らないという問題点を有している。(Problem M to be Solved by the Invention) However, the former laminate molded product made of a colored gel coat layer and FRPl does not have an excellent texture, that is, it deforms when struck in a bathtub, and there is a problem that it lacks a luxurious feel. In particular, when creating a bathtub, the 7-rung part was deformed and the product lacked a luxurious feel. On the other hand, bathtubs made by a casting method in which a resin concrete layer is poured using a convex mold and a concave mold have a problem in that two molds must be used during molding.

が用いられる。Here, the gel coat layer is a thin synthetic resin layer that forms the surface of the product, and is transparent or almost transparent, and is usually made only of resin, with fillers mixed in. It gives the product gloss, heat resistance, stain resistance, and water resistance. , a layer that provides scratch prevention function. As the above-mentioned transparent resin, unsaturated polyester resins may be used, particularly bisphenol-based or isophthalic acid-based unsaturated polyester resins which have been used conventionally and have various properties such as hot water resistance, depending on the purpose. This formation method is
This is usually done by applying a mold release agent to a mold (wooden mold, FRP mold, metal mold, etc.) that has the surface shape of the product and spraying it. The thickness is suitably in the range of about 0.3 to 0.6 mm, and the viscosity of 1800 to 3000 cps is excellent in workability, and silica, styrene monomer, and organic thixotropic agent are used to adjust the viscosity.
繊維強化プラスチック層は通常ガラス繊維などに不飽和
ポリエステル樹脂を含浸させて形成される。厚みは用途
に応じて２〜８ｍｍの範囲で選ばれてよい。The fiber-reinforced plastic layer is usually formed by impregnating glass fiber or the like with an unsaturated polyester resin. The thickness may be selected within the range of 2 to 8 mm depending on the application.
レジンコンパウンド層は強度を持たせる目的で、透明樹

る反透明層として調整される。The resin compound layer is composed of a transparent resin containing 60% by weight or more of a filler in order to provide strength, and is a fairly thick layer, and is adjusted as a transparent, opaque, or anti-transparent layer that slightly transmits light.

応じて２〜ｇｍｍの範囲で選はれてよい。As the transparent resin, unsaturated polyester resin may be used as in the surface layer. As the filler, glass frit, aluminum hydroxide, carbonate, and other materials can be used. In particular, we use soft resin with an elongation rate of 20% or more, a Young's modulus of 500 kg/mm2 or less, and a linear expansion coefficient of 2.0X.
It is preferable to set it to 1O-' or less. Further, the thickness may be selected within the range of 2 to gmm depending on the application.
（作用効果）
本発明は、上記ゲルコート層およびＦＲＰ層の裏面にレ
ジンコンパウンド層を構成したので、質感が向上する。(Effects) In the present invention, a resin compound layer is provided on the back surface of the gel coat layer and the FRP layer, so that the texture is improved.

２０％程度低下することがわかる。That is, even if the laminate is pressed, it does not deform and produces a profound sound. By the way, there is a 3m FRP layer on the gel coat layer.
Comparing the one formed only with mrn and the one with an additional resin compound layer of 5 mrn or 8 mm, it can be seen that the sound pressure level of the present invention is lower by about 20% as shown in Figure 4. .
耐水性や耐薬品性などの性能は、従来のＦＲＰ層と同じ
であり、実用に値するものが作成できる。Performances such as water resistance and chemical resistance are the same as conventional FRP layers, and it is possible to create something that is of practical use.
さらに、機械的強度に関しては、従来の積層体に比へ裏
面の剛性を有する板状物の分だけ強くなる。Furthermore, in terms of mechanical strength, it is stronger than conventional laminates due to the rigidity of the plate-like material on the back side.

さくして変形を防止することができる。Moreover, by using the above-mentioned soft resin, the Young's modulus of the resin compound layer can be set to 500 kg/n+m2 or less, and the linear expansion coefficient can be set to 2.0XlO-' or less.
Deformation can be prevented by making the curing and aging shrinkage forces smaller than the shape retention force of the P laminate.
また、ＦＲＰ層の裏面にレジンコンパウンド層ヲ形成す
るから、凸型のみを使用して作成することができる。Furthermore, since a resin compound layer is formed on the back side of the FRP layer, it can be created using only a convex mold.
（実施例） 以下、本発明の実施例を添付図面に基ついて説明する。(Example) Embodiments of the present invention will be described below with reference to the accompanying drawings.

化後、凸型より脱型することにより浴槽を得た。A predetermined amount of a curing agent and a curing accelerator were added to a pre-colored bis-based unsaturated polyester resin (colored gel coat resin), and the mixture was applied in a convex manner to a thickness of 0.4 mm using a spray gun. The resin was cured at 60°C for 130 minutes. Thereafter, a transparent iso-unsaturated polyester resin was laminated together with the cut glass fibers of the roving by a spray-up method (thickness: 2 nm). After that, unsaturated polyester resin (product name UPICA 8660AP)
, elongation rate 64%) 100 parts by weight and 300% carbonate
A resin compound layer having a composition of 0 parts by weight, 0 parts by weight of Si, and 5 parts by weight of powder is laminated to a thickness of 5) by a hand lay-up method. This resin compound layer has a Young's modulus of 360 kg.
/mm'', coefficient of linear expansion!, 5X10-'. After curing of the resin, the mold was removed from the convex mold to obtain a bathtub.
