound of trans-block polyether polyol 1740 and 1720 mixed according to a weight ratio of 1:2-2: 1. The water-based cutting fluid disclosed by the invention is low in foam, long in service life and small in environmental pollution.
Description
Technical Field
The invention relates to the technical field of metal cutting fluid, in particular to low-foam environment-friendly fully-synthetic water-based cutting fluid and a preparation method thereof.
Background
With the development of modern machining in the directions of high speed, strength and precision, the development of hard-to-machine materials such as super-hard materials, super-strength materials and the like also increases the difficulty of cutting machining. The reasons for the two aspects are that the friction force and the friction heat in the cutting process are greatly improved, and the metal cutting fluid is required to have better lubricating, cooling, cleaning and rust preventing properties so as to obtain an ideal processing surface.
The metal cutting fluid can be divided into two categories of water-based cutting fluid and oil-based cutting fluid, the reasonable selection of the cutting fluid is considered according to comprehensive conditions such as workpiece materials, cutter materials, processing methods, technical requirements, machine tool categories and the like, wherein the water-based cutting fluid is commonly used in metal processing, and the water-based cutting fluid can be divided into emulsion, semisynthetic cutting fluid and fully synthetic cutting fluid.
In general, a water-soluble polyether, which is a lubricant component, is required to be added to semi-synthetic cutting fluids and fully synthetic cutting fluids, and has better cooling property, stability, antibacterial property, hard water resistance and defoaming property than common water-soluble oily agents such as fatty acid soaps. However, the polyether contains hydrophilic and lipophilic groups, the surface tension is low, foam is inevitably generated in the using process, and the metal processing process is greatly influenced by the generation of the foam. Meanwhile, when the water-based cutting fluid is used, the metal cutting fluid fails due to microbial breeding, and the cutting fluid is easy to grow and propagate a large amount of microbes such as bacteria due to improper storage, so that oil substances in the cutting fluid are biochemically decomposed and deteriorated and smelly, and therefore, a bactericide is often added into the cutting fluid to prolong the service life of the cutting fluid, but the bactericide damages the environment due to improper use, and causes pollution.
