Problems solved by technology

Additives can greatly improve the uniformity of plating solution adhesion, greatly reducing missing plating; make the interface between the liquid coating metal and the workpiece have better wettability; improve the uniformity and continuity of plating flux adhesion and prevent the occurrence of missing plating at the same time It can reduce the adhesion amount of plating flux and reduce the consumption of plating flux; after the workpiece is immersed in the flux, a special hydrophobic film is formed on the surface, which greatly shortens the drying time of plating flux and improves production efficiency; weakens the bursting strength of zinc liquid and prevents burns Reduce the risk of accidents and improve the working environment for workers; however, during the processing of the existing hot-dip metal plating, liquid metal splashes; the dipping time is prolonged, and the coverage is uneven, which affects the effect of hot-dip plating

Abstract

The invention discloses a multifunctional plating assistant additive for hot-dip metal plating and a preparation method thereof, which belongs to the technical field of corrosion prevention of metal materials, and aims to improve the wettability between liquid metal and a workpiece, improve plating assistant adhesion uniformity and continuity, and reduce drying time by by adding explosion-proof factors into traditional raw materials. By adding a ampholytic surfactant and a nonionic surfactant, liquid metal splashing can be effectively prevented, immersion plating time can be shortened, raw materials can be saved, the residue form can be improved, ash content can be reduced, ash discharge speed can be increased, air can be isolated, oxidation can be completely eradicated, and residual dirtcan be expelled. The multifunctional plating assistant additive is suitable for various processes such as hot galvanizing, hot galvanizing of aluminum alloy and hot aluminizing.

Description

technical field [0001] The invention relates to the technical field of anticorrosion of metal materials, in particular to a multifunctional plating flux additive for hot-dip metal plating and a preparation method thereof. Background technique [0002] Hot-dip galvanizing technology has become the most basic and most economical and effective method for the application of anti-corrosion steel materials. Hot-dip galvanizing is to immerse the rust-removed steel parts in the molten zinc at about 500 ° C, so that the surface of the steel components will be attached with a zinc layer, so as to achieve the purpose of anti-corrosion. The anti-corrosion mechanism is that the standard electrode potential of zinc is negative to that of iron, so the galvanized layer has the function of sacrificial anode protection of the steel base in water and humid air, which can greatly prolong the service life of the steel. [0003] The fluxing process is a necessary and important link in the hot-di...
