(C), (d) is a schematic diagram for demonstrating the manufacturing method of the decorative molded product using the laminated body for decorative shaping | molding (protective film) of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
First, the protect film of the present invention will be described.
The protective film of the present invention comprises a base film and an adhesive layer laminated on one side thereof, and the base film is made of a vinyl chloride resin composition containing a vinyl chloride resin and a plasticizer, and has a thickness. Is 100 to 200 μm.
In the method of manufacturing a decorative molded product, the protective film includes a step of attaching a decorative film softened by heating using a hot plate provided with a vent to the surface of the core material. It is used by interposing it between the plates.

FIG. 1 is a cross-sectional view schematically showing an example of the protective film of the present invention.
As shown in FIG. 1, the protective film 10 of the present invention is obtained by laminating a pressure-sensitive adhesive layer 12 on one side of a base film (first base film) 11, and the base film 11 is made of vinyl chloride. It consists of a resin composition (first vinyl chloride resin composition) and has a thickness of 100 to 200 μm.

The first vinyl chloride resin composition contains a vinyl chloride resin and a plasticizer.
Examples of the vinyl chloride resin include vinyl chloride homopolymers and copolymers of vinyl chloride and other monomers copolymerizable therewith.
Examples of the other copolymerizable monomers include vinyl esters such as vinyl acetate and vinyl propionate, olefins such as ethylene, propylene, and styrene, methyl acrylate, ethyl acrylate, and methyl methacrylate. ) Acrylic acid esters, maleic acid diesters such as dibutyl maleate and diethyl maleate, fumaric acid diesters such as dibutyl fumarate and diethyl fumarate, vinyl cyanide such as acrylonitrile and methacrylonitrile, vinylidene chloride and vinyl bromide Examples thereof include vinyl ethers such as vinyl halide, methyl vinyl ether, and ethyl vinyl ether. These may be used alone or in combination of two or more.

The content of the other copolymerizable monomer in the copolymer is usually 50% by weight or less, preferably 10% by weight or less.
Among the vinyl chloride resins, a vinyl chloride homopolymer is preferable from the viewpoint of excellent dimensional stability.

The average degree of polymerization of the vinyl chloride resin is preferably 700 to 1000.
If the said average degree of polymerization is less than 700, it may be inferior to a moldability (following property with respect to a core material). On the other hand, if the average degree of polymerization exceeds 1000, the moldability (followability to the core material) is good, but after forming, the formation of vacuum marks on the surface of the decorative film (decorative surface) is suppressed. Performance as a protective film (hereinafter, such performance is also referred to as protective property) may be insufficient, and as a result, vacuum marks may be conspicuous on the surface of the produced decorative molded product. .
In the present invention, the average degree of polymerization of the vinyl chloride resin means the average degree of polymerization measured in accordance with JIS K-6721 “Testing method for vinyl chloride resin”.

As said plasticizer, that whose molecular weight is 350-3000 is preferable.
When the molecular weight is less than 350, the plasticizer tends to bleed from the base film 11, and when the plasticizer bleeds and moves to the adhesive layer, the adhesive strength of the adhesive layer may be reduced.
On the other hand, when the molecular weight exceeds 3000, the flexibility at low temperature is lowered and the moldability to the core material may be inferior.

In the present invention, when the plasticizer is made of a polymer compound, the molecular weight is a number average molecular weight, and the number average molecular weight is a measured value in terms of polystyrene by GPC (gel permeation chromatography) measurement.
The GPC measurement is performed according to a standard method. A dilute tetrahydrofuran solution of a plasticizer to be measured was prepared and measured using a GPC measuring device “HLC-8220GPC” manufactured by Tosoh Corporation under a flow rate condition of 0.6 ml / min. As the column, “KF606M” and “KF603” manufactured by Showa Denko KK were used.

