３） ホットメルトで接着する方法
が実際に行われている。
Conventionally, for example, a fixing method between fiber bodies made of a thermoplastic resin or a thermoplastic resin material used for automobile parts,
1) Method of adhering with an adhesive 2) Method of stopping with a tucker needle (staple) 3) Method of adhering with hot melt is actually performed.
しかしながら、これらの方法では、以下述べる問題点があった。即ち、
１）の方法は、塗布・乾燥の作業や工程が必要であり、即効性がない。
２）の方法は、点固定にしかならず、又リサイクル時にはタッカー針と熱可塑性材料と の分離が必要となり、その作業が煩雑である。
３）の方法は、リサイクル時に、ホットメルトとの分離が困難であり、又塗布設備が高 価である。
However, these methods have the following problems. That is,
The method 1) requires a coating and drying operation and process, and is not immediately effective.
The method 2) is not only point fixing but also requires separation of the tucker needle and the thermoplastic material at the time of recycling, which is complicated.
The method 3) is difficult to separate from the hot melt during recycling, and the coating equipment is expensive.
そして、これらに代わるものとして、熱可塑性樹脂や熱可塑性樹脂素材からなる繊維体同士の固定方法として、熱融着する手段が考えられる。
４） 熱風による熱融着する方法
５） 高周波ウェルダーを用いる方法
６） 超音波ウェルダーを用いる方法
７） 振動ウェルダーを用いる方法
８） スピンウェルダーを用いる方法
９） 瞬間加熱ウェルダーを用いる方法
である。
As an alternative to these, as a method of fixing fiber bodies made of a thermoplastic resin or a thermoplastic resin material, a means for heat-sealing can be considered.
4) Method of heat fusion with hot air 5) Method of using high frequency welder 6) Method of using ultrasonic welder 7) Method of using vibration welder 8) Method of using spin welder 9) Method of using instantaneous heating welder.
しかし、これらの方法も次に述べる欠点があった。
４）の方法によると、ピンポイント加熱が困難であること。また、加熱に時間が必要で あること。
５）の方法によると、ＰＶＣ（塩ビ）のような極性の強い樹脂しか使えないし、溶かし 痕が表に出るし、設備がコスト高になる。
６）の方法によると、溶かし痕が表に出るし、そのための設備がコスト高になる。
７）の方法によると、固い樹脂しか使用できず、そのための設備がコスト高になる。
８）の方法によると、丸くて軽いものしか使えない。接着が不安定となり、そのための 設備がコスト高となる。
９）の方法によると、溶かし痕が表に出るし、そのための設備がコスト高となる。
However, these methods also have the following drawbacks.
According to the method 4), pinpoint heating is difficult. Also, it takes time for heating.
According to the method 5), only a highly polar resin such as PVC (polyvinyl chloride) can be used, and melt marks appear on the surface, resulting in high cost of equipment.
According to the method 6), melt marks appear on the surface, and the equipment for that purpose is expensive.
According to the method 7), only a hard resin can be used, and the equipment for that is expensive.
According to the method of 8), only round and light can be used. Adhesion becomes unstable, and the equipment for it becomes expensive.
According to the method 9), melted marks appear on the surface, and the equipment for that purpose is expensive.
そこで、この発明は、リサイクルが可能であり、作業時間の短縮が図れ、強い接着強度の確保と、接着強度コントロールが可能であり、表面には溶かした痕が出ず、安価な生産コストで製造できる熱可塑性材料の熱溶着方法を開発・提供するものである。 Therefore, the present invention can be recycled, shortening the work time, ensuring strong adhesive strength and controlling adhesive strength, producing no traces of melting on the surface, and manufacturing at low production costs. It is intended to develop and provide a thermal welding method for thermoplastic materials.
この発明による熱可塑性材料の熱溶着方法は、熱可塑性材料を、被接着材として設け、これら被接着材間に、被接着材の融点より高温加熱した金属コテを挟み込み、これらの上から荷重をかけて金属コテ接触部分を溶融させ、荷重をかけた状態で金属コテを引抜き、所定時間保持することにより被接着材を一体化させることを特徴とする熱可塑性材料の熱溶着方法である。 According to the method for thermally welding a thermoplastic material according to the present invention, a thermoplastic material is provided as an adherend, a metal iron heated at a temperature higher than the melting point of the adherend is sandwiched between the adherends, and a load is applied from above. This is a method for thermally welding a thermoplastic material, characterized in that a metal iron contact portion is melted, the metal iron is pulled out in a state where a load is applied, and the adherend is integrated by holding for a predetermined time.
この発明によると、接着剤は使用せず、接触加熱のため、即加熱が可能であり、金属コテの面積により、ある程度の面接着が可能であり、しかも、接着面を直接加熱することにより、堅牢に接着でき、しかも、設備にコストがかからない等、極めて有益なる効果を奏する。 According to the present invention, no adhesive is used, and because of contact heating, immediate heating is possible, and due to the area of the metal iron, a certain degree of surface bonding is possible, and by directly heating the bonding surface, It can be firmly bonded and has extremely beneficial effects such as no cost for equipment.
そして、この発明によると、荷重をかけた状態で金属コテを引抜くため、金属コテに付着する融着物を拭き取る作業も同時に出来、セルフクリーニングが行えるものである。 And according to this invention, since a metal iron is pulled out in the state which applied the load, the operation | work which wipes off the fusion | bonding material adhering to a metal iron can be performed simultaneously, and self-cleaning can be performed.
さらに、タッカー針等の異種材料がないため、この熱溶着方法で接着された熱可塑性材料を廃棄する際には、リサイクル化がし易いし、そのコストも安価にできる。 Further, since there is no different material such as a tucker needle, when the thermoplastic material bonded by this heat welding method is discarded, it is easy to recycle and the cost can be reduced.
