本発明は、バール顔料を含有した光沢のある合成樹脂成
形物に、所望の模様を形成する新規な方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel method for forming a desired pattern on a glossy synthetic resin molded article containing a Burl pigment.
従来より、バール模様を有する種々の合成樹脂成形品が
市場に出回つているが、この模様を形成する方法として
は、以下の2通りの方法が知られている。Conventionally, various synthetic resin molded products having a burl pattern have been on the market, and the following two methods are known as methods for forming this pattern.
一つは、バール顔料が同一方向に配列、含有された種々

脂を該バール顔料含有樹脂と同時に押し出してバール光
沢を有する流れ模様を形成する方法である。One is to cut synthetic resin plates with Burl luster in various tones containing Burl pigments arranged and contained in the same direction, and then assemble and laminate the same-colored or different-colored cut pieces into a desired pattern.
One method is to squeeze and heat-fuse to form a burl pattern, and the other is to use two or more extruders to create a transparent or semi-transparent synthetic resin containing kneaded burl pigment. This is a method in which a resin is extruded simultaneously with the Burl pigment-containing resin to form a flowing pattern with Burl luster.

要とせず、図柄模様、流れ模様のいずれでも再現性よく
且つ高性能で形成し得るものである。However, in the former method, the processes such as cutting the synthetic resin board, assembling the cut pieces, and laminating them are cumbersome, and especially when forming fine patterns, the above process requires a lot of effort, resulting in inefficiency. Moreover, there was a problem that it was difficult to obtain a flowing pattern with this method. On the other hand, in the latter method,
Even if it is possible to obtain a flowing pattern, it is impossible to obtain a design pattern, and since the resin containing Burl pigment that makes up the flowing pattern is wrapped inside, the outer resin cannot be made of transparent or There was a constraint that the internal flow pattern could not be seen unless a translucent material was used. The present invention has been made in view of the above-mentioned problems, and utilizes the characteristics of Burr pigments, that is, their orientation, to form a synthetic resin molded body containing Burr pigments and a thin synthetic resin surface layer. By forming irregularities on the surface of the integrated synthetic resin molding, the orientation of the Burl pigment is changed, and then by cutting and removing at least the convex portions of the unevenness, parts with Burl gloss and areas without Burl gloss can be differentiated. This is an epoch-making method that attempts to form a unique deep burl pattern made of Any of these can be formed with good reproducibility and high performance.
以下、図面を参照しながら本発明模様形成方法を詳細に
説明する。Hereinafter, the pattern forming method of the present invention will be explained in detail with reference to the drawings.

As shown in the figure, the method of the present invention includes a molding step A for obtaining a synthetic resin molded article in which a synthetic resin molded article body containing a Burl pigment and a thin synthetic resin surface layer are integrated, and forming unevenness on the surface of the molded article. This process consists of an embossing process B, in which the embossed surface is formed, and a process C, in which at least the convex portions of the irregularities are cut and removed.

の板状の樹脂成形物4を得る。That is, according to the pattern forming method of the present invention, first, in the molding step A, the molten synthetic resin mixture containing the pearl pigment 1 is once stored in the manifold 31 in the extrusion die 3, and then A laminar flow is generated in the slit 32 to arrange the pearl pigments 1 in multiple layers in the extrusion direction, and the surface layer transparent molten synthetic resin 20 is merged with the resins 2 and 20.
By extruding the synthetic resin molded body 4a to the outside,
The thickness of the integrated surface layer 4b is 2 to 10 m1! A plate-shaped resin molded product 4 of approximately L size is obtained.

の熱可塑性合成樹脂が使用される。FIG. 2 is a schematic enlarged view of the plate-shaped molded product obtained in this molding process A. Naturally, the pearl pigments 1 inside are arranged in multiple layers in the same direction (extrusion direction) as shown in the figure. Contained in a state of Pearl pigment 1 is generally a fine thin foil-like material on the order of microns, and it produces a beautiful deep pearl luster only when it is arranged in multiple layers in the same direction, and the arrangement is disordered (
(no orientation) and almost no pearlescent luster.
Here, the synthetic resin 2 constituting the synthetic resin molded body 4a is
There are no particular restrictions on the resin as long as it can be uniformly kneaded without destroying the pearl pigment 1, but preferably a polyvinyl chloride resin that can be easily softened by heating and can be easily extruded or embossed. , thermoplastic synthetic resins such as polyethylene resin, polycarbonate resin, acrylic resin, acetate resin, etc. are used.

の模様状に形成する。In addition, the synthetic resin 20 constituting the surface layer 4b is not particularly limited as long as it adheres strongly to the synthetic resin 2, is easily softened by heating, and can be easily subjected to extrusion molding or embossing. As will be described later, the surface layer 4b may also contain a Burl pigment, so the above-mentioned thermoplastic synthetic resin is preferably employed. Furthermore, as pearl pigments, all conventionally known pearl pigments can be used, and the blending amount is usually 0 parts of pearl pigments per 100 parts (parts by weight, hereinafter the same) of resin.
.. It is about 5 to 2 parts. According to the method of the present invention, next, in the embossing step B, unevenness is formed on the surface of the synthetic resin molded article in a desired pattern with a thickness equal to or deeper than the thickness of the surface layer 4b.

