Problems solved by technology

[0007] On the other hand, in recent years, from the viewpoint of reducing the weight of metal plates, imparting sound absorption properties, imparting vibration damping properties, and imparting heat insulation properties, decorative metal plates combining metal plates and plastic sheets have been developed. It has been widely used in the field of home appliances and weak currents of various home appliances and AV equipment. When this laminated composite is used to coat parts that have undergone secondary processing such as bending, piercing, cutting, and deep drawing, the following will occur. The problem is that the molten resin flows out from the cutting part and the piercing processing part, which hinders the post-processing. The molten resin shrinks greatly during the cooling and solidification process, so the vicinity of the cutting processing part will be deformed.

Embodiment 1

[0072] Co-extruded polypropylene resin modified with maleic anhydride (modification rate 0.8% by weight, tensile stress at 5% elongation is 80MPa) and polypropylene resin (tensile stress at 5% elongation is 120MPa) and made into thin slices. The thickness of the modified polypropylene is 20 μm, and the thickness of the polypropylene is 20 μm. Corona treatment (6KW, processing speed 20m / min) was performed on the polypropylene resin side of the obtained sheet to adjust the surface tension to 45dyne / cm or more, and then a polyester-based adhesive (Dainichi Seika Co., Ltd.: Seikabond E295 ), dry-laminated with 50 μm-thick aluminum foil that has been subjected to hairline processing. A light black transparent polyurethane resin ink was applied to the aluminum foil by gravure printing, and then, a 25 μm-thick polyester adhesive (Dainichi Seika Co., Ltd.: Seikabond E295) was dry laminated on the printed surface. A polyester film (manufactured by Toyobo) was used to provide a transp...

Embodiment 2

[0082] In Example 1, a hairline-processed polypropylene film having a thickness of 30 μm was used to carry out 500 A decorative steel sheet was obtained in the same manner as in Example 1 except that the polypropylene film treated with the aluminum evaporation film was replaced with the 50 μm-thick aluminum foil processed by hairline processing.

Embodiment 3

[0084] A polypropylene resin modified with maleic anhydride (modification ratio: 0.8% by weight, tensile stress at 5% elongation: 80 MPa) was extruded to form a sheet. The thickness of the flakes was 30 μm. Corona treatment (6KW, processing speed 20m / min) was carried out on one side of the obtained sheet, the surface tension was adjusted to be more than 45dyne / cm, and then a polyester-based adhesive (Dainichi Seika Co., Ltd.: Seikabond E295) was used, Dry lamination is carried out with 50 μm thick aluminum foil with hairline processing. A light black transparent polyurethane resin ink was applied to the aluminum foil by gravure printing, and then, a 25 μm-thick polyester adhesive (Dainichi Seika Co., Ltd.: Seikabond E295) was dry laminated on the printed surface. A polyester film (manufactured by Toyobo) was used to provide a transparent resin layer.

[0085] Next, an ionizing radiation-curable resin paint (composition shown below) was applied on the transparent resin layer ...

Abstract

The invention relates to a decorate sheet with metallic color. Wherein, it is formed by modified polyolefin resin layer, metal foil layer, and transparent film layer which selects at least one of modified polypropylene, polyethylene and ethene-propone rubber as main component that passed with non-saturated carboxylic acid or non- saturated carboxylic acid derivate, while the extending stress at 5% length is 25-500MPa. Therefore, the inventive sheet will not flow resin at the section in cutting or holing process.

Description

technical field [0001] The present invention relates to a metallic color decorative sheet which can be used as a surface material for house interior decoration such as kitchen doors, storage doors, etc., and as a surface material for home appliances such as refrigerators, etc., and to provide the surface with a metallic color pattern design, and A decorative metal plate using this sheet. Background technique [0002] Conventionally, as surface materials for such residential interior materials, home appliances such as refrigerator doors, and kitchen doors, there are painted steel sheets coated on metal sheets, and vinyl chloride films filled with metal powder. A decorative sheet made of polyester film is attached to a decorative metal plate on a steel plate with an adhesive. In the coated steel sheet, the coating film peels off during processing, or cracks are caught in the coating film, which may cause problems in workability, or easily cause damage to the coating film. ...
