Hot galvanizing antiknock agent and preparation method thereof

Abstract

The invention discloses a hot galvanizing antiknock agent and a preparation method thereof. The hot galvanizing antiknock agent comprises the following raw materials of, in percentage by weight, 20%-35% of ionic liquid, 1%-20% of a nonionic surfactant, 1%-3.5% of a diamide compound, 35%-50% of an organic solvent and 1%-10% of deionized water, in a hot galvanizing process, the antiknock agent is directly added into a plating assisting agent solution, and the mixture is uniformly stirred and used at 60-75 DEG C. The antiknock agent is suitable for plating assisting treatment of various processes such as hot galvanizing, hot galvanizing aluminum alloy, hot galvanizing aluminum and the like, the surface tension between the plating assisting agent and a workpiece can be effectively reduced, the plating assisting effect is improved, the surface quality of a galvanized layer is improved, the zinc immersion time is shortened, the surface glossiness of the galvanized layer is improved, liquid metal splashing caused by residual liquid on the surface of the workpiece in the immersion plating process is prevented, the usage amount of a plating assisting agent is reduced, the adhesion amount of the plating assisting agent on the surface of the workpiece is reduced, zinc slag is reduced, solvent smoke and solvent ash are reduced, and the environment is improved.

Description

technical field [0001] The invention relates to the technical field of hot-dip galvanizing, in particular to a hot-dip galvanizing explosion-proof agent and a preparation method thereof. Background technique [0002] Hot-dip galvanizing is one of the most effective means to delay the corrosion of steel materials. Compared with other metal protection methods, the hot-dip galvanizing process combines the physical barrier and electrochemical protection of the coating. The combination of the coating and the substrate It has incomparable advantages in terms of strength, compactness, durability, maintenance-free and economical efficiency of the coating, and its adaptability to the shape and size of the product. Solvent-assisted plating is an important process in the pre-treatment of hot-dip galvanizing. It can not only make up for the deficiencies in the previous processes, but also further activate the steel surface and improve the quality of galvanizing. This is unmatched by ot...

Problems solved by technology

However, there are still problems such as unsafe working environment for workers, poor stability of additives, environmental protection cannot be guaranteed, non-recyclable, and limited application range, etc.

Ionic liquid is an ionic system composed of anions and cations that is liquid at room temperature (or slightly higher than room temperature). It has the advantages of good wettability, stable chemical properties, green and pollution-free, and reusable. The defects of the above-mentioned prior art, but it has not been applied to the hot-dip galvanizing industry at present
