化粧シートの連続的製造方法に関する。TECHNICAL FIELD The present invention relates to a long decorative sheet and a continuous method for producing the same, and more particularly to a continuous decorative sheet which is thin and has excellent durability such as flexibility and strength. A continuous press-molding press is used to heat-bond a long press-bonded decorative sheet and a core paper that is impregnated and coated with a thermosetting resin such as phenol resin, which has excellent flexibility and strength, on the back surface of the decorative paper not impregnated with resin. And a continuous manufacturing method of a long decorative sheet integrally bonded.
従来、家具用又は化粧壁用の化粧シートは、大別して次
に掲げるようなものがある。Conventionally, the decorative sheets for furniture or decorative walls are roughly classified as follows.
(イ)塩化ビニル樹脂、ポリエチレン又はポリプロピレン
などの熱可塑性樹脂から成る化粧シート。以下、これを
従来の化粧シート(イ)という。(A) A decorative sheet made of a thermoplastic resin such as vinyl chloride resin, polyethylene or polypropylene. Hereinafter, this is referred to as a conventional decorative sheet (a).
(ロ)化粧紙裏面にクラフト紙などの樹脂未含浸コアー紙
を酢酸ビニルエマルジョン又は尿素樹脂などの接着剤を
介して接合した化粧シート。以下、これを従来の化粧シ
ート(ロ)という。(B) A decorative sheet in which resin-impregnated core paper such as kraft paper is bonded to the back surface of the decorative paper via an adhesive such as vinyl acetate emulsion or urea resin. Hereinafter, this is referred to as a conventional decorative sheet (B).
(ハ)不織布又はクロス布などの表面に模様を施した化粧
クロス布を基材とした化粧シート。以下、これを従来の
化粧シート(ハ)という。(C) A decorative sheet based on a decorative cloth cloth whose surface is a non-woven cloth or cloth cloth. Hereinafter, this is referred to as a conventional decorative sheet (C).
上記従来の化粧シート(イ)は、可塑性、柔軟性に優れる
長所を有するが耐熱性、耐薬品性に乏しい欠点がある。The conventional decorative sheet (a) has the advantages of excellent plasticity and flexibility, but has the drawback of poor heat resistance and chemical resistance.
また、従来の化粧シート(ハ)は、外観上暖味がありソフ
