Production process of aluminum-plastic plate

Abstract

The invention discloses a production process of an aluminum-plastic plate, and relates to the technical field of production and manufacturing of the aluminum-plastic plates. According to the technicalscheme, the production process is characterize by comprising the following steps that (1) mixing and stirring are performed; (2) extruding and piece making are performed; (3) aluminum plate degreasing is performed; (4) aluminum plate formation treatment is performed; (5) adhesive coating and compounding are performed; and (6) a protection film is compounded. According to the production process, the problem that the phenomenon of glue failure or falling off of an aluminum plate and a plastic core material due to poor bonding of the aluminum plate and the plastic core material is prone to occurrence during compounding of the aluminum plate and the plastic core material by using a polymer film is solved, the aluminum plate and the plastic core material are bonded and compounded by using adhesives, and air exhaust and dust removal operation is carried out so that the aluminum plate and the plastic core material can be tightly bonded, and glue failure or falling off of the aluminum plate and the plastic core material can be prevented.

Description

technical field [0001] The invention relates to the technical field of production and manufacture of aluminum-plastic panels, and more specifically, it relates to a production process of aluminum-plastic panels. Background technique [0002] As a modern, colorful, lightweight and durable new decorative material, aluminum-plastic panel is rapidly entering our lives. It has been widely used in various architectural decorations, such as ceilings, columns, counters, furniture , telephone booths, elevators, storefronts, billboards, dust-proof room wall materials, factory building wall materials, etc., have become the representative of metal curtain walls among the three major curtain walls (natural stone, glass curtain wall, metal curtain wall). The aluminum-plastic panel is made of aluminum foil plate as the surface layer and polyethylene plastic plate as the core layer, which is processed and compounded through a series of processes.

AI Technical Summary

Problems solved by technology

[0004] The existing production process of this aluminum-plastic panel is to use polymer film as an adhesive to compound the plastic sheet and the aluminum alloy layer, the cold shrinkage of the plastic sheet and the smoke generated during the manufacture of the plastic sheet , adhered to the surface of the plastic sheet, will cause poor adhesion between the plastic sheet and the upper aluminum alloy layer and the lower aluminum alloy layer, resulting in the plastic sheet and the upper aluminum alloy layer and the lower aluminum alloy layer being glued or even peeled off
