[0048] 2) sequentially adding monoethanolamine, isopropanolamine, 1,2,3-benzotriazole and stirring for 15-30min to form a composite rust inhibitor;

[0049] 3) Add pure water to flush the raw materials on the reactor wall into the system, and stir for 20-40min;

[0050] 4) Cool down to 30-40℃, add compound lubricant and auxiliary rust inhibitor and stir for 20-40min;

[0051] 3) Add nonionic surfactant, monohydric alcohol and base oil, and stir for 20-40min;

[0052] 4) Add remaining water, anionic surfactant, bactericide and defoaming agent, and stir until the solution is clear and transparent to obtain metal cutting fluid.

Embodiment 1

[0056] A preparation method of a green and environment-friendly metal cutting fluid, comprising the following steps:

[0057] 1) the reactor is heated to 70 ℃, then the mixture of (5%) boric acid and triethanolamine is added successively (boric acid and triethanolamine mass ratio are 1:2), and stirring reaction 30min obtains boric acid triethanolamine ester;

[0058] 2) successively add (5%) isopropanolamine, (7%) monoethanolamine, (4%) lauric acid, (0.2%) 1,2,3-benzotriazole and stir for 15min to form a composite Rust inhibitor;

Abstract

The invention relates to a green and environment-friendly metal cutting fluid as well as a preparation method and application thereof. The metal cutting fluid comprises the following components: 12-30% of base oil, 12-30% of a nonionic surfactant, 2-3% of an anionic surfactant, 10-25% of a composite anti-rust agent, 15-20% of a composite lubricant, 5-7% of monohydric alcohol, 0.1-0.2% of a defoaming agent, 0.8-2.5% of a bactericide and the balance of water. The preparation method comprises the following steps of: heating and mixing the composite anti-rust agent and part of water, cooling, adding the composite lubricant and an auxiliary anti-rust agent, mixing well, respectively adding the nonionic surfactant, the monohydric alcohol and the base oil, finally adding the other components, and stirring until the solution is clear, thereby obtaining the metal cutting fluid. Compared with the prior art, biodiesel prepared from illegal cooking oil is adopted as the base oil, reutilization of the illegal cooking oil is realized, and the problem that the illegal cooking oil flows into the food market is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of metal cutting and relates to a green and environment-friendly metal cutting fluid and a preparation method thereof, in particular to a green and environment-friendly cutting fluid using biodiesel as a base oil and a preparation method thereof. Background technique [0002] The problem of environmental resources is an important problem facing human beings today. In the process of metal processing, metal cutting is a widely used processing method. During the cutting process, a large amount of friction and heat will be generated between the tool and the workpiece, which not only affects the processing efficiency and the quality of the workpiece, but also affects the tool and the workpiece. damage to the device. Therefore, cutting fluids with good lubrication, cooling, cleaning and anti-rust properties are the goals that have been pursued in metal cutting. [0003] Traditional metal cutting fluids, such as ...
