Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a decorative material that closely resembles natural stone and is suitable for interior materials and other decorative materials.

(Prior Art and Problems) Conventionally, in order to obtain a pattern similar to natural stone, a method has been used in which printed materials with natural stone patterns are attached to a substrate, but the surface is flat and a three-dimensional effect cannot be obtained.

In addition, decorative materials with cloud-shaped or stone-grained patterns were obtained using thermoplastic resin by heat-pressing molding chips of different sizes, shapes, and colors.

For example, in Japanese Patent Publication No. 38-4684, pigments are applied to the surface of a flowing pattern sheet, or a colored base sheet is pasted together, which is then shredded into small cubes, and after applying heat pressure to the shredded material, it is smoothed. By doing this, a marble patterned sheet is disclosed. However, such a synthetic resin sheet also has a monotonous pattern, and a complex pattern resembling natural stone cannot be obtained, and further improvements in design have been desired.

(Means for solving the problem) The present application is an invention that solves the above problem, and has a pattern piece of an iris-colored film with a side of 2 to 20 m in a polyvinyl chloride paste matrix material, or a pattern piece that is different from the matrix material. It is composed of a pattern block containing a mixture of chips, and the pattern block aggregate is integrally molded,
The gist of the decorative material is a decorative material characterized by having a continuous pattern formed by a combination of a large number of concave portions and convex portions. The present invention will be explained below based on the drawings.

Figure 1A and Figure 1A are pattern pieces used in the present invention.

In Figure 1A, the pattern piece 1 has a different color due to light interference, with the left side 2 being a gold color part and the right side 3 being a green part, for example, and when the viewing angle is changed, the pattern piece 1 becomes different as shown in the opening of Figure 1. The left side 2 and right side 3 change color, such as becoming opposite colors. This pattern piece l is made of pvc. It is obtained by providing one or two coating layers of polyester ethylene resin and cutting an iris-colored film, which can obtain iris colors by interference of light, into pieces of 2 to 20+ nm on each side.

FIG. 2 is a diagram of a lump that becomes a pattern in the present invention. 4 is a matrix material, which is a fluid composition of polyvinyl chloride (PVC) paste composition. A PVC paste composition is prepared by adding and kneading 20 to 50 parts of a plasticizer, a stabilizer, etc. to parts by weight of PVC IOO. The mixture obtained by kneading is a sticky paste. The matrix material obtained above may be colored as appropriate, but if the pattern pieces and synthetic resin chips are
It is once solidified by pre-gelling at 0 to 150°C and then hot-press molded in a subsequent process.

In the matrix material, the iris-colored pattern piece 1 alone or this pattern piece and a resin chip harder than the matrix material (
It contains a mixture of 6 (hereinafter referred to as chips). 1 is a pattern piece, and the transparent PVC paste matrix material and the pattern piece are mixed and coated and pregelled. At this time, the pattern piece should not be wrinkled or deformed.
C dispersed in the paste matrix material. The chip 6 also has a different color from the matrix material 4.

This definition of unusual also includes "being transparent or translucent."7' The pattern piece l and the chip 6 function as a pattern part included in the matrix material. The tip is 1-20m.
The chip may have a round shape or a square shape, and when the chip is made into a square shape, the periphery of the chip is coated with a transparent resin 7,
When these are packed close-packed into a matrix material and heated and pressurized in a subsequent process, the chips closely resemble natural stone's cleavages, joints, crystal structures, silk cracks caused by natural weathering, and other cracks; The present invention provides a desirable design with a sense of weight that closely resembles the appearance of natural stone. The matrix material 1, chips and pattern pieces are mixed together using a device such as a Henschel mixer, a ribbon blender, a mortar mixer, or a planetary mixer, and then pre-gelled to obtain a pattern block 5 in which the chips are encapsulated in the matrix material.

The pattern block 5 thus obtained has an oval shape with a diameter of 8 to 80 mm, as shown in FIG.

FIG. 3 shows another embodiment of the pattern block, in which round or square chips 8, 9 with a diameter of 1 to 20 m are used as matrix material 10.
It is filled with high density. This pattern block 11 has a diameter of 8, for example, as shown in the combined pattern block 5 of FIG. 12. Note that the obtained pattern block 11 may be divided into pieces of appropriate thickness.

FIG. 4 is a diagram of the decorative material of the present invention in a mold state, in which an aggregate of patterned lumps 12 and 13 obtained by the above method is plate 1.
The decorative material of the present invention having a thickness of 5 to 50 mm is obtained by heating and pressing at 140 to 200° C. between 4 and 14' to form an integral mold. Although the patterned lumps 12 and 13 do not have much difference in composition content, they have a continuous pattern formed by matrix material and chiseling, and the supply amount of the corresponding patterned lumps is smaller than that of the heat-pressing molding. An island-in-the-sea structure is obtained by the ratio.

