  • the experimental results show that the steps of the preparing process of the modified polyurethane coating have an effect to the crack resistance performance of the plastic bright bar having the modified polyurethane coating.
  • the modified polyurethane coating is prepared before the injection molding, which will further improve the crack resistance performance of the plastic bright bar having the modified polyurethane coating.
  • Embodiment 8 preparing glass window
  • the preparing process includes following steps:
  • (1) preparing of the modified polyurethane can refer to that of Embodiment 1.
  • Step 1 producing a piece of 3.85mm toughened glass (i.e., green glass) using a conventional KT (main component is polystyrene) line.
  • KT main component is polystyrene
  • Step 2 forming a bright bar by means of punching an aluminum plate, and implementing an anodizing treatment to a surface of the bright bar.
  • Step 3 uniformly applying the modified polyurethane prepared above to the surface of the bright bar by means of manual spraying.
  • Step 4 placing the bright bar prepared in Step 3 into a molding cavity of a window edge encapsulation injection mold reserved for the bright bar, and then placing the toughened glass prepared in Step 1 and other sub-components into corresponding positions of the molding cavity, respectively.
  • Step 5 injecting a PVC (polyvinyl chloride) material into the molding cavity at a conventional PVC injection temperature (e.g., 185 °C) , and removing the assembly from the mold after a holding time (e.g., 5-20 seconds) .

Abstract

La présente invention décrit une garniture extérieure, une vitre comprenant la garniture extérieure et un procédé de moulage par injection destiné à la formation d'une vitre. La garniture extérieure comprend : un substrat et un revêtement de polyuréthane modifié disposé sur une surface du substrat. La vitre comprend : une plaque en verre, la garniture extérieure précitée, et une encapsulation de tranche autour d'une tranche de la plaque en verre, la garniture extérieure étant fixée à la vitre par l'intermédiaire de l'encapsulation de tranche. Le procédé de moulage par injection destiné à la formation de la vitre comprend : la mise en place d'une plaque en verre et d'une garniture extérieure présentant un revêtement de polyuréthane modifié sur sa surface, lesquelles sont placées ensemble, dans un moule ; l'injection d'un matériau de moulage dans une cavité de moule ; et le refroidissement du matériau de moulage qui est moulé par injection pour former une encapsulation de tranche autour de la tranche de la plaque en verre.
