Embodiment 1

[0017] A kind of composite saponified cutting fluid, it is made up of the raw material of following weight part:

[0018] Oleic acid 2, trimethoprim lactate 0.2, sodium myristate soap 3, p-nitrophenol 0.4, castor oil polyoxyethylene ether 0.2, potassium hydroxide 0.5, glyceryl carboxylate 0.3, polyethylene glycol diglycidyl Ether 7, raw silk 13, polymaleic anhydride 16, Span 800.8, deionized water 200.

[0019] A preparation method of compound saponified cutting fluid, comprising the following steps:

[0020] (1) Add the above-mentioned raw silk to 0.6wt% sodium carbonate solution 100 times its weight, soak it at 100°C for 80 minutes, filter, dry, mix with trimethoprim lactate, grind into fine powder, add Span 80, 70% by weight of the above-mentioned deionized water, stir evenly, add polyethylene glycol diglycidyl ether, mix and ultrasonicate for 35 minutes, and obtain silk fibroin emulsion;

[0021] (2) Take potassium hydroxide, add 30% of the weight of the remaining deioni...

Abstract

The invention discloses a composite saponification cutting liquid which consists of the following raw materials in parts by weight: 2-3 parts of oleic acid, 0.1-0.2 part of trimethoprim lactate, 3-5 parts of sodium myrastate, 0.2-0.4 part of p-nitrophenol, 0.1-0.2 part of polyoxyethylene castor oil, 0.3-0.5 part of potassium hydroxide, 0.2-0.3 part of carboxylic acid glyceride, 5-7 parts of polyethylene glycol diglycidyl ether, 10-13 parts of raw silk, 10-16 parts of polymaleic anhydride, 0.8-2 parts of span-80 and 170-200 parts of deionized water. The fibroin emulsion takes silk as a main material, is non-toxic and free of pollution and high in lubrication property, polyoxyethylene castor oil can be adopted for modification, the flexibility, the hydrophilia and the stability of the emulsion in membrane preparation can be improved, and polymaleic anhydride which is finally added can be adhered to the surface of the membrane, so that the membrane can be immobilized, air can be isolated, and a further anti-rusting function can be achieved. The composite saponification cutting liquid with the cutting liquid is excellent in extreme-pressure wearing resistance, and long-lasting anti-wearing and rusting protection can be achieved.

Description

technical field [0001] The invention mainly relates to the field of cutting fluids, in particular to a compound saponified cutting fluid. Background technique [0002] Cutting fluid is an industrial liquid used in metal cutting and grinding to cool and lubricate cutting tools and workpieces. Cooling performance, lubricating performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, easy to dilute. It overcomes the shortcomings of traditional soap-based emulsions, which are easy to smell in summer, hard to dilute in winter, and poor anti-rust effect, and has no adverse effect on lathe paint. It is suitable for cutting and grinding of ferrous metals and is currently the most advanced grinding product. [0003] In order to reduce the loss caused by wear and tear in the process of metal processing, various production enterprises have higher and higher requirements for the performance of metal cutting fluid; at the same time, due to the countr...
