Hardware surface efficient rust remover and preparation method thereof

Abstract

The invention discloses a hardware surface efficient rust remover. The hardware surface efficient rust remover comprises the following raw materials of, by weight, 10-20 parts of acetic anhydride, 5-15 parts of hydrochloric acid, 3-9 parts of 1,3-butanediol, 3-9 parts of oleic acid, 1-4 parts of nanometer zirconium dioxide, 5-10 parts of nano cerium oxide powder, 1-2 parts of sodium dodecyl sulfate, 6-12 parts of Chinese honeylocust fruit powder, 4-12 parts of alkylphenol ethoxylate, 3-9 parts of matrine, 1-5 parts of sodium citrate, 80-100 parts of deionized water and 10-30 parts of ethanol. A preparation method of the hardware surface efficient rust remover comprises the following steps that (1) all the raw materials are weighed; (2) a solution A is prepared; (3) a solution B is prepared; and (4) mixing and standing are conducted. The hardware surface efficient rust remover is good in rust removal effect, short in rust removal time and capable of removing oil contamination and rust on the surface of metal, and the corrosion phenomenon does not occur to the metal. After rust removal, the surface of hardware is bright and is free of rust marks, smoke is not produced, usage is safe, the environment-friendly effect is achieved, and the hardware surface efficient rust remover is suitable for wide usage and popularization.

Description

technical field [0001] The invention relates to the field of rust removal on hardware surfaces, in particular to a high-efficiency rust remover for hardware surfaces and a preparation method thereof. Background technique [0002] Rust spots or stains of different sizes will be produced on the surface of the current hardware, which not only affects the appearance, but also is not conducive to subsequent mechanical processing. The commonly used rust removal method is to use acidic solvents to remove rust spots or stains. However, in the rust removal process, if the rust removal time is not well controlled, either the rust removal is not complete, or the rust removal time is too long and the hardware base material is corroded , produce traces on the surface of the hardware and damage the hardware itself. In addition, during the rust removal process using acidic solvents, the acidic solvents will volatilize and produce smog. At the same time, industrial three wastes will be pro...

[0002] The surface of the current hardware will produce rust spots or stains of different sizes, which not only affects the appearance, but also is not conducive to subsequent mechanical processing

The commonly used rust removal method is to use acidic solvents to remove rust spots or stains. However, in the rust removal process, if the rust removal time is not well controlled, either the rust removal is not complete, or the rust removal time is too long and the hardware base material is corroded , produce traces on the surface of the hardware and damage the hardware itself

In addition, during the rust removal process using acidic solvents, the acidic solvents will volatilize and produce smoke, and at the same time, industrial waste will be produced, which will have a certain impact on the health of workers
