くく高価でもあることから、天然産の花崗岩には到底か
なわないまでも、セメントに種石として花崗岩の細粉を
混入硬化させたものを研磨した人造石も出回っている。(Conventional technology) Natural stones such as granite have a glossy appearance when polished, and have unique surface patterns and a sense of weight, giving them a luxurious feel, and have been used for architecture and tombstones since ancient times. Widely used. And since this granite is also difficult to obtain and expensive these days, there are also artificial stones made by mixing cement with fine granite powder as a seed stone and hardening it, and polishing it, although it cannot compete with natural granite. It's on the market.
上記花崗岩や人造石はいずれも比重が大きく重いので、
熟練工による研削や研磨によって所定形状の物品に加工
され、主に装飾用石材として利用されているが、その物
性上、複雑で細かい形状をした物品への加工は難しく、
その用途が限られていた。Both the granite and artificial stone mentioned above have a large specific gravity and are heavy, so
It is processed into articles of a specified shape by grinding and polishing by skilled workers, and is mainly used as decorative stone. However, due to its physical properties, it is difficult to process it into articles with complex and detailed shapes.
Its use was limited.
そこで、−見自然石の感じを与え、しかも軽量であって

の開発が望まれていたが、現在までのところ、つぎの（
ａ）〜（Ｃ）に列挙するような種々の新規材料が開発さ
れている。Therefore, there has been a desire to develop a new natural stone-like material that gives the feel of natural stone, is lightweight, and can be used in a wide range of applications.
Various new materials as listed in a) to (C) have been developed.
（ａ）自然石の表面柄模様を紙表面に印刷し、その表面

Place an appropriate amount of natural stone powder mixed and kneaded into the
A natural stone pattern plastic product obtained by pressing the product with a male mold at a predetermined pressure or by injection molding into the mold.
（発明が解決しようとする課題）
しかしながら、上記の（ａ）の自然石柄印刷板材は従来
の壁紙の柄印刷に代えてを単に自然石の表面柄模様に印
刷としたに過ぎないから、平面的であって、自然石特有
の質感や重量感にはほど遠く、プラスチック成形のよう
にいろいろな形状の製品を成形できなかった。(Problem to be Solved by the Invention) However, the natural stone pattern printed board material in (a) above simply prints the pattern on the surface of the natural stone instead of printing the pattern on the conventional wallpaper, so it cannot be used on a flat surface. However, it was far from the texture and weight unique to natural stone, and it was not possible to mold products into various shapes like plastic molding.
また、（ｂ）の自然石柄プラスチック製品はベースが合
成樹脂であるので、金型によっているんな形状に成形可

に石粉による傷が付きやすく、金型を台無しにすること
もあった。In addition, since the natural stone pattern plastic product (b) has a synthetic resin base, it can be molded into any shape with a mold, but it is difficult to spread stone powder evenly on its surface. If the density varies and the resin is dispersed, the bare surface of the resin may be visible.Furthermore, during pressing, the inside of the mold was easily scratched by stone dust, which could ruin the mold.
さらに（Ｃ）の自然石柄プラスチック製品もベースが合
成樹脂であるので、（ｂ）のものと同様、いろんな形状

動性が悪くなって成形性に悪くなるという問題があった
。Furthermore, since the natural stone pattern plastic product (C) has a synthetic resin base, it can be molded into various shapes like the one in (b), but it is still susceptible to scratches caused by stone powder inside the mold during pressing. In addition, if the amount of stone powder added to the synthetic resin is too small, the weight and texture of natural stone will be poor, and on the other hand, if the amount of stone powder added to the synthetic resin is too large, the fluidity will deteriorate and the moldability will deteriorate. The problem was that it was getting worse.

もはかられることになる。(Function) Therefore, if the natural stone pattern plastic molding material according to the invention of claim 1 is press-molded in a predetermined mold, since it is a bulk semisolid in the B state, it will immediately change to the insoluble and infusible state in the C state. In addition, mica is heat resistant and resistant to compression, and is not altered or destroyed by press molding, so the mica shape is maintained as it is in the molded product, and aluminum hydroxide is compounded. However, the thermosetting resin does not become cloudy, and the mica appears irregularly and transparently on the surface of the molded product as a mineral pattern peculiar to natural stone, giving a feeling very similar to a natural stone pattern. In the invention of claim 2, when unsaturated polyester resin or acrylic resin is used as the thermosetting resin, since these resins have extremely good transparency, the pattern of the natural stone-like pattern made of mica becomes even clearer. appears on the surface of the molded product. Furthermore, when mica is colored as in the invention of claim 3, the colored state of the mica is directly reflected on the surface of the molded product, so a wide variety of patterns can be created. become. Furthermore, when the reinforcing material is blended into the thermosetting resin as in the fourth aspect of the invention, the resulting molded product becomes a reinforced plastic, so that the strength of the molded product can be improved.
（実施例） つぎに、本発明の実施例について説明する。(Example) Next, examples of the present invention will be described.

