The invention discloses a starry sky roof film. The starry sky roof film is characterized by comprising the following layers which are stacked in sequence: a release protective film layer as a first layer, a first pressure-sensitive adhesive layer as a second layer, a second pressure-sensitive adhesive layer as a fourth layer, a second original film layer as a fifth layer, a third pressure-sensitive adhesive layer as a sixth layer, a photosensitive ink printing layer as a seventh layer, a light guide plate layer used as an eighth layer and made of a PE light guide plate, a fourth pressure-sensitive adhesive layer with the thickness of 3-200 microns as a ninth layer, a third original film layer as a tenth layer, a scratch-resistant layer as a eleventh layer, and a silica gel protective filmlayer with the thickness of 23-300 microns as a twelfth layer for enhancing the protective effect. Compared with the prior art, the preparation method of the starry sky roof film has the beneficial effects that the process is simple, the maximum thickness of the 12-layer film system structure and the pressure-sensitive adhesive layer reaches 150 microns, the stretchability of the starry sky rooffilm is increased, the flexibility is enhanced, the starry sky roof film can be tightly attached to an automobile front windshield, and broken glass can be firmly attached to the film when impacted byexternal foreign matter.
一种星空车顶膜,其特征在于:所述的星空车顶膜包括依次层叠的以下各层:第一层:离型保护膜层;第二次:第一压敏胶层;第四层:第二压敏胶层;第五层:第二原膜层;第六层:第三压敏胶层;第七层:感光油墨印刷层;第八层:导光板层,且导光板的材质为PE导光板;第九层:第四压敏胶层,其厚度为3~200μm;第十层:第三原膜层;第十一层:耐刮层;第十二层:硅胶保护膜层,23~300μm,增强保护作用。本发明的有益效果:与现有技术相比,本发明提供的星空车顶膜制备方法工艺简单,12层的膜系结构加上压敏胶层最厚达到150μm,使其拉伸性变大,柔韧性加强,可与汽车前挡玻璃紧密贴合,在受到外界异物冲击时,破碎的玻璃能被牢牢粘在膜上。
