Embodiment 1

[0026] Embodiment 1 biodiesel is used to produce L-MHC type cutting fluid

[0027] Pump 30 parts by weight of mineral oil into the blending kettle, stir, and self-circulate, then pump 50 parts by weight of biodiesel into the blending kettle, stir evenly, heat up to 60°C, and add in order: ① Oxidized rapeseed oil: 5 parts by weight ② T202: 2 Parts by weight ③ T-301: 8 parts by weight ④ T-405: 1 parts by weight ⑤ T-746: 0.01 parts by weight ⑥ T-706: 1.2 parts by weight ⑦ T-901: 0.01 parts by weight ⑧ Nano-boron nitride: 0.4 parts by weight, after blending 60 Minutes later, the sampling analysis is qualified, and the filling is measured.

[0028] The product quality index prepared by embodiment 1 is as follows:

[0029] project

[0030] The product L-MHC type cutting fluid prepared in Example 1 is applied by the user in stainless steel cutting conditions, and its performance fully meets the product quality index of the workpiece.

Abstract

The invention discloses a method using biodiesel to prepare environmentally-friendly metal working liquids. The method is a new use of the biodiesel. The metal working liquids prepared by using the biodiesel as a raw material pass test of physical and chemical indexes, and practical conditions of equipment workpieces, and the performances of the metal working liquids prepared in the invention reach and exceed the performances of metal working liquids produced by using mineral oil as base oil.

Description

technical field [0001] The invention belongs to the production field of metal working fluids, in particular, the invention relates to the application of biodiesel for preparing environment-friendly metal working fluids. Background technique [0002] Metalworking fluids are mainly liquids for metalworking, mainly for lubrication and cooling, and also for rust prevention and cleaning. With the rapid development of the domestic manufacturing industry, the demand for metalworking fluids for mechanical equipment is gradually increasing. In the prior art, the production of metalworking fluids requires a large amount of mineral base oil. And in order to make up for the defects in the application of mineral base oil, it is also necessary to add a large amount of additives containing sulfur, nitrogen, chlorine and heavy metals to meet the technological requirements of metal processing, which will inevitably cause environmental pollution.
