Embodiment 1

[0018] A kind of raw silk bentonite cutting fluid, it is made up of the raw material of following weight part:

[0019] Sodium dihydrogen phosphate 1, zinc pyrithione 0.5, N-ethyl-o-p-toluenesulfonamide 0.8, nano-bentonite 4, polylactic acid 3, dimethyl sulfoxide 20, raw silk 4-5, aminotriethyl borate 30 , Span 803, deionized water 300.

[0020] A preparation method of raw silk bentonite cutting fluid, comprising the following steps:

[0021] (1) adding polylactic acid to dimethyl sulfoxide to obtain a polylactic acid solution;

[0022] (2) Add the above-mentioned raw silk to 0.6wt% sodium carbonate solution that is 90 times its weight, soak it at 100°C for 80 minutes, filter, dry, and grind it into fine powder. Mix, add 90% of the weight of the above-mentioned deionized water, stir evenly to obtain silk fibroin lubricating liquid;

[0023] (3) Add sodium dihydrogen phosphate to the remaining deionized water, stir evenly, add nano-bentonite and the remaining Span 80, keep s...

Abstract

The invention discloses a raw silk bentonite cutting fluid which comprises the following raw materials by weight: 1 to 2 parts of sodium biphosphate, 0.5 to 2 parts of zinc pyrithione, 0.8 to 1 part of N-ethyl-o/p-toluene sulfonamide, 3 to 4 parts of nano bentonite, 3 to 4 parts of polylactic acid, 16 to 20 parts of dimethyl sulfoxide, 4 to 5 parts of raw silk, 20 to 30 parts of triethanolamine borate, 2 to 3 parts of span 80, and 200 to 300 parts of deionized water. A fibroin lubricating liquid (an intermediate product of the raw silk bentonite cutting fluid) takes natural silk as a main material, thereby being nontoxic, free of pollution, and high in lubricity; triethanolamine borate, which is excellent in extreme pressure lubricity, rust-proof, anti-bacterial, capable of sterilizing and the like, is mixed with the fibroin lubricating liquid to obtain a liquid mixture; the liquid mixture is modified with polylactic acid. Therefore, the fracture strength and wettability of a blend membrane can be improved; a lubricating film layer formed on the friction metal surface can be more stable; the extreme pressure anti-wear property and reaction activity are improved effectively.

Description

technical field [0001] The invention mainly relates to the field of cutting fluid, in particular to a raw silk bentonite 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 country'...
