[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1-Figure 3As shown, a thin light-enhancing plate with high adaptability includes a main body 1, characterized in that a triangular prism is provided on one side of the main body 1, and the lower side of the main body 1 is set to a smooth surface, an adhesive 2 is coated on the horizontal surface of the main body 1, and the thickness of the adhesive 2 is set to one-fourth of the thickness of the main body 1, and a separation film 3 is provided on the other side of the adhesive 2 at the end away from the main body 1, and the thickness of the separation film 3 is the same as the thickness of the adhesive 2, and the area of ​​the separation film 3 is the same as the area of ​​the main body 1. When the adhesive 2 is applied, it is first applied to the smooth surface of the main body 1, and after it is laid flat on the main body 1, the separation film 3 is covered on the adhesive 2, the adhesive 2 is chloroprene rubber, and the adhesive 2 is specifically set to anionic chloroprene rubber, the model of the adhesive 2 is SNL-511A, and the separation film 3 is set to an upper and lower part, and the separation film 3 is close to the main body 1. The side close to the adhesive 2 is a PVA coated high-barrier plastic film, and the material of the separating film 3 is specifically set to a polyvinyl alcohol high-barrier composite film, the upper half of the separating film 3 is set to a grid paper, and the separating film 3 needs to be coated with the polyvinyl alcohol high-barrier composite film on the grid paper during preparation. Before using the main body 1, it is first necessary to draw a drawing on the grid paper according to specific installation requirements, and then use a ruler, a knife back or other sheet with a higher hardness to scratch the separating film 3 along the drawing. In this way, the grid paper can be damaged so that the operator can more directly observe whether the scratch is offset, and as the scratching is carried out, the adhesive 2 can be squeezed to both sides through the PVA coated high-barrier plastic film, and finally the main body 1 can be cut according to the scratch, and the separating film 3 can be peeled off during installation, and the main body 1 can be pasted at the specified position.

[0018] Furthermore, the separation film 3 squeezes the adhesive 2 toward both sides, which can prevent the adhesive 2 from adhering to the cutting knife during cutting, and can also press down one side of the separation film 3 to prevent the remaining adhesive 2 from being directly exposed to the air, thereby extending the service life of the device.

[0019] Furthermore, a grid paper is provided on one side of the separation film 3 to assist in drawing and improve the convenience of drawing.

[0020] Furthermore, the material of the separation film 3 near the adhesive 2 is set to be a polyvinyl alcohol high-barrier composite film because the material has good ductility and toughness, which can prevent the separation film 3 from rupturing prematurely when scratching.

[0021] Furthermore, the material of the adhesive 2 is set to chloroprene rubber because the material has physical and mechanical properties, and has the advantages of oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance, and chemical reagent resistance, thereby ensuring the adhesion effect while extending the service life of the device.

[0022] Working principle: When using this thin and highly adaptable light-enhancing board, first, before using the main body 1, you need to draw a drawing on the grid paper according to the specific installation requirements, and then use a ruler, knife back or other sheet-like objects with high hardness to scratch the separation film 3 along the drawing, so that the grid paper can be damaged so that the operator can more directly observe whether the scratch is offset, and as the scratch is made, the adhesive 2 can be squeezed to both sides through the PVA-coated high-barrier plastic film, and finally the main body 1 can be cut according to the scratch, and the separation film 3 can be peeled off during installation, and the main body 1 can be pasted in the specified position. This is the working principle of this thin and highly adaptable light-enhancing board.
