COMPOSITION AMORTISSEUSE DE CHOCS POUR CHAUSSURES, ET ÉLÉMENT AMORTISSEUR DE CHOCS POUR CHAUSSURES
(JA)
履物用緩衝組成物及び履物用緩衝部材
Abstract:
(EN)
Provided are: a cushioning composition for footwear which includes a lightweight styrene-based thermoplastic elastomer and forms cushioning members that not only have excellent adhesiveness (peel strength) but also have low hardness and excellent mechanical strength (in particular, tensile strength); and a cushioning member for footwear which is obtained from the cushioning composition. The cushioning composition for footwear comprises a styrene-based thermoplastic elastomer (A) and a softener (B), wherein the styrene-based thermoplastic elastomer (A) comprises: a block copolymer (a1) obtained by hydrogenating a block copolymer X-Y-X; and a modified styrene/ethylene/butylene/styrene block copolymer (a2). The block copolymer X-Y-X comprises: blocks X located at both terminals and each comprising a styrene polymer block; and an intermediate block Y comprising a styrene/butadiene copolymer block. The block copolymer (a2) is an amine-modified block copolymer or a maleic-anhydride-modified block copolymer. The block copolymers a1 and a2 have been blended so that a2/(a1+a2)=0.25-0.95 by weight. The styrene-based thermoplastic elastomer (A) and the softener (B) have been blended so that B/(A+B) = 0.5 to 0.7 by weight.

L'invention fournit une composition amortisseuse de chocs pour chaussures qui se compose d'un élastomère thermoplastique à base de styrène léger, et qui est destinée à former un élément amortisseur de chocs excellent à la fois en termes d'adhérence (résistance au pelage) et de résistance mécanique (particulièrement, en termes de résistance à la rupture) à un faible degré de dureté, et l'invention fournit également un élément amortisseur de chocs pour chaussures mettant en œuvre cette composition. La composition amortisseuse de chocs pour chaussures comprend l'élastomère thermoplastique à base de styrène (A) et un solvant (B). L'élastomère thermoplastique à base de styrène (A) est constitué : d'un copolymère séquencé (a1) tel qu'un copolymère séquencé X-Y-X est soumis à une hydrogénation, lequel copolymère séquencé X-Y-X est constitué d'une séquence à deux terminaisons X constituée d'une séquence de polymère de styrène, et d'une séquence intermédiaire Y constituée d'une séquence de copolymère de styrène et butadiène; et d'un copolymère séquencé styrène-éthylène-butylène-styrène modifié (a2). Le copolymère séquencé (a2) consiste en un copolymère séquencé modifié par une amine ou en un copolymère séquencé modifié par un anhydride maléique. La proportion dans laquelle les copolymères séquencés (a1) et (a2) sont mélangés est comprise entre a2/(a1+a2)=0,25 et 0,95, dans un rapport massique, et la proportion dans laquelle l'élastomère thermoplastique à base de styrène (A) et le solvant (B) sont mélangés est comprise entre B/(A+B)=0,5 et 0,7, dans un rapport massique.
