Abstract:
(EN) The purpose of the invention is to provide a curable composition that yields a cured article having high tensile strength and high elongation. The curable composition of the invention is a polyurethane curable composition that uses as essential structural components a polyol (A) and a polyisocyanate (B), characterized by containing 1-150 parts by mass of polymer fine particles (C) having a core-shell structure having at least two layers (a core layer and a shell layer) relative to 100 total parts by mass of component (A) and component (B), by the glass transition temperature (Tg) of the core layer of component (C) calculated by numerical formula (1) below being higher than 0°C, and by the elongation at maximum tensile stress of a cured article formed from the curable composition being more than 47%. 1/Tg=Σ(M/Tg) (1) (In the formula, M represents the weight fraction of the non-crosslinkable monomer i component constituting the core layer of component (C), and Tg represents the glass transition temperature (K) of a homopolymer of the non-crosslinkable monomer i; i represents an integer of 1 or higher.)
(FR) La présente invention concerne une composition durcissable qui permet d'obtenir un objet durci présentant une résistance élevée à la traction et un allongement élevé. La composition durcissable de l'invention est une composition durcissable de polyuréthane qui utilise, en tant que constituants structuraux, essentiels un polyol (A) et un polyisocyanate (B), caractérisée en ce qu'elle contient 1-150 parties en masse de fines particules polymères (C) présentant une structure noyau-enveloppe présentant au moins deux couches (une couche de noyau et une couche d'enveloppe), par rapport à un total de 100 parties en masse de constituant (A) et de constituant (B), en ce que la température de transition vitreuse (Tg) de la couche de noyau du constituant (C), calculée par la formule numérique (1) ci-dessous, est supérieure à 0°C et en ce que l'allongement à la contrainte de traction maximale d'un objet durci formé à partir de la composition durcissable est supérieur à 47 %. 1/Tg = =Σ(Mi/Tgi) (1) (Dans la formule, Mi représente la fraction pondérale du constituant monomère non réticulable i constituant la couche de noyau du constituant (C) et Tgi représente la température de transition vitreuse (K) d'un homopolymère du monomère non réticulable i ; i représente un nombre entier de 1 ou plus.)
(JA) 本発明は、高引張強度及び高伸びを示す硬化物となる硬化性組成物を提供することを目的とする。本発明の硬化性組成物は、ポリオール(A)とポリイソシアネート(B)を必須構成成分として用いたポリウレタン系硬化性組成物であって、(A)成分と(B)成分の総量100質量部に対して、更に、コア層およびシェル層の少なくとも2層を有するコアシェル構造を有するポリマー微粒子(C)1~150質量部を含有し、下記数式(1)より計算した(C)成分のコア層のガラス転移温度(Tg)が0℃より大きく、かつ、前記硬化性組成物から形成される硬化物の最大引張応力時の伸びが47%超であることを特徴とする。1/Tg=Σ(M/Tg) (1)(式中、Mは(C)成分のコア層を構成する非架橋性単量体i成分の重量分率、Tgは非架橋性単量体iのホモポリマーのガラス転移温度(K)を表す。iは1以上の整数を表す。)