なつて平滑面となるまで切削除去される。In the case of the illustrated example, before the extruded plate-shaped product 4 is cooled and solidified, an etching roll 5 is used to form irregularities, but the embossing method is not limited to this embossing method. Any known embossing means can be used, such as heating and softening the immediately cooled and solidified resin molding 4 to a vorticity that allows embossing, and then compressing the desired uneven pattern with a press mold provided with the same. FIG. 3 is a schematic enlarged view of the pattern of the plate-shaped resin molded article 4 with unevenness obtained in this embossing step B, and the burl pigment 1 in the surface layer portion where the unevenness is formed has an uneven shape as shown in the figure. However, this plate-shaped resin molding still appears to have a nearly uniform pearlescent luster. The depth of the unevenness is desirably at least 0.5 nm or more so that the pearl pigments are sufficiently oriented and arranged and is greater than the thickness of the surface layer 4b. The upper limit of the depth is free, but if the unevenness is too large, the next cutting process C will be troublesome, so the thickness should be 2 to 10 m as described above.
0.7 to 2.0 in the case of a plate-shaped resin molded product of about 1
It is preferable that the irregularities have a depth of about 11 mm. In the next cutting step C, the resin molded article 1 with the unevenness is removed by a cutting machine 6 such as a shaper or a planer until the unevenness disappears and a smooth surface is obtained.

したまま着色し、有名透明層とすることが出来る。FIG. 4 is a schematic enlarged view of a resin molded article 4'' with a pearl pattern obtained in this cutting process C, and as shown in the figure, the pearl pigment 1 in the surface layer portions 41, 41 with convex portions stands up diagonally. The pearl pigments 1 in the surface layer portions 42, 42, 42 with the recesses are arranged in multiple layers in the same direction, almost parallel to the smooth cut surface. The portions 42, 42 overlap with the transparent surface layer 4b, creating a surface area that emits a unique deep and strong pearlescent luster as if you were looking through the water surface, while the surface layer portion 41, which has convex portions, 41, the surface layer 4b has been removed, resulting in a low chroma exposed surface area with almost no pearlescent luster,
The contrast between these areas on both sides creates a unique and beautiful pearl pattern even though it is a single color. The resin molded product 4 on which such a pearl pattern is formed will not undergo disappearance of the pearl pattern, breakage, large distortion, etc. even during subsequent bending, polishing, and other post-processes. For example, it can be used as a suitable material for eyeglass frames and other decorative articles. The above is an example in which the surface layer 4b is formed of the transparent synthetic resin 20, but the surface layer 4b is colored with an appropriate colorant (pigment or dye) while maintaining translucency, and is used as a well-known transparent layer. You can.

特の模様を形成できるものである。In this way, the surface layer portions 42, 42, 42 exhibit a unique deep glow due to the combination of the color mixing effect of the molded product body 4a and the surface layer 4b and the pearlescent luster, and also have almost the pearlescent luster. The contrast between the exposed molded body 4a and the different colored surface layer parts 41, 41 creates a two-colored pearl pattern that is different from the above. In addition, if the surface layer 4b contains the pearl pigment 1 to an extent that does not impede its translucency and is oriented in the same direction, the synergistic effect with the pearl pattern in the molded body 4a will further enhance the pearl pigment 1. You also get the benefit of increased depth. Furthermore, if the surface layer 4b is an opaque layer that is different in color from the molded product main body 4a using a combination of a coloring agent and a pearlescent pigment, the remaining surface area of the different-colored surface layer with pearly luster and the exposed surface region of the molded product main body without pearly luster. It is also possible to form a two-color pearl pattern consisting of , and these are appropriately selected according to the motif. As can be understood from the above explanation, the pattern forming method of the present invention does not require any of the troublesome and inefficient steps such as cutting, assembly, and lamination in the conventional method described above, and embossing step B and cutting step By C,
It is now possible to form patterns with high reproducibility and high efficiency, whether it is a design pattern or a flow pattern, and the resulting pearl pattern has a bright part with strong pearl luster and a low chroma part with poor pearl luster. Moreover, since the synthetic resin molded product according to the present invention has a surface layer, when the surface layer is made transparent, the pearl pattern inside has a unique depth that makes it look as if you are looking at the underwater pattern through the water surface. It is possible to form a unique pattern in which the depth, the brightness portion, and the low chroma portion are combined.

。The temperature condition at this time is 150 to 2
The temperature was 10°C and 220°C in the mold part. The temperature of the extruded plate-like material was adjusted to 80°C and the surface was coated with a coating of 1.0 to 1.
.. The material was guided to an etching roll with a flow pattern engraved at a depth of 81 m, and an uneven flow pattern with a difference in unevenness of 0.7 to 1.5 mm was formed on the surface of the plate. The product with this uneven flow pattern had a red pearly luster throughout through the transparent resin layer on the surface, was cooled while being moved on a conveyor, and was cut into pieces within 1 m in length using a cutting machine. . Furthermore, the gap between the etching roll and the pressing support roll is 6.7.
I adjusted it slightly. Next, when the irregularities on the surface of the plate were ground down until it was completely smooth with a planer, a beautiful flow consisting of a bright part with a deep pearly luster and a part with a poor pearly luster was created through the transparent resin layer. A pattern has emerged.
