Rust-proof cleaning agent for metal products

Abstract

The invention relates to a rust-proof cleaning agent for metal products. The rust-proof cleaning agent comprises, by weight, 10-15% of glycolic acid, 28-35% of polyhydric alcohol phosphate ester, 2-5% of anionic surfactant, 10-15% of toluic acid, 1-3% of reducing agents, 10-15% of propylene glycol monoethyl ether, 5-8% of urea, 8-15% of defoaming agents and 8-12% of N-methyl-2-pyrrolidone. According to the rust-proof cleaning agent for the metal products, the N-methyl-2-pyrrolidone serves as cleaner and solubilizer, the biological degradability is good, and the urea can remove spot films of metal; all the ingredients are combined effectively, an excellent synergetic enhancement effect can be produced, and the rust-proof cleaning agent for the metal products has a good rust-proof effect and is low in average cleaning cost and good in safety performance.

Description

technical field [0001] The invention relates to the surface treatment technology of metal products, in particular to an antirust cleaning agent for metal products. Background technique [0002] Metal products often appear in factories or households. These metal products will appear rust spots after a long time of use. The surface treatment includes machining, phosphating, painting, electroplating, etc. The surface treatment of metal parts must first put the metal parts The oil stain on the surface is removed, and then effective spray cleaning is carried out. The traditional method is mainly to use gasoline or kerosene for cleaning. The advantage of this method is that it has a strong ability to remove oil and degrease the surface of metal parts, and the cleaned workpiece is not easy to rust after normal air drying. But the problem that this method exists is: the gasoline or kerosene cleaning agent used has flammable characteristics, and the operation process is extremely un...
