Title
(EN) COATING FILM FOR ATTACHMENT TO OUTER SURFACE OF AUTOMOBILE WINDSHIELD AND PREPARATION METHOD OF SAME

Abstract
(EN)
The present invention provides a coating film for attachment to the outer surface of an automobile windshield, wherein a functional coating layer serving as the outermost surface contains a polymer formed to have a chain structure by reacting 2-oxepanone polymer with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, and thus, when attached to the outer surface of the automobile windshield, can effectively protect the windshield from stone-chip damage. Also, the functional coating layer having anti-fouling, water-repellent, self-healing, and IR-blocking functions is formed of a soft material rather than of a UV-curable type material, thus minimizing the occurrence of scratches formed by windshield wipers, and even when a scratch is formed, the self-healing function causes the scratch to naturally disappear over time, thus securing an optimal field of view for a driver. In addition, the present invention relates to a preparation method of the coating film.

La présente invention concerne un film de revêtement destiné à être fixé à la surface extérieure d'un pare-brise d'automobile. Une couche de revêtement fonctionnelle constituant la surface la plus à l'extérieur contient un polymère conçu pour avoir une structure de chaîne par réaction d'un polymère de 2-oxépanone avec du 2-éthyl-2-(hydroxyméthyl)-1,3-propanediol. Ainsi, lorsqu'il est fixé à la surface extérieure du pare-brise d'automobile, le film de revêtement peut protéger efficacement le pare-brise contre des dommages causés par un éclat de pierre. En outre, la couche de revêtement fonctionnelle dotée de fonctions anti-encrassement, hydrofuges, d'autorégénération et de blocage des IR est constituée d'un matériau souple plutôt que d'un matériau de type durcissable aux UV, ce qui permet de réduire au minimum l'apparition de rayures provoquées par des essuie-glaces, et même en cas de formation de rayures, la fonction d'autoréparation entraîne la disparition naturelle de la rayure avec le temps, ce qui permet de garantir un champ de vision optimal pour un conducteur. De plus, la présente invention concerne un procédé de préparation du film de revêtement.

본 발명은, 최외표면이 되는 기능성 코팅층이, 2-옥사파논폴리머와 2-에틸-2-(하이드록시메틸)-1,3-프로판디올을 반응시켜 체인(chain) 형태의 구조를 갖도록 형성되는 폴리머(2-Oxepanone, polymer with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol)를 포함하여, 자동차 앞 유리의 바깥 면에 부착하여 스톤칩에 의한 앞 유리의 파손을 효과적으로 방지할 수 있고, 방오, 발수, 자가복원 및 IR차단 기능을 갖는 기능성 코팅층이 UV 경화 타입이 아닌 소프트 한 재질로 이루어져 와이퍼에 의한 스크래치 발생을 최소화하고 스크래치가 발생하더라도 자가 복원 기능에 의해 시간이 지나면서 자연적으로 제거되도록 하여 운전자의 시야를 최적으로 확보할 수 있는 자동차 앞 유리 바깥 면 부착용 코팅 필름 및 그 제조 방법을 제공한다.
