preparation example Construction

[0032] The preparation method of the colored explosion-proof film is as follows:

[0033] (1) Add acrylate, solvent, curing agent and colorant in sequence to the liquid mixing tank to prepare a coating solution with a solid content of 20-60%, stir for 10-60min, and then stand for 0.5-2h;

[0034] (2) Apply the prepared coating solution evenly on the surface of the PET film, and heat it at 60-140°C for 1-5min to obtain a colored adhesive layer;

[0035] (3) Attach the release film to the surface of the adhesive layer to ensure that there are no air bubbles in the attachment;

[0036] (4) curing the product prepared in step (3) at 40° C. for 2-4 days to obtain a colored explosion-proof film.

[0037] The parameters of Examples 1-5 are shown in Table 1.

[0038] Table 1

[0039]

[0040] Wherein, the color paste color is not limited to the several colors listed in Table 1, and various colors can be selected according to needs.

Embodiment 5

[0041] Example 5 After uniformly coating the prepared coating solution on the surface of the PET film in step (2), let it stand for 10 minutes before heating and subsequent treatment.

Abstract

The invention belongs to the technical field of films, and particularly relates to a color explosion-proof film and a preparation method thereof. The color explosion-proof film consists of a PET film(1), a color bonding layer (2) and a release film (3). (1) According to the color explosion-proof film, the color is provided through the bonding layer, the color is not required to be provided for aglass shell of a mobile phone through a color electroplating layer, a color electroplating process is omitted, the processing efficiency is improved, and the processing difficulty is reduced; (2) thecolor is provided through the bonding layer, limitation of color selection in color electroplating is solved, mobile phone shells with richer colors can be obtained, and consumers are attracted; (3) asilane coupling agent is added into coating liquid of the bonding layer, therefore, on the one hand, the adhesive force between the bonding layer and the PET film as well as the glass can be improved, and on the other hand, the dispersion uniformity of pigment can be improved; and (4) the color is provided through the bonding layer, and artistic effect processing can be implemented after heating,so that the required texture, sanding effect and the like are obtained.

Description

technical field [0001] The invention belongs to the technical field of membranes, and in particular relates to a colored explosion-proof membrane and a preparation method thereof. Background technique [0002] With the development of science and technology, digital products such as mobile phones and tablet computers have penetrated into thousands of households and become an indispensable part of Nissan's daily life. The shell material of smartphones has developed from the initial plastic shell to metal shell, glass shell, ceramic shell, etc. in the past two years. [0003] Plastic and metal are widely used due to the simple processing technology, but the glass casing has the advantage of high appearance and better signal than the metal casing, so it is widely used in the current high-end mobile phones. Glass also has the disadvantages of poor wear resistance and fragility. In order to strengthen the glass and prevent the glass from breaking and scattering and causing injury...
