Abstract

The invention discloses a metal degreasing agent. The metal degreasing agent is composed of, by weight, 10-30 parts of potassium metasilicate, 5-20 parts of tolyl triazole, 15-20 parts of pyrrolidone,15-20 parts of sodium carbonate, 5-30 parts of water, 1-3 parts of triethanolamine, 1-3 parts of isopropanol and 1-3 parts of polyoxyethylene polyoxypropylene monobutyl ether. The metal degreasing agent is low in cost, simple in formula, suitable for being popularized and high in degreasing performance, and no residue exists after degreasing.

Description

technical field [0001] The invention belongs to the field of chemical agents, and more specifically relates to a metal degreasing agent. Background technique [0002] Degreasing agents are mainly used to remove oil on the surface of objects, including: alkaline degreasing agents, emulsion degreasing agents and solvent degreasing agents. (1) Alkaline degreasing agent, composed of alkali, chelating agent and surfactant, including compound high-efficiency degreasing agent, high-temperature strong degreasing agent, etc. (2) Emulsion degreasing agent, which can remove the dirt on the metal surface by using the wettability, penetrability, emulsification and dispersibility of the surfactant; generally use one of the anionic, cationic, nonionic and other surfactants One or several mixtures are diluted with water to make emulsion. (3) Solvent degreasing agent, degreasing by dipping method or steam method, the main solvents used are halogenated hydrocarbon solvents and fluorinated h...
