Abstract

The invention discloses a metal surface treating agent which consists of the following raw materials in parts by weight: 15-20 parts of sodium polyacrylate, 2-4 parts of trifluoroethanol, 2-4 parts of nonylphenol polyoxyethylene ether, 2-4 parts of sodium citrate, 4-6 parts of EDTA tetrasodium, 4-6 parts of chitosan, 4-6 parts of sodium dodecyl sulfate, 3-5 parts of acetic acid, 3-5 parts of ethylene glycol, 3-5 parts of triethanolamine, 3-5 parts of di-o-tolyl-thiourea, 3-5 parts of sodium gluconate, 3-5 parts of carboxymethyl cellulose, 3-5 parts of sodium oleate, 3-5 parts of sodium pyrophosphate, 3-5 parts of silicon dioxide, 3-5 parts of a nonionic surfactant, 4 parts of an anionic surfactant, 4 parts of a defoaming agent and 4 parts of a stabilizer, wherein the anionic surfactant is selected from one or more of octaphenyl polyoxyethyiene, higher aliphatic alkanol polyoxyethylene ether, polyoxyethylene stearate and sorbitan ether. The metal surface treating agent disclosed by the invention is good in cleaning effect.

Description

technical field [0001] The invention relates to a treatment agent, more particularly to a metal surface treatment agent and a preparation method thereof. Background technique [0002] Metal is a shiny, malleable, easily conductive, thermally conductive substance. In nature, most metals exist in a compound state, and a few metals such as gold, platinum, silver, and bismuth exist in a free state. Metal minerals are mostly oxides and sulfides. Other forms are chlorides, sulfates, carbonates and silicates. Different degrees of oxidation and corrosion often occur in the process of metal processing, handling and use, which reduces the service life of metal materials or metal equipment. Therefore, it is necessary to treat the metal surface to increase its anti-oxidation and anti-corrosion capabilities service life. At present, metal cleaning agents are generally used to clean metal surfaces, but most of the metal cleaning agents currently on the market have poor cleaning effect...
