In the following detailed description, specific details are set forth in order to provide a thorough understanding of the embodiments of the invention. However, it will be apparent that one or more embodiments may be practiced without such specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.
(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

(Constitution)
The structure of the gloss mat cosmetic sheet 10 will be described with reference to FIG.
As shown in FIG. 1, the gloss matte decorative sheet 10 includes a base material 1, a base resin layer 2, a pattern printing layer 3, and a surface protective layer 20. 2, the pattern printing layer 3, and the surface protective layer 20 are formed in this order.
The thickness of the gloss mat decorative sheet 10 is set, for example, within a range of 100 [μm] to 1000 [μm].

(Substrate 1)
The substrate 1 is formed using a material that is usually used as a paper substrate, such as a backing paper for a decorative sheet.
In the first embodiment, as the material of the substrate 1, the coating amount is in the range of 50 [g / m ² ] to 100 [g / m ² ], and the thickness is 80 [μm] to 150 [μm]. A case where plain paper within the following range is used will be described.
By using the plain paper having the above-described configuration as the material of the base material 1, it is possible to ensure the rigidity required as a wall covering material for the gloss mat decorative sheet 10.

(Base resin layer 2)
The base resin layer 2 is laminated on the base material 1. Note that “on the base material 1” represents the upper surface of the base material 1 in FIG. 1.
Moreover, the base resin layer 2 is applied using a coating method such as a knife coating method, a nozzle coating method, a die coating method, a lip coating method, a comma coating method, a gravure coating method, a rotary screen coating method, or a reverse roll coating method. And laminated on the substrate 1.

The base resin layer 2 can be provided on the upper surface of the base material 1 in a sheet shape or a pattern shape.
The coating amount of the base resin layer 2 is in the range of 50 [g / m ² ] to 150 [g / m ² ].
In addition, from the viewpoint of providing fireproof performance to the gloss mat decorative sheet 10, the total weight of the base material 1 and the base resin layer 2 is desirably 200 [g / m ² ] or less.

The base resin layer 2 which is a foamed resin layer is mixed with a foaming agent and foamed by heat treatment.
The expansion ratio of the base resin layer 2 is set in the range of 2 to 8 times. In the first embodiment, as an example, a case where the expansion ratio of the base resin layer 2 is set within a range of 4 times to 6 times will be described.

  By setting the coating amount and the expansion ratio of the base resin layer 2 to the above values, the gloss mat cosmetic sheet 10 having a sufficient volume feeling and an excellent surface strength to obtain the uneven surface concealing property is formed. Is possible. In addition to this, it is possible to form a gloss matte decorative sheet 10 capable of sharply reproducing the uneven shape of the surface by embossing (not shown) provided on the surface protective layer 20. In addition, the description regarding the embossing provided in the surface protective layer 20 is mentioned later.

  As a material for the base resin layer 2, a resin that can be used in the form of an aqueous emulsion, for example, a vinyl chloride resin or a polyolefin resin can be used. In addition, as the material of the base resin layer 2, in particular, among ethylene copolymers having monomers other than ethylene and ethylene (in the following description, “ethylene copolymer” may be described), It is preferable to use at least one kind.

  Further, as the material of the base resin layer 2, ethylene-vinyl acetate copolymer (EVA) resin, ethylene-methyl methacrylate copolymer (EMMA), and ethylene-ethyl acrylate copolymer (EEA) are preferably used. Is possible. In addition to this, as the material for the base resin layer 2, an ethylene-methyl acrylate copolymer (EMA), an ethylene methacrylic acid teaching fusion (EMAA), and an ethylene-α-olefin copolymer can be suitably used.

In addition, when using a vinyl chloride resin as the material of the base resin layer 2, the polymerization degree of the vinyl chloride resin is preferably 600 or more. This is because the surface strength of the gloss matte decorative sheet 10 can be increased by setting the polymerization degree of the vinyl chloride resin used for the base resin layer 2 to 600 or more.
As described above, the base resin layer 2 is formed using a thermoplastic resin including at least one of a vinyl chloride resin, a polyolefin resin, and an ethylene vinyl acetate copolymer resin.

The base resin layer 2 is appropriately mixed with a plasticizer, a foaming agent, a stabilizer (foaming stabilizer), a viscosity reducing agent, other organic additives, and an inorganic powder depending on the application.
The inorganic powder includes, for example, calcium carbonate, aluminum hydroxide, magnesium hydroxide, silica sand, talc, silicas, magnesium silicate, zinc borate, titanium dioxide and the like.
In addition, the inorganic powder is added within a range of 40 parts to 150 parts with respect to 100 parts of the resin. If the amount of inorganic powder added to 100 parts of the resin exceeds 150 parts, the non-flammability is improved, but the volume may be lowered.
Hereinafter, the foaming agent and the stabilizer mixed in the base resin layer 2 will be described.

(Foaming agent)
As the foaming agent, for example, it is generally used in known foamed cosmetic sheets such as thermally expandable microcapsule foaming agent, azo-based, hydrazide-based, nitroso-based, ADCA (azodicarbonamide foaming agent), sodium hydrogen carbonate and the like. It is possible to use a blowing agent.
As the foaming agent, a thermally expandable microcapsule foaming agent is preferable from the viewpoint of performance (foaming ratio, strength).

When ADCA and sodium hydrogen carbonate are used as the foaming agent, for example, ADCA and sodium hydrogen carbonate are in a ratio of 3: 1 to 1: 3, and the total of the two types is 100 parts of vinyl chloride resin. So that it is within the range of 1 part to 4 parts. As a result, it is possible to ensure the expansion ratio and prevent the foamed surface from being rough.
The amount of the foaming agent to be added depends on the thickness of the base resin layer 2 and the expansion ratio, but is in the range of 1 to 20 parts by weight, particularly 5 to 15 parts by weight with respect to 100 parts by weight of the resin. A degree within the range of parts or less is preferred.

(Stabilizer)
As the stabilizer, for example, the two types of stabilizers (barium salt type and zinc salt type) are in a ratio of 1: 4 to 4: 1, and the total of the two types is 1 with respect to 100 parts of the vinyl chloride resin. It mixes so that it may become in the range of 4 parts or more. This makes it possible to impart thermal stability and increase the foam thickness.
