Production process of aluminum-plastic plate

Abstract

The invention discloses a production process of an aluminum-plastic plate. The construction process comprises the following steps of forming a polyethylene layer with a preset width by adopting an extrusion process, respectively preheating surface aluminum and the preheated bottom aluminum, and respectively adhering polymer adhesive films to the preheated surface aluminum and bottom aluminum, where the widths of the polymer adhesive films, the surface aluminum and the bottom aluminum are all the preset widths; sending the extruded polyethylene layer and the surface aluminum and the bottom aluminum to which the polymer adhesive film is adhered into a group of composite rollers for compounding according to a preset up-and-down stacking sequence; and subjecting the compounded plate blank to roller pressing, cooling and fixed-length cutting. By adopting the production process, the use of heat energy is reduced, and the production speed is increased. A series of quality problems such as deformation, stretching and corrugated edges of the aluminum-plastic plate caused by uneven temperature of multiple groups of composite rollers are reduced, and the quality of the aluminum-plastic plateis improved. Waste of polyethylene layer materials is reduced, and production cost is saved.

Description

technical field [0001] The invention relates to the technical field of plate processing, and more specifically, relates to a production process of an aluminum-plastic plate. Background technique [0002] The upper layer of the aluminum-plastic panel is aluminum (referred to as surface aluminum), the middle layer is PE (polyethylene), and the lower layer is aluminum (abbreviated as bottom aluminum). It is compounded by polymer adhesive film after high-temperature heating, so it is also called aluminum-plastic composite. Board, suitable for interior and exterior wall decoration. The production of aluminum-plastic panels according to the traditional process is a relatively complicated process. After PE extrusion, three-roll calendering is required, and then preheating, polymer adhesive film, thermal compounding (requires four to six groups), cooling, and pasting. Protective film, cutting to length, etc. Since four to six sets of thermal lamination rollers are required in the ...
