Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molded product having a gloss-matte pattern on its surface, which is molded using a shaped film.

[0002]

2. Description of the Related Art Conventionally, there have been the following techniques for forming fine irregularities on the surface of a molded article, that is, a matte surface called mat. First, a technique of forming fine irregularities on the surface of the transfer target by the transfer sheet will be described. The transfer sheet is a peelable base film,
A transfer layer comprising a release layer, a pattern layer, and an adhesive layer is formed, and this transfer technique brings a transfer sheet into contact with another transfer target, and an adhesive layer, a pattern layer, This is a technique of transferring the release layers in order. Therefore, the outermost surface of the transfer target becomes a release layer. Conventionally, in order to form a fine uneven pattern on the surface of such a transferred material, a preliminarily formed fine uneven pattern on the surface of a peelable substrate film is used, and a transfer layer is formed on this. Contact the transfer target,
It was transcribing. By this transfer, the transfer layer having a fine uneven pattern was transferred to the surface of the transferred material, and a mat-like surface was obtained.

Next, a conventional technique for forming fine irregularities on the surface of a molded body will be described. Molded items include, for example:
There is a decorative board, which is made by impregnating decorative base paper with a thermosetting resin, drying it, laminating it with core paper, overlay paper, and base material, and sandwiching it between the upper and lower heating plates with a metal mirror plate. It is heated and compressed. Examples of such decorative boards include melamine resin impregnated paper on about 4 pieces of phenol resin impregnated core paper, and overlay paper impregnated with melamine resin on the laminated paper and then heat-pressed the melamine decorative sheet. There is a board. Further, as another example, there is a DAP decorative board in which diallyl phthalate (DAP) resin-impregnated paper is sequentially stacked on a plate-shaped substrate and heated and pressed. When imparting fine irregularities to the surface of these decorative plates, between the mirror-finished plate with the fine irregularities formed on the surface, insert a patterning film and sandwich the plate-shaped substrate, and heat press molding And then
It was released from the mold to obtain a decorative plate having fine irregularities on the surface.

Further, as another example of the molded article, an ionizing radiation curable resin is applied to the surface of an object to be coated, and a patterning film is covered thereover and irradiated with ionizing radiation to cure the coating film. Then, the patterning film was peeled off to obtain an article to be coated having fine irregularities formed on the surface. Furthermore, as another example of the molded product, a shaped film is covered with a resin impregnated with an unsaturated polyester resin, the resin is cured, and the shaped film is peeled off to have fine irregularities on the surface. A molded body was obtained.

[0005]

However, the molded article produced by using the conventional patterning film having a fine uneven pattern formed on its surface has a matte surface, but it has been touched. The feeling was smooth and rough, and there was no slimy feeling. Moreover, there is no patterning film having a gloss-mat formed by mixing a fine uneven pattern and a flat surface on the surface, but only a patterning film having unevenness formed on the entire surface. .. The surface appearance of a product transferred or molded using such a shaped film was visually monotonous.

Therefore, the present invention provides a molded article having a gloss-mat having a high design effect in which a fine concavo-convex pattern and a flat surface are mixed on the surface, and further, a fine gloss-mat surface of the molded article is provided. The purpose is to make the uneven portion a moist, slimy, suede-like surface.

[0007]

In order to solve the above-mentioned problems, the molded article of the present invention has a surface formed by a gloss-mat adjusting film in which a fine uneven layer and a flat layer are mixed. To obtain a molded product. And the said fine uneven | corrugated layer shall make the average space | interval of unevenness | corrugation 20-50 micrometers, the average surface roughness Ra of unevenness | corrugation 0.7-2.0 micrometers, and the 60 degree gloss value of a surface shall be 2.0 or less. is there. By using the shape-imparting film in which the concavo-convex layer and the flat layer are mixed, the feel of the concavities and convexities of the matte portion of the gloss-matte pattern provided on the surface of the molded article is moist and has a slimy feel. A matte surface can be obtained. This feel is not slippery or shiny, yet unlike the gritty feel, it has a soft, suede-like smoothness, giving it some sort of high-class feel.

Incidentally, the average inclination angle of the irregularities means the height of the peaks of the irregularities h ₁ , h ₂ , h ₃ to, as shown in FIG.
When h _n , it means θ _a represented by the following equation (1).

[0009]

[Equation 1]

FIG. 1 shows a sectional view of the patterning film used in the present invention. The shape-imparting film used in the present invention is formed of a base film 1 and a surface layer in which a fine concavo-convex layer 2 and a flat layer 3 which are laminated on the base film 1 are mixed. The fine uneven layer 2 and the flat layer 3
The mixed surface layer is formed by partially printing resin on the fine uneven layer 2 formed on the entire surface of the base film 1. Furthermore, another means for forming a surface layer in which the fine uneven layer 2 and the flat layer 3 are mixed is to form a surface layer on the entire surface of the coating film of the liquid-repellent resin partially applied on the base film.
It is formed by applying a fine uneven layer forming resin composition.

