Abstract

La présente invention concerne une composition d'ABS et un procédé pour sa préparation et une application correspondante, applicables à la fabrication d'un cadre avant d'un téléviseur. La composition d'ABS comprend les constituants suivants, en parties en poids : 48-93 parties de terpolymère d'acrylonitrile-butadiène-styrène, 0-20 parties de poly(méthacrylate de méthyle), 5-30 parties de poudre minérale et 0-10 parties d'un agent de renforcement. La composition d'ABS prend la poudre minérale en tant que charge et présente peu de fibres flottantes, de faibles dommages à un moule et une meilleure ténacité. De plus, étant donné que le coût de l'ABS est manifestement inférieur à celui du PC, la composition d'ABS est plus performante en termes de coût. Le cadre avant du téléviseur fabriqué à l'aide de la composition d'ABS présente de faibles coefficients de dilatation thermique linéaire et est également un produit à brillance élevée.
