The object of the present invention is to provide an extrusion molding article
having an appearance resembling to natural timbers, and a method for producing
the same. The molded article of resins by an extrusion molding is produced as
follows: The glazed portion comprising at least a glazed face is produced with
a resin material containing wood powder in which the resin is blended with the
wood powder. The resin material containing wood powder comprises 20 to 40
parts of the wood powder having a particle size of 20 meshes or less and 0.5
to 4 parts of a blowing agent in 100 parts of a thermoplastic resin. The
glazed face is formed by removing skin layers formed during the extrusion
molding.
L'invention concerne la production d'un article moulé par extrusion ayant un aspect ressemblant à celui du bois naturel, ainsi qu'un procédé permettant de produire ledit article. On produit l'article moulé constitué de résines par un procédé de moulage par extrusion de la manière suivante: on produit la partie lustrée, présentant au moins une face lustrée, à partir d'un matériau à base de résine contenant de la poudre de bois, dans lequel la résine est mélangée à la poudre de bois. Le matériau à base de résine contenant de la poudre de bois renferme entre 20 et 40 parties de poudre de bois ayant un calibre de 20 mesh ou moins, et entre 0,5 et 4 parties d'un agent d'expansion pour 100 parties de résine thermoplastique. On forme la face lustrée en enlevant les couches de peaux formées durant le moulage par extrusion.
