Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wooden sheet having a metallic luster layer with a three-dimensional effect.

Conventionally, a gold-foil laminated layer sheet is known, which is made by integrally pasting gold leaf on one side of synthetic wood (MV-).

However, due to the difference in thermal expansion coefficient between the synthetic resin V-) and the metal foil that make up the sheet, peeling is observed at the lateral interface, and bulges, voids, cracks, etc. occur. However, there is a disadvantage that moisture, warm dust, etc. can enter.

Therefore, the inventors of the present invention have completed the present invention after conducting intensive research on laminated l-sheets, particularly sheets formed with a metallic luster layer. C
: A metallic gloss layer is provided on the surface of the convex part of a synthetic IM resin sheet having irregularities, and a transparent synthetic resin layer is provided covering the surface of the V-).

The laminated sheet according to the present invention having the above-mentioned structure has a metallic luster layer provided only on the convex portion of the synthetic resin V-), so that thermal expansion between the synthetic resin plate and the metallic lustrous layer is limited. The q-form etc. based on the difference in rate are absorbed in the concave portion of the V-), and there is no peeling, blistering, or voiding of these constituent materials even at room temperature or at considerably high temperatures. It has the remarkable effect of not having any

In addition, a synthetic resin sheet having S number of l[4 pores can provide the above-mentioned advantages more effectively, and it can also be used when attached to an object. The excess of the adhesive used escapes from the pores, and the strength of the adhesive beam or paddle is improved compared to those with a normal smooth surface, and the adhesive strength is improved during application or when applied. Strain, tension, etc. that cause wrinkles later are absorbed,
As a result, it is possible to obtain an extremely good appearance, and if the ground color of the 11 surfaces to be pasted is any color, it can be seen through the pores, so that the convex streetcar can be seen. Aesthetic effects can be achieved through the right harmony with metallic luster.

Next, the Dan sheet according to the present invention will be explained in detail based on the attached drawings.

Figure 111 shows the product II of the present invention! /-) is a partially enlarged cross-sectional view showing the basic aspect of the
2 is a synthetic resin sheet having a convex shape 511), 2 is a metallic luster, and 3 is an optically transparent synthetic resin layer. Figure 2 shows another embodiment of the laminated sheet of the present invention. First, in the laminated layer V-) of the present invention, the synthetic resin *v-H11' that constitutes the base layer has a large number of convex portions 11 on its surface. It is essential that it is something that has something to do with it. There are no particular restrictions on the shape, size, dotted state, etc. of these convex portions, and these convex portions that have a purpose or purpose should be spaced apart enough that the convex portions do not stick together and cause stretching or wrinkles. For example, the shape may be prismatic such as a triangular prism, quadrangular prism, hexagonal prism, cylindrical shape such as a perfect circular cylinder or elliptical cylinder, or even an irregularly shaped column. For a) in Figure 1, the height may be on the order of a millimeter to a centimeter, and for b) in the same figure, the height may be on the order of 100μ thick to a millimeter. It may also be provided arbitrarily irregularly [FJl=.

The average thickness of this sheet (O in the figure) is approximately 0.0
fSl11 or more, but this is because if it is too thin, the difference between the convex portion and the concave portion will be small, making it impossible to satisfactorily achieve the object of the present invention. be.

Although the upper limit is not particularly specified, it is generally set to be less than or equal to IEII.

In addition, regarding the present invention, it is desirable to provide countless through pores in the cough synthetic resin *V-) for the purpose of imparting adhesive properties, anti-wrinkle properties, decorative properties, etc. as described above. There is no restriction on the shape, number, etc. of the pores; for example, there is no problem even if the pores are partially formed into a convex portion, or may be partially dense.

Furthermore, this i/-) is colorless transparent, colorless opaque, colored transparent, lrt! ! It may be either opaque or opaque, and this may be arbitrary depending on the purpose, etc., but especially when a colorless and transparent one is used, it will not only have a metallic luster, but also a partner in the application. A new color can be obtained by combining it with the original color tone of the surface to which it is attached.

Examples of materials constituting such a material include polyvinyl chloride, polyvinylidene chloride, polypropylene, polyvinyl acetate, polystyrene, polybutadiene, polymethyl methacrylate, copolymers thereof, and blends thereof. can be given. Among these, highly fluid 17N heath resins, such as polyvinyl chloride paste resins, are suitable for use as adhesives.

The back side of the plate with H, may be processed as needed, and by doing this, C when applied.
Second, even more reliable adhesion can be provided.

Next, as the metallic luster 1l12 provided on the convex portion 11 of the above-mentioned sea) 1.1', metal foil is used. ! ! Examples include glands, phlegm, etc., and these can be transferred, applied, and is.

