産業上の利用分野
本発明は、熱成形性に優れた布貼りポリオレフィン系シ
ートの製造法に関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for producing a cloth-covered polyolefin sheet having excellent thermoformability.
従来の技術
従来、布貼りポリオレフィン系シートは、ポリオレフィ
ン系シートに布を熱溶着したり、接着剤で一体化するこ
とにより製造されている。BACKGROUND OF THE INVENTION Conventionally, cloth-covered polyolefin sheets have been manufactured by thermally welding cloth to a polyolefin sheet or integrating the cloth with an adhesive.
発明が解決しようとする問題点
しかし、上記の布貼りポリオレフィン系シートは、布と
ポリオレフィン系シートの間の剥離強度か十分でなく、
真空成形やプレス成形等の熱成形に供すると、布が剥が
れ易い。Problems to be Solved by the Invention However, the above cloth-covered polyolefin sheet does not have sufficient peel strength between the cloth and the polyolefin sheet.
When subjected to thermoforming such as vacuum forming or press forming, the cloth tends to peel off easily.
本発明は、十分な剥離強度を有し、熱成形時の延伸にお
いても剥かれることがない布貼りポリオレフィン系シー
トを提供することを目的とする。An object of the present invention is to provide a cloth-covered polyolefin sheet that has sufficient peel strength and does not peel off even during stretching during thermoforming.
問題点を解決するための手段
上記目的を達成するために、本発明は、ポリオレフィン
系シートと布とを熱可塑性エラストマ層を介在させて熱
溶着することを特徴とする。Means for Solving the Problems In order to achieve the above object, the present invention is characterized in that a polyolefin sheet and a cloth are thermally welded with a thermoplastic elastomer layer interposed therebetween.
作用
本発明においては、ポリオレフィン系シートと熱可塑性
エラストマ層は熱溶着により強固に接着される。また、
布は熱可塑性エラストマ層への投錨効果に（熱可塑性エ
ラストマの溶融粘度が低いことを利用）より強固に一体
化される。Function: In the present invention, the polyolefin sheet and the thermoplastic elastomer layer are firmly adhered by thermal welding. Also,
The fabric is more tightly integrated into the thermoplastic elastomer layer due to its anchoring effect (taking advantage of the thermoplastic elastomer's low melt viscosity).
これによって、布とポリオレフィン系シートの剥離強度
は向上し、熱成形にも適したものとなる。This improves the peel strength between the cloth and the polyolefin sheet, making it suitable for thermoforming.
実施例 次に、本発明の詳細な説明する。Example Next, the present invention will be explained in detail.