Specific examples of the plasticizer include phthalic acid diesters such as octyl phthalate (di-2-ethylhexyl phthalate (DOP)), dibutyl phthalate and dinonyl phthalate, cyclohexane dicarboxylic acid ester, dioctyl adipate, and sebacic acid. Examples include aliphatic dibasic acid diesters such as dioctyl, phosphoric acid triesters such as tricresyl phosphate and trioctyl phosphate, epoxy plasticizers such as epoxidized soybean oil and epoxy resins, and polymer polyester plasticizers. .
Examples of the polymer polyester plasticizer include polyalkylene glycol diesters such as polyethylene glycol diester, polypropylene glycol diester, and polyethylene glycol polypropylene glycol diester of phthalic acid, and polyethylene glycols of aliphatic dibasic acids such as adipic acid and sebacic acid. Examples include polyalkylene glycol diesters such as diesters, polypropylene glycol diesters, and polyethylene glycol polypropylene glycol diesters.
These may be used alone or in combination of two or more.

The blending amount of the plasticizer is preferably 5 to 20 parts by weight with respect to 100 parts by weight of the vinyl chloride resin.
When the blending amount of the plasticizer is less than 5 parts by weight, the flexibility of the film may be insufficient, and it may not be possible to deform following the shape of the decorated surface of the core material during molding. On the other hand, if it exceeds 20 parts by weight, the followability at the end of the core material is lowered, and the attached decorative film is easily peeled off at the end of the core material.

  The first vinyl chloride resin composition may further contain an inorganic filler. By containing an inorganic filler, the heat resistance of the protective film can be improved.

  Examples of the inorganic filler include inorganic fillers made of calcium carbonate, titanium oxide, silica, kaolin, bentonite, talc, carbon black, iron oxide, aluminum hydroxide, magnesium hydroxide, and the like.

The amount of the inorganic filler is preferably 40 parts by weight or less with respect to 100 parts by weight of the vinyl chloride resin.
When the blending amount of the inorganic filler exceeds 40 parts by weight, the protective film (first base film) is too hard, and when it is applied to the core material as a decorative molding laminate, the surface shape of the core material is changed. Further, the decorative film cannot be followed, and the decorative film may be deformed to obstruct the surface shape of the core material.
On the other hand, a preferable lower limit of the amount of the inorganic filler is 10 parts by weight with respect to 100 parts by weight of the vinyl chloride resin. When the blending amount of the inorganic filler is less than 10 parts by weight, it is difficult to receive the effect of including the inorganic filler.

  The first vinyl chloride resin composition is a variety of stabilizers, colorants, foaming agents, lubricants, modifiers, diluents and the like that are generally used in vinyl chloride resin compositions as needed. An additive may be contained.

The base film 11 has a thickness of 100 to 200 μm.
When the thickness is less than 100 μm, when the surface of the core material is decorated, even if it is interposed between the decorative film and the hot plate, the hot plate is provided in the decorative film. It is impossible to prevent the pore shape from being transferred.
On the other hand, if the thickness exceeds 200 μm, the surface shape of the core material cannot be followed, and the decorative film will be inhibited from following the surface shape of the core material.

  The 10% modulus of the first base film 11 constituting the protect film 10 is preferably 0.4 to 5.0 (N / 25 mm). If it is less than 0.4 N / 25 mm, since the film is too soft against heat, the through hole of the hot plate may be transferred. On the other hand, if it exceeds 5.0 N / 25 mm, moldability may be insufficient.

An adhesive layer 12 is laminated on one side of the base film 11.
The pressure-sensitive adhesive layer 12 is formed using, for example, an acrylic pressure-sensitive adhesive containing an acrylic polymer.
Examples of the acrylic polymer include homopolymers of (meth) acrylic acid alkyl esters or copolymers thereof, and copolymers of (meth) acrylic acid alkyl esters and copolymerizable monomers. It is done. Among these, a copolymer of (meth) acrylic acid alkyl ester is preferable.

