The present invention relates to a resin pipe lamination molding method in which resin pipes are laminated to form a resin pipe.

３の剥離事故につながる。 Conventionally, in the production of large-diameter resin pipes, as shown in FIG. 1, an operator forms a resin layer 3 by laminating resin on the inner peripheral molding surface 2 of a mold 1 using a laminating roller. Then, the resin tube 4 was formed by laminating the resin tubes several times with an appropriate curing time. In this case, it is difficult to layer each resin layer 3 on the entire circumferential surface because it is not possible to visually determine which laminated part is currently cured, and generally It was divided into several parts and laminated. However, when each division is laminated and molded, as shown in FIG. 2, a boundary line is created between the other divided layers due to the difference in curing, and this boundary line is in a bonded state. In addition, impurities such as dust are attached to the boundary area. Furthermore, if the curing time is short, the top coat 5 will vaporize and become a paraffin surface. These factors lead to a peeling accident of the resin layer 3.
本発明の目的とするところは、積層ごとに全周
一体成形し得る樹脂管の積層成形方法を提供する
点にある。 An object of the present invention is to provide a method for laminating resin pipes in which the entire circumference of each layer can be integrally molded.
上記目的を達成するために本発明における樹脂
管の積層成形方法は、着色した樹脂を、各回ごと
に色を変えて積層する方法である。 In order to achieve the above object, the resin pipe lamination molding method according to the present invention is a method in which colored resin is laminated with a different color each time.

種々な問題点を解決することができる。 According to this method, it is possible to visually determine which laminated parts are hardened, and it is also possible to check whether any laminated parts have been forgotten. can be done. By being able to integrally mold the entire periphery in this way, various problems that occur during conventional divisional lamination can be solved.

一体成形される。 An embodiment of the present invention will be described below with reference to FIGS. 3 and 4. That is, when resin is laminated on the inner molding surface 11 of the mold 10 a plurality of times to form the resin tube 12, colored resin is laminated with a different color each time. For example, a top coat 13, a white corrosion-resistant resin layer 14, a green reinforced resin layer 15, a red reinforced resin layer 16, a black corrosion-resistant resin layer 17, and a top coat 18 are placed on the inner peripheral molding surface 11. The layers 14, 15, 16, and 17 are laminated in this order, and the layers 14, 15, 16, and 17 are integrally molded all around.

硬化状態の判別や積層が正常に行なわれているか
否かを目視によつて行なえる。 By such lamination, each layer 14, 15, 1
6 and 17 are color-coded, so that it is possible to visually determine the cured state and whether or not lamination is being performed normally.
なお色として、硬化すると変色する着色剤であ
