Novel anti-static projection writing panel and manufacturing method thereof

Abstract

The invention discloses a novel anti-static projection writing panel which comprises a substrate, a light source refraction layer, a reflection layer, an anti-static shading layer and an anti-static spraying layer. The anti-static spraying layer is arranged on one side of the substrate, the light source refraction layer is arranged on the other side of the substrate, the reflection layer is arranged on the side, away from the substrate, of the light source refraction layer, and the anti-static shading layer is arranged on the side, away from the light source refraction layer, of the reflectionlayer. The two sides of the novel anti-static projection writing panel are coated with the anti-static spraying layer and the anti-static shading layer respectively, so that the surface hardness, wear resistance and antistatic performance of the writing panel can be effectively enhanced. Due to the manufacturing material of the writing panel, the writing panel is high in plasticity. The manufacturing process of the writing panel is simple, the manufacturing cost is low, the material can be recycled and reused, and the writing panel meets the requirements of low-carbon economy, energy conservation and environmental protection and can be applied to various occasions.

Description

technical field [0001] The invention relates to the fields of projection boards and writing boards, in particular to a novel antistatic projection writing board and a manufacturing method thereof. Background technique [0002] The commonly used projection screens on the market at home and abroad are commonly known as "anti-light curtains", which are mainly formed by rolling paint on a layer of thin film plastic diaphragm, also known as the black grid process, also known as the Fresnel process. This process is currently widely used at home and abroad, and the technology is mature. Its disadvantages are as follows: [0003] 1. Due to its structural design, the anti-fouling performance of the board surface is poor, and ink pens cannot be used to write. The surface of the soft curtain cannot use ink due to the material and paint; [0004] 2. Due to the reason of its production material, after the layout is rubbed and contacted, it is easy to generate static electricity, which n...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to its structural design, the anti-fouling performance of the board surface is poor, and ink pens cannot be used to write. The surface of the soft curtain cannot use ink due to the material and paint;

[0004] 2. Due to the reason of its production material, after the layout is rubbed and contacted, it is easy to generate static electricity, which not only interferes with the capacitor circuit in the board, but also forms a large amount of dust layer on the board area;

[0005] 3. The surface hardness is not high, and the wear resistance is poor;

[0006] 4. The shape of soft curtain is not strong in shaping;

[0007] 5. The process is complicated, the manufacturing cost is high, and the scope of application is limited
