に構成したので、次のような効果が得られる。 As explained above, according to this invention,
A transparent resin sheet that is compatible with the transparent resin to be extruded is bonded to at least the outer surface of the metal foil to form a composite laminate, which is roll-formed, and then a transparent resin is extruded around it by extrusion molding. Since it is configured to form a transparent resin layer that is coated, melted, and integrated, the following effects can be obtained.
透明樹脂シートが金属箔を保護するため、ロ
ール成形、押出成形時に直接金属箔表面に傷が
発生しない。 Since the transparent resin sheet protects the metal foil, there is no direct damage to the metal foil surface during roll forming or extrusion molding.
金属箔の裏面に傷が発生しても裏面で問題は
なく、また透明樹脂シートに発生しても、押出
成形時の溶融一体化により消滅し、外観的に問
題はない。 Even if scratches occur on the back side of the metal foil, there is no problem on the back side, and even if scratches occur on the transparent resin sheet, they disappear by melting and integrating during extrusion molding, and there is no problem in appearance.
透明樹脂シートの貼着により金属箔に剛性が
付与され、ロール成形時に十分な加圧を加える
ことができ、断面精度を出しやすく、かつロー
ルからの脱落や成形品のねじれ、そり、波打ち
等を防止できる。 Adhering a transparent resin sheet gives the metal foil rigidity, which allows sufficient pressure to be applied during roll forming, making it easier to achieve cross-sectional accuracy and preventing falling off from the roll, twisting, warping, and waving of the molded product. It can be prevented.
ロール成形品は透明樹脂シートにより剛性が
付与されているため、押出成形時における上下
樹脂圧の微少な差による偏曲等の影響を受ける
ことが少ない。 Since the roll-molded product is given rigidity by the transparent resin sheet, it is less susceptible to bending or the like due to minute differences in upper and lower resin pressures during extrusion molding.
透明樹脂層は剥離除去する必要はなく、押出
成形により溶融、一体化して均一で優れた外観
を有する透明樹脂層が形成される。 The transparent resin layer does not need to be peeled off and is melted and integrated by extrusion molding to form a transparent resin layer that is uniform and has an excellent appearance.
