Embodiment 1

[0037] A composite reflective plate is prepared, and each layer is pasted with an adhesive, wherein the light-shielding layer is between the reflective layer and the reinforcing layer.

[0038] The anti-scratch layer is made of heat-cured polymethyl methacrylate, and the effective thickness of the coating is 1 micron, which is prepared on the opposite side of the reinforcement layer and the light-shielding layer.

Embodiment 2

[0040] A composite reflective plate is prepared, and each layer is pasted with an adhesive, wherein the light-shielding layer is between the reflective layer and the reinforcing layer.

[0041] The anti-scratch layer is made of UV-curable polymethyl methacrylate glue, and the effective thickness of the coating is 1 micron, which is prepared on the opposite side of the reinforcement layer and the light-shielding layer.

Embodiment 3

[0043] A composite reflective plate is prepared, and each layer is pasted with an adhesive, wherein the light-shielding layer is between the reflective layer and the reinforcing layer.

[0044] The anti-scratch layer is made of heat-cured polyethylene terephthalate glue, and the effective thickness of the coating is 1 micron, which is prepared on the opposite side of the reinforcement layer and the light-shielding layer.

Abstract

The invention provides a composite reflecting plate. The composite reflecting plate sequentially comprises a reflecting layer, a reinforcing layer, a shading layer and a scratch-resistant layer. The shading layer of the composite reflecting plate can be arranged between the reflecting layer and the reinforcing layer, and can also be arranged between the reinforcing layer and the scratch-resistantlayer. And the reflecting layer is selected from one of a polyester reflecting film, a polypropylene reflecting film, a polycarbonate reflecting film or a silver-plated reflecting film. And the reinforcing layer is made of one of glass, a plastic film or a plastic sheet. The shading layer is made of metal, nonmetal or alloy of metal and nonmetal. And the scratch-resistant layer is composed of oneof polyurethane formate (PU) glue, polyethylene glycol terephthalate (PET) glue and polymethyl methacrylate (PMMA) glue.

Description

technical field [0001] The invention belongs to the field of optoelectronic technology and relates to a composite reflector. Background technique [0002] At present, the needs of customers in the lighting and display fields are gradually becoming thinner and lighter, so side-type backlight modules are widely used, and the development direction for various components is also focused on simplification, integration, and light weight. In order to meet the market demand for side-entry backlight modules, our company has developed a composite reflector, which is used to integrate alternative reflective films and backplanes in side-entry backlight modules in lighting and display equipment. However, in the actual use of customers, it is found that due to handling and assembly reasons, the back of the composite reflector is easily scratched, and there will be obvious light leakage after scratches, resulting in poor assembly and seriously affecting the yield.
