【発明の詳細な説明】
本発明は、FRP（繊維強化プラスチツク）線
への接着性樹脂被覆方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for coating FRP (fiber reinforced plastic) wire with adhesive resin.
FRP線の表面に熱可塑性接着性樹脂を被覆し
たものは、電気ケーブルや光ケーブル等のテンシ
ヨンメンバーとして使用されている。この場合、
熱可塑性接着性樹脂はケーブルのプラスチツクシ
ースとFRP線の接着剤として作用する。 FRP wires coated with thermoplastic adhesive resin are used as tension members for electrical cables, optical cables, etc. in this case,
The thermoplastic adhesive acts as an adhesive between the cable's plastic sheath and the FRP wire.
従来、FRP線への接着性樹脂の被覆は、FRP
線の表面に接着性樹脂を押出被覆することにより
行つていた。 Conventionally, coating FRP wire with adhesive resin was
This was done by extrusion coating the surface of the wire with an adhesive resin.
しかし、この方法には次のような欠点がある。 However, this method has the following drawbacks.
(1) 熱可塑性接着性樹脂は一般的に高流動性で低
粘度であり、それ故、押出加工により肉厚を均
一に被覆することが困難である。また、線速を
高くすると肌荒れ（メルトフラクチヤ、フイツ
シユアイ）が発生するため、製品の商品価値が
低下するだけでなく、高線速化が妨げられ生産
性が上がらない。(1) Thermoplastic adhesive resins generally have high fluidity and low viscosity, so it is difficult to coat them with a uniform thickness by extrusion processing. In addition, when the line speed is increased, roughness (melt fracture, hard eye) occurs, which not only reduces the commercial value of the product, but also prevents higher line speeds and prevents productivity from increasing.
(2) 熱可塑性接着性樹脂は一般的に極性基を有し
ているため、押出機のバレル、スクリユーある
いは成型用ダイスに付着し易く、長時間の連続
運転が困難で生産性が悪い。(2) Since thermoplastic adhesive resins generally have polar groups, they tend to adhere to the barrel, screw, or molding die of an extruder, making long-term continuous operation difficult and poor productivity.
(3) １台の押出機で、多本数のFRP線に同時に
押出被覆することは困難である。(3) It is difficult to extrude and coat a large number of FRP wires at the same time using one extruder.
本発明の目的は、上記のような問題点をなく
し、生産性の高いFRP線への接着性樹脂被覆方
法を提供するものである。 An object of the present invention is to provide a highly productive method for coating FRP wire with adhesive resin, which eliminates the above-mentioned problems.
この目的を達成するため、本発明は、FRP線
の表面に、熱可塑性接着性樹脂をエマルジヨン化
してなる樹脂エマルジヨン又は熱可塑性接着性樹
脂を溶剤で溶解してなる樹脂溶液を塗布した後、
それを固化させることを特徴とするものである。 In order to achieve this object, the present invention applies a resin emulsion formed by emulsifying a thermoplastic adhesive resin or a resin solution formed by dissolving a thermoplastic adhesive resin with a solvent to the surface of an FRP wire, and then
It is characterized by solidifying it.
本発明に用いられるFRP線としては、全体が
FRPで構成される通常のFRP線の他、FRP線の
内部（特に中心部が好ましい）に光フアイバを内

ビニル系、ポリビニルアルコール系、ポリビニル
アセタール系、アクリル系、ポリアミド系、ポリ
オレフイン系などの樹脂を用いることができる。 The entire FRP wire used in the present invention is
In addition to normal FRP wires made of FRP, it is also possible to use FRP wires with optical fibers built inside them (especially preferably in the center). Further, as the thermoplastic adhesive resin, resins such as vinyl acetate, vinyl chloride, polyvinyl alcohol, polyvinyl acetal, acrylic, polyamide, and polyolefin can be used.
以下、本発明の実施例を図面を参照して詳細に
説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

can be dissolved in a mixed solvent of benzene, toluene and xylene, or a metal ionomer dissolved in xylene can be used. When using a resin solution, the viscosity can be adjusted by changing the amount of solvent, and although it is related to the linear speed, the higher the viscosity, the thicker the coating layer can be formed.
ダイス４は、樹脂エマルジヨン又は樹脂溶液の
付着量を均一にするためのもので、通常の金属製
ダイス以外にも、熱硬化性樹脂板又はFRP板に

で火災が発生しないように注意する必要がある。 The heating furnace 5 uses infrared rays (including far infrared rays)
Furnaces such as type, steam type, and cast-in heater type can be used, but when using a resin solution, care must be taken to prevent fire from occurring due to the volatilized solvent.
第１図ではFRP線１本掛けの例を示している

ことができる。 FIG. 2 shows another embodiment of the present invention, in which the same parts as in FIG. 1 are given the same reference numerals. The difference between this embodiment and the embodiment shown in Fig. 1 is that an FRP wire forming process is provided before the process of applying resin emulsion or resin solution to the FRP wire 2, and the FRP wire forming process and coating process are performed in tandem. That's what I did. In the forming process of the FRP wire 2, glass rovings 8 supplied from a large number of supply stands 7 are collected, passed through a thermosetting resin tank 9, and then passed through a drawing die 10, and then heated in a heating furnace 11. It consists of curing a curable resin. In this case, as the thermosetting resin, epoxy resin or unsaturated polyester resin can be used.

が簡単であるので、設備費も安価である。 According to the present invention, since the thermoplastic adhesive resin coating is provided on the surface of the FRP wire by coating, the roughening phenomenon that occurs during extrusion coating does not occur, and the wire speed can be improved. It also becomes possible to coat multiple FRP wires at the same time, greatly improving productivity. Furthermore, since the device is simple, the equipment cost is also low.
