Preparation method of cutting fluid for hardware alloy cutter or processed workpiece as hardware alloy

Abstract

The invention discloses a preparation method of a cutting fluid fora hardware alloy cutter or a processed workpiece as a hardware alloy. The preparation method of the cutting fluid comprises the following steps of: adding 5-7 percent of boracic acid and 24-26 percent of 2-amino-2-methyl-1-propanolamine into water; stirring the mixture under the condition of 40-50DEG C to be completely dissolved; cooling the dissolved solution to 25-35DEG C; then adding 3-5 percent of polyoxyethylene octadecyl phosphate, 5-7 percent of polyoxyethylene phenyl phosphate, 2-4 percent of dibutyl phthalate, 6-8 percent of phenol ether phosphate, 2-4 percent of sodium benzoate, 2-4 percent of propanetriol, 0.4-0.6 percent of isothiazolin one, 0.6-0.8 percent of benzotriazol and 0.3-0.5 percent of nonylphenol polyoxyethylene ether one by one and fully stirring; after the substances are completely dissolved, adding 0.6-1.0 percent of methyl silicone oil and then stirring for 60-90 minutes; and finally, adjusting the pH value to 8.5-9.5, wherein various components are counted according to weight percentage and the balance of water is counted according to weight percentage.

Description

technical field [0001] The invention relates to the technical field of metal cutting, in particular to a method for preparing a cutting fluid using a cemented carbide tool or a processed workpiece as a cemented carbide. Background technique [0002] Water-based metal cutting fluid can be divided into three types: soluble oil (emulsion), semi-synthetic cutting fluid (microemulsion) and fully synthetic cutting fluid. Compared with soluble oil and semi-synthetic cutting fluid, fully synthetic cutting fluid does not contain mineral oil, and its various components such as anti-rust agent, extreme pressure anti-wear additive, surfactant, preservative and defoamer and other additives are Soluble in water, the diluent is transparent or translucent. The fully synthetic cutting fluid has good cooling effect, clean processing place and stable product performance. It is a kind of metalworking fluid with a wide range of applications. [0003] However, fully synthetic cutting fluids usu...

Problems solved by technology

Metal cobalt is the binder of cemented carbide such as tungsten carbide cobalt. If the cobalt element in tungsten carbide cobalt cemented carbide is leached when using cemented carbide tools or grinding cemented carbide, on the one hand, it will directly It affects the toughness and shock resistance of cemented carbide, and on the other hand, it causes colored stripes to appear on the surface of tungsten carbide cobalt cemented carbide products, which directly affects the appearance of the product

[0004] In the case of using cemented carbide tools or grinding cemented carbide, in order to avoid the leaching of cobalt in cemented carbide such as tungsten-cobalt or titanium-cobalt by fully synthetic cutting fluid, domestic scholars replace triethanolamine oleate with triethanolamine Ethanolamine, which can partially reduce the leaching of cobalt in the alloy by fully synthetic cutting fluids, but still cannot completely inhibit the leaching of cobalt (see: Zhang Haoqiang. Study on the mechanism and countermeasures of cobalt leaching in cemented carbide tools, master degree of Hebei University of Technology Paper, 2005)

[0005] Therefore, the cutting fluid in the prior art is not suitable for processing with cemented carbide tools, or is not suitable for cutting cemented carbide
