Title (EN) POLYURETHANE RESIN FOR SYNTHETIC LEATHER
(FR) RÉSINE DE POLYURÉTHANE POUR CUIR SYNTHÉTIQUE
(JA) 合成皮革用ポリウレタン樹脂
Abstract:
(EN) The present invention pertains to a polyurethane resin (D) for synthetic leather containing, as essential constituent monomers: a polycarbonate diol (A1) comprising a structural unit originating from an alkane diol (a1) comprising eight or more carbon atoms; a polycarbonate diol (A2), other than (A1), comprising a structural unit originating from an alkane diol (a3) comprising four to six carbon atoms, and/or a polyester diol (A3); an organic diisocyanate (B); and a chain extender (C). The polyurethane resin satisfies the following conditions (1) and (2). (1) The polycarbonate diol (A1) has a heat of fusion (ΔH) of 40 to 100 J/g, as determined according to the method set forth in JIS K 7121-1987. (2) The polycarbonate diol (A2) and polyester diol (A3) have heats of fusion (ΔH) of 35 J/g or less, as determined according to the method set forth in JIS K 7121-1987.
(FR) La présente invention concerne une résine de polyuréthane (D) pour cuir synthétique contenant, en tant que monomères constitutifs essentiels : un polycarbonate diol (A1) comprenant un motif structural issu d'un alcane diol (a1) comprenant huit atomes de carbone ou plus ; un polycarbonate diol (A2), autre que (A1), comprenant un motif structural issu d'un alcane diol (a3) comprenant quatre à six atomes de carbone, et/ou un polyester diol (A3) ; un diisocyanate organique (B) ; et un allongeur de chaîne (C). La résine de polyuréthane satisfait les conditions (1) et (2) suivantes. (1) Le polycarbonate diol (A1) a une chaleur de fusion (ΔH) de 40 à 100 J/g, telle que déterminée selon le procédé décrit dans JIS K 7121-1987. (2) Le polycarbonate diol (A2) et le polyester diol (A3) ont des chaleurs de fusion (ΔH) de 35 J/g ou moins, telles que déterminées selon le procédé décrit dans JIS K 7121-1987.
(JA) 本発明は、炭素数8以上のアルカンジオール(a1)に由来する構造単位を有するポリカーボネートジオール(A1)と、炭素数4~6のアルカンジオール(a3)に由来する構造単位を有する上記(A1)以外のポリカーボネートジオール(A2)及び/又はポリエステルジオール(A3)と、有機ジイソシアネート(B)と、鎖伸長剤(C)とを必須構成単量体とするポリウレタン樹脂であって、下記(1)~(2)の条件を満足する合成皮革用ポリウレタン樹脂(D)に関する。 (1)上記ポリカーボネートジオール(A1)のJIS K7121-1987に規定される方法により求められる融解熱量(ΔH)が40~100J/gである。 (2)上記ポリカーボネートジオール(A2)及びポリエステルジオール(A3)のJIS K7121-1987に規定される方法により求められる融解熱量(ΔH)が35J/g以下である。