This layer may be applied as a seed layer, etc., and this layer may have a colored gold luster with any color in addition to gold, silver, toning, etc.2 This gold luster layer is as described above. As a general rule, it is provided only on the convex portions 11 of the sheets 1, 1', but a small amount may be used on the concave portions.

This is because if they are provided over the entire surface, the disadvantages of the conventional method cannot be overcome, and the effect (stereoscopic effect) produced by placing them at one point will be reduced by half or not at all.

The thickness of the metallic luster-2 is sufficient as long as it can impart metallic luster to the sheet obtained from this, and specifically, it is in the range of millimicron order to millimeter order.

More transparent composition! 1 scoop of 1113 protects the metallic luster of the nuclide (&-), and also has a strong
! It is provided for the purpose of improving abrasion resistance and scratch resistance, giving an optical three-dimensional effect to 1 ml of gloss, and further preventing contamination or facilitating removal when contamination occurs.

Although it is essential that the resin layer 8 be optically transparent for the reasons described in E, it is not necessarily required to be colorless and transparent, and may be colored and transparent, and even semitransparent. It may be.

The thickness of this resin layer 3 is approximately 0.2 to 1.0 m. If it is less than F, it will be too thin and not only will it not be possible to achieve the purpose of protecting the metallic luster layer described above, but also the optical C will be inferior in three-dimensional effect. On the other hand, if the axis rotation is more than the above-mentioned axis, wrinkles are likely to occur in the obtained rate, and optically, the three-dimensional effect will be impaired.

Examples of the material constituting the transparent synthetic resin-3 include polyvinyl chloride, urethane, ethylene-vinyl acetate co-electrolyte resin, etc., and the second resin in particular can form a resin with excellent abrasion resistance.

In addition, when using polyvinyl chloride with a vague blend of plasticizers, it becomes easier to adsorb dust and dirt due to migration or bleeding.
Furthermore, even if they are present, they can be easily removed by washing with water because of their excellent water solubility.

Although the drawing shows an example of an ll1iI sheet in which the concave part of the sheet 1 is a space, this space does not necessarily have to be formed, and the same or different material as the material constituting the transparent resin 1- may be used as a dense Il1iI sheet. : May be filled.

Next, the laminated layer 1/-) according to the present invention can be manufactured by various methods, and as shown in FIG. 1 Raw material supply process mA-) After creating a synthetic tree Hk * v-) 1 with unevenness on the surface by the casting method (# to provide through pores) (-(Tsting ball level B +, - cooling process No-), this V-) 1 and a transfer sheet 5 made of steamed aluminum or the like are placed on two drums in such a state that the curved surface of the transfer sheet faces the convex surface of the sheet 1. 6. At step 6', apply heat and pressure to transfer the aluminum smoke film of the transfer sheet to the convex portion of sheet 1 (; transfer, and then cover the transferred surface of the sheet obtained above as shown in FIG. 1o). The synthetic resin sheet 3 is placed horizontally and heated and pressurized to integrate and then cooled, or alternatively, the sheet 3 is heated and pressed so that no space is formed between the uneven sheet 1 and the transparent synthetic resin layer 3 as shown in the figure (@). Paste tree Il between them as shown
Examples include a method of filling la' and heating and pressurizing it to integrate it.

Among the above methods, the latter method has hl<h and the metallic luster color tone is better exhibited than the latter method, but this is because of the pressure during processing. IC=
This is presumed to be because the convex portions are not deformed and no cracks occur in the metallic luster layer.

The heating fi If and the pressurizing pressure ζ are slightly different depending on the constituent materials, but when polyvinyl chloride is used as the constituent material of the tomb material layer 1 and the transparent synthetic lubricant dove 3, the temperature is 80~200℃, pressure 0.5~
It would be best if it was set at 20:00/-.

Furthermore, in the above-mentioned integration, adhesives, adhesion agents, primers, etc. that have been conventionally used for adhering synthetic resin molded products may be used.

In the laminated layer according to the present invention, when it is desired to obtain a stronger fixation and integration of the metallic luster layer to the convex portion of the synthetic resin plate, the V-) and the transparent composite IIIt resin layer are combined. It is preferable to use the same material, and according to this method, the purpose can be achieved without using any compensating agents or the like.

The laminated V-t of the present invention can be used as is for wallpaper, ceiling paper, etc.
It can be used for a variety of purposes, including interior decoration such as flooring materials, home kitchen use such as tablecloths, etc.
For example, as shown in Figure 4, it is used by adhering it to a tile D made of conventionally known vinyl-asbestos, synthetic rubber, etc. (7 in the figure is tile paste, and 18 is tile color @). In this case, by selecting an arbitrary color tone as the tile color @g, it can maintain a suitable subphase with the metallic luster layer and provide a good color impression.

Next, examples and application examples of the present invention will be given.
