With the rapid development of the economy, the processing of various steel and aluminum alloys is also developing rapidly. At present, there are few researches on metal cutting fluids in the lubrication of steel and aluminum alloys in my country, mainly imported. The research work in this area in our country It started late, and mainly focused on material processing and molding, and did not pay enough attention to the problems of lubrication and anti-corrosion in cutting processing

Abstract
The invention discloses pectin-modified micro-emulsion cutting fluid. The pectin-modified micro-emulsion cutting fluid is prepared from the following raw materials: refined mineral oil, TEA-lauryl sulfate, polyoxyethylene lauryl ether, cocamidopropyl betaine, fatty alcohol-polyoxyethylene ether, triethanolamine, antifoaming agent, amide borate, palmitic acid, sodium chloride, glycerol, tetraethoxysilane, oleic acid, acrylamide, azodiisobutyronitrile 3-4, aluminum borate whisker, pectin, dihydroxyl pentasulfide, a proper amount of ethyl acetate, a proper amount of ammonia water, a proper amount of absolute ethyl alcohol and a proper amount of deionized water. The prepared micro-emulsion cutting fluid has very high anti-friction extreme pressure performance, can be used for preventing adhesive wear of tools, increasing surface machining accuracy and prolonging the service lives of the tools, can meet the cooling performance in a machining process, and has a good cleaning effect; through a unique formula design, the pectin-modified micro-emulsion cutting fluid has very high biological stability and a long life cycle, and is free from irritation and pollution.
Description
technical field [0001] The invention relates to the technical field of microemulsion cutting fluid, in particular to a pectin-modified microemulsion cutting fluid. Background technique [0002] Metal cutting fluid is an important supporting material in the process of metal processing, and its main functions are cooling, lubrication, cleaning and rust prevention. According to the condition of the medium, it is divided into two categories: oil-based cutting fluid and water-based cutting fluid. The main component of oil-based cutting fluid is usually mineral oil (also vegetable oil or other synthetic materials), and oil-soluble antirust agent and oily agent are added. It is blended with extreme pressure lubricants containing active elements. Compared with water-based cutting fluids, oil-based cutting fluids have better lubricating performance and anti-rust performance, but they have disadvantages such as easy to generate oil mist and fire. Water-based cutting fluids Cutting fl...
