Abstract
Description
この実施形態は、洗浄容易保護フィルムを提供する。図1に示すように、洗浄容易保護フィルムは、金属基材、非金属基材又は金属コーティング層を保護するためのPVC底部フィルム1と、二酸化ケイ素粒子からなる(二酸化ケイ素層とも呼ばれる)洗浄容易層2とを含む。ここで、金属コーティング層自体の色及び輝きに影響を及ぼさないように、PVC底部フィルム1として透明なPVCキャストフィルムを使用することができる。
この実施形態は、洗浄容易保護フィルムを提供する。図2に示すように、洗浄容易保護フィルムは、金属基材、非金属基材又は金属コーティング層を保護するために使用されるPVC底部フィルム1と、二酸化ケイ素粒子からなる洗浄容易層2とを含む。PVC底部フィルム1と洗浄容易層2との間には、それらの間の結合力を高めるように、ポリウレタン(PU)からなる(ポリウレタン層とも呼ばれる)結合層3が配置される。ここで、この実施形態のPVC底部フィルム1、二酸化ケイ素層、及びポリウレタン層の原材料は、全て市販されている。
この実施形態は、以下の工程を含む、洗浄容易保護フィルムを準備する方法を提供する。
(1)透明PVCキャストフィルムの表面をSn触媒含有ポリウレタン溶液でコーティングし、110〜120℃で3.5分〜5分間硬化させて、ポリウレタン層、すなわち結合層を形成した。次いで、コロナ処理を200mj/cm2の条件で行った。
(2)ポリウレタン層を二酸化ケイ素分散液でコーティングし、110〜120℃で3.5分〜5分間硬化させて、二酸化ケイ素層、すなわち洗浄容易層を形成した。
この試験方法(1)は、塵汚れによる汚染前後の試料の光沢を調べることによって、試料の耐塵性能を評価し、(2)油汚れにより汚染される前及び清浄後の試料の光沢及び色差を調べることによって、試料の油汚れ清浄性効果を評価した。
汚染される前の試料の光沢G1を光沢試験装置を用いて測定し、次いで、乾燥塵汚れで試料を覆い、光沢試験装置を用いて汚染後の試料の光沢G2を測定した。
汚染前の試料の光沢H1を光沢試験装置を用いて測定し、次いで、油汚れで試料を覆った。洗浄機で水溶液の洗浄剤を用いて試料を洗浄し、光沢試験装置を用いて洗浄後の試料の光沢H2を測定した。
デルタE=((L−L’)2+(a−a’)2+(b−b’)2)1/2
試料8:透明PVCキャストフィルムを、200mj/cm2の条件下でコロナ処理し、次いで、その透明PVCキャストフィルムの表面に二酸化ケイ素層を形成した。ここで、PVCキャストフィルムの厚さは50μmであり、二酸化ケイ素層の厚さは200nmであり、二酸化ケイ素の粒径は2nmであった。
この実施形態は、コーティングによって形成されたコーティング層が配置された基材を備える基材アセンブリを提供する。上記の実施形態による洗浄容易保護フィルムは、コーティング層に取り付けられる。
この実施形態は、上記の実施形態による洗浄容易保護フィルムが取り付けられた基材を備える基材アセンブリを提供する。
