Embodiment Construction

[0042] In order to explain the technical characteristics, purpose and effect of the present invention more clearly, the accompanying figure 1 , 2 , 3 illustrate the specific implementation method of the present invention.

[0043] The preparation method of the easy-to-stick type color-changing starry sky car roof film of the present invention is described in detail below:

[0044] 1. First, provide a PET release film layer. The PET release film is stretched under the condition of a tension of 300N without obvious deformation, and is used as the original film protection film layer 1;

[0045] 2. Provide a silicone protective film layer 12, whose peeling force is required to reach 15gf, so as to enhance the protective effect on the substrate;

[0046] 3. Provide the PE light guide plate layer 8, uniformly print the photosensitive ink printing layer 7 with the designed starry sky pattern on the light guide plate by a screen printing machine, then put it into the dryer, adjust t...

Abstract

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.

Description

technical field [0001] The invention relates to an easy-to-stick color-changing starry sky car roof film attached to the inner side of automobile sunroof glass, in particular to an easy-to-stick color-changing starry sky car roof film and a preparation method thereof. Background technique [0002] Nowadays, with the development of the economy and the progress of the society, there are more and more "car owners", and the age group is gradually becoming younger. Young people are pursuing the fashion sense of the car while pursuing the performance of the car. Therefore, the car star car The top membrane came out. Ordinary starry roof film on the market is highly ornamental, novel in design, safe and explosion-proof, and is widely loved by car owners. But at the same time of beauty, ordinary starry roof film also has a disadvantage-it is not easy to paste, and the construction is extremely difficult . [0003] There are two types of film sticking methods in the market: wet sti...
