Embodiment 3
[0054] Isopropanolamine 6%, nano-silicon anticorrosion agent 3%, triazine polycarboxylate 6%, methylbenzotriazole 3%, self-emulsifying ester 6%, tall oil 6%, dioctyl terephthalate Ester 40%, Guerbet alcohol 4%, ether carboxylic acid formulation 4%, cardanol 10%, potassium hydroxide 0.3% and water 11.7%.
[0055] The basic information of chemical additives involved in the present invention is as follows:
[0056] Isopropanolamine: Isopropanolamine is an important corrosion inhibitor that can be used in boiler water treatment, coolant for automobile engines, drilling and cutting oils, and other types of lubricating oils.
[0057] Nano-silicon corrosion inhibitor: one or more of aminopropyltriethoxysilane, aminopropyltrimethoxysilane, and aminopropylmethyldiethoxysilane, which can be used for metal cleaning and cutting fluid. It is used as an anti-corrosion agent in metal working lubricating fluids of aluminum, magnesium, zinc and other metals, and also has very good lubrication...
