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.
