Embodiment 1
[0016] A kind of raw silk vulcanization cutting fluid, it is made up of the raw material of following weight part:
[0017] Alkenyl succinate 3, sodium thiosulfate 3, disodium hydrogen phosphate 1, linoleic acid 2, casein 0.6, T405 sulfurized olefin cottonseed oil 0.7, polylactic acid 3-4, dimethyl sulfoxide 20, raw silk 5. Aminotriethyl borate 30, Span 801, deionized water 200-300.
[0018] A method for preparing raw silk vulcanized cutting fluid, comprising the following steps:
[0019] (1) Take the above-mentioned dimethyl sulfoxide, add polylactic acid, and stir evenly to obtain a polylactic acid solution;
[0020] (2) Add the above-mentioned raw silk to 0.6wt% sodium carbonate solution that is 100 times its weight, soak it at 100°C for 80 minutes, filter, dry, mix with casein, grind into fine powder, and mix with the above-mentioned Span Mix 70% of 80% by weight, add 70% by weight of the above-mentioned deionized water, and stir evenly to obtain silk fibroin lubricating...

The invention discloses a raw silk sulfurized cutting fluid which comprises the following raw materials by weight: 3 to 4 parts of alkenyl succinate, 3 to 5 parts of sodium thiosulfate, 1 to 2 parts of sodium hydrogen phosphate, 1 to 2 parts of linoleic acid, 0.6 to 2 parts of casein, 0.7 to 2 parts of sulfurized olefin cotton oil T405, 3 to 4 parts of polylactic acid, 13 to 20 parts of dimethyl sulfoxide, 4 to 5 parts of raw silk, 20 to 30 parts of triethanolamine borate, 1 to 2 parts of span 80, and 200 to 300 parts of deionized water. A fibroin lubricating liquid (an intermediate product of the raw silk sulfurized cutting fluid) takes natural silk as a main material, thereby being nontoxic, free of pollution, and high in lubricity; sulfurized olefin cotton oil and triisopropyl borate, which are both excellent in extreme pressure lubricity and anti-abrasion property, are 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, reaction activity and rust prevention property are improved effectively.
Description
technical field [0001] The invention mainly relates to the field of cutting fluids, in particular to a raw silk vulcanized 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...
