The glass is transparent and bright, can create beautiful visual effect, and makes the building have the advantages of luxury, beautiful appearance, light weight, good lighting and the like, so that the glass is favored by architects, and is particularly widely applied to public buildings. But compared with other building envelopes, the glass has the worst thermal performance and is a weak link for building heat preservation and insulation. The energy consumption of an air conditioner of a common single-layer glass window accounts for more than 50 percent of the energy consumption of heating in winter or cooling in summer of a building.
In most of the conventional light-shielding type glasses, a light-shielding grid is provided in an interlayer of the glass, and light shielding is realized by lifting the light-shielding grid or rotating blades. However, the built-in light-shielding grille increases the width of the gap between the glasses, thereby making the glass structure thicker as a whole. And the shading grating is positioned in the glass interlayer, the structure is complex, and the shading grating is extremely difficult to maintain or replace if the shading grating is clamped or damaged when being pulled.

In order to achieve the above purpose, the present invention provides the following technical solutions:
the light-shading laminated glass comprises a first layer of glass and a second layer of glass, wherein the first layer of glass and the second layer of glass are arranged in parallel; a first intermediate film is arranged on the top end face of the first layer of glass, and a second intermediate film is arranged on the bottom end face of the second layer of glass; a PU layer is arranged between the first intermediate film and the second intermediate film, and a temperature-sensing color-changing intermediate film is arranged between the PU layer and the first intermediate film; the PU layer is internally provided with a heating wire, and the outer surface of the heating wire is provided with a silver coating.
Furthermore, the electric heating wire is in a filament shape and is arranged in an S shape, and connecting terminals are arranged at two ends of the electric heating wire and are positioned on the side surfaces of the first layer of glass and the second layer of glass.
Furthermore, the PU layer completely covers the electric heating wire, and the electric heating wire is specifically positioned on one side of the PU layer close to the thermochromic intermediate membrane.
Further, the first intermediate film is specifically a PVB intermediate film; the second intermediate film is specifically a PET intermediate film.
The invention has the beneficial effects that: the utility model provides a shading type laminated glass, through first intermediate coat, the temperature sensing intermediate coat that discolours, the PU layer, the cooperation of heating wire and second intermediate coat is used, adopt the temperature sensing to discolour the intermediate coat and replace the shading grid and realize the shading, and set up the heating wire temperature regulation and then realize the change of the luminousness of the temperature sensing intermediate coat that discolours, reach holistic shading effect, can obviously reduce the whole thickness of glass structure, be convenient for transport or installation, compare in mechanical structure's shading grid simultaneously, the fault rate of heating wire and temperature sensing discolour the intermediate coat is extremely low, therefore life is longer.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 and 2, the light-shielding laminated glass comprises a first layer of glass 1 and a second layer of glass 2, wherein the first layer of glass 1 and the second layer of glass 2 are arranged in parallel; a first intermediate film 3 is arranged on the top end face of the first layer of glass 1, and a second intermediate film 7 is arranged on the bottom end face of the second layer of glass 2; a PU layer 5 is arranged between the first intermediate film 3 and the second intermediate film 7, a temperature-sensitive color-changing intermediate film 4 is arranged between the PU layer 5 and the first intermediate film 3, and the color of the temperature-sensitive color-changing intermediate film 4 can change with the temperature; the inside heating wire 6 that is provided with of PU layer 5, heating wire 6 is used for the circular telegram to generate heat to play the control effect to the colour of temperature sensing intermediate coat 4 that discolours, the surface of heating wire 6 is provided with the silvered film, and the silvered film encircles 6 surfaces of heating wire, thereby the accessible reflection of light realizes the shielding of heating wire 6 on visual effect, and then avoids heating wire 6 to influence visual effect, and the silvered film has certain heat preservation effect, can maintain the temperature in a period after the outage, thereby plays energy-conserving effect.
The heating wire 6 is specifically in a filament shape and is arranged in an S shape, the two ends of the heating wire 6 are provided with the wiring terminals 8, the wiring terminals 8 are located on the side faces of the first layer of glass 1 and the second layer of glass 2, and the wiring terminals 8 are used for being connected with an external power supply line, so that power supply of the heating wire 6 is achieved.
The PU layer 5 completely coats the heating wire 6, and the heating wire 6 is specifically positioned on one side of the PU layer 5 close to the temperature sensing color changing intermediate film 4, so that the temperature generated by the heating wire 6 can be more quickly transferred to the temperature sensing color changing intermediate film 4.
The first intermediate film 3 is specifically a PVB intermediate film; the second intermediate film 7 is specifically a PET intermediate film.
The thermochromic intermediate film 4 is made of thermochromic low-melting-point polyester, and is a mature technology in the prior art.
The working principle of the invention is as follows: the first intermediate film 3, the PU layer 5 and the second intermediate film 7 are colorless and transparent; the electric heating wire 6 is a superfine resistance wire, and the surface is subjected to silver plating operation; after the silver plating operation is finished, the outer surface of the electric heating wire 6 is completely wrapped by the silver plating layer; because the silver coating has the light reflecting characteristic, the heating wire 6 can not be directly seen in the laminated glass, namely, the visual effect can not be reduced because the heating wire 6 is obviously seen. The temperature sensing color changing intermediate film 4 is light color transparent, and the temperature sensing color changing intermediate film 4 is light color under the condition of low temperature or normal temperature, so that the light can not be shielded; when light is required to be shielded, power is supplied to the wiring terminal 8 to form a loop, the heating wire 6 is electrified to generate heat, the heat is directly transmitted to the PU layer 5 through the silver coating layer and is uniformly transmitted to the temperature sensing color changing intermediate film 4 through the PU layer 5, the temperature sensing color changing intermediate film 4 starts to change color after being heated and gradually changes into dark color, and therefore blocking of a certain degree is formed for the light, and the shading effect is achieved.
