Problems solved by technology

[0008] In addition, the metal foil in the decorative metal plate is an extremely thin metal foil of 10 to 15 μm (refer to the "thickness" of "metal foil" in Table 1). Although the specific manufacturing method of the decorative metal plate is not described, if it uses Manufacturing such a wide decorative metal sheet was not conceived by a continuous manufacturing method using laminate rolls

Embodiment 1

[0068] Tables 1 to 6 show properties of samples (metal foil-laminated metal sheets) produced under various conditions in order to obtain the above-mentioned metal foil-laminated metal sheets of the present invention.

[0069] All of the metal sheets of the samples were hot-dip galvanized steel sheets subjected to chromate treatment as the surface treatment. Metal foil is stainless foil.

[0070] The binder used was the thermosetting polyester resin described in paragraph number [0019].

[0071] All the adhesive strength tests were performed by the 180 degreeC peeling test in 25 mm width based on JISZ0237.

[0072] In the expansion molding process for confirming the adhesive strength, a 6 mm extrusion was performed by the JIS Z 2247 Erichsen test method, and it was confirmed whether the stainless foil peeled off.

[0073] Table 1 shows the results of experiments for investigating the influence of lamination temperature. That is, the heating temperature of the metal plate is ...

Embodiment 2

[0087] Table 2 shows the experimental results for investigating the influence of the temperature of the lamination roll. That is, the experimental results of various samples obtained by laminating metal plates and stainless foils by changing the temperature of the lamination roll as a parameter in the range of 25°C to 200°C, and keeping other conditions approximately constant. .

[0088] In this case, regarding the metal plate, the thickness of the metal plate is mainly 0.4 mm (there are four other samples with a thickness of 0.6 to 1.2 mm), the thickness of the adhesive is 10 μm, and the heating temperature is mainly 150°C (other The temperature is 160°C, 180°C and 190°C each). Regarding the stainless foil, the plate thickness is 0.1 mm, and the adhesive thickness is 1 μm.

[0089] As shown in the column of adhesive strength in Table 2, when the temperature of the laminating roll was not 70° C., the adhesive strength in the peel test was less than 40 N, and the adhesive str...

Embodiment 3

[0099] Table 3 shows the results of experiments investigating the effect of the thickness of the metal sheet adhesive. That is, various experiments were made by laminating the metal plate and the stainless foil by changing the thickness of the adhesive applied to the metal plate as a parameter in the range of 4 μm to 20 μm, and keeping other conditions approximately constant. Such experimental results.

[0100] In this case, regarding the metal plate, the thickness of the metal plate is mainly 0.4 mm (there are 5 other samples having a thickness of 0.8 to 2.3), and the metal plate heating temperature is 150°C. Regarding the stainless foil, the plate thickness is 0.1 mm, and the adhesive thickness is 1 μm. The lamination roll temperature was 70°C.

[0101] As shown in the column of adhesive strength in Table 3, when the thickness of the metal plate adhesive is less than 10 μm, the adhesive strength is less than 40 N, so the adhesive strength is insufficient, and the result of...

Abstract

This metal sheet laminated with metal foil is formed by: placing, opposite each other, a thermosetting-adhesive-coated surface of each of a stainless steel foil having a thickness of 0.1 to 0.2 mm, to which a thermosetting adhesive has been applied in advance at a thickness of 1 to 5 mum and dried to the touch or is semi-cured, and a metal sheet to which a thermosetting adhesive with the same constituents as the aforementioned thermosetting adhesive has been applied with a coater at a thickness of 10 to 20 mum and heated to 150 to 250°C; and then feeding the stainless steel foil and metal sheet to a laminating roll so as to continuously bond said surfaces. The metal sheet laminated with metal foil is characterized in that the laminating adhesive strength of the stainless steel foil and the metal sheet is at least 50 N according to a peel test conducted at a width of 25 mm and 180°C.

Description

technical field [0001] The invention relates to a metal foil laminated metal formed by laminating stainless foil and steel plates and other metal plates, in particular to a metal foil laminated metal plate with excellent surface specularity and high metal foil bonding strength And a method of manufacturing a metal foil laminated metal sheet. Background technique [0002] Metal foil laminated metal sheet formed by laminating metal foil such as stainless foil and metal plate such as steel plate has the characteristics of metal plate such as steel plate with rigidity and good workability while exhibiting the excellent surface appearance of metal foil , and boards having these two characteristics can be produced cheaply, so they are used in construction materials such as interior decoration materials or exterior decoration materials of buildings, electronic and electrical equipment, transportation machines, and other various fields. [0003] As such a metal foil laminated metal...
