Embodiment 1

[0029] Such as figure 1 Shown is an embodiment of a protective film composite cover plate according to the present invention, including a PET flexible plate 1, a 3D strengthened glass plate 2, the bent shapes of the PET flexible plate 1 and the 3D strengthened glass plate 2 are consistent, and the PET flexible plate 1 is bonded together with the 3D strengthened glass plate 2 by AB glue, and the side of the PET flexible plate 1 in contact with the AB glue is provided with a silk screen ink layer.

[0030] Further, in this embodiment, the thickness of the 3D strengthened glass plate is 0.2 mm.

[0031] The manufacturing method of the present embodiment comprises the following steps:

[0032] (1) Grinding the glass after CNC to obtain 3D glass, thinning the 3D glass to 0.2mm, strengthening and edge polishing to obtain a 3D strengthened glass plate;

[0033] (2) Cut and age the PET material at 90°C for 35 minutes to obtain a PET plate, and then cut and shape one side of the PET...

Embodiment 2

[0036] The difference from Example 1 is that: in step (2), the temperature of PET cutting and aging is 100°C, and the time of cutting and aging is 30 minutes; in step (3), the temperature of extrusion is 190°C, and the bonding pressure It is 1073N, the temperature for defoaming is 60°C, and the time for defoaming is 20 minutes.

Embodiment 3

[0038] The difference from Example 1 is that: in step (2), the temperature of PET cutting and aging is 80°C, and the time of cutting and aging is 40 minutes; in step (3), the temperature of extrusion is 175°C, and the bonding pressure The temperature is 1080N, the temperature for defoaming is 75°C, and the time for defoaming is 40 minutes.

Abstract

The invention provides a protection film composite cover plate which comprises a PET (polyethylene terephthalate) flexible plate and a 3D (three dimensional) tempered glass plate, wherein the PET flexible plate and the 3D tempered glass plate has the same bent shape; the PET flexible plate is bonded with the 3D tempered glass plate through AB glue; and a screen printing ink layer is arranged on the one side, contacted with the AB glue, of the PET flexible plate. The invention further provides a manufacturing method of the protection film composite cover plate. The protection film composite cover plate can achieve curved surface printing.

Description

technical field [0001] The invention relates to a protective film composite cover plate and a manufacturing method thereof. Background technique [0002] Most of the existing protective film cover plates are glass cover plates. The printing technology consists of glass and ink. The ink is screen printed on the back of the glass through the silk screen printing process. The process is as follows: image 3 shown. [0003] The glass cover plate has the advantages of high transmittance, scratch resistance, pressure resistance, drop resistance, and impact resistance, but there are also some disadvantages: [0004] Due to the high hardness and poor elasticity of glass, for some cover plates with special requirements (such as curved surface printing / concave surface around), the products printed by glass cover plate art have uneven color, uncontrollable precision, relatively large tolerance, and low yield. , unable to meet the needs of curved surface printing.
