In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings obtained from these drawings still belong to the scope of the present invention without inventive laboriousness.
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
In the figure, 1, a PET protective layer; 2, a black electrostatic film; 3, a white electrostatic film; 4, an adhesive layer; and 5, printing the layer.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the black-white composite electrostatic film includes a black electrostatic film 2 and a white electrostatic film 3. The black electrostatic film which is completely lightproof is adopted, the best shading effect can be realized, however, the color printing is carried out on the black electrostatic film, the oil film is sprayed to form patterns or characters, the black substrate can influence the color developing effect of the color ink, therefore, the white electrostatic film is compounded on the surface of the black electrostatic film, the problem that the color printing cannot be carried out on the black electrostatic film is solved, and the electrostatic film which can shade the light and is attractive can be obtained by carrying out the color printing on the surface of the white electrostatic film.
The electrostatic protection film is characterized by further comprising a PET protection layer 1, wherein the PET protection layer 1, the black electrostatic film 2 and the white electrostatic film 3 are sequentially arranged. The PET protective layer 1 plays a role of protection when the black electrostatic film 2 and the white electrostatic film 3 are combined. The inventor finds that the problem of curling can occur when the black electrostatic film 2 and the white electrostatic film 3 are directly compounded under high-temperature hot pressing, and the rewinding is difficult to smoothly rewind in the subsequent rewinding process. Therefore, the inventor conducts further experiments to find that the PET protective layer 1 is firstly compounded with the black electrostatic film 2 and then compounded with the white electrostatic film 3, so that the compounding effect of the black electrostatic film 2 and the white electrostatic film 3 is better, and the problem of difficult rewinding is avoided.
The PET electrostatic protection film comprises a PET protection layer 1, a black electrostatic film 2, a white electrostatic film 3 and a printing layer 5 which are sequentially arranged.
An adhesive layer 4 is arranged between the black electrostatic film 2 and the white electrostatic film 3.
The adhesive layer 4 is formed by hot melt adhesive.
The preparation process of the black-white composite electrostatic film is as follows:
(1) compounding the PET protective film and the black electrostatic film at high temperature;
(2) uniformly coating a hot melt adhesive on the surface of the black electrostatic film far away from the PET protective film, and cooling to solidify the hot melt adhesive;
(3) one side of the black electrostatic film hot melt adhesive faces to the white electrostatic film, and the electrostatic films on the two sides are compounded under the high-temperature film pressure;
(4) printing ink on the surface of the white electrostatic film to form a printing layer;
(5) and (6) rewinding.
Through the preparation process, different series of products such as color printing, 2D and 3D which can shade light and are attractive can be developed, and the window sticker is suitable for being used as a window sticker with shading requirements and attractive requirements.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
