The tank part has a transparent gel coat layer, a colored gel coat layer, and an FRP layer laminated from the surface side, and the handrail part has a transparent gel coat layer, an FRTP (fiber reinforced thermoplastic resin) layer having a different hue from the FRP layer, and the above layer from the front side. Characterized by laminated FRP layers
After spraying a transparent gel coat resin onto the mold surface of the FRP bathtub and the FRP bathtub mold, and before the transparent gel coat resin hardens, the FRP is separately molded so as to be able to fit into the handrail molding part of the mold. The hue is different from the layer.
An FRP characterized in that the FRTP molded body is brought into close contact with the handrail molded part, and then a colored gel coat resin is sprayed on at least the surface of the transparent gel coat resin layer, and then the FRP is sprayed up.
The gist is a method for manufacturing a bathtub.
［作用］
本発明によれば、槽部と手摺部との色相が異な
るFRP浴槽が、一体成形品として提供される。[Function] According to the present invention, an FRP bathtub in which the tub part and the handrail part have different hues is provided as an integrally molded product.
このため、槽部と手摺部との継ぎ目がないこと
から、従来品の如く、接合部の存在による美観喪
失等の問題がなく、しかも衛生的である。 Therefore, since there is no seam between the tank part and the handrail part, unlike conventional products, there is no problem such as loss of aesthetic appearance due to the presence of a joint part, and it is also hygienic.
しかして、このような本発明のFRP浴槽は、
本発明の方法により、一体成形で、極めて効率的
に製造される。 However, such an FRP bathtub of the present invention,
By the method of the invention, it is produced in one piece and very efficiently.
［実施例］
以下、図面を参照して本発明の実施例について
説明する。[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.
第１図は本発明のFRP浴槽１を示す部分断面
図である。 FIG. 1 is a partial sectional view showing an FRP bathtub 1 of the present invention.
第１図に示す如く、本発明のFRP浴槽１は、
槽部２及び手摺部３を有し、槽部２は表面側から
透明ゲルコート層４、着色ゲルコート層５及び
FRP層６が積層され、手摺部３は表面側から透
明ゲルコート層４、FRTP層７及びFRP層６が
積層された構造とされている。 As shown in FIG. 1, the FRP bathtub 1 of the present invention includes:
It has a tank part 2 and a handrail part 3, and the tank part 2 has a transparent gel coat layer 4, a colored gel coat layer 5, and a colored gel coat layer 5 from the surface side.
The FRP layer 6 is laminated, and the handrail portion 3 has a structure in which the transparent gel coat layer 4, the FRTP layer 7, and the FRP layer 6 are laminated from the front side.
なお、図示の実施例においては、手摺部３の
FRTP層７とFRP層６との間に、着色ゲルコー
ト層５が介在されているが、手摺部３の着色ゲル
コート層５はなくても良い。 In addition, in the illustrated embodiment, the handrail portion 3 is
Although the colored gel coat layer 5 is interposed between the FRTP layer 7 and the FRP layer 6, the colored gel coat layer 5 of the handrail portion 3 may not be provided.
各層の材質等については特に制限はないが、例
えば、透明ゲルコート層４としては不飽和ポリエ
ステル樹脂等の透明性樹脂、着色ゲルコート層５
としては、不飽和ポリエステル樹脂やその他の樹
脂に所望の色調を呈する顔料を配合したもの、ま
た、FRP層６としては、不飽和ポリエステルに
適当量、例えば全FRP重量の50〜80％程度のガ
ラス繊維等を混合したものなどが挙げられる。
FRTP層７としては、アクリル樹脂、ABS樹脂
に、適当量、例えば全FRTP重量の50〜80％程度
のガラス繊維等を混合し、必要に応じて更に所望
の色調を呈する顔料や大理石粉等を配合したもの
などが挙げられる。 There are no particular restrictions on the material of each layer, but for example, the transparent gel coat layer 4 may be a transparent resin such as unsaturated polyester resin, the colored gel coat layer 5 may be a transparent resin such as an unsaturated polyester resin, etc.
For the FRP layer 6, unsaturated polyester resin or other resin is blended with a pigment that gives the desired color tone, and for the FRP layer 6, unsaturated polyester is mixed with an appropriate amount of glass, for example, about 50 to 80% of the total FRP weight. Examples include those mixed with fibers and the like.
The FRTP layer 7 is made by mixing an appropriate amount of glass fiber, etc., for example, about 50 to 80% of the total FRTP weight, with acrylic resin or ABS resin, and if necessary, adding pigments, marble powder, etc. that give the desired color tone. Examples include those that have been blended.
各層の形状や大きさ等は、FRP浴槽の形状、
大きさ等に応じて以下の通り、美観、強度等を考
慮して適宜決定される。 The shape and size of each layer depends on the shape of the FRP bathtub,
Depending on the size, etc., the size is determined as appropriate, taking into consideration aesthetics, strength, etc., as shown below.
透明ゲルコート層４や着色ゲルコート層５はあ
まりに厚過ぎるとコスト高となる上に、透明ゲル
コート層４については、その透明度による深み、
高級感を損なう結果となる場合がある。また、こ
れらの装飾のための層は、薄過ぎても十分な深
み、色調を呈することができないことがある。従
つて、透明ゲルコート層４の厚さａは0.1〜１mm、
着色ゲルコート層５の厚さｂは0.1〜１mmの範囲
で適宜決定するのが好ましい。 If the transparent gel coat layer 4 and the colored gel coat layer 5 are too thick, the cost will increase, and the transparent gel coat layer 4 has a depth due to its transparency.
This may result in a loss of luxury. Furthermore, if these decorative layers are too thin, they may not be able to exhibit sufficient depth and color tone. Therefore, the thickness a of the transparent gel coat layer 4 is 0.1 to 1 mm.
The thickness b of the colored gel coat layer 5 is preferably determined as appropriate in the range of 0.1 to 1 mm.
一方、FRP層６は、FRP浴槽の強度を担う意
味から、そのFRP自体の強度を勘案して、ある
程度の厚みを持たせるが、厚過ぎても製品重量が
大きくなり、コスト的にも不利となる。このた
め、一般には、FRP層６の厚さは１〜５mm程度
とする。 On the other hand, since the FRP layer 6 is responsible for the strength of the FRP bathtub, it should be made to have a certain degree of thickness considering the strength of the FRP itself, but if it is too thick, the product weight will increase and it will be disadvantageous in terms of cost. Become. Therefore, the thickness of the FRP layer 6 is generally about 1 to 5 mm.
手摺部３のFRTP層７は、通常、手摺部３の上
面３ａと、側面３ｂに若干かぶさるように設け

