Description

本発明は、熱可塑性複合材の製造方法に関し、特に、熱可塑性フィルムと布材との結合を密にし、熱可塑性フィルムの表面に立体パターンを明確に形成し、熱可塑性複合材の構造を多様化することができる熱可塑性複合材の成型方法に関する。 The present invention relates to a method for producing a thermoplastic composite material, and in particular, the bonding between the thermoplastic film and the cloth material is made dense, a three-dimensional pattern is clearly formed on the surface of the thermoplastic film, and the structure of the thermoplastic composite material is diverse. The present invention relates to a method for molding a thermoplastic composite material that can be made into a material.

従来の熱可塑性複合材の成型方法として、本発明の発明者が発明した特許文献１が挙げられる。特許文献１は、ガイドローラ上に型シートが巻設される。型シートの外側は、凹凸パターンが形成されたパターン面を有する。押出機により、熱可塑性材料をガイドローラ上方の型シートのパターン面上に垂直に落とす。また、ガイドローラの一方の側部の回転ローラには、ベース布が巻設される。型シート、熱可塑性フィルム及びベース布がガイドローラと回転ローラとの接近点を通過することにより、３者が貼合され、型シートを取り除いた後、熱可塑性フィルムの表面に、凹凸パターンに対応する立体パターンが形成される。しかし、２つのローラを使用して型シートと熱可塑性フィルムとベース布とを結合して立体パターンを形成する方式の場合、結合性に劣る。また、生成される立体パターンも明確でない。この成型方法は、ベース布全体と熱可塑性フィルム全体とを完全に結合する熱可塑性複合材にのみ適用され、様々な形状のベース布上に様々な形状及び大きさの熱可塑性フィルムが結合される熱可塑性複合材を製造することができない。 As a conventional method for molding a thermoplastic composite material, Patent Literature 1 invented by the inventor of the present invention can be cited. In Patent Document 1, a mold sheet is wound around a guide roller. The outside of the mold sheet has a pattern surface on which an uneven pattern is formed. With an extruder, the thermoplastic material is dropped vertically onto the pattern surface of the mold sheet above the guide roller. A base cloth is wound around the rotation roller on one side of the guide roller. The mold sheet, the thermoplastic film and the base cloth pass through the approach point between the guide roller and the rotating roller, the three parties are bonded, and after removing the mold sheet, the surface of the thermoplastic film corresponds to the uneven pattern A three-dimensional pattern is formed. However, in the case of a system in which a three-dimensional pattern is formed by bonding a mold sheet, a thermoplastic film, and a base cloth using two rollers, the bonding property is inferior. Further, the generated three-dimensional pattern is not clear. This molding method is applied only to thermoplastic composites that completely bond the entire base fabric and the entire thermoplastic film, and various shapes and sizes of thermoplastic films are bonded onto various shapes of base fabric. A thermoplastic composite cannot be produced.

もう１つの従来の熱可塑性複合材の成型方法として、特許文献２が挙げられる。特許文献２は、上型及び下型により、布材と熱可塑性フィルムとを熱圧着するものである。この成型方法の場合、様々な形状の布材上に様々な形状及び大きさの熱可塑性フィルムが結合される熱可塑性複合材を製造することができる。しかし、単純に上型及び下型を使用して布材と熱可塑性フィルムとを熱圧着する方式の場合、結合性に劣る上、型上の凹凸パターンによって形成される立体パターンが明確でない。また、エアトラップが発生することにより、パターンの再現性に劣り、パターンが明確でない。 Patent document 2 is mentioned as another conventional molding method of a thermoplastic composite material. In Patent Document 2, a cloth material and a thermoplastic film are thermocompression bonded by an upper mold and a lower mold. In the case of this molding method, it is possible to produce thermoplastic composite materials in which thermoplastic films of various shapes and sizes are bonded onto various shapes of cloth materials. However, in the case of a system in which a cloth material and a thermoplastic film are simply thermocompression bonded using an upper mold and a lower mold, the bonding pattern is inferior and the three-dimensional pattern formed by the uneven pattern on the mold is not clear. In addition, the occurrence of an air trap results in poor pattern reproducibility and the pattern is not clear.

即ち、従来の熱可塑性フィルムと布材とを結合して熱可塑性複合材を形成する成型方式は、熱可塑性フィルムと布材との結合性に劣り、熱可塑性フィルム上に形成されるパターンが明確でなく、熱可塑性複合材の構造を多様化できない問題を有する。 In other words, the conventional molding method that combines a thermoplastic film and a cloth material to form a thermoplastic composite material is inferior in the bonding property between the thermoplastic film and the cloth material, and the pattern formed on the thermoplastic film is clear. In addition, there is a problem that the structure of the thermoplastic composite material cannot be diversified.
