Abstract

The invention discloses an antistatic color coating plate preparation process, which comprises: 1) preparing Sb doped SnO2 coated micro-nano TiO2 electric conduction powder by using a chemical co-precipitation method, wherein the concentration of a TiO2 slurry is controlled at 20-23%, SnCl4.5H2O accounts for 23-27% of the mass of TiO2, SbCl3 accounts for 10-12% of the mass of SnCl4.5H2O, the reaction temperature is controlled at 60+ / -2 DEG C, the pH value is controlled at 1.4+ / -0.1, the coating time is not less than 3 h, the calcination temperature is controlled at 500+ / -10 DEG C, and the calcination time is 3+ / -0.2 h; 2) mixing the electric conduction powder prepared in the step 1) and a polyester resin, heating to achieve a temperature of more than the melting point of the polyester resin, and extruding to obtain an antistatic resin tape; and 3) heating a metal plate to achieve a temperature of more than the melting point of the polyester resin, adhering the antistatic resin tape onto the metal plate, and cooling to obtain the antistatic color coating plate. According to the present invention, the antistatic color coating plate prepared by the preparation process has advantages of static electricity resistance, dust adsorption, and air purification.

Description

technical field [0001] The invention relates to a preparation process of an antistatic metal plate, in particular to a production process of an antistatic color-coated plate. Background technique [0002] At present, panels and walls made of ordinary steel plates are very prone to static electricity, especially in dry winter. As we all know, static electricity is a common physical phenomenon. In the past ten years, with the rapid development of integrated circuits and the wide application of polymer materials, the harm caused by electrostatic force, discharge and induction has become more and more serious. Preliminary statistics show that the annual loss of the US electronics industry due to electrostatic hazards is as high as more than 10 billion US dollars, the annual loss of British electronic products due to static electricity is about 2 billion pounds, and more than 45% of the substandard products of Japanese electronic components are due to electrostatic discharge.