  Specific examples of the acrylic polymer include a copolymer composed of 2-ethylhexyl acrylate and acrylic acid, a copolymer composed of 2-ethylhexyl acrylate and hydroxyethyl acrylate, and composed of 2-ethylhexyl acrylate and methyl methacrylate. Copolymer, copolymer composed of 2-ethylhexyl acrylate, 2-methoxyethyl acrylate and vinyl acetate, copolymer composed of 2-ethylhexyl acrylate and vinyl pyrrolidone, 2-ethylhexyl acrylate, methyl methacrylate and 2-methoxyethyl Examples thereof include a copolymer composed of acrylate, a copolymer composed of 2-ethylhexyl acrylate, vinyl pyrrolidone and acrylic acid. These may be used alone or in combination of two or more.

The pressure-sensitive adhesive layer may further contain a curing agent, a tackifier, a known additive, and the like.
Examples of the curing agent include an isocyanate curing agent and an epoxy curing agent.

The protective film 10 preferably has a smooth surface (surface facing the hot plate during the production of the decorative molded product) and back surface (surface on which the adhesive material layer is laminated).
When the front and back surfaces of the protective film have irregularities, the irregularities are transferred to the decorative film, and when the decorative molded product is manufactured, the appearance of the obtained decorative molded product may be inferior.

In the method of manufacturing a decorative molded product, the protective film includes a step of attaching a decorative film softened by heating using a hot plate provided with a vent to the surface of the core material. A decorative molded product having a good appearance can be produced by using the protective film by interposing it between the plates (laminated on the decorative film).
A method for producing a decorative molded product using the protect film of the present invention will be described later.

Next, the decorative molded laminate of the present invention will be described.
The laminate for decorative molding of the present invention includes a decorative film and the protective film of the present invention laminated on the decorative film, and the decorative film is made of the second vinyl chloride resin composition. A second base film and an adhesive layer laminated on one side of the second base film.
FIG. 2 is a cross-sectional view schematically showing an example of the decorative molding laminate of the present invention.

As shown in FIG. 2, the decorative molded laminate 1 of the present invention includes a decorative film 20 and a protect film 10 laminated on the decorative film 20.
In the decorative film 20, an adhesive layer 22, a second base film (decorative film base) 21, and a printing layer 23 are laminated on the separator 24 in this order.
The protect film 10 is as already described.

The second base film 21 is made of the second vinyl chloride resin composition.
The second vinyl chloride resin composition contains a vinyl chloride resin and a plasticizer.
Specific examples of the vinyl chloride resin include those similar to the vinyl chloride resin contained in the first vinyl chloride resin composition. A preferred vinyl chloride resin is a vinyl chloride homopolymer from the viewpoint of excellent printability and visibility, and further excellent dimensional stability.
Specific examples of the plasticizer include the same plasticizers as those contained in the first vinyl chloride resin composition.

The vinyl chloride resin contained in the second vinyl chloride resin composition preferably has an average degree of polymerization of 700 to 1400.
In this case, it is excellent in printability (for example, coloring property at the time of printing, ink fixing property, etc.) when a printing layer is formed using a solvent-based ink. On the other hand, if the average degree of polymerization is less than 700, the solvent-based ink is excessively absorbed, and the ink oozes out in a swollen state in the film, so that the color development and sharpness during printing are insufficient. May be. On the other hand, when the average degree of polymerization exceeds 1400, the solvent-based ink has a low absorbability, the ink hardly penetrates into the film, and adheres to the surface of the film. May be impaired.

The plasticizer contained in the second vinyl chloride resin composition preferably has a molecular weight of 350 to 3000.
When the molecular weight is less than 350, it is easy to bleed from the second base film, and when the plasticizer bleeds, it moves to the adhesive layer and decreases the adhesive strength of the adhesive layer, or moves to the surface of the base film. When printing layers are formed, printing unevenness may occur.
On the other hand, when the molecular weight exceeds 3000, the plasticizer absorbs ink too much, and an image formed on the printing layer may be blurred, resulting in poor printing layer sharpness.

