ることが広く行われているが、かかる従来の人造大理石
は、柄模様が単調で実物感に乏しく、その用途は限られ
たものとなっていた。(Prior art and problems to be solved by the invention) Natural marble is used not only as a building material but also in various other fields because its surface is polished to reveal a deep pattern and has excellent decorative properties. However, it is expensive due to the small amount of production. Therefore, in recent years, it has been widely practiced to obtain artificial marble that has an appearance similar to natural marble by incorporating fillers into acrylic resin or unsaturated polyester resin, but such conventional artificial marble has a pattern pattern. However, it was monotonous and lacked a sense of reality, and its uses were limited.
本発明は、かかる現況に鑑み、より実物感のある人造大
理石の提供を目的とし、高級インテリア素材としての使
用等その用途拡大を図らんとするものである。In view of the current situation, the present invention aims to provide artificial marble with a more realistic appearance and to expand its use, such as use as a high-quality interior material.
（問題点を解決するための手段）
本発明の人造大理石は、混合物の総量を基準として、液

混合物を、有機過酸化物の存在下に重合してなることを
特徴とする。(Means for Solving the Problems) The artificial marble of the present invention has a liquid resin binder of 20 to 60% by weight, preferably 25 to 3% by weight, based on the total amount of the mixture.
5% by weight, 40-80% by weight of white inorganic filler fine powder, preferably 60-70% by weight, and 0.1 mica fine particles.
-10% by weight, preferably 2-6% by weight, and this mixture is polymerized in the presence of an organic peroxide.
液状の樹脂結合材は、アクリル系樹脂シロップあるいは
不飽和ポリエステル樹脂であり、これらは、得られる人
造大理石の外観に深みを与える透明性を具え、かつ注型
に適した粘度を有する。The liquid resin binder is an acrylic resin syrup or an unsaturated polyester resin, which has a transparency that gives depth to the appearance of the resulting artificial marble and a viscosity suitable for casting.
白色無１ａ質充填材の微粉末は、得られる人造大理石の
外観に、天然大理石に近似した深みのある白っぽさを与

６５程度である。なお、白色無１ａ質充填材の微粉末の
粒径を５〜４０μの範囲のものとしたばあい、最も良好
な深みが得られる。The fine powder of the white non-alpha filler is essential for giving the resulting artificial marble a deep whitish appearance similar to that of natural marble, and its whiteness is 80 or higher and the refractive index is 80 or higher. The ratio is 1.55 to 1.55, which is close to that of the resin binder.
It is about 65. Note that the best depth can be obtained when the particle size of the fine powder of the white non-la-la filler is in the range of 5 to 40 microns.

できる。Furthermore, examples of the white inorganic filler include calcium carbonate, calcium silicate, silica, magnesium hydroxide,
Fine powders of talc, kaolin, clay, etc. can be used.
樹脂結合剤の配合割合および白色無機質充填材の配合割
合は、夫々、前記のごと＜２０〜６０重量％、４０〜８
０重量％であるが、樹脂結合剤の配合割合が２０重量％

（特に耐衝撃性）の良好な成形品とならないからである
。The blending ratio of the resin binder and the blending ratio of the white inorganic filler are <20 to 60% by weight and 40 to 8% by weight, respectively, as described above.
0% by weight, but the blending ratio of the resin binder is 20% by weight.
If the blending ratio of the white inorganic filler exceeds 80% by weight, the viscosity of the composition will increase, making it difficult to obtain a uniform composition, making it difficult to mold, as well as impairing the appearance and physical properties (especially This is because the molded product will not have good impact resistance).
一方樹脂結合剤の配合割合が６０重量％を越えると、又

なるからである。On the other hand, if the proportion of the resin binder exceeds 60% by weight, or if the proportion of the white inorganic filler is less than 40% by weight, the white inorganic filler and mica will settle, resulting in an appearance and physical appearance similar to natural marble. This is because the molded product will not have good physical properties.
雲母としては、白雲母（マスコバイト）又は金雲母（フ
ロゴバイト）の単独あるいはその両方を用いるものとし
、該白雲母には淡紅色のものと淡緑色のものとがある。As the mica, muscovite (muscovite) or phlogopite (phlogovite) may be used alone or both, and the muscovite includes light pink and light green.

なる。In addition, there are two types of phlogopite: light brown and dark green. The fine pieces of mica used in the present invention are fine pieces of mica with a flake diameter of about 50 μm to 200 μm or less. The refractive index is about 1.55 to 1.58, which is close to the refractive index of the resin binder. The fine pieces of mica are
Because it has good affinity with the liquid resin binder mentioned above,
In the resulting artificial marble, the mica particles are uniformly dispersed, and since the mica fine particles have a thin plate shape due to the crystal structure of mica, their arrangement is irregular. The blending ratio of the mica is 0.1 to 10% by weight, and 0.1% by weight.
If it is less than that, the mica will have poor texture and it will be difficult to obtain a molded product with a deep appearance. On the other hand, 10% by weight
If it exceeds this value, the pattern created by mica becomes intense, making it difficult to obtain a molded product exhibiting a rich spotted color pattern in a three-dimensional window.
