Abstract

The invention discloses a normal temperature steel degreasing agent and a preparation method thereof. The normal temperature steel degreasing agent comprises, in terms of weight components: 3-6 parts of sodium hydroxide, 3-6 parts of sodium sulfate, and 0.5-1 part of sodium alginate , 0.2-1 part of sodium hexametaphosphate, 2-6 parts of lauric acid, 1-4 parts of triethanolamine, 0.5-1 part of sodium dodecylbenzenesulfonate, 1-3 parts of silicon dioxide, 0.2 parts of mono-diglyceride -0.8 parts, 5-10 parts of phosphoric acid, 1-4 parts of aluminum oxide, 70-80 parts of water; the preparation method is to add lauric acid and phosphoric acid into the container, raise the temperature to 65-70°C, and add aluminum oxide , after stirring and reacting, add silicon dioxide and mono-diglycerides, stir for 30-40 minutes, cool down to 50-60°C to obtain mixture 1; add water to another container, add the remaining components and mix well, and raise the temperature to 50-60°C; Stir and mix the above two mixtures, and cool down to room temperature to obtain room temperature steel degreaser.

Description

technical field [0001] The invention belongs to the technical field of preparation of metal surface treatment agents, and in particular relates to a normal temperature iron and steel degreasing agent and a preparation method thereof. Background technique [0002] Metal surface degreasing is a common process in metal processing or use. Commonly used metal cleaning agents are divided into solvent type, semi-solvent type and water-based type. Among solvent-based metal cleaners, petroleum solvents are flammable, explosive, and a waste of resources. Chlorofluorocarbons are the most commonly used solvent-based metal cleaners, but are banned due to their damage to the atmospheric ozone layer. Therefore, solvent-based metal cleaners are gradually being replaced by semi-solvent and water-based metal cleaners. Compared with the semi-solvent type, the application advantages of the water-based metal cleaning agent are more prominent. [0003] At present, medium-temperature or low-tem...