In the second vinyl chloride resin composition, the amount of the plasticizer is preferably 5 to 30 parts by weight with respect to 100 parts by weight of the vinyl chloride resin.
When the blending amount of the plasticizer is less than 5 parts by weight, the absorbability of the solvent-based ink of the second base film becomes insufficient, so that bleeding occurs and the printing suitability of the solvent-based ink may be inferior. Moreover, if it is less than 5 weight part, the followable | trackability to a core material becomes inadequate and it may be inferior to a moldability. On the other hand, when the amount exceeds 30 parts by weight, the second base film becomes too soft. In this case, when the surface to be decorated is decorated with a curved core, the attached decorative film is peeled off from the core. May end up.

  The second vinyl chloride resin composition is a stabilizer, a colorant, a foaming agent, a lubricant, a modifier, inorganic particles or inorganic fibers that are generally used in vinyl chloride resin compositions as required. It may contain various additives such as inorganic fillers and diluents.

The thickness of the second base film 21 is preferably 50 to 500 μm.
If the thickness of the 2nd base film 21 is less than 50 micrometers, the intensity | strength of a film is inadequate and it may be inferior to decorative moldability. On the other hand, if it exceeds 500 μm, it may be impossible to follow the surface shape of the core material.

The print layer 23 is composed of an image such as an arbitrary pattern, character, or design.
The print layer 23 is preferably formed on the surface of the second base film 21 using a solvent-based ink.
The printing layer 23 formed using the solvent-based ink is fixed on the surface of the base film in a state where it has soaked into the second base film 21. Therefore, the image is excellent in sharpness and fastness.

As the solvent-based ink, a conventionally known solvent-based ink mainly composed of a solvent, a pigment, a vehicle, and an auxiliary agent blended as necessary can be used.
In particular, as a vehicle, a vinyl resin such as vinyl chloride-vinyl acetate copolymer resin, an acrylic-vinyl acetate copolymer resin, or a solvent-based ink containing an acrylic resin is used for adhesion to the base film. It is preferable at the point which is excellent in. Two or more of the above vehicles may be used in combination.

Examples of the solvent include glycol ether solvents such as diethylene glycol diethyl ether, tetraethylene glycol dimethyl ether, tetraethylene glycol monobutyl ether, lactone solvents such as γ-butyrolactone, low boiling aromatic naphtha, propylene glycol monomethyl ether acetate, and the like. Can be mentioned.
Examples of the pigment include carbon black (black), copper phthalocyanine (cyan), dimethylquinacridone (magenta), pigment yellow (yellow), titanium oxide, aluminum oxide, zirconium oxide, nickel compound, and the like. Various other pigments are already known as the pigment, and are not limited to those described above.

  Specific examples of such solvent-based inks include, for example, SS21 ink, ES3 ink (both manufactured by Mimaki), Eco-Sol MAX (manufactured by Roland).

A method for forming the printing layer 23 is not particularly limited, and a conventionally known printing method such as direct gravure printing, offset printing, screen printing, flexographic printing, electrostatic printing, and inkjet printing can be used. Of these, inkjet printing is preferred. This is because it is easy to deal with multi-product and small-lot production.
Although the inkjet apparatus used by the said inkjet printing is not specifically limited, For example, CJV-30, TPC-1000 (both made by Mimaki), XC-540, SP-300 (both made by Rolland) etc. are mentioned.

The adhesive layer 22 is preferably a layer made of a hot melt adhesive (hot melt adhesive layer).
Examples of the hot melt adhesive include polyester hot melt adhesives, acrylic hot melt adhesives, rubber hot melt adhesives, and silicone hot melt adhesives.
Since the hot melt adhesive layer does not contain a solvent, it is suitable for performing decoration using a decorative film by vacuum forming or vacuum / pressure forming.

The thickness of the adhesive layer 22 is preferably 25 to 50 μm.
If the thickness of the adhesive layer 22 is less than 25 μm, it may not be possible to secure a sufficient adhesive force with the core material. On the other hand, when it exceeds 50 μm, cohesive failure is likely to occur in the adhesive layer, and it may be difficult to form the adhesive layer so that the surface thereof is smooth.

