Environment-friendly cutting fluid and preparation method thereof

Abstract

The invention provides an environment-friendly cutting fluid and a preparation method thereof. The cutting fluid includes the components in parts by weight: 6-10 parts of sodium molybdate, 8-12 parts of solid paraffin, 50-60 parts of white mineral oil, 5-10 parts of erucyl amide, 4-8 parts of polyurea, 3-6 parts of phosphatidyl ethanolamine, 3-6 parts of phosphatidyl choline, 5-10 parts of glycerol monostearate, 8-12 parts of glycerol, 4-8 parts of zinc stearate, 2-4 parts of boric acid, 1-2 parts of naphthenic base oil, 1-3 parts of sodium bicarbonate, 1-3 parts of glycerol trioleate, 0.5-1 part of sodium silicate, and 15-25 parts of water. The preparation method comprises the steps: firstly, mixing and heating the components except phosphatidyl ethanolamine, glycerol monostearate and the naphthenic base oil, then adding the remaining three components, continuing to heat, carrying out heat preservation, and cooling to obtain the product. The raw materials used in the cutting fluid and the generated product all can be rapidly degraded and are all harmless to both human bodies and environment, and moreover, all the lubrication, rust protection, cooling and cleaning functions are not inferior to those of other high-quality cutting fluids; and the preparation method is simple in steps, easy to control, prone to industrialization production, and low in production cost.

Description

technical field [0001] The invention relates to the field of metal cutting agents, in particular to an environment-friendly cutting fluid and a preparation method thereof. Background technique [0002] Metal cutting is the most common and widely used type of metal processing, such as in the machining industry. While it creates huge benefits for human beings, it also poses a hazard to human health and causes serious pollution to the environment. First of all, if the waste liquid used in cutting processing is directly discharged or incinerated without effective treatment, it will pollute water resources, the atmosphere and soil. For example, the accumulation of rust inhibitor sodium phosphate in cutting fluid will cause rivers and lakes And appear Chihu; anticorrosion fungicide phenol biodegradability is poor, toxic to fish and other aquatic organisms. With the increasing awareness of global human environmental protection and the increasing attention of the international com...
