Detailed Description
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to specific embodiments of the present utility model and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1
As shown in fig. 1, the cover plate with polarization function provided by the utility model comprises:
a first hardened layer 10; a polarizing layer 20 at least partially covering the first hardened layer 10; a first PMMA layer 30 at least partially covering the polarizing layer 20; a PC layer 40 at least partially covering the first PMMA layer 30; a second PMMA layer 50 at least partially covering the PC layer 40; the second stiffening layer 60 at least partially covers the second PMMA layer 50.
The PMMA/PC/PMMA composite board is used as the cover board, has high light transmittance, can replace glass, has hardness and toughness, can resist strong impact and is thinner as a whole; the polarizing layer 20 is added on the plate, so that the functionality of the cover plate is increased; the first hardening layer 10 and the second hardening layer 60 are respectively arranged on two sides of the PMMA/PC/PMMA composite board, so that the hardness of the cover plate is increased, and the friction damage of the external environment to the cover plate is effectively isolated.
In this embodiment, the first PMMA layer 30, the PC layer 40 and the second PMMA layer 50 are preferably provided to be formed by coextrusion. Co-extrusion refers to a plastic processing technology that two or more raw materials are processed at one time and molded at one time by an extruder. The material can effectively utilize the properties of various materials, improve the mechanical properties and the thermal properties of products, and has good processing performance and product properties. The coextrusion can realize the compounding of different materials, and can produce materials with good performance. PMMA is lighter than glass with the same size, and PC has toughness, and PMMA has higher hardness than PC, so that the PMMA/PC/PMMA composite board processed by the method has hardness and toughness, and is lighter than glass with the same size, so that the cover plate is lighter and thinner.
In this embodiment, the first PMMA layer 30 and the second PMMA layer 50 have the same thickness.
Further, the thickness of the PC layer 40 is 5 to 10 times that of the first PMMA layer 30 or the second PMMA layer 50. Preferably 8 times.

In this embodiment, the polarizing layer 20 is preferably a coated polarizing layer, which is cured by aligning anisotropic absorbing dye molecules. The arrangement of dye molecules can be realized by utilizing a photoalignment technology, and then utilizing the rotation effect of photoinduced molecules, so that the molecules rotate to be vertical to the polarization direction.
In a preferred embodiment, the second hardened layer 50 may also be covered with other functional layers, such as: an anti-fingerprint layer or an AR protective film layer. The design is carried out according to the actual situation, and is not limited herein.
