Description

Photothermal photochromic glass

Technical Field

The utility model relates to a glass technical field, in particular to color-changing glass.

Background

The existing building window glass, window glass and the like generally do not have the capacity of changing color according to illumination and temperature, and the color of the glass is fixed and unchangeable, so that the requirements of users cannot be well met. When the external light is strong, the user hopes that the glass can enhance the blocking of the external light; when the external light is weak, the user wants the glass to reduce the obstruction of the external light.

And the existing building window glass generally has no fireproof performance, once a building is in fire, the common glass can be rapidly broken at high temperature, and further the capability of blocking flames is lost.

In addition, the existing glass does not have the function of defogging, such as the glass for doors and windows of bathrooms and mirrors, the glass for vehicle windows and the like, and the like are easy to fog.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a light and heat photochromic glass to solve current ordinary glass and do not have the function according to external illumination and temperature discolour, do not have fire behavior, can not fine satisfy user's demand's technical problem.

The utility model discloses light and heat photochromic glass, including first layer glass, second floor glass and third layer glass, be provided with PVB photochromic film between first layer glass and the second floor glass, be provided with the fire prevention glue film between second floor glass and the third layer glass, second floor glass and third layer glass's the portion is provided with the sealing adhesive layer of rectangle frame form, the fire prevention glue film sets up in the sealing adhesive layer.

Furthermore, one side of the second layer of glass and one side of the third layer of glass, which are in contact with the fireproof glue layer, are frosted surfaces.

Furthermore, a U-shaped circuitous bent resistance heating wire is arranged in the third layer of glass.

The utility model has the advantages that:

1. the utility model discloses light and heat photochromic glass, because be provided with PVB color-changing membrane between first layer glass and the second floor glass, PVB color-changing membrane can change the colour under external environment illumination and temperature variation, under the strong circumstances of illumination, the glass colour can deepen to reduce the luminousness; under the condition of weakened illumination, the glass gradually becomes colorless and transparent. Consequently for current ordinary glass, the utility model discloses the user demand that satisfies that photothermal discoloration glass can be better. Furthermore, the utility model discloses light and heat photochromic glass still is provided with the fire prevention glue film, and when meeting with the conflagration condition, first layer glass and second floor glass can break because of the high temperature, and at this moment the fire prevention glue film can play thermal-insulated fire prevention's function, avoids high temperature and smog to transmit inwards.

2. The utility model discloses light and heat photochromic glass is provided with resistance heating wire in its third layer glass, when the fog condition appears in third layer glass, makes third layer glass intensifies to resistance heating wire circular telegram, can play the function to the defogging of third layer glass.

Detailed Description

The invention is further described with reference to the following figures and examples.

As shown in the figure, this embodiment light and heat allochroic glass includes first layer glass 1, second floor glass 2 and third layer glass 3, be provided with PVB allochroic membrane 4 between first layer glass and the second floor glass, be provided with fire prevention glue film 5 between second floor glass and the third layer glass, the portion of second floor glass and third layer glass is provided with rectangular frame's sealing glue layer 6, the setting of fire prevention glue film is in sealed glue film.

The PVB color-changing film is a polyvinyl butyral film which can change color under the change of illumination and temperature of the external environment. During production, the PVB color-changing film is covered on the first layer of glass, then the second layer of glass is covered on the PVB color-changing film, and then the first layer of glass, the PVB color-changing film and the second layer of glass are compounded into a whole at high temperature and high pressure. And then adhering a sealing adhesive layer 6 to the edge of the second layer of glass, reserving a section of glue injection hole on the sealing adhesive layer 6, adhering the third layer of glass to the sealing adhesive layer, injecting fireproof glue into the space in the sealing adhesive layer through the glue injection hole, and then baking the glass to cure the fireproof adhesive layer to obtain a finished product.

In the embodiment, the photochromic glass is installed, the first layer of glass faces outdoors, and the third layer of glass faces indoors. Due to the fact that the PVB color-changing film is arranged between the first layer of glass and the second layer of glass, the color of the PVB color-changing film can be changed under the illumination and temperature change of the external environment, and the color of the glass can be deepened under the strong illumination condition, so that the light transmittance is reduced; under the condition of weakened illumination, the glass gradually becomes colorless and transparent. Consequently for current ordinary glass, the utility model discloses the user demand that satisfies that photothermal discoloration glass can be better. Furthermore, the photochromic glass of this embodiment still is provided with the fire prevention glue film, and when meeting with the conflagration condition, first layer glass and second floor glass can be because of high temperature breaks, and at this moment the fire prevention glue film can play thermal-insulated fire prevention's function, avoids high temperature and smog to inwards transmit.

As the improvement to above-mentioned embodiment, the one side of being in contact with the fire prevention glue film on second glass and the third layer glass is the frosting, and this improvement makes can strengthen the joint strength of fire prevention glue film and second glass and third layer glass, and when second glass broke, the fire prevention glue film can be more reliable glues second glass piece, avoids it to drop.

As an improvement to the above embodiment, a resistance heating wire 7 bent in a U-shaped roundabout manner is arranged in the third layer of glass, the resistance heating wire is connected with a power plug 8, when the glass needs to be demisted, the power plug is connected with a power supply, so that the third layer of glass is heated, and water vapor can be prevented from condensing on the third layer of glass, thereby achieving a demisting effect. The resistance heating wire in the third layer of glass is pressed into the material of the third layer of glass in a molten state in the process of manufacturing the third layer of glass, and the resistance heating wire is contained in the third layer of glass after the third layer of glass is cooled and formed.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
