Problems solved by technology

In this way, it is easy to damage some metal surfaces with special decorative surface layers, or the appearance consistency of products produced under different temperature environments is poor.
Another shortcoming is especially reflected in the application of embossed metal plates. Embossed metal plates have a rich three-dimensional effect and special decorative effects. Using this technology to produce composite embossed bimetallic plates, due to the existence of embossed cavities, make The bonding surface of the polymer film is greatly reduced, and the bonding strength cannot be guaranteed
Limit the popularization and application of bimetallic composite panels

Abstract

The specification discloses a bimetallic composite plate material and a manufacturing process thereof; the bimetallic composite plate material comprises a surface layer metal and a bottom layer metal; a polyurethane adhesive layer is disposed between the surface layer metal and the bottom layer metal. The manufacturing process of the bimetallic composite plate material comprises the following steps: a. uniformly coating a polyurethane adhesive between the surface layer metal and the bottom layer metal; b. superposing the surface layer metal and the bottom layer metal; c. coating a protection film on the surface layer metal; d. performing normal temperature rolling compounding or heating rolling compounding of the surface layer metal and the bottom layer metal; e. shearing the plate; f. curing at a medium or low temperature.

Description

technical field [0001] The invention relates to a metal plate, in particular to a bimetal composite plate compounded with two metals. [0002] The present invention also relates to a plate manufacturing process, especially a manufacturing process for manufacturing the above-mentioned bimetallic composite plate. Background technique [0003] With social progress and rapid economic development, the contradiction of shortage of various mineral resources is becoming more and more prominent, especially various precious metal resources. In this context, how to use science and technology to improve resource utilization is particularly important. In the architectural decoration industry and light manufacturing industry, there is a huge demand for various metal sheets, such as copper, stainless steel, titanium, titanium zinc, and aluminum. However, in the actual application process, the existing technology is mainly aimed at utilizing the surface material characteristics and thickn...