The pattern portion 17 includes a pattern piece l5 and a chip l6, and the pattern portion 18 includes chips 19 and 20.

A decorative material 23 obtained by slicing or smoothing the surface of the obtained patterned material is a decorative material 23 obtained by slicing or smoothing the surface of the patterned material 17, 18. This may be surface-finished and used as is, or may be sliced and laminated with a base material.

FIG. 5 is a plan view of the decorative material of the present invention.

The pattern portions 17 and 18 are molded by heating and pressurizing the pattern lumps that have been solidified by pre-gelling or the like and integrating them. The pattern portions 17 and 18 are a combination of an island pattern consisting of a large number of sets of concave portions and convex portions and a sea pattern consisting of the pattern material 17, and these pattern materials have surfaces of the island pattern formed in the shape of protrusions 21 and depressions. It features a continuous pattern in which the parts 22 are intricately intertwined, and these dangling effects show an excellent design that was not found in conventional interior materials.

In the decorative material 23 of the present invention, the patterned portion 18 has a chip 1.
9 and 20, the pattern part 17 has a pattern piece l5 and a chip 16.
The chips are integrated under heat and pressure while being encapsulated, and the chips are interposed in the pattern material at a relatively high density.

In the present invention, the pattern piece 15 is made of pvc. An iris color film with a side of 2 to 20 mm that can obtain iris colors by light interference.
The color seen by a pedestrian on the decorative material when seeing the pattern piece (5) is different from the color seen when the same pattern piece is seen from another position.

As you walk, the color of the pattern pieces changes, so you always get a beautiful pattern with a rainbow of colors.

Furthermore, by coating the chips with the transparent resin, the outline of each chip can be clearly defined, resulting in a granite-like pattern with cleavage, natural cracks, or joints.

Of course, other shapes of chips or addition methods can provide different designs.

Note that the matrix materials in the pattern blocks 17 and 21 may of course be of different colors, but may also be of the same color.

According to the present invention, high design properties such as cloud patterns, granite patterns, marble patterns, and other natural stone patterns can be obtained depending on various embodiments.

(Function) By heating and pressurizing the aggregate of the pattern blocks once solidified to form a single piece, a combination of a large number of complexly deformed concave portions and convex portions, that is, planar protrusions and A highly decorative pattern with intricate recesses can be obtained.

The pattern pieces are mixed into the paste, and the film pieces are dispersed in the matrix without wrinkling or deformation.

Iris-colored film changes color depending on the viewing angle, so
Each pattern piece changes color as it walks, creating a multicolored effect.

Example 1 A PvC sheet with a thickness of 3 mm was pulverized with a cutter mill, and
~16 mesh beige chip A was produced. This chip was coated with transparent PVC powder. Next, a polyester film was coated with an acrylic resin, and the iridescent film coated with a polyurethane resin was cut into 3 m square pieces to obtain a pattern B of the present invention.

A white matrix material consisting of PvC paste group Kaimono C1 with the following distribution is added in the ratio of A:B:C = 47:3:50, heated while stirring to pre-gel the above matrix material at 120 ° C. Tufted pattern lump C
I got 2. CI PvC paste resin 100 parts by weight plasticizer (D
OP) 30 N Stabilizer 2 Pigment 0.2 A patterned mass D consisting of red chips, brown chips and brown matrix material was obtained using the same formulation as above. Lump C2: Lump D was charged into a press at a ratio of 3:4. The decorative material of the present invention was obtained by gelling the matrix material that was pressure-molded at 160°C. When the surface of the obtained decorative material was finished polished, both lumps C2 and D had a complicated uneven shape, and the surface was intricately intricate with protrusions and depressions, with C2 having an island shape and D having a sea shape. In the decorative material of the present invention, the chips and pattern pieces in the pattern block are not deformed, and the surface is coated with transparent resin, so it closely resembles the joints or crystals of natural stone, and the decorative material itself We were able to obtain the style of natural stone.

Furthermore, since the color of the pattern pieces changes as the position of the eyes changes, unlike conventional metal vapor-deposited types, a highly decorative multicolored decorative material with constantly changing rainbow colors was obtained.

Example 2 A decorative material of the present invention was obtained in the same manner as in Example 1, except that the chips were removed from the pattern block A of Example 1 and only the pattern pieces were added to the matrix material.

When the obtained decorative material was used as a flooring material, the amount of color change observed as the iridescent pattern pieces were walked on increased significantly, further increasing the designability of the rainbow-colored flooring material.

(Effects of the Invention) According to the present invention, a stately decorative material that closely resembles natural stone can be obtained, and since the iris-colored film pattern pieces change color as the pedestrian's viewing position changes, the rainbow colors constantly change. Decorative materials with high design quality can be obtained. First cause Figure 2 Figure 3 Figure 1
