Abstract

A water based antirust cleaning agent disclosed in the invention, comprises surfactant, water based passivant, builder, antifoaming agent and water. The cleaning agent features simple formulation, being easy to operate, good cleaning function on oil on a workpiece surface in metal processing, little foam in cleaning process and long service life, forms an antirust film on the workpiece surface after cleaning to realize rust protection during the process, and solves a technological bottleneck in the field of chemical cleaning agent, making an ideal balance between the performance of cleaning and antirust. The cleaning agent contains no ODS (ozone depletion substances), phosphate and nitrite, belonging to an environment-friendly product.

Description

technical field [0001] The invention relates to the field of industrial cleaning agents, in particular to an antirust cleaning agent in metal processing and a preparation method thereof. Background technique [0002] Water-based cleaning agent is a product with cleaning ability formulated with surfactant as the main component plus additives and other additives. As we all know, cleaning performance and antirust performance are two important indicators for evaluating the quality of cleaning agent products, but the two are a pair of contradictions. If the cleaning effect is good, the anti-rust between processes is not ideal, and if the anti-rust effect is ideal, the cleaning rate will decrease. This is the technical bottleneck of existing cleaning agent products, which has been perplexing workers in this technical field always. Since I have been engaged in this field, many manufacturers have reported that the cleaning agent products they use will rust in a short period of tim...
