Problems solved by technology

[0002] Rust removal and rust prevention on metal surfaces has been widely concerned by people. There are two traditional methods of rust removal and rust prevention. One is to use manual or electric tools to remove rust. The construction is difficult, the cost is huge, and it is difficult to ensure the quality of rust removal. , the rust dust caused in the rust removal process pollutes the environment; the other is to use strong alkali to remove oil and strong acid to complete the two cleaning processes. The use of strong acid will cause great damage to the human body and pollute the air. In addition, the use of hydrochloric acid to clean will easily cause secondary corrosion in the atmosphere, which can only play a temporary corrosion inhibition role

preparation example Construction

[0013] The preparation method of the present invention comprises the steps:

[0014] (1) Mix phosphoric acid, sodium silicate, zinc dihydrogen phosphate and benzotriazole, then heat and stir until completely dissolved to prepare liquid A;

[0015] (2) Add γ-mercaptopropyltrimethoxysilane, triethanolamine oleate, APG, and sodium salt of α-sulfo fatty acid methyl ester into deionized water in sequence, then heat and stir until completely dissolved to prepare liquid B;

[0016] (3) Mix liquid A obtained in step (1) with liquid B obtained in step (2), and add sodium metasilicate pentahydrate, triethanolamine, sodium tripolyphosphate and citric acid in turn under stirring conditions, and stir well , to obtain an environmentally friendly rust-removing and anti-rust cleaner.

Abstract

The present invention relates to an environmental protection rust removing and rust resistance cleaning agent and a preparation method thereof, and belongs to the technical field of metal surface treatments. The cleaning agent comprises the following raw materials, by weight, 120-150 parts of deionized water, 5-10 parts of triethanolamine, 2-5 parts of citric acid, 20-25 parts of phosphoric acid, 4-6 parts of sodium silicate, 1-2 parts of zinc dihydrogen phosphate, 5-12 parts of sodium tripolyphosphate, 3-8 parts of 1H-benzotriazole, 8-10 parts of sodium metasilicate pentahydrate, 7-10 parts of gamma-mercaptopropyltrimethoxysilane, 2-4 parts of triethanolamine oleate, 1-5 parts of APG, and 2-4 parts of sodium alpha-sulfo fatty acid methyl ester. The environmental protection rust removing and rust resistance cleaning agent has characteristics of effective oil stain cleaning, rust removing, and good rust resistance. In addition, the barium-free rust resistance agent is adopted, and the components of the cleaning agent do not contain sodium nitrite and other toxic components, such that harms of strong bases and strong acids on the human body and the environment are concurrently avoided, and characteristics of safety and environmental protection are provided.
