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 field of film technology, and in particular relates to a colored explosion-proof film and a preparation method thereof. The colored explosion-proof film is composed of a PET film (1), a colored adhesive layer (2) and a release film (3). (1) The color explosion-proof film of the present invention provides color through the adhesive layer, without providing color for the mobile phone glass shell through the colored electroplating layer, which saves the color electroplating process, improves processing efficiency, and reduces processing difficulty; (2) through the adhesive layer Provide color, which solves the limitation of color selection in color electroplating, and can obtain a mobile phone shell with richer colors to attract consumers; (3) Adding a silane coupling agent to the coating liquid of the bonding layer can improve the adhesion on the one hand. The adhesion between the junction layer and the PET film and glass, on the other hand, helps to improve the dispersion uniformity of the pigment; (4) the color is provided through the bonding layer, and the artistic effect can be processed after heating to obtain the desired texture , matte effect, etc.

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...
