Problems solved by technology
The quality of the wire drawing fluid directly affects the wire drawing effect. The wire drawing fluid with excellent performance can protect the mold very well and reduce the phenomenon of wire breakage and mold wear. On the contrary, it will seriously affect the wire drawing quality. With the application of the wire drawing process, the market The quality requirements for wire drawing liquid are getting higher and higher. The existing copper wire drawing liquid mainly uses emulsion or microemulsion products containing mineral oil system, which has problems such as poor emulsion stability, corrosion of metal wires, high energy consumption, and difficulty in cleaning. , which restricts the quality of wire drawing and drawing, it is urgent to improve its formula and process to make it more efficient, environmentally friendly, free of mineral oil, and easy to clean later

The invention relates to a conversion method of waste oil and application of the waste oil in copper wire drawing liquid. The method comprises the following steps: in the presence of a catalyst composition, the waste oil and polyethylene glycol or a derivative of the polyethylene glycol are subjected to a reaction; the catalyst composition is prepared from alkali and a 2-azaindolizine derivative; the converted product can be used for the copper wire drawing liquid. The application range of the waste oil is widened, meanwhile, a green active component of the copper wire drawing liquid is provided, and the method is suitable for industrial application.
Description
technical field [0001] The invention belongs to the technical field of waste oil utilization, and in particular relates to a conversion method of waste oil and its application in copper wire drawing liquid. Background technique [0002] Waste oil mainly comes from catering waste oil, which contains a large number of bacteria and toxic substances. Among them, aflatoxin is 100 times more toxic than Bishuang. Long-term consumption is extremely harmful to the human body, but it is difficult to process under the current refining technology For this purpose, turning waste oil into a useful industrial resource can open the "bottleneck" of its recycling, thereby cutting off the way to the dining table. [0003] At present, the main industrial application of waste oil is to convert it into biodiesel, among which the most research is to convert it into fatty acid methyl ester (first generation biodiesel) by transesterification method, but because its structure is different from that o...