As shown in FIG. 2, a separator 24 is laminated on the side of the adhesive layer 22 opposite to the second base film 21 side. The separator is an arbitrary layer provided as necessary in the present invention.
It does not specifically limit as the separator 24, A conventionally well-known thing can be used, For example, resin films, such as PET film and polypropylene film surface-treated with the silicone resin, can be used suitably.

  Moreover, in the decorating film 20, surface treatments, such as embossing, may be given to the surface of the 2nd base film 21 or the printing layer 23 as needed.

The configuration of the decorative film is not limited to the configuration shown in FIG. 2. For example, a surface protective layer may be further laminated on the printed layer via an adhesive layer. .
In this case, in the produced decorative molded product, the surface of the decorative surface is protected by the surface protective layer.

The surface protective layer is, for example, a layer formed using a vinyl chloride resin composition or an acrylic resin composition, and is transparent.
The surface protective layer may be formed using a commercially available vinyl chloride resin film or acrylic resin film.

As a surface protective layer formed using the said vinyl chloride resin composition, the layer which consists of a vinyl chloride resin composition which mix | blended the plasticizer and the stabilizer with the vinyl chloride resin is mentioned, for example.
Here, the average degree of polymerization of the vinyl chloride resin is preferably 700 to 1500.
The plasticizer is preferably a plasticizer having an average molecular weight of 350 to 3000, such as diethylhexyl phthalate (DOP).
Furthermore, the blending amount of the plasticizer is preferably 5 to 30 parts by weight with respect to 100 parts by weight of the vinyl chloride resin.

Examples of the surface protective layer formed using the acrylic resin composition include acrylite, acrylene (both manufactured by Mitsubishi Rayon Co., Ltd.), sand durene (manufactured by Kaneka Corp.), and the like.
The surface protective layer is preferably a layer formed using an acrylic resin composition from the viewpoint of excellent transparency.
The thickness of the surface protective layer is usually about 40 to 200 μm.

The adhesive layer for laminating the surface protective layer on the printed layer is a layer formed using, for example, an acrylic adhesive, a rubber adhesive, or a polyester adhesive, and is transparent.
Examples of the acrylic adhesive include those containing a C1 / C4 acrylic ester copolymer, a C4 acrylic ester copolymer, a C8 acrylic ester copolymer, etc. as the composition of the acrylic component, What is necessary is just to select suitably the combination of a composition of an acrylic component, and a hardening | curing agent according to uses, such as adhesiveness and heat resistance.
Specific examples of the acrylic adhesive include SK Dyne 1506 (manufactured by Soken Chemical Co., Ltd.).

  When the decorative film includes a surface protective layer, the surface protective layer does not necessarily have to be laminated via an adhesive layer, and is directly laminated on the second base film on which the printed layer is formed. Also good.

In the decorative molded laminate 1, the adhesive force of the protective film 10 to the decorative film 20 is preferably 0.5 to 20 (N / 25 mm).
When the adhesive strength is less than 0.5 N / 25 mm, the decorative film cannot be held in the series of steps for attaching the decorative molding laminate to the core material, and the protective film is peeled off from the decorative film. Sometimes. In particular, when the behavior of the decorative film and the protective film with respect to heat is different, due to the low adhesive force, floating tends to occur between the decorative film and the protective film at the time of heating, and both are easily peeled off.
On the other hand, when the adhesive strength exceeds 20 N / 25 mm, when the protective film is peeled off from the decorative film after the lamination of the decorative molding laminate is completed, it cannot be smoothly peeled off. In addition, wrinkles, peeling marks, adhesive residue, and the like may occur on the surface of the decorative film after the protective film is peeled off.
In the present invention, the wrinkle refers to what occurred in the decorative film when the laminate for decorative molding is attached to the core material, and the peeling trace refers to the protective film when the protective film is peeled off. What is generated on the surface of the decorative film by being pulled by the

The adhesive force of the protective film to the decorative film is measured by a method based on JIS Z 0237.
Here, what laminated | stacked the decoration film on the aluminum plate is used as a test board (adhered body). At this time, the width of the protective film is 25 mm, the peeling distance is 50 mm, and the peeling speed is 300 mm / min.

