Description

本発明は、ポリカーボネート樹脂積層体、屋根、屋外看板および外壁に関する。   The present invention relates to a polycarbonate resin laminate, a roof, an outdoor signboard, and an outer wall.

ポリカーボネート樹脂は、耐衝撃性、耐熱性、軽量性に優れ、幅広い分野で使用されている。中でも、透明微粒子を配合して光拡散性を付与した白色ポリカーボネート樹脂板は、色調と光拡散性に優れ、建材、看板用途等に使用されている。(例えば、特許文献1参照。)
ポリカーボネート樹脂は、耐候性に優れておらず、建材、看板等の屋外用途では、色調変化、耐衝撃性の低下を防ぐため、耐候処理が必須となる。
従来、ポリカーボネート樹脂の耐候処理には、耐候性に優れたアクリルフィルムをラミネートする方法が中心であったが、近年ではポリカーボネート樹脂に紫外線吸収剤を添加した耐候層を共押出成形法にて積層一体化する方法が中心となっている。特に建材用途では、アクリルフィルムラミネートの場合、経年劣化によるアクリルフィルムの剥離が発生しやすいことから、共押出法による耐候処置が望ましい。
しかしながら、基材層が白色の樹脂に対して共押出成形法で紫外線吸収剤を添加した耐候層を積層した場合、紫外線吸収剤が持つ黄色味が基材層の白色によって強調され、積層体が非常に黄色くなり、色調に優れていない状態となる。基材層の青味を強くして表層の黄色味を打ち消そうとした場合、積層体に黒みが生じ、色調に優れていない状態となる。
このため、白色ポリカーボネート樹脂板に関しては、耐候処理はアクリルフィルムラミネートにて行われてきた。
Polycarbonate resins are excellent in impact resistance, heat resistance and light weight, and are used in a wide range of fields. Especially, the white polycarbonate resin board which mix | blended transparent microparticles | fine-particles and provided light diffusivity is excellent in a color tone and light diffusibility, and is used for building materials, a signboard use, etc. (For example, refer to Patent Document 1.)
Polycarbonate resin is not excellent in weather resistance, and weathering treatment is essential for outdoor use such as building materials and signboards in order to prevent changes in color tone and deterioration in impact resistance.
Conventionally, the weathering treatment of polycarbonate resin has been centered on the method of laminating an acrylic film with excellent weather resistance, but in recent years, a weathering layer in which an ultraviolet absorber is added to the polycarbonate resin is laminated by a coextrusion molding method. The method of making it is the center. Particularly in the case of building materials, in the case of an acrylic film laminate, since the acrylic film is likely to be peeled off due to aging, a weathering treatment by a coextrusion method is desirable.
However, when a weather resistant layer in which a UV absorber is added to a white resin with a base material layer is co-extruded, the yellow color of the UV absorber is emphasized by the white color of the base material layer, It becomes very yellow and the color tone is not excellent. When the blueness of the base material layer is strengthened to try to cancel the yellowness of the surface layer, the laminate is blackened and the color tone is not excellent.
For this reason, with respect to the white polycarbonate resin plate, the weathering treatment has been performed by acrylic film lamination.

本発明において、ポリカーボネート樹脂積層体の押出成形に適用される共押出成形法には、通常に熱可塑性樹脂製の多層性の製造に用いられる公知の共押出成形法が採用され、フラットなTダイが適用される。この場合のTダイの方式は、加熱溶融状態の樹脂組成物がTダイ流入前に積層されるフィードブロック方式、あるいは樹脂材料がTダイ内部で積層されるマルチマニホールド方式が好適に採用できる。   In the present invention, as a coextrusion molding method applied to the extrusion molding of a polycarbonate resin laminate, a known coextrusion molding method usually used for the production of multilayers made of thermoplastic resin is adopted, and a flat T die is used. Applies. In this case, the T-die method can suitably employ a feed block method in which a heat-melted resin composition is laminated before inflow of the T-die, or a multi-manifold method in which resin materials are laminated inside the T-die.

本発明において、ポリカーボネート樹脂積層体における表層部の厚さは、5μm以上120μm以下とする。この場合、上記の範囲以下では、耐候層の厚みが薄く基材層が紫外線劣化してしまい、上記の範囲以上では、表層部の色目が目立ち、積層体の色調に悪影響を及ぼす。好ましくは、樹脂積層体における表層部の厚さは、10μm以上100μm以下である。   In this invention, the thickness of the surface layer part in a polycarbonate resin laminated body shall be 5 micrometers or more and 120 micrometers or less.
