Method for preparing PE colored-texture decorative surface aluminum-plastic plate

Abstract

The invention discloses a method for preparing a PE colored-texture decorative surface aluminum-plastic plate. The method comprises the following three steps of: carrying out coating with an adhesiveafter polishing the surface of an aluminum-plastic plate, carrying out roll-pressure with a PE colored-texture film, and carrying out vacuum centrifugation on the semi-finished product of the aluminum-plastic plate, wherein the component material of the adhesive is composed of the following raw materials: tween-20, acrylic resin, epoxy resin, dibutyl phthalate, ethylene glycol, polyacrylamide, carbomer resin, amino polyamide, and the balance of ethyl acetate. The dibutyl phthalate has a defoaming property, so that the intermolecular forces of a polymer can be effectively reduced, and the flowability of the adhesive can be increased; the ethylene glycol has a certain anti-freezing property, so that the adhesive is promoted to be not denatured at a low temperature; and the component materials are matched with each other and mutually exert a synergistic effect to improve the high temperature resistance, the compressive strength and the stability of the PE colored-texture decorative surface aluminum-plastic plate.

Description

technical field [0001] The invention relates to the field of architectural decoration, in particular to a method for preparing an aluminum-plastic panel with a PE color pattern finish. Background technique [0002] As a new type of decorative material, aluminum-plastic composite panels (also known as aluminum-plastic composite panels) have been introduced to China from Germany since the late 1980s and early 1990s. The construction method, excellent processing performance, excellent fire resistance and noble quality are quickly favored by people. Aluminum-plastic panels are mainly used for building exterior walls, curtain wall panels, refitting and renovation of old building exterior walls, balconies, equipment units, indoor compartments, panels, sign boards, display stands, industrial materials, body of cold-insulation vehicles, Air conditioners, TV sets and other home appliance shells, etc. Therefore, aluminum-plastic panels are widely used in daily life and production pr...
