Abstract

The invention discloses a noncorrosive water-based cutting fluid. The cutting fluid comprises the following components in parts by weight: 7-18 parts of lubricating agent, 18-44 parts of antirust agent, 5-15 parts of cleaning agent, 5-15 parts of protective agent, 0.6-2 parts of alkali, 0.5-2 parts of softening agent, 0.1-1 parts of nonionic surfactant, 1 part of disinfectant, 1-2.5 parts of preservative, 1-5 parts of copper corrosion inhibitor, 0.1-1 part of filming agent, and the balance of water. The cutting fluid disclosed by the invention can be applied to machine tool processing, and has the functions of rust resistance, lubrication, cleaning and temperature reduction.

Description

technical field [0001] The invention relates to a cutting fluid, in particular to a non-corrosive water-based cutting fluid. Background technique [0002] When the existing metal cutting fluid is used, the concentrated solution needs to be prepared into a high water-based dilution solution with water. Due to its formula and other reasons, it is not resistant to hard water, and the use of hard water will cause the quality of cutting fluid to decline, increase the processing cost, and bring trouble to use. At the same time, there are also unsatisfactory aspects such as lubricity, rust prevention, cooling, and defoaming performance. [0003] In the current metalworking fluid industry, for harsh and difficult-to-machine materials and processes (materials such as stainless steel, high-hard alloy steel, etc.; processes such as tapping, deep hole drilling, reaming, etc.), high lubrication and extreme pressure performance must be used Metalworking fluids and sometimes even cutting...