Next, a method for producing the decorative molding laminate will be described.
For example, the decorative laminate may be prepared by separately preparing a decorative film and a protective film and then bonding them together.
(1) Production of a decorative film.
(1-1) First, a second vinyl chloride resin composition is prepared, and then the obtained second vinyl chloride resin composition is formed to produce a second substrate film.
The second vinyl chloride resin composition can be prepared by melt-kneading a predetermined amount of each compounding component using a continuous kneader, a Banbury mixer, a kneader, an extruder, or the like.
The film formation can be performed by calendar molding, extrusion molding, injection molding, or the like.
The film formation is preferably performed by calendering. Calendar molding makes it easy to make the thickness of the base film uniform, can be formed regardless of the composition of the vinyl chloride resin composition, and can be used to form bases of various sizes such as larger sizes. This is because it is suitable and it is easy to handle small lots.
Examples of the calendar format used for the calendar molding include an inverted L shape, a Z shape, an upright two shape, an L shape, and an inclined three shape.
Moreover, the roll temperature at the time of calendering may be appropriately selected according to the composition of the second vinyl chloride resin composition, but is usually 140 to 190 ° C, and preferably 160 to 180 ° C.

(1-2) Next, an adhesive layer is formed on one side of the second base film.
In the case where the adhesive layer is made of a hot melt adhesive, the adhesive layer may be formed by a conventionally known method, which is formed by directly applying the second base film using a hot melt applicator or the like. Alternatively, it may be formed by once applying to a separately prepared support and then transferring.
At this time, if a separator is used as the support, the separator can be laminated simultaneously with the formation of the hot melt adhesive layer.

(1-3) Next, a printing layer is formed on the surface opposite to the side on which the adhesive layer of the second base film is formed.
The print layer is formed using solvent-based ink or the like as described above.
The method for forming the print layer is as described above.
The order of forming the adhesive layer and forming the print layer may be reversed.

(1-4) Then, a surface protective layer is laminated | stacked on the said printing layer as needed.
For example, after producing a transparent film to be a surface protective layer by calendering or the like, an adhesive is applied to one side of this transparent film, and this is attached to the surface on which the printed layer of the second base film is formed, and bonded. A surface protective layer is laminated via the agent layer.
For example, after producing the said transparent film, this transparent film may be directly affixed on the said printing layer by the heat laminating method, and a surface protective layer may be laminated | stacked.
Any of these methods can be suitably used when the design of the printed layer is a pattern or a solid print, but when the design is a logo or a photographic image, A method of laminating a surface protective layer via an adhesive layer is preferred. This is because, when laminating by the thermal laminating method, the second base film is stretched during the thermal laminating, and the printed layer design may be distorted.
A decorative film can be manufactured by passing through such a process.

(2) Preparation of a protective film.
(2-1) A first base film is produced.
The first base film can be produced by the same method as the production of the second base film. After the first vinyl chloride resin composition is prepared, it may be formed by calendering or the like. .

(2-2) Next, an adhesive layer is formed on one side of the first base film.
The pressure-sensitive adhesive layer is formed, for example, by previously forming a pressure-sensitive adhesive layer made of a solvent-type or emulsion-type pressure-sensitive adhesive on one side of the support, and bonding the first base film on the pressure-sensitive adhesive layer, It can carry out by what is called a transfer method which transfers an adhesive layer to the 1st substrate film.
A protective film can be manufactured through such a process.

(3) Production of decorative molded laminate The protective film produced through the above-described steps is pasted to the surface on which the printed layer (or surface protective layer) of the decorative film is formed using a conventionally known method. The laminate for decorative molding is used.
By undergoing such a process, the decorative molded laminate of the present invention can be produced.

