Abstract:
(EN) The purpose of the present invention is to provide expandable polystyrene resin particles which are capable of suppressing scraping noise without contaminating a pre-expanding machine or a molding die, and which enable the achievement of a foam molded body that exhibits excellent fusion properties. The purpose is able to be achieved by expandable polystyrene resin particles which are formed from a styrene monomer and a polysiloxane-containing macromonomer, and which are characterized in that: an external additive that has a melting point of 40°C or higher is contained therein; and a foam molded body that is obtained by pre-expanding and subsequently molding the expandable polystyrene resin particles has a coefficient of static friction of 4.0 or less.
(FR) L'objet de la présente invention est de pourvoir à des particules de résine polystyrène expansibles qui sont capables d'éliminer le bruit de raclage sans contaminer une machine de pré-expansion ou une filière de moulage, et qui permettent d'obtenir un corps moulé en mousse qui présente d'excellentes propriétés de fusion. Le but est atteint par des particules de résine polystyrène expansibles qui sont formées à partir d'un monomère de styrène et d'un macromonomère contenant un polysiloxane, et qui sont caractérisées par : l'incorporation d'un additif externe ayant un point de fusion de 40 °C ou plus ; et par un corps moulé en mousse obtenu par pré-expansion, puis moulage des particules de résine polystyrène expansibles ayant un coefficient de frottement statique de 4,0 ou moins.
(JA) 本発明は、予備発泡機や成形金型を汚染することなく擦れ音を抑制でき、さらに、融着性に優れた発泡成形体が得られる発泡性ポリスチレン系樹脂粒子を提供することを目的とする。スチレン系単量体とポリシロキサン含有マクロモノマーとからなる発泡性ポリスチレン系樹脂粒子であって、融点40℃以上の外添剤を含み、発泡性ポリスチレン系樹脂粒子を予備発泡し成形することで得られる発泡成形体の静止摩擦係数が4.0以下であることを特徴とする発泡性ポリスチレン系樹脂粒子により達成できる。
