The application relates to the technical field of cold-rolled strip steel production, in particular to a preparation method of hot-dip galvanized steel. The method comprises the following steps: annealing a cold hard plate and controlling process parameters of the annealing; performing hot-dip galvanizing on the cold hard plate after annealing and controlling a furnace nose dew point in the hot-dip galvanizing process to obtain first hot-dip galvanized steel; performing surface flattening on the first hot-dip galvanized steel and controlling process parameters of the surface flattening to obtain hot-dip galvanized steel. The method has simple process control, solves the problem of poor uniformity of the zinc layer thickness on the surface of the cold-rolled galvanized production strip steel, and provides guarantee for product quality of a subsequent production line.

The invention provides an electrogenerated viscosity-reducing adhesive as well as a preparation method and application thereof. The electro-induced viscosity-reducing glue comprises modified acrylate resin, the PDI of the modified acrylate resin is larger than 2.5 and smaller than 5, the weight-average molecular weight of the modified acrylate resin is 300,000-800,000, and the electro-induced viscosity-reducing glue using the modified acrylate resin is wide in PDI range, a low-molecular-weight part can be preferentially ionized or polarized, an electric field is rapidly responded, and the adhesive force is triggered to be reduced; the high-molecular-weight part can maintain the integrity of the material, excessive softening or breakage of the adhesive layer in the electrical stimulation process is avoided, and meanwhile, the weight-average molecular weight is within 300,000-800,000, and the bonding strength in the adhesive layer can also be improved; pDI and weight-average molecular weight are matched, so that the normal-temperature retention time can be prolonged. Therefore, the electrogenerated viscosity-reducing glue is short in debonding time, the normal-temperature retention time is prolonged, the initial adhesion strength is high, and the glue layer is prevented from being excessively softened or broken in the electrical stimulation process.
