（産業上の利用分野）
本発明は特に金属鋼管の腐蝕防止のために金属鋼接着剤
層付き積層管に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention particularly relates to a laminated pipe with a metal steel adhesive layer for preventing corrosion of the metal steel pipe.
（従来技術とその課題）
従来、熱可塑性合成樹脂管に溶融型接着剤層を共押出し
によって積層した積層管の接着剤層の肉厚を管理する場

接着剤層を剥離し、膜厚計で肉厚を測定し、接着剤層の
膜厚か規定範囲内にあるか否かを確認していた。(Prior art and its issues) Conventionally, when controlling the thickness of the adhesive layer of a laminated tube in which a molten adhesive layer is laminated on a thermoplastic synthetic resin tube by coextrusion, it is necessary to measure the thickness of the adhesive layer. Cut the laminated body while it is running, apply force, twist, and cut between the outer layer and inner layer, smooth the solvent into the cut, peel off the inner adhesive layer with tweezers, and measure the thickness using a film thickness meter. The thickness was measured to confirm whether the thickness of the adhesive layer was within a specified range.
然るに、このような厚み測定方法では接着剤層のは剥ぎ
とりに熟練度を必要とするのみならす、積層体が押出さ

。However, with this thickness measurement method, peeling off the adhesive layer requires skill, and the adhesive layer cannot be peeled off after a certain amount of time has elapsed and cooled down after the laminate is extruded. During that time, there was Zhao. Moreover, since the adhesive layer is colorless and transparent, there is a problem in that it is impossible to visually confirm whether or not the inner adhesive layer is laminated.

The laminated tube is characterized in that it has a colored adhesive layer formed thereon.
以下、本発明を更に詳細に説明する。The present invention will be explained in more detail below.

ることが好ましい。As the resin for the thermoplastic synthetic resin pipe used in the present invention, appropriate thermoplastic synthetic resins such as polyvinyl chloride, polyethylene, polypropylene, and polystyrene can be employed. In addition, hot-melt adhesives to be laminated on thermoplastic synthetic resin pipes include polyolefin copolymers such as EVA, polyamide, polyester, ethylene acrylic acid copolymer, acrylic acid-modified polyethylene, maleic anhydride-modified polyethylene, and rosin. Adhesives containing tackifier resins such as rosin derivatives, terpene resins, petroleum resins, and colorants are preferably used, but any heat-melting adhesive can be used. The type of colorant added to the hot-melt adhesive is not particularly limited, as long as it has appropriate dispersibility for the hot-melt adhesive, and in addition to the colorant, a small amount of dispersant, lubricant, etc. may be used in combination. It is preferable to do so.

着剤層を有する本発明の積層管か得られる。According to the method of the present invention, if a thermoplastic synthetic resin, for example, a polyvinyl chloride resin layer and a colorant-containing hot-melt adhesive layer are coextruded using a tubular die so as to form an inner layer or an outer layer, the hot-melt adhesive layer will be colored. The laminated tube of the present invention is obtained by extrusion and having a colored adhesive layer on the inner or outer surface.

された状態で目視すれはよい。(Effect of the invention) As described above, by providing a colored hot-melt adhesive layer on the inner or outer surface of a thermoplastic synthetic resin pipe as in the present invention, the thickness of the colored adhesive layer changes. Therefore, the relationship between WA thickness and saturation is measured in advance, and the saturation is measured on-site using a color difference meter to ensure adhesion without peeling the inner or outer adhesive layer. You can check the thickness of the agent layer. Furthermore, if no colorant is added to the hot-melt adhesive layer, it will be extruded colorless and transparent. Therefore, it is very easy to visually determine whether the product is defective or non-defective. In addition, when a colored layer is provided on the inner layer, it is easy to visually inspect the synthetic resin pipe in a cut state.
