Metal oil dirt cleaning agent and preparation method thereof

Abstract

The invention discloses a metal oil dirt cleaning agent and a preparation method thereof and belongs to the field of cleaning agents. Based on styrene, butyl acrylate and crylic acid as main monomers,emulsion is modified, and good film forming performance, aging resistance, water resistance and salt mist resistance are achieved. The emulsion serves as the main component, an auxiliary agent for preventing corrosion of the metal surface is formed through compounding, film forming performance is good, a protective film can be formed on the metal surface after cleaning, a metal substrate can be well isolated from the outside environment, thus corrosion to the metal substrate is delayed effectively, and the metal surface is protected. The problems that at present, certain phosphorus-containingauxiliary agents and APEO surfactants are often added into metal oil dirt cleaning agents and cause large harm to the environment, the existing cleaning agents only have a cleaning function generallyand do not have a rustproof function, rustproof treatment is needed immediately after cleaning, time and labor are wasted, and cost is high are solved.

Description

technical field [0001] The invention belongs to the field of cleaning agents, and in particular relates to a cleaning agent for metal oil stains and a preparation method thereof. Background technique [0002] Metal cleaners are mainly used for cleaning in the production of parts. In surface treatment such as coating and electroplating, degreasing is an important process. The degree of degreasing on the surface of metal parts will directly affect the quality of subsequent treatment of workpieces. [0003] In modern production and life, metals are widely used in various important sectors such as construction, machinery, metallurgy, electronics, packaging, automobiles and high technology. They are not only functional materials but also structural materials, penetrating into various fields. [0004] In industrial production, even if metal parts do not undergo post-processing such as plating and other surface treatments, oil stains must be removed at a certain stage of production...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention: in view of the fact that some phosphorus-containing additives and APEO surfactants are often added to the current metal oil stain cleaning agent, these substances have great harm to the environment, and the existing cleaning agent generally only has cleaning function. However, there is no antirust function, and it is necessary to do antirust treatment immediately after cleaning, which is time-consuming, laborious, and costly. A metal oil stain cleaning agent and its preparation method are provided.
