DETAILED DESCRIPTION
[0020] 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.
[0021] See also Figure 1-4 The utility model provides an embodiment: an electromagnetically adjustable color-changing glass, comprising an outer frame 1, a color-changing glass body 2, the color-changing glass body 2 is composed of a polymer liquid crystal layer 3, an adhesive layer body 4, an outer glass 5, and a transparent conductive film 6, the front and rear ends of the polymer liquid crystal layer 3 are fixed with a transparent conductive film 6, one end of the transparent conductive film 6 is fixed with an adhesive layer body 4, one end of the adhesive layer body 4 is fixed with an outer glass 5, and the outer side wall of the outer glass 5 is fixed with an anti-scratch film.
[0022] The transparent conductive film 6 is symmetrically distributed with respect to the central axis of the polymer liquid crystal layer 3 , and the outer glass 5 is symmetrically distributed with respect to the central axis of the polymer liquid crystal layer 3 .
[0023] The adhesive layer body 4 is composed of a heat-insulating adhesive layer 7, a first fixed adhesive layer 8, and a second fixed adhesive layer 9. The second fixed adhesive layer 9 is fixed to the bottom end of the first fixed adhesive layer 8, and the heat-insulating adhesive layer 7 is fixed to the top end of the first fixed adhesive layer 8 and the bottom end of the second fixed adhesive layer 9.
[0024] The coating surface areas of the first fixing adhesive layer 8 and the second fixing adhesive layer 9 are the same, and the coating surface area of the heat insulating adhesive layer 7 is the same as that of the first fixing adhesive layer 8 or the second fixing adhesive layer 9 .
[0025] A flame retardant plate 10 is fixed inside the outer frame 1 , a positioning block 11 is installed at one end of the flame retardant plate 10 , an arc groove 13 is opened inside the positioning block 11 , and a fixed airbag block 12 is installed inside the arc groove 13 .
[0026] The positioning blocks 11 are evenly distributed at one end of the flame retardant plate 10, and a flame retardant adhesive layer is fixed to the inner wall of the arc groove 13, and the flame retardant adhesive layer and the fixed airbag block 12 are fixed to each other;
[0027] Furthermore, the fixed airbag block 12 is filled with flame retardant powder, which may be magnesium oxide powder. Under normal circumstances, the magnesium oxide powder is sealed inside the fixed airbag block 12. When a fire or the like occurs, when the fixed airbag block 12 is damaged by heat, the magnesium oxide powder exists stably at high temperatures and decomposes to release a large amount of water and carbon dioxide, thereby playing a flame retardant role.
[0028] Furthermore, the polymer liquid crystal layer 3 is based on PDLC technology and has the dual properties of liquid crystal and polymer. When voltage is applied, the liquid crystal molecules in the PDLC film will rearrange, making the glass transparent. In the power-off state, the liquid crystal molecules will be arranged in a disordered manner, causing the glass to become opaque, thereby forming a color-changing operation.
[0029] Working principle: First, fix the anti-scratch film on the outside of the outer glass 5 for protection, and then form the adhesive layer body 4 by combining the heat-insulating adhesive layer 7, the first fixed adhesive layer 8 and the second fixed adhesive layer 9. The adhesive layer body 4 is used for bonding and fixing. With the addition of the heat-insulating adhesive layer 7, part of the heat generated when power is turned on is isolated to ensure the bonding and fixing effect of the first fixed adhesive layer 8 and the second fixed adhesive layer 9 after bonding. When working, the polymer liquid crystal layer 3, the adhesive layer body 4, the outer glass 5 and the transparent conductive film 6 are combined to form the whole of the color-changing glass body 2, and the adhesive layer body 4 is mainly used for bonding and fixing, and the position of the transparent conductive film 6 completes the power-on work. After the power-on work, the polymer in the polymer liquid crystal layer 3 forms an oxidation-reduction reaction, so that the transparency of the outer glass 5 changes. After the power is turned off, the outer glass 5 forms a fogged anti-peeping state, and after the power is turned on, it can quickly form a transparent state.
