いるが、その反面、次のような問題があった。As a typical example of this type of rock-patterned molded product, there is known a resin concrete press-molded product in which a thermosetting resin is mixed with powdery aggregates, reinforcing fibers, a catalyst and the like. Since such a molded product has a granite pattern on its surface and has a relatively good appearance, it is often used as a wall material or the like, but on the other hand, it has the following problems.

た。That is, when obtaining a molded article made of resin concrete as described above, usually a thermosetting resin is added to the powder granules, reinforcing fibers,
Since a method is adopted in which the catalyst and the like are uniformly mixed to form a dumpling, which is placed in a mold of a press molding machine and heated and pressed, a thin molded product is obtained in relation to the fluidity of the mixture. However, there is a problem that the strength is inferior even if a thin molded product can be obtained. Therefore, the conventional molded articles made of resin concrete are all thick and heavy, which is inconvenient to carry and handle, and the amount of materials used is large, resulting in a high cost.
〔問題を解決するための手段〕 上記の問題を解決するため、本発明の岩石調模様入り成

レス成形することを特徴としている。[Means for Solving the Problem] In order to solve the above problem, the method for producing a rock-patterned molded article of the present invention comprises a mixed powder-grain aggregate for rock-pattern formation on SMC with a substantially constant thickness. And pressurize the aggregate to SM
It is characterized in that it is embedded in C and this SMC is pressed so that the embedded surface of the aggregate is the outer surface.

きな強度を有する成形品となる。By press-molding the SMC with the mixed powder-grain aggregate embedded in the surface in this way, it is possible to thicken the SMC by considering the fluidity of the molding material in the mold as in the case of conventional resin concrete molded products. It is not necessary to make a molded product, it is possible to obtain a thin molded product corresponding to the thickness of SMC. Moreover, since SCM is a material that is substantially the same as high-strength FRP, it has a large strength even if it is thin. It becomes a molded product having.
以下、図面を参照しながら本発明の実施例を詳述する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
第1a図乃至第1c図は本発明製造方法の一実施例の各工程
の説明図であって、これによれば、第1a図に示すように
最初の骨材散布工程において配合粉粒骨材１がSMC2の上
にほぼ一定の厚さに散布される。FIGS. 1a to 1c are explanatory views of each step of one embodiment of the manufacturing method of the present invention, according to which, as shown in FIG. 1 is sprinkled on SMC2 to a nearly constant thickness.
この配合粉粒骨材１は、所望の岩石調模様が形成される

高粘度にしたものの方がより好適に使用される。更に、
SMCの厚みについては１〜10mm程度が望ましい。1mmより
薄いものを使用する場合は、次の骨材埋込み工程で配合
粉粒骨材１をSMCに埋込むことが難しく、得られる成形
品の強度も不足するといった不都合があり、他方、10mm
より厚いものを使用する場合は、強度が必要以上に大き
くなるので無駄になるからである。This mixed powder-grain aggregate 1 is a mixture of various coarse sands, fine sands, rock-forming mineral grains, etc. in an appropriate ratio so that a desired rock-tone pattern is formed. In the case of forming, one having a composition in which 1 part of black stone is mixed with 3 parts of cold water stone is preferably used. In addition, SMC2 is a sheet in which uncured unsaturated polyester resin contains glass fiber, a curing agent, various additives, etc., and a commercially available product (for example, Dainippon Ink and others) may be used. However, in the case of the present invention, the amount of aggregate is less than that of the commercially available product,
The one having a high viscosity is more preferably used. Furthermore,
The thickness of SMC is preferably about 1 to 10 mm. When using a material thinner than 1 mm, it is difficult to embed the mixed powder / aggregate 1 in the SMC in the next step of embedding the aggregate, and the strength of the obtained molded product is insufficient. On the other hand, 10 mm
This is because if a thicker one is used, the strength will be unnecessarily increased and it will be wasted.
配合粉粒骨材１を散布する厚さは、SMC2の厚みの約1/2
以下の範囲とするのが望ましい。該骨材１をこれ以上厚
く散布して次の工程でSMC2に埋込むと、該SMC2の骨材含
有量が過剰となって成形品の強度定価を招く虞があるか
らである。尚、骨材１の散布層の厚み調整は、例えばド
クターブレード等を使用して行えばよい。The thickness of the mixed powder / aggregate 1 is about 1/2 of the thickness of SMC2.
The following range is desirable. This is because if the aggregate 1 is sprayed thicker than this and embedded in the SMC2 in the next step, the aggregate content of the SMC2 becomes excessive, which may lead to a fixed price of the strength of the molded product. The thickness of the scatter layer of the aggregate 1 may be adjusted using, for example, a doctor blade.

することが望ましい。The SMC 2 on which the mixed powder / aggregate 1 is sprinkled as described above is then subjected to pressure rolls 3, 3 in the aggregate embedding step shown in FIG. 1b.
And mixed powder granulated aggregate 1 is SMC2 by the roll pressure.
Is buried in the surface layer of. In that case, rather than applying a large roll pressure to completely embed the powder mixture aggregate 1 in the SMC2, a part of the powder mixture aggregate 1 is exposed and remains on the surface of the SMC2 as shown in the figure. It is desirable to adjust the roll pressure so as to achieve the state.

い。The SMC 2 in which the mixed powder / aggregate 1 is embedded in this way is arranged between the upper and lower molds 4a, 4b of the press molding machine in the press molding process shown in FIG. 1c, and the aggregate embedding surface is The molded article is press-molded under heating so as to be the outer surface of the molded article and cured to obtain a desired thin molded article. Also in this press molding step, it is desirable to adjust the press pressure so that a part of the mixed powder / aggregate 1 is exposed on the surface of the SMC 2.

あり、材料使用量も少ないので経済的である。As shown in FIG. 2, the molded product A obtained by the above-described manufacturing method has the mixed powder / aggregate 1 partially embedded in the outer surface layer of the press-molded cured SMC2 ′. A granite or other beautiful rock-like pattern is formed on the outer surface by the aggregate 1. In this way, compound powder aggregate 1
Embedded in the outer surface layer of the hardened SMC2 ′, most of the natural light is blocked by the aggregate 1 and the photodegradation of the hardened SMC2 ′ is considerably suppressed, so that it is more weather resistant than the SMC single molded product. The property is improved. Further, since the cured SMC2 'has substantially the same high mechanical strength as FRP, the molded product A will not be easily broken even if it is thin. Moreover, since such a thin molded product A is lightweight, it is easy to carry and handle, and the amount of material used is small, which is economical.
成形品Ａの形状は、この実施例では断面コ字形の凸板状

接着剤又は止具等で取付固定される。In this embodiment, the shape of the molded product A is a convex plate shape having a U-shaped cross section, but the shape is not limited to this, and a concave plate shape, a corrugated plate shape, an uneven plate shape, or any other desired shape capable of press molding. It goes without saying that it can be formed into a shape. The convex plate-shaped molded product A as shown in FIG. 2 is preferably used for construction of a decorative wall having a rock-tone pattern, and is fitted to the base material 5 on the wall surface of the house to be used as an adhesive or a fastener. It is mounted and fixed with.

Compared to molded products made from
The effect is that the transportability, handleability, and economic efficiency are greatly improved.
