On July 8, 2015, Wang, Guidong; Song, Rui published a patent.SDS of cas: 23256-42-0 The title of the patent was A kind of composite saponification cutting fluid. And the patent contained the following:
The invention discloses a kind of composite saponification cutting fluid, which is made up of the following raw materials by weight parts: oleic acid 2-3, trimethoprim lactate 0.1-0.2, Na myristate 3-5, p-nitrophenol 0.2-0.4, castor oil polyoxyethylene ether 0.1-0.2, KOH 0.3-0.5, glyceryl carboxylate 0.2-0.3, polyethylene glycol diglycidyl ether 5-7, raw silk 10-13, polymaleic anhydride 10-16, Span 80 0.8-2, and deionized H2O 170-200. The preparation method includes the following steps: (1) adding raw silk to 0.4-0.6% Na carbonate solution, soaking at 98-100° for 60-80 min, filtrating, drying, mixing with trimethoprim lactate, grinding, adding Span-80, deionized H2O, stirring, adding polyethylene glycol diglycidyl ether, mixing and ultrasonic treating for 30-35 min, obtaining fibroin emulsion; (2) taking KOH, adding deionized H2O, stirring, adding oleic acid, heating to 70-80°C, adding Na myristate and p-nitrophenol, insulating and reacting for 30-40 min, obtaining composite saponification liquid; (3) mixing the fibroin emulsion with polymaleic anhydride, standing at 65-70°C for 30-40 min, adding composite saponification liquid, stirring for 10-16 min, obtaining antirust blended emulsion; (4) mixing the antirust blended emulsion with the residual raw materials, stirring for 20-30 min, obtaining cutting fluid. The composite saponification liquor added in cutting fluid of the present invention has excellent extreme pressure and antiwear behavior, can provide long lasting abrasion and corrosion protection. The experimental process involved the reaction of 5-(3,4,5-Trimethoxybenzyl)pyrimidine-2,4-diamine 2-hydroxypropanoate(cas: 23256-42-0).SDS of cas: 23256-42-0
