Abstract

The invention provides an oil removal powder for a metal surface. The oil removal powder comprises the following raw materials of, by weight, 20-30 g of sodium carbonate, 5-10 g of borax, 0.5-1 g of EDTA disodium, 8-10 g of washing assistant, 40-50 g of a metal protective agent and 2.5-7.5 g of a surfactant, wherein the surfactant comprises at least one of an anionic surfactant and a nonionic surfactant; the anionic surfactant is sodium alcohol ether sulphate; the nonionic surfactant comprises at least one of nonylphenol polyoxyethylene ether and fatty acid methyl ester ethoxylate; and the washing assistant is sodium citrate. A preparation method comprises the following steps of mixing sodium carbonate, borax and EDTA disodium, and carrying out uniform stirring so as to obtain a powder A;mixing the washing assistant and the metal protective agent, and carrying out uniform stirring so as to obtain a powder B; mixing the powder A and the powder B, adding the surfactant, and carrying outuniform stirring so as to obtain the finished product oil removal powder. The oil removal powder is high in oil removal capability and has good wetting, solubilizing and emulsification capabilities.

Description

technical field [0001] The invention belongs to the technical field of cleaning agents, and in particular relates to a degreasing powder for metal surfaces and a preparation method thereof. Background technique [0002] Oil removal powder is usually composed of caustic alkali, surfactant, sodium silicate and additives. It is a compound type of oil removal and degreasing agent, which mainly uses the saponification reaction of alkali in oil and the emulsification of surfactant. Function, through chemical cleaning methods such as wetting, penetration, roll-off, emulsification and dispersion, and under the action of electric current, a large number of bubbles are generated on the metal surface to peel off the dirt and emulsify and disperse the oil on the metal surface. [0003] The role of the surfactant is to reduce the surface tension of the lye. On the one hand, it can quickly infiltrate the lye to the metal surface to remove the dirt. On the other hand, it can emulsify and d...
