The invention provides an easy-to-stick color-changing starry sky roof film and a preparation method thereof. The preparation method comprises the following steps: printing a layer of photosensitive ink painting on a light guide plate through a screen printer, and immediately drying in a dryer to form a light guide plate layer; coating one side of the light guide plate layer with a layer of pressure-sensitive adhesive in a coating manner to form a third pressure-sensitive adhesive layer, and compounding a layer of original film to form a third original film layer; and coating the other side ofthe third original film layer with a scratch-resistant layer, and compounding a layer of silica gel protective film to form a silica gel protective film layer. Compared with the prior art, the preparation method of the easy-to-stick color-changing starry sky roof film provided by the invention has the beneficial effects that the process is simple, the total thickness reaches 40mil, and the 12-layer film system structure and the strong toughness of the silica gel self-sticking film layer enable the stretchability to be increased, the flexibility to be enhanced, and the easy-to-stick color-changing starry sky roof film can be tightly attached to automobile skylight glass; and when the glass is impacted by external foreign matters, the broken glass can be firmly adhered to the film and doesnot splash around, so that the safety explosion-proof performance is high.
一种易贴式变色星空车顶膜及其制备方法,通过丝网印刷机,在导光板上印一层感光油墨画,随即在烘干机内烘干,形成导光板层;在导光板层的一侧通过涂布方式涂布一层压敏胶,形成第三压敏胶层,并复合一层原膜,形成第三原膜层;在第三原膜层的另一侧涂布耐刮层,并复合一层硅胶保护膜,形成硅胶保护膜层;本发明的有益效果:与现有技术相比,本发明提供的易贴式变色星空车顶膜制备方法工艺简单,总厚度达到40mil、12层的膜系结构加上硅胶自贴膜层自带的强大韧性,使其拉伸性变大,柔韧性加强,可与汽车天窗玻璃紧密贴合,在受到外界异物冲击时,破碎的玻璃能被牢牢粘在膜上,不四处飞溅,安全防爆性能高。