  The laminate for decorative molding can be used for decorating a core material. In particular, the decorative molded laminate provided with the protective film of the present invention has a step of attaching a decorative film softened by heating using a hot plate provided with a vent to the surface of the core material. It can be suitably used in a method for producing a molded product.

Next, a method for producing a decorative molded product using the laminate for decorative molding will be described with reference to the drawings.
3 (a) and 3 (b), and FIGS. 4 (c) and 4 (d) are schematic diagrams for explaining a method for producing a decorative molded product using the decorative molding laminate of the present invention. is there.
In the method for producing a decorative molded article, the protective film is peeled after the decorative molding laminate of the present invention is attached to the surface of the core material by vacuum molding or vacuum / pressure forming.

The core material is not particularly limited as long as it is generally used for decorative molded products, and for example, a core material made of resin, metal, or ceramic can be used.
Further, the shape of the core material is not particularly limited.

  The material of the core material (resin core material) made of the above resin is not particularly limited. For example, polyethylene resin, polypropylene resin, polystyrene resin, polyethylene terephthalate resin, polyvinyl alcohol resin, vinyl chloride resin, polyamide Resin, polyacetal resin, polycarbonate resin, acrylonitrile / butadiene / styrene (ABS) resin, ionomer resin, and resin compositions obtained by adding various additives such as inorganic fibers to these resins.

  It does not specifically limit as a material of the said metal core material (metal core material), For example, iron, aluminum, copper, SUS, etc. are mentioned.

A plurality of vent holes 43 are provided. The vent hole 43 is connected to a vacuum tank 54 equipped with a vacuum pump, and is configured to drive the vacuum pump during molding to depressurize the accommodation space R. The decorative molding laminate 1 can be fixed to the upper end (frame upper edge portion 40a) of the peripheral wall portion 41 of the lower frame 40 so as to close the opening of the accommodation space R.
Further, the lower frame 40 is installed on a slidable mount 52 and can be moved forward and backward with respect to the molding position on the lower side of the hot plate 30.

  The hot plate 30 has a flat plate shape in which the heating surface 30a has a smooth flat surface, and is larger than the lower frame 40 in a plan view. The hot plate 30 is provided so as to be movable in the vertical direction so as to approach or separate from the lower frame 40 disposed at the lower molding position, and in the state of being moved downward, It becomes the structure arrange | positioned closely to the frame upper edge part 40a.

  The heating plate 30 is provided with a plurality of heaters 32 on the upper surface side and a plurality of ventilation holes 31 (31a, 31b...) That open to the heating surface 30a. These vent holes 31 are connected to a vacuum tank 54 provided with a vacuum pump for sucking the heating surface 30a side, and are connected to a pressurized tank 53 for storing compressed air by a compressor as necessary.

  First, the outer periphery of the decorative molding laminate 1 is fixed to the frame upper edge 40a of the lower frame 40 by a fixing means (not shown) and is maintained in a horizontal state (see FIG. 3A). At this time, the laminate 1 for decorative molding is disposed such that the protect film 10 is positioned on the upper side and the decorative film 20 is positioned on the lower side, and the lower surface of the decorative molded laminate and the core material 51 are arranged. There is a sealed gap between them.

  Therefore, the molding apparatus 100 is configured to hold the lower frame 40 and the hot plate 30 in close contact with the decorative molded laminate 1 sandwiched between the adsorption / heating operation by the hot plate 30 and the decorative molded laminate 1. In parallel with the decompression operation in the housing space R on the side, the adsorption operation by the hot plate 30 is stopped after a predetermined time from the start of these operations, and the atmosphere between the hot plate 30 and the decorative laminate 1 is opened to the atmosphere. It is comprised so that the shaping | molding operation | movement which carries out or pressurizes can be performed.

Next, the decorative molding method of the core material 51 by the decorative molding laminate 1 using the molding apparatus 100 will be described in the order of steps.
