Abstract
(EN)
The present invention relates to a method for preparing an oriented polymer paint by using waste polyethylene terephthalate, and an oriented polymer paint prepared by the method and, more specifically, the method comprises the steps of: pulverizing waste PET into flaky particles; washing the pulverized flaky particles; preparing fractured microparticles from the washed flaky particles; mixing the prepared fractured microparticles with a functionalizing agent and a penetrant, and reacting same at 30-150°C for 10 minutes to 24 hours, thereby preparing functional fractured microparticles; and preparing a paint by mixing the prepared functional fractured microparticles and a vehicle. According to the method for preparing an oriented polymer paint by using waste PET, and an oriented polymer paint prepared by the method, of the present invention, the orientation structure of a PET container is horizontally moved to a paint without damage so as to enable the preparation of a paint having better performance than when using a new PET material, thereby having an advantage of forming high economical added-value having a new concept of recycling materials and performance.

La présente invention concerne un procédé de préparation d'une peinture à polymère orienté à l'aide de déchets de polyéthylène téréphtalate, et une peinture à polymère orientée préparée par le procédé et, plus spécifiquement, le procédé comprend les étapes consistant à : pulvériser des déchets de PET en particules floconneuses ; laver les particules floconneuses pulvérisées ; préparer des microparticules fracturées à partir des particules floconneuses lavées ; mélanger les microparticules fracturées préparées avec un agent de fonctionnalisation et un agent pénétrant, et les faire réagir à 30-150 °C pendant 10 minutes à 24 heures, ce qui permet de préparer des microparticules fracturées fonctionnelles ; et préparer une peinture par mélange des microparticules fracturées fonctionnelles préparées et d'un véhicule. Selon le procédé de préparation d'une peinture à polymère orientée à l'aide de déchets de PET, et une peinture à polymère orientée préparée par le procédé de la présente invention, la structure d'orientation d'un récipient en PET est déplacée horizontalement vers une peinture sans endommagement de manière à permettre la préparation d'une peinture ayant de meilleures performances que lors de l'utilisation d'un nouveau matériau en PET, ce qui a pour avantage de former une valeur ajoutée économique élevée ayant un nouveau concept de recyclage de matériaux et de performances.
