Definitions

  • the invention relates to a metallic-colored thermoplastic molding composition containing metal tinsel in different admixtures.
  • the invention relates to a method for producing this molding composition and the use of the molding composition according to the invention for the production of moldings.
  • Metallic-colored thermoplastic molding compounds are used, for example, where plastics have displaced metallic components, but for design reasons it is important to adapt the optical appearance of the molded bodies to the metallic structure of the previous metallic components.
  • this adaptation can be carried out in two ways: firstly by complex and cost-intensive subsequent color-coating of the molded parts or secondly by using a molding compound which already has the desired color effect. For economic and ecological reasons, the second way is preferable.
  • a disadvantage of the molding composition described there is that it tends to form visible flow lines when processed by injection molding, in particular when producing complicated molded parts with openings. These affect the uniform color impression and lead to poor quality molded part surfaces. This not only reduces the quality but also the usability of the molded parts produced.
  • the object of the invention is to provide a molding compound, when using this undesirable flow line formation does not occur, so as to improve the quality of the goods manufactured. It is also an object of the invention to provide a method with which molding compositions can be produced in which the end product produced therefrom is free of flow lines. Finally, it is an object of the invention to provide a shaped body with openings, the flow lines of which are invisible.
  • the mass fraction of the metal tinsel in the metallic-colored thermoplastic molding composition is greater than 5% and less than or equal to 15%.
  • the proportion by mass of the metal tufts in the metallic-colored molding composition is preferably more than 6%, in particular the proportion is between 6 and 13%.
  • the molding composition contains hexagonal metal tinsel.
  • the metal-tinsel admixture is advantageously any mixture of square, rectangular and hexagonal metal tinsel.
  • the shape of the metal tinsel is thus better adapted to the naturally occurring crystalline lattice structures.
  • these metal flakes are coated in order to intensify the bond to the base material and to improve the mechanical properties.
  • the object is also achieved in that in a particularly favorable
  • the generic molding compound contains a metal-tinsel admixture, the edge length distribution of which is not Gaussian-distributed.
  • the base material for the thermoplastic molding composition consists of polyamide, which preferably contains reinforcing materials, in particular fibers and / or fillers.
  • the process task for producing a metallic-colored thermoplastic molding composition is achieved in that the metal flakes are incorporated into the molding composition preferably by means of a screw extruder at a mixing point which has a ratio of screw length to diameter of more than 5 and less than 60 , preferably between 20 and 50, in particular 40.
  • the specific energy input that occurs during compounding of the molding compound is so limited that the admixing of the metal tinsel takes place non-destructively while maintaining the at least monomodal edge length distribution, and while maintaining complete mixing of base material and metal tinsel, which makes the end product appear free of flow lines.
  • thermoplastic molding composition according to the invention leads to the formation of a uniform surface of the molding in the production of complicated moldings, in particular those with openings. There are no visible flow lines.
  • a polyamide in particular ALCOM TM 6 PA 900/8 GF 10 MR 20 silver metallic 12-778 FF from the applicant, is preferably used as the base material.
  • the filler system consists of a 30% hybrid system. This granulate is melted in a twin-screw extruder in a known manner at the temperatures provided, with kneading and mixing zones also usually being provided in the twin-screw extruder.
  • the metal-tinsel admixture consists of various aluminum glitter, the edge length of the tinsel being between 100 and 200 ⁇ m and their thickness between 16 and 54 ⁇ m.
  • the metal flakes are only added in the direction of flow behind the kneading and mixing zones. The addition takes place at a mixing point which is at a ratio of screw length to diameter of 35.
  • the temperature of the screw extruder is between about 280 and 320 ° C in order to ensure the complete and homogeneous incorporation of the metal-tinsel addition.
  • the molding composition thus obtained is then cooled in a water bath and brought into the mold for later use, for example granulated.
  • This granulate is melted in an injection molding machine and injected through nozzles into a hollow mold which specifies the end product.
  • the molded body obtained after cooling has a uniform surface structure, flow lines do not appear visually, so they are invisible.

Abstract

L'invention concerne une matière moulable thermoplastique de couleur métallisée, qui contient des paillettes de métal en proportion variable, et un procédé pour fabriquer cette matière moulable, ainsi que son utilisation pour réaliser des corps moulés comportant des ouvertures. L'utilisation de cette matière moulable ne faisant pas ressortir de lignes d'écoulement visibles, elle permet d'améliorer la qualité des produits obtenus. A cet effet, le pourcentage en poids des paillettes de métal dans la matière moulable thermoplastique oscille entre six et 15 %, la dimension des paillettes ne répondant pas à une distribution gaussienne, mais la matière moulable contenant des paillettes de taille en grande partie seulement identique, également lorsqu'il s'agit de mélanges de paillettes.
