Description
本発明の課題は、防汚構造及びその製造方法を提供することにある。
(1)表面に防汚構造を有する合成皮革は、宿泊施設専用のボールペンで書くことが困難である上、一般の油性ペン及び水性ペンでも書くことが困難であり、万一書かれた場合でも乾いた布で拭き取るだけでほとんど消すことができる。また、市販されている洗剤又はアルコール溶液を用いて拭き取れば、汚れが完全に無くなり、合成皮革材料表面の見た目を元の状態に戻すことができる。
(5)水性防汚層及び耐アルコール層を含む防汚構造により覆われた合成皮革材料は、アルコール溶液及び市販の洗剤により30回以上繰り返し拭かれても、防汚性能は下がり始めない。
図1を参照する。図1に示すように、実施例1に係る防汚構造10は、耐アルコール層12と、耐アルコール層12上に形成された水性防汚層13と、を含む。本実施例において防汚構造10は、基材20上に位置する。耐アルコール層12は、水性防汚層13と基材20との間に位置する。
(a)基材20上に耐アルコール組成物を塗布し、90~120℃の環境下で1~5分間乾燥させ、耐アルコール層12を形成する。
(b)耐アルコール層12上に水性防汚組成物を塗布し、140℃以上の環境下で1~5分間乾燥させ、水性防汚層13を形成する。
実施例1-2の防汚構造及びその製造工程は、実施例1-1と略同じであるが、実施例1-2の耐アルコール層は、耐アルコール組成物Bが硬化されて形成され、耐アルコール組成物Bの組成成分は上述した表1に示す通りであり、水性防汚層は、水性防汚組成物Bが硬化されて形成され、水性防汚組成物Bの組成成分は、上述した表2に示す通りである点が異なる。
実施例1-3の防汚構造及びその製造工程は、実施例1-1と略同じであるが、実施例1-3の耐アルコール層は、耐アルコール組成物Cが硬化されて形成され、耐アルコール組成物Cの組成成分は上述した表1に示す通りであり、水性防汚層は、水性防汚組成物Cが硬化されて形成され、水性防汚組成物Cの組成成分は、上述した表2に示す通りである点が異なる。
実施例2-1の防汚構造は、実施例1-1と類似し、耐アルコール層と、耐アルコール層上に形成された水性防汚層と、を含む。本実施例において、防汚構造は、基材上に位置する。耐アルコール層は、水性防汚層と基材との間に位置する。
(a)基板上に耐アルコール組成物を塗布し、90~130℃の環境下で1~5分間乾燥させ、耐アルコール層を形成する。
(b)耐アルコール層上に水性防汚組成物を塗布し、140℃以上の環境下で1~5分間乾燥させ、水性防汚層を形成する。
実施例2-2の防汚構造及びその製造工程は、実施例2-1と略同じであるが、実施例2-2の耐アルコール層は、耐アルコール組成物Eが硬化されて形成され、耐アルコール組成物Eの組成成分は上述した表3に示す通りであり、水性防汚層は、水性防汚組成物Eが硬化されて形成され、水性防汚組成物Eの組成成分は、上述した表4に示す通りである点が異なる。
実施例2-3の防汚構造及びその製造工程は、実施例2-1と略同じであるが、実施例2-3の耐アルコール層は、耐アルコール組成物Fが硬化されて形成され、耐アルコール組成物Fの組成成分は上述した表3に示す通りであり、水性防汚層は、水性防汚組成物Fが硬化されて形成され、水性防汚組成物Fの組成成分は、上述した表4に示す通りである点が異なる。
上述した実施例1-1~1-3及び2-1~2-3の防汚構造に対して試験を行った。まず、所定の汚染物で実施例1-1~1-3及び2-1~2-3の防汚構造を汚染させ、所定時間が経ってから拭き取り、汚れの残り具合を評価した結果は以下の表5の通りであった。
レベル5:汚れが全くない
レベル4:軽微な汚れ
レベル3:目立つ汚れ
レベル2:酷い汚れ
レベル1:酷すぎる汚れ
(1)市販されている大部分のメーカー合成皮革加工の防汚材料のほとんどは二液型溶剤架橋樹脂を主とし、その成分には有機溶剤が含まれるため、揮発性有機化合物(Volatile Organic Compounds:VOC)が揮発する問題があった。
(2)市販されている皮革上に用いる防汚材料は高硬度樹脂に属するが、本発明の防汚構造に用いる水性PUは低硬度樹脂であるため、高硬度溶剤型樹脂を軟質皮革材料に加工する際、耐折曲げ性に問題が生じる虞がない。
(5)市販されている大部分のメーカーの合成皮革加工の防汚材料は、一般によく見かける合成皮革のように加工は容易でない。
(6)本発明の防汚構造は、水性防汚層及び耐アルコール層の結合により、保護層の強度が高いため、アルコール溶液により30回以上繰り返し拭き取っても、その防汚性能が低下することはない。
(1)原料に使用する水性PU樹脂の余肉部分を回収添加使用することができる。
(2)無味無毒なため、環境に与える悪影響が少なく、地球環境を守る。
(3)高温のエンボス加工を行っても耐黄変性を有する上、焦げた匂いもなく、VOCが放出される問題もない。
