Method for preparing high-strength titanium and aluminum foil clad steel plate

Abstract

The invention provides a method for preparing a high-strength titanium and aluminum foil clad steel plate. The high-strength titanium and aluminum foil clad steel plate comprises a base plate, wherein a first chemical treatment layer is arranged on the upper side of the base plate, a second chemical treatment layer is arranged on the lower side of the base plate, and a back paint layer is arranged on the lower side of the second chemical treatment layer; a ground paint layer is arranged on the upper side of the first chemical treatment layer, a binder layer is arranged on the upper side of the ground paint layer, and an aluminum foil layer is arranged on the upper side of the binder layer; the upper side of the aluminum foil layer is covered with a PET film layer, and the upper side of the PET film layer is covered with a PE film; the base plate comprises a stainless steel plate, a titanium plate is arranged on the lower side of the stainless steel plate, a lower zinc coating is arranged on the lower side of the titanium plate, and an upper zinc coating is arranged on the upper side of the stainless steel plate; a lower aluminum foil cladding layer is arranged on the lower side of the lower zinc coating, and an upper aluminum foil cladding layer is arranged on the upper side of the upper zinc coating. The high-strength titanium and aluminum foil clad steel plate is reasonable and novel in structure, stable in quality and convenient to machine, and machining efficiency is use can be improved; furthermore, appearance is attractive, touch sense is good, and the high-strength titanium and aluminum foil clad steel plate can be widely applied to panels of various household appliances.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a method for preparing a high-strength titanium-gold-aluminum foil composite steel plate. Background technique [0002] Composite steel plates are widely used in industry and life, such as automobiles, refrigerators, washing machines, high-end furniture, kitchen equipment, industrial and civil buildings, etc., and the environments in which composite steel plates are used are becoming more and more special and extensive. Under a certain special environment, molecular migration will occur when the composite steel plate is in contact with other parts for a long time. Driven by this molecular migration phenomenon, the development of the composite steel plate industry will have a very broad space for development. [0003] The main structure of the aluminum foil film is divided into PET+aluminum foil. Because the surface of the aluminum foil has high gloss and the surface is smoo...

AI Technical Summary

Problems solved by technology

[0003] The main structure of the aluminum foil film is divided into PET+aluminum foil. Because the surface of the aluminum foil has high gloss and the surface is smooth and clean, after using glue to stick it to the substrate, the cupping adhesion is only 3mm, and the industry standard is ≧8mm, and the adhesion performance is unqualified , the actual production cannot meet the customer's molding requirements