面略コ字形とされるが、その両端部以外の厚さｄ

の断面コ字形のFRTP層７の側面３ｂに延出する
部分があまりに長いと、手摺部の色相の異なる部
分が槽部２にまで及ぶようなものとなり、槽部２
に色の境界線ができ、槽部２の美観を損なう。従
つて、側面３ｂに延出する部分、即ち、FRTP層
７の端部の厚さｅは５cm以下、好ましくは２cm以
下とするのが良い。 The FRTP layer 7 of the handrail section 3 is usually provided so as to slightly cover the top surface 3a and side surface 3b of the handrail section 3. For this reason, the FRTP layer 7 has a substantially U-shaped cross section as shown in FIG.
is 5 mm or less, preferably about 1 to 4 mm. If the portion of this U-shaped FRTP layer 7 extending to the side surface 3b is too long, the portion of the handrail portion with a different hue will extend to the tank portion 2.
A color boundary line is formed on the surface, spoiling the beauty of the tank section 2. Therefore, the thickness e of the portion extending to the side surface 3b, that is, the end portion of the FRTP layer 7 is preferably 5 cm or less, preferably 2 cm or less.
次に、このような本発明のFRP浴槽を、本発

コート樹脂２１に接着される。 In the method of the present invention, an FRP bathtub molding mold 20 having a desired shape as shown in FIG. 4a is used,
First, a transparent gel coat resin 21 is sprayed onto the mold surface 20a. Separately, the handrail molding portion 20 of the molding die 20
The FRP molded body 22 is molded into a shape that can fit into the handrail molded part 20b before the transparent gel coat resin 21 hardens. When the transparent gel coat resin 21 is not yet cured, the FRTP molded body 22 is placed in the handrail molding part 20 of the mold 20.
By setting the temperature to b, the solvent such as styrene contained in the transparent gel coat resin 21 makes the surface of the thermoplastic resin of the FRTP molded body 22 a little sticky. As a result, the FRTP molded body 22 is adhered to the transparent gel coat resin 21 with good adhesion.
FRTP成形体２２を取り付けた後、第４図ｂの

ようにする方が有利である場合が多い。 The colored gel coat resin 23 is as shown in FIG. 4b.
It may be provided so as to cover the entire surface of the transparent gel coat resin layer 21 and the FRTP molded body 22, or it may be provided in a portion other than the FRTP molded body 22. From the viewpoint of simplifying the manufacturing process, it is often advantageous to cover the entire surface as shown in FIG. 4b.
このようにして成形した後、脱型し、常法に従
