Title (EN) LAMINATED SHEET
(FR) FEUILLE STRATIFIÉE
(JA) 積層シート
Abstract:
(EN) The present invention pertains to a laminated sheet comprising a laminated structure in which a first damping layer (2) is laminated on the upper surface of a polycarbonate layer (1), whereas a second damping layer (3) is laminated on the undersurface of said polycarbonate layer, wherein the first and second damping layers are each composed of a sheet-like formed body of a polyester resin composition that comprises: a thermoplastic polyester resin (A) comprising a component that includes a dicarboxylic acid component and a diol component; a component (B) that is a plasticizer and/or an elastomer; and an inorganic filler (C). The laminated sheet according to the present invention has sufficient stiffness and impact strength because of having the polycarbonate layer therein, and furthermore exhibits an excellent damping effect because of having a high loss coefficient, and therefore, this laminated sheet can be suitably used as a material for audio equipment such as speakers, televisions, radio-cassette recorders, headphones, audio components, and microphones, or as a damping material for products such as appliances, vehicles, architectural structures, and industrial machines, or components thereof, or casings thereof.
(FR) La présente invention concerne une feuille stratifiée, laquelle feuille comprend une structure stratifiée dans laquelle une première couche d'amortissement (2) est stratifiée sur la surface supérieure d'une couche de polycarbonate (1), tandis qu'une seconde couche d'amortissement (3) est stratifiée sur la surface inférieure de ladite couche de polycarbonate, les première et seconde couches d'amortissement étant chacune constituées par un corps formé sous la forme d'une feuille d'une composition de résine de polyester qui comprend : une résine de polyester thermoplastique (A) comprenant un composant qui comprend un composant d'acide dicarboxylique et un composant de diol ; un composant (B) qui est un plastifiant et/ou un élastomère ; et une charge minérale (C). La feuille stratifiée selon la présente invention a une rigidité et une résistance à l'impact suffisantes du fait qu'elle a la couche de polycarbonate dans celle-ci, et elle présente en outre un excellent effet d'amortissement du fait qu'elle a un coefficient de perte élevé, et, par conséquent, cette feuille stratifiée peut être utilisée de manière appropriée en tant que matériau pour un équipement audio tel que des haut-parleurs, des télévisions, des radiocassettes, des écouteurs, des composants audio et des microphones, ou en tant que matériau d'amortissement pour des produits tels que des accessoires, des véhicules, des structures architecturales et des machines industrielles, ou des composants de ceux-ci, ou des enceintes de ceux-ci.
(JA) 本発明は、ポリカーボネート層(1)の上面に第一の制振層(2)が、及び該ポリカーボネート層の下面に第二の制振層(3)が積層された積層構造からなる積層シートであって、第一の制振層及び第二の制振層が、ジカルボン酸成分とジオール成分とを含む成分から構成される熱可塑性ポリエステル樹脂(A)、可塑剤及び/又はエラストマーである成分(B)、並びに無機充填剤(C)を含有してなるポリエステル樹脂組成物のシート状成形体である、積層シートに関する。本発明の積層シートはポリカーボネート層を有するために十分な剛性と衝撃強度を有し、それだけでなく損失係数が高いため制振効果に優れているので、例えばスピーカー、テレビ、ラジカセ、ヘッドフォン、オーディオコンポ又はマイク等の音響機器の材料や電気製品、乗物、建築物、産業用機器等の製品又はそれらの部品、筐体用の制振材料として好適に使用することができる。