A PET film is used as the material of the base film, and the base film used in the present invention is subjected to an easy-adhesion treatment in order to prevent the laminated fine uneven layer from being peeled off from the base film. ing. For such an easy-adhesion treatment, a corona discharge treatment, coating of various known primers, or a heat-sensitive adhesive layer is formed on the film surface.

The fine concavo-convex layer formed on the base film is formed using a resin composition composed of an inorganic filler and a binder resin. The binder resin is mainly acrylic polyol cross-linked with polyisocyanate, and the filler is calcium carbonate CaCO ₃ and silica gel SiO ₂ . The addition weight ratio of calcium carbonate and silica gel is 20:10 to 29: 1, and the particle size of the main filler calcium carbonate is 2 to 5 μm, preferably 3 μm.
And The average particle size of silica gel is about 3 times the particle size of calcium carbonate. The silica gel acts to adjust the surface roughness of the shaped film, and when only calcium carbonate is used without adding silica gel, the obtained surface becomes close to flat, and The surface cannot be obtained. In addition, silica gel also functions to prevent the precipitation of calcium carbonate.

Examples of the material for the base film of the shaped film used in the present invention include polyester resins such as polyethylene terephthalate (PET), polybutylene terephthalate, polyethylene terephthalate-isophthalate copolymer, polyethylene, polypropylene, Polyolefin resins such as polymethylpentene, polyvinyl fluoride, polyvinylidene fluoride, polytetrafluoroethylene, ethylene-4 fluoroethylene copolymers, and other polyfluorinated ethylene resins, nylon 6, nylon 66 and other polyamides, Polyvinyl chloride, vinyl chloride-acetic acid copolymer, ethylene-vinyl acetate copolymer, ethylene vinyl alcohol copolymer, polyvinyl alcohol, vinylon,
Vinyl copolymers such as cellulose triacetate, cellophane,
Cellulose resin such as, polymethacrylic acid ethyl, acrylic resin such as polybutyl acrylate, polystyrene, polycarbonate, polyarylate, polyimide,
Synthetic resin such as, or fine paper, thin paper, glassine paper, sulfuric acid paper, and the like are used.

A slit reverse coating is used as a method for applying a fine uneven layer to the base film. The reason for adopting this coating method is that the filler particles in the resin composition forming the concavo-convex layer flow like a circle when using a normal coating method such as gravure coating,
This is because streaks are formed on the patterning film. Therefore, in the present invention, in order to prevent such streaks, the slit reverse coating method shown in FIG. 3, which allows the coating film to have a certain thickness, is applied as a coating method. FIG. 3 shows an outline of the slit reverse coat. The resin composition discharged from the nozzle coating device is the sheet-like material 4 running on the backup roll.
The coating film thickness is regulated by the squeeze roll 2 and then the coating is performed.

Further, the embossing film used in the present invention is one in which a releasing agent is contained in the uneven layer on the surface.
As the release agent, silicone, fluororesin, various waxes, etc. are used. In the present invention, the transfer film is easily transferred to the transfer target by using the pattern-forming film as the base film of the transfer sheet and incorporating the release agent into the release layer in the base film. The release agent must be designed so as not to bleed too much on the surface in consideration of compatibility with the binder. If there is a large amount of bleeding on the surface, unevenness will occur in the uneven layer of the patterning film.

In order to eliminate such unevenness, it is important to have a good compatibility with the binder resin for forming the uneven layer. For example, when acrylic polyol is used as the binder, an amino-modified silicone oil having good compatibility with it is used. Further, if the amount of the release agent added is too small, the peeling will be heavy, and if it is too large, the adhesion between the uneven layer forming resin and the base film will be reduced, so that 0 to 8% by weight,
It is preferably 0.1 to 5% by weight.

Next, an example will be described in which the above-mentioned surface is surface-molded by using the gloss-mat matting film.
This is to form a transfer layer on the shape-imparting film, bring the shape-imparting film into contact with the transferred material, transfer the transfer layer to the transferred material, and a molded article having a gloss-matte pattern on the surface. To do. Since the matte part of the gloss-matte pattern of this molded product has fine irregularities, it feels soft and slimy to the touch, and is soft and smooth like suede. To get the body surface.

Further, according to the present invention, the shape-imparting film is inserted between the molded product formed by pressing between the heating pressure plates and the pressure plate to mold, whereby fine uneven portions and flat portions are formed on the surface. A press-molded product having a mixed gloss-matte surface is obtained. Examples of such a molded body include a melamine decorative board and a DAP decorative board.
In order to produce a melamine decorative board having a gloss-matte surface, about 4 pieces of phenol resin-impregnated core paper are laminated with a melamine resin-impregnated sheet, and an overlay paper impregnated with a melamine resin is further laminated thereon to form two sheets. It is sandwiched between mirror-finished metal plates, and the above-mentioned shape-imparting film having a gloss-matte pattern formed on the surface is inserted into the mirror-finished metal plate, for example, 100 kg / c.
