Environment-friendly high-water-based cutting fluid for metal machining

Abstract

The invention discloses environment-friendly high-water-based cutting fluid for metal machining. The environment-friendly high-water-based cutting fluid is prepared from the following components in parts by weight: 5 to 20 parts of refined biological oil, 1000 parts of de-ionized water, 0.1 to 3 parts of colloidal graphite powder, 0.1 to 2 parts of nano titanium dioxide, 10 to 50 parts of sodium sulfite, 5 to 20 parts of dioctyl sodium sulfosuccinate and 0.6 to 8 parts of n-undecyl alcohol. The high-water-based cutting fluid disclosed by the invention has good lubricating, washing, cooling and dust-proof effects on workpieces in a metal machining process; the machining precision of the workpieces can be remarkably improved, the abrasion of cutters is reduced and the product is environmentally friendly and biodegradable.

Description

technical field [0001] The invention relates to the field of cutting fluids, in particular to an environment-friendly high water-based cutting fluid composition for metal processing. Background technique [0002] Machining, especially metal processing, often requires lubrication for turning, milling, planing and grinding. In addition, it is necessary to clean the debris during the processing, cool the high temperature generated during the processing, and prevent the metal from rusting during the processing. Therefore, Usually requires the participation of cutting fluid. According to the dispersed phase, cutting fluid mainly includes water-based cutting fluid and oil-based cutting fluid. In recent years, water-based cutting fluids have been widely welcomed due to their good cleaning and cooling effects. However, the lubricating and antirust properties of the existing water-based cutting fluids need to be improved, and there are problems such as easy odor after storage. For ...

Problems solved by technology

However, the lubricating and anti-rust properties of the existing water-based cutting fluids need to be improved, and there are problems such as easy odor after storage. For this reason, various auxiliary additives are often added to them, resulting in increased costs and affected the stability of the cutting fluid.

In addition, many cutting fluids also contain nitrite and other substances that are banned by the state. The use of these cutting fluids has caused a great threat to the environment and people in contact. Although there are some reports of environmentally friendly cutting fluids, but Often the composition is more complex, resulting in higher cost and limited application
