Title (EN) CURVED SURFACE PROTECTIVE FILM, COATING AND LAMINATING METHOD AND FORMING METHOD THEREFOR
(FR) FILM PROTECTEUR DE SURFACE INCURVÉE, PROCÉDÉ DE REVÊTEMENT ET DE STRATIFICATION ET SON PROCÉDÉ DE FORMATION
(ZH) 一种曲面保护膜及其涂布覆合方法和成型方法
Abstract:
(EN) A curved surface protective film, comprising a first PET release film (40), a first hardening layer (20), a base material layer (10), a second hardening layer (30), a silica gel layer (50), and a fluorinated organosilicone release layer (60) that are stacked sequentially from top to bottom. The first PET release film (40) comprises a PET release film body and a first adhesive layer disposed below the PET release film body. The curved surface protective film has high hardness and high stability after fitting a curved surface mobile phone, is capable of fitting a curved surface screen well, is durable and resistant to scratch, thereby providing a more stable, effective and comprehensive protection for the curved surface mobile phone screen, and is easy to apply, thereby providing good user experience. Also disclosed is a coating and laminating method for a curved surface protective film. The coating and laminating method has a simple process, few steps, and safe operation. Also disclosed is a forming method for a curved surface protective film. The forming method has a simple process, safe and simple operation, and low costs.
(FR) L'invention concerne un film protecteur de surface incurvée, comprenant une premier film anti-adhésif en PET (40), une première couche de durcissement (20), une couche de matériau de base (10), une seconde couche de durcissement (30), une couche de gel de silice (50), et une couche anti-adhésive d'organosilicone fluorée (60) qui sont empilées séquentiellement de haut en bas. Le premier film anti-adhésif en PET (40) comprend un corps de film anti-adhésif en PET et une première couche adhésive disposée au-dessous du corps de film anti-adhésif en PET. Le film protecteur de surface incurvée a une dureté élevée et une stabilité élevée après ajustement d'un téléphone mobile à surface incurvée, est apte à s'ajuster sur un puits d'écran à surface incurvé, est durable et résistant à la rayure, ce qui permet d'obtenir une protection plus stable, efficace et globale pour l'écran de téléphone mobile à surface incurvée, et est facile à appliquer, fournissant ainsi une bonne expérience d'utilisateur. L'invention concerne également un procédé de revêtement et de stratification destiné à un film protecteur de surface incurvée. Le procédé de revêtement et de stratification présente un processus simple, peu d'étapes et un fonctionnement sûr. L'invention concerne également un procédé de formation destiné à un film protecteur de surface incurvée. Le procédé de formation présente un processus simple, un fonctionnement sûr et simple, et des coûts faibles.
(ZH) 一种曲面保护膜,包括从上往下依次层叠的第一PET离型膜(40)、第一硬化层(20)、基材层(10)、第二硬化层(30)、硅胶层(50)和氟化有机硅离型层(60);其中,第一PET离型膜(40)包括PET离型膜本体,以及设置在PET离型膜本体下方的第一胶层。该曲面保护膜硬度大,贴合曲面手机后稳定性好,能够与曲面屏幕完美贴合,耐用耐刮,为曲面手机屏幕提供更稳定、有效以及全面的保护;并且容易贴膜,体验性好。还公开了一种曲面保护膜的涂布覆合方法,工艺简单,步骤少,操作安全。又公开了一种曲面保护膜的成型方法,工艺简单,操作安全简单,成本低。
