Technical Field

[0001] This utility model relates to the field of light-shielding sheets, specifically a moisture-proof and heat-dissipating light-shielding sheet. Background Technology

[0002] A light-blocking plate, also known as a light-blocking plate, is an essential light-blocking element in fields such as cameras and mobile phone cameras. Its purpose is to prevent stray light from entering the viewfinder and affecting image quality. Light-blocking plates used in cameras are also called aperture stops, light-blocking rings, Mylar plates, etc. The thickness of such light-blocking plates is generally between 0.025mm and 0.012mm. Its central hole is a light-passing hole. In fact, light rays do not always maintain parallel illumination. Due to differences in intensity within the light rays, light rays will also cross. Therefore, the side walls of the central hole will always reflect the light, and some of it will further enter the viewfinder.

[0003] Existing light-shielding sheets are bonded to electronic devices with adhesive, which affects the dissipation of internal heat and can lead to overheating of the electronic devices. At the same time, electronic devices have high requirements for moisture protection and are easily damaged when exposed to moisture. Therefore, a moisture-proof and heat-dissipating light-shielding sheet is proposed to address the above problems. Utility Model Content

[0010] Preferably, the reinforcing layer includes a tensile layer, and a heat dissipation layer is provided on top of the tensile layer.

[0011] Preferably, the tensile layer is made of polypropylene and the heat dissipation layer is made of thermally conductive silicone.

By incorporating a heat-dissipating layer made of thermally conductive silicone, which has excellent flexibility and thermal conductivity, suitable for achieving heat dissipation in the light-shielding sheet, the heat dissipation performance of the light-shielding sheet body can be improved, preventing the light-shielding sheet from reducing the heat dissipation capacity of electronic devices after it is attached to them.

The light-shielding layer 2301 is made of light-shielding film material, and the insulating layer 2302 is made of polyvinyl chloride. By setting the light-shielding layer 2301 made of light-shielding film material, which is a special thin film material with high light-shielding performance, it can effectively block light from passing through, thereby improving the light-shielding performance of the light-shielding sheet body 2. By setting the insulating layer 2302 made of polyvinyl chloride, which is a common insulating material with good electrical insulation performance and weather resistance, it is suitable for making light-shielding sheets that require good insulation, thereby improving the insulation performance of the light-shielding sheet body 2.
