Problems solved by technology

At present, chemical brighteners used in stainless steel hardware tools can be basically divided into five types: aqua regia solution, sulfuric acid solution, phosphoric acid solution, acetic acid solution and hydrogen peroxide solution. The brightener contains nitric acid, which will produce a large amount of harmful gases such as nitrogen oxides during polishing, thereby polluting the environment and endangering human health; while the hydrogen peroxide type polishing fluid is easy to decompose, difficult to maintain, high cost, and narrow application range.

Abstract

The invention discloses an environment-friendly reaction type polishing brightener composition and a preparation method and application thereof and belongs to the field of fine chemical engineering. The components of the environment-friendly reaction type polishing brightener composition comprises, by mass, 5%-10% of polishing agent, 3%-6% of alcohol amine, 3%-5% of complexing agent, 1%-4% of surface activating agent, 0.5%-2.0% of brightener, 0.1%-0.5% of thickening agent, 0.5%-2% of corrosion inhibitor, 1%-3% of pickling agent and 75%-85% of water. The environment-friendly reaction type polishing brightener composition prepared is an upgraded replacement product of a traditional brightener, the cleaning and brightening effects on a stainless steel material are obvious, no corrosion is caused to a base material, and the composition is environment-friendly.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and in particular relates to an environment-friendly reactive polishing brightener composition and its preparation method and application. Background technique [0002] Stainless steel has excellent properties such as high corrosion resistance, wear resistance, and easy processing. It is more and more widely used in industries such as automobiles, motorcycles, daily hardware, construction, and road guardrails. In recent years, the application of stainless steel has been increasing rapidly, but there is often a layer of gray oxide film or burrs on the surface, which affects the quality of the product. Therefore, polishing the surface of stainless steel is the most commonly used treatment process for stainless steel products. [0003] The brightener acts on the surface of the workpiece to cause microscopic plastic deformation, thereby reducing the surface roughness; the brightener acts on the surface...
