Abstract

The invention provides a neutral rust-proof water-based cleaning agent. A raw material of the agent contains a phosphorus-free cleaning auxiliary agent, a metal corrosion inhibitor, a surfactant, a solubilizer, a defoaming agent and water. The invention further provides a preparation method of the neutral rust-proof water-based cleaning agent. According to the neutral rust-proof water-based cleaning agent, foam is low, a plurality of cleaning modes such as spray cleaning, ultrasonic cleaning and bubbling cleaning can be adopted, the application range is wide, the use method is flexible and diversified, the good cleaning effects on grinding oil, cutting fluid, metal powder and the like in the production and processing processes of various metal devices are realized, no influence is generated on subsequent surface treatment, and a certain rust-proof function is achieved; and the cleaning agent is easy to biodegrade and process and discharge, the compatibility with different metals is better, the cleaning and rust-proof performance are very high, the preparation process is simple, the preparation difficulty is reduced, and the manpower requirement is reduced.

Description

technical field [0001] The invention belongs to the technical field of industrial cleaning, and in particular relates to a neutral anti-rust water-based cleaning agent and a preparation method. Background technique [0002] Dirt and processing residues on the surface of metal workpieces after processing, such as various acids, alkalis, salts, dust, cutting fluids and various greases, etc. These dirt are water-soluble or insoluble, if not cleaned Cleaning will not only affect the smooth progress of the processing procedure, but also cause and accelerate the corrosion of the metal surface, affecting the processing quality and service life of the product. Before surface processing such as painting, glazing, electroplating and enamelling, it needs to be cleaned with cleaning agent. The quality of cleaning will directly affect the performance and quality of the product. Cleaning agent is an indispensable fine chemical product in industrial production, and its demand is increasi...
