Abstract

The invention discloses an environment-friendly decontamination and derusting agent for steel and a preparation method thereof, which is prepared from the following raw materials in parts by weight: 68-88 parts of deionized water, 10-14 parts of sodium tripolyphosphate, and 15 parts of pentaerythritol fatty acid ester ‑18 parts, 13‑16 parts of dodecenyl succinic acid, 5‑8 parts of konjac gum, 10‑14 parts of sodium alginate, 2‑6 parts of polyacrylamide, 2‑6 parts of potassium oxalate, dialkyl di Zinc thiophosphate 4‑10 parts, benzotriazole 5‑11 parts, ethylene glycol 22‑25 parts. The environment-friendly decontamination and derusting agent for steel prepared by the invention is non-toxic, environmentally friendly and energy-saving, and has little pollution to the environment; the derusting efficiency is high, and it can quickly remove oil stains, rust, oxide films, etc. on the metal surface; There is basically no over-corrosion and hydrogen embrittlement.

Description

technical field [0001] The invention relates to an environment-friendly steel decontamination and derusting agent and a preparation method thereof. Background technique [0002] Steel is the most used metal in human history, especially after entering industrialization, the demand for steel is increasing day by day. At present, the proven reserves of steel are very limited, and the amount of human mining remains high. If this pair of contradictions cannot be alleviated, it will largely restrict the further development of human beings. And the loss of steel due to corrosion every year is very alarming, resulting in the waste of a lot of resources. During the production process or the use of finished products, steel is easily oxidized and rusted when it encounters humid air and rainy days, which affects the appearance quality of the product. The easiest way to prevent steel from rusting is to isolate the steel from water and air, and keep the surface of the steel dry and clea...
