Title
(EN) POLYMER RESIN COMPOSITION AND METHOD OF PREPARING THE SAME
(FR) COMPOSITION DE RESINE POLYMERE ET PROCEDE DE PREPARATION DE CETTE COMPOSITION
Abstract
(EN)
Provided are a polymer resin composition and a method of preparing the same. The polymer resin composition includes: a polymer resin; 0.01 -10.0 parts by weight of flaky pigment particles having an aspect ratio of 0.01-0.1 based on 100 parts by weight of the polymer resin; and 0.01 -10.0 parts by weight of polyhedral pigment particles having an aspect ratio of 0.300-0.999 based on 100 parts by weight of the polymer resin. Using the polymer resin composition, a polymer resin molded product having excellent appearance, i.e., having a uniform color even in resin flow lines or resin weld lines, and in which there is no degradation in the physical properties of the polymer resin contained therein can be manufactured at a low cost.

L'invention concerne une composition de résine polymère et un procédé de préparation de cette composition. La composition de résine polymère comprend une résine polymère, entre 0,01 et 10,0 parties en poids de particules de pigment lamellaire présentant un rapport de forme compris entre 0,01 et 0,1 sur la base de 100 parties en poids de la résine polymère, et entre 0,01 et 10 parties en poids de particules de pigment polyèdre présentant un rapport de forme compris entre 0,300 et 0,999 sur la base de 100 parties en poids de la résine polymère. Cette résine polymère permet de fabriquer, à moindres frais, un produit moulé de résine polymère présentant un excellent aspect, et notamment une couleur uniforme, y compris dans les lignes d'écoulement de résine ou les lignes de soudure de résine, les propriétés physiques de la résine polymère y contenue ne subissant aucune dégradation.