影響がでる傾向があり、望ましくは３０重量％前後が好
適する。The basic composition of the raw materials used for the natural stone pattern plastic molding material according to the present invention is (a) mica (8 to 20 weight%), (b) aluminum hydroxide (30 to 60 weight%), and (C
) Thermosetting resin (20-62% by weight). By the way, if the mica content is less than 8% by weight, a pattern that closely resembles the natural stone pattern, which is unique to mica, will not appear on the surface of the molded product, and if it is more than 20% by weight, the pattern will be more than natural stone pattern. The mineral pattern of mica appears on the surface, giving an unnatural feel, and the surface condition of the molded product tends to become rough. Therefore, the content is desirably about 12% by weight. Also,
If aluminum hydroxide is less than 30% by weight, the transparency of the molded product tends to decrease and the appearance of the mica mineral pattern on the surface of the molded product tends to be hidden, which is undesirable. Since moldability tends to deteriorate, the content is preferably around 50% by weight. Furthermore, if the thermosetting resin is less than 20% by weight, moldability will deteriorate, and if it is more than 62% by weight, it will inevitably affect the blending amount of mica and aluminum hydroxide, resulting in insufficient addition of mica and hydration. There is a tendency for the addition of aluminum to be insufficient, resulting in negative effects caused by the addition of aluminum, and the preferable amount is approximately 30% by weight.

料が得られることになる。The total amount of these basic formulations is 100% by weight, and each raw material can be freely combined within the formulation range, and natural stone patterns with slightly different surface pattern patterns or physical properties can be created depending on the mixing ratio. A plastic molding material will be obtained.

に設定する。Furthermore, by adding (d) reinforcing material (0 to 14% by weight) as an auxiliary raw material to the above basic formulation, it is possible to improve the strength of the physical properties of the natural stone pattern plastic molding material. If this reinforcing material is not added (0% by weight), the physical strength of the molded product will be extremely weak, and 14% by weight.
If it is more than that, the reinforcing material tends to stand out on the surface of the molded product and the surface texture is not finished smoothly, and the content is preferably around 12% by weight. In addition, when adding and blending this auxiliary raw material, it is set so that the total amount together with the basic blend will be 100% by weight.

ガラス繊維（たとえば、５ ａｎｎ長さ程度に裁断した
もの）であるが、この代わりにセラミック繊維やセラミ
ックウィスカー等地の補強材を用いて差し支えない。In addition, as the thermosetting resin in the above basic formulation, unsaturated polyester resin or acrylic resin is optimal, and as mica, in addition to naturally obtained mica, biotite, phlogopite, etc., synthetic mica may be used as is. but,
Depending on preference, these mica may be colored (can be colored in any color such as flesh color, red, gray, etc. by conventional coloring means) and used. Further, although the reinforcing material is generally glass fiber (for example, cut into about 5 ann long pieces), a reinforcing material such as ceramic fiber or ceramic whiskers may be used instead.

(% by weight), mica (12% by weight) and aluminum hydroxide (50% by weight) are blended, and preferably a reinforcing material (8% by weight of glass fiber cut into 5 mm pieces) is blended with this. By kneading, a bulk semi-solid in the B state of a so-called thermosetting resin is obtained.

寿命も一般のプラスチック成形に使用する金型と同様程
度に長期にわたって使用できることがわかった。After that, mica is moderately dispersed on the surface of the molded product taken out from the press mold, resulting in a plastic molded product with a natural stone pattern that closely reproduces the mineral dispersion state on the surface of natural stone.
The reinforcing effect of glass fiber is significant, making it suitable for applications where strength is required. Incidentally, under the above-mentioned compounding conditions, a molded article that does not contain only glass fiber has weak strength and is prone to cranking, so it is desired to be applied to applications where strength is not required. In addition, in any of the above cases, unlike conventional methods, stone powder is not mixed at all, so there is no damage to the inside of the mold, so the mold life is the same as that of molds used for general plastic molding. It was found that it can be used for a fairly long period of time.

にくくなるというメリットがある。By coating the surface of the obtained natural stone pattern plastic molded product with an ultraviolet curable resin, the transparency and gloss of the surface are significantly increased compared to the case where the ultraviolet curable resin is not coated. death,
Not only does it give the impression of a highly polished finish, but it also dramatically improves surface hardness, making it less likely to be scratched.

The pattern pattern unique to mica minerals is extremely similar to the surface pattern of natural stone, and in addition, thermosetting resins such as unsaturated polyester resin and acrylic resin serve as a matrix that acts as a binder. This makes it lightweight and extremely easy to handle.
