Problems solved by technology

[0003] Conventional mechanical processing, such as cutting, grinding, milling, sawing, etc., the pressure is not very high, the oil film is adsorbed on the metal surface with a certain strength, which plays a lubricating role, the metal surface does not directly contact, and will not be stuck during processing. When the pressure reaches a certain level, the oil film is squeezed out, and the metal surface can be in direct contact, thereby wearing the tool; while drilling, stretching, boring, tapping and other high-strength processing, due to excessive pressure, the strength of the oil film is limited If it is squeezed away, the metal surface will be in direct cont

Abstract

The invention discloses a long-life high-load metal working fluid and a preparation method thereof. At least one of polyol ester, II type hydrogenated oil, epoxidized soybean oil and epoxidized rapeseed oil is taken as base oil, an emulsification lubricant, an extreme pressure agent, a preservative, an anti-rusting agent, an oil-water balance agent, an aid and a defoaming agent are added, and the metal working fluid is prepared. The prepared metal working fluid has a good lubricating extreme pressure property, is long in anti-rusting period and service life, belongs to an environment-friendly metal working fluid and can meet the working environment under high-load conditions of drilling, tapping, reaming and the like of cast iron, carbon steel, stainless steel, aluminum alloys and other materials, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a metal working fluid for processes such as metal cutting, processing and forming, and belongs to the technical field of metal cutting and forming. Background technique [0002] As one of the country's pillar industries, the machinery and equipment manufacturing industry is developing rapidly, and the demand for metalworking fluids is increasing. In 2009, my country's manufacturing industry consumed about 300,000 to 500,000 tons of metal processing oil. However, the discharge of a large amount of metal processing waste liquid has caused increasingly serious ecological environmental pollution and endangered human health. There is an urgent need for greening of the manufacturing industry, especially the environmental protection of metal processing liquids. Metalworking fluids are mainly oil-based and water-based, and water-based metalworking fluids are divided into microemulsion type, emulsified type and fully synthetic type. W...
