海洋構造物にも使用されている。防藻板の貼り付けは、
一般に、釘、接着剤、粘着材を用いて行なわれている。Cupronickel is an alloy of copper mixed with 10 to 30% nickel, and has superior corrosion resistance compared to copper. Algae-proof plates are used not only for ship hulls but also for various marine structures such as buoys, floating bridges, and water pipes. Pasting the algae-proof board,
Generally, this is done using nails, adhesives, or adhesives.

抗て防藻板が剥がれることもある。(Problem to be Solved by the Invention) By the way, since the surface of a marine structure, especially a ship's hull, is not flat, it takes a lot of effort to attach algae-proof plates. In addition, the algae-proof plates may peel off due to vibrations of the hull or water resistance.
この発明は、防藻板を後で貼り付けるのではなく、初め

藻板lを直に骨組laで支持することができる。(Means for Solving the Problems) A method of manufacturing a plastic structure covered with an algae-proof plate according to the present invention is to place an algae-proof plate molded to fit the inner surface of a linear shape on the inner surface of a mold, (Example) F To explain the case of RP ships,
As shown in FIG. 1, the mold 1 is composed of a framework 1a and a mold plate 1b. A cupronickel algae-proof plate 2 (thickness, for example, around 0.5+I1) is placed on the inner surface of this mold l.The algae-proof plate 2 is pressed in advance and formed to fit the inner surface of the mold l. ing. In addition, when the thickness of the algae-proof board 2 is large, no template is required under the algae-proof board, and the algae-proof board l can be directly supported by the framework la.

1) Layer the reinforcing mats and add FRP layer 3 of the required thickness.
(see Figure 2), what is important at this time is that F
The purpose is to adhere the RP layer 3 to the algae prevention board 2. For this reason, it is preferable that the algae-proof board 2 has a rough surface.
こうして、硬化後、離型すれば、第3図に示すように、
船底が防藻板2で覆われたFRP船ができ上がる。If the mold is released after curing in this way, as shown in Figure 3,
An FRP ship whose bottom is covered with algae-proof plate 2 is completed.

品が得られる。FIG. 4 shows the case of rotary molding a hollow body. A pre-formed algae-proofing plate 12 of cupronickel is placed on the inner surface of a mold 11, a plastic raw material 13 is put in, and the molds are orthogonally disposed in a heating furnace. Rotate around two axes. The raw material resin 13 is melted by heat and adheres to the entire surface of the algae-proof board. When cooled, the plastic 13 is bonded to the algae-proof plate 12, and when removed from the mold 11, a plastic molded product integrated with the algae-proof plate is obtained.
