The invention relates to the technical field of plastic-steel composite boards, and discloses an electrostatic adsorption and high-temperature hot pressing combined process technology for a plastic-steel composite board. The technology comprises the following steps: a, taking a plastic-steel composite board as a raw material, enabling the outer layer of the plastic-steel composite board to pass through high-weather-resistance resin powder, and adopting an electrostatic adsorption technology to make static electricity generated by metal adsorb the high-weather-resistance resin powder to the plastic steel composite board. The electrostatic adsorption and high-temperature hot pressing combined process technology for the plastic-steel composite board is a novel production process, the produced product is the plastic-steel composite board, has the lightness of a metal plate and the corrosion resistance of high-weather-resistant resin, is complex and compact in structural combination, adopts high-weather-resistant engineering powder on the surface layer, and is cured at the high temperature of 330 DEG C, and no bonding layer is used for bonding with the metal board, so that the phenomenon that the surface layer falls off due to the fact that the bonding layer loses bonding force after being irradiated by ultraviolet rays for a long time, and the metal board is exposed in the atmosphere is avoided, and the composite board is safer to use.
Description
technical field [0001] The invention relates to the technical field of plastic-steel composite boards, in particular to a technology of combining electrostatic adsorption and high-temperature hot-pressing of plastic-steel composite boards. Background technique [0002] Existing anti-corrosion plates are lightweight anti-corrosion plates formed by laminating metal plates and resin films through high-temperature hot-pressing. Although the high-weather-resistant resin film covers the surface of metal plates to play an anti-corrosion effect, due to the high-temperature hot-pressing production process It is to bond the finished weather-resistant resin film to the plate. Under high temperature, ultraviolet rays or other bad weather conditions, it is very easy to cause the bonding layer between the high weather-resistant resin film and the metal plate to break, causing a wide range of resin films to fall off. Thereby can not reach anticorrosion, the effect of color retention. [0...
