Description

Water-soluble metal multi-wire cutting fluid
Technical Field
The invention relates to the technical field of metal precision machining, in particular to a water-soluble metal multi-money cutting fluid.
Background
In the multi-wire cutting process of the metal copper sheet, the multi-wire cutting liquid is used as an auxiliary material product which must be used in the cutting process of the diamond wire cutting copper sheet, and the using amount of the multi-wire cutting liquid is increased along with the development of the multi-wire cutting industry in recent years. The production cost is greatly reduced, and the cutting fluid is developed from the prior oil-based cutting fluid to the water-based cutting fluid, and becomes the mainstream product at present.
However, since the development of the water-based cold cutting fluid is relatively fast, most of research on the water-based cold cutting fluid is based on industrial experience such as metal precision machining. Polyethers are the most popular market products. However, the method of addition is classified into two categories. The first is single component, which is diluted after directly adding water according to proportion; the other is two components, one of the two components is the main component of the cutting fluid, and the other is an antifoaming agent, a stabilizing agent and the like. From the aspect of cutting use, the single-component cutting fluid does not need to be further operated after being added, and is relatively suitable for large-scale cutting. However, since the single-component liquid is mostly an emulsion type liquid, the delamination, oil floating, and foaming are unstable. The two components are added respectively, so the operation is troublesome, but the layering and the foaming are relatively stable. When cutting copper sheets, the cutting fluid has the advantages of cleaning property, wettability and high dispersibility, and more importantly, a stable low-foam environment. Otherwise, fine powder is agglomerated, the wettability of a foaming part is reduced, and finally the problems of edge defect, line mark and the like are caused.
At present, the multi-wire cutting fluid is mainly used for cutting monocrystalline silicon and polycrystalline silicon, deep research is not carried out on the use of the multi-wire cutting fluid in the aspect of metal multi-wire cutting, the cutting fluid for the monocrystalline silicon and the polycrystalline silicon mostly uses the emulsified cutting fluid, the problems of layering, deterioration and the like easily occur in the using process of the emulsified cutting fluid, and the service life and the processing efficiency of the cutting fluid are reduced. Along with the development of the domestic multi-wire cutting industry, the multi-wire cutting fluid gradually develops towards the direction of total synthesis, and the total synthesis multi-wire cutting fluid is superior to the emulsifying multi-wire cutting fluid in the aspects of service life, cleaning performance and the like.
Therefore, the existing metal multi-wire cutting fluid mainly has the problems of low yield, low processing efficiency, serious loss of diamond wires, low cooling efficiency compared with the fully-synthesized multi-wire cutting fluid and the like, and the market situation is not wide.
Disclosure of Invention

Further, the solubilizer is alkyl carboxylic acid with 8-10 carbon atoms, and the weight percentage of the solubilizer is 5-15%.
Further, the weight percentage of the solubilizer is 6-8%.
Further, the pH regulator comprises one or more of ethanolamine and special alcohol amine.
