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.
