CN104479826A discloses a cutting fluid in the processing of superhard materials, which includes the following components: molybdenum disulfide, tartaric acid, chlorinated paraffin, oleic acid, sodium petroleum sulfonate, and transformer oil and / or soybean oil , the cutting fluid prepared by using the inventive method can still lubricate and cool under the high temperature condition of 600-1000°C, and is especially suitable for cutting high-hardness materials. The key technology that commonly used tools such as YW1 can process high-hardness materials. Compared with other cutting fluids, the advantage of this cutting fluid is that it can be better attached to the tip of ordinary tools, and it can cut high-hardness materials and generate high heat. Normal cutting of high-hardness materials under high-temperature conditions greatly improves tool life. When cutting high-hardness materials, ordinary turning tools can be used, which reduces production costs and meets the needs of actual production. The preparation of the cutting fluid is convenient and the preparation cost is not high. , but the service life of the cutting fluid of this invention is unknown
CN103351932A discloses a kind of transparent water-soluble cutting fluid, and this cutting fluid comprises: hydrophilic polyhydric alcohol, boric acid, sodium phosphate, aluminum alloy corrosion inhibitor, anionic surfactant, nonionic surfactant and water, pass mixer during preparation By mixing the substances, a uniformly dispersed cutting fluid can be obtained. This invention has good lubrication, anti-rust, cooling, cleaning and environmental protection performances, and overcomes the problem of large emission pollution of existing cutting fluids. Its performance is better than that of saponification Dissolved oils, vulcanized cutting oils and diesel oils, however the service life of the cutting fluid of this invention is unknown
[0004] In summary, in view of the problems that the existing cutting fluids are easy to be corrupted and smelly during use, and the service life is very short, it is necessary to develop an environmentally friendly cutting fluid with a long service life

Embodiment 1
[0031] This example provides four formulations of cutting fluids, ie, formulations A to D, as shown in Table 1 and Table 2 in detail.
[0032] Concrete component and content of table 1 formula A and B
[0033]
[0034] Concrete component and content of table 2 formula C and D
[0035]
Embodiment 2
[0037] This example provides the preparation method of cutting fluid, which is as follows: Weigh each component according to the proportion, add water, surfactant and extreme pressure agent to the rust preventive agent at 60-80 ° C in sequence, stir and dissolve, and then add in sequence Stir the corrosion inhibitor and defoamer until completely dissolved.
Embodiment 3
[0039] Using the preparation method provided in Example 2 and the four formulations in Example 1, four corresponding wire cutting fluids A to D were prepared, and their properties are shown in Table 3 and Table 4.
[0040] The cutting fluid performance of table 3 formula A and B
[0041]
[0042] Table 4 Cutting fluid properties of formulations C and D
[0043]
[0044] Comparing Table 3 and Table 4, it can be seen that the cutting fluids of formula A and formula B have good stability, no delamination, phase change and gelatinous state, and can be restored to the original state after the test without oil precipitation. In addition, the antirust and defoaming properties And good corrosion resistance. However, the cutting fluids of formula C and formula C were unstable in storage, and the corrosion test failed.

The invention provides an aqueous environment-friendly cutting fluid including raw materials of an anti-rust agent, a surfactant, an extreme pressure agent, a corrosion inhibitor, a defoamer, and water; the anti-rust agent is prepared from organic alcohol amine and borate; the surfactant is a mixture of a polyethylene glycol synthetic emulsifier and a composite polyol ester PE-25; the extreme pressure agent is a mixture of ZDDP and nano molybdenum oxide; the corrosion inhibitor is a mixture of benzotriazole and thiourea; the defoamer is at least one of B118, B103, B273 and B308. The inventionalso provides a preparation method of the aqueous environment-friendly cutting fluid. The raw materials in the formula are water-soluble and have good stability in water without separation of oil, andthe cutting fluid is free of toxic and harmful substances and is environment-friendly. With the cutting fluid for machining, a processed workpiece has high finish and is free of an extra cleaning step, so that process course is shortened and work efficiency is increased.
Description
technical field [0001] The invention belongs to the field of cutting fluids, and in particular relates to a water-based environment-friendly cutting fluid and a preparation method thereof. Background technique [0002] In the processing and manufacturing industry, metal cutting fluid mainly plays the role of cooling, lubrication, cleaning and rust prevention. In the current technology, whether the lubrication, cooling, cleaning and anti-rust ability of cutting fluid is excellent is closely related to the selection and use of additives. Selecting suitable additives can not only promote the performance of cutting fluid, but also can Ensure the quality and efficiency of cutting processing. [0003] CN103436343A discloses a water-based metal cutting fluid and a preparation method thereof. The main components include sorbic acid, sebacic acid, diethanolamine, triethanolamine, sodium molybdate, boric acid, lubricant, benzotriazole, monoethanolamine, Sodium nitrate and water, the...
