Abstract

The invention relates to a safe, environment-friendly and rust-proof neutral rust remover and a preparation method thereof. The safe, environment-friendly and rust-proof neutral rust remover comprisesthe following components: 20-30% of 1-hydroxyethylidene-1, 1-diphosphonic acid, 2-5% of inositol hexaphosphate, 10-15% of polyacrylic acid, 3-5% of ethylene diamine tetraacetic acid, 5-10% of potassium hydroxide, 1-2% of urotropin and 33-59% of purified water. The safe, environment-friendly and rust-proof neutral rust remover is prepared by scientifically compounding multiple penetrating agents,complexing agents and powerful active components, and can quickly remove rust layers and oxides on the metal surface at normal temperature; the surface of a workpiece after rust removal has a short-term rust-proof function; such heavy rust removal methods as polishing and sand blasting are replaced; the surface of the workpiece is not damaged; and the machining precision is not influenced.

Description

technical field [0001] The invention belongs to the field of rust removal and anti-rust, relates to various industries that need rust removal and anti-rust machining equipment and workpieces, in particular to a safe, environment-friendly, anti-rust and anti-rust neutral rust remover and a preparation method thereof. Background technique [0002] With the development of my country's economy and the improvement of people's living standards, industrial products are vigorously developed. In my country's water resources, groundwater is a very precious resource. more and more widely developed and applied. However, due to the high iron content in groundwater due to the rocky nature of nature itself, the metal surface is often corroded during use, especially with the vigorous development of the manufacturing industry, carbon steel or cast iron mechanical parts produced by various industries are in storage Or corrosion occurs during transportation, which not only affects the beauty o...
