Problems solved by technology

[0004] However, when the above-mentioned dimming glass is used in an area with a large temperature difference between day and night, the glass surface is prone to condensation and fogging. After fogging, the glass surface is wet and easily absorbs dirt, which reduces the light transmission performance of the self-cleaning dimming glass. affect the indoor temperature

preparation example Construction

[0050] Preparation of nano-alumina inclusions: take 100 parts of polyborosiloxane and 50 parts of nano-alumina, melt 100 parts of polyborosiloxane at 200 ° C to form a molten liquid, use the molten liquid to wrap nano-alumina, and Low-temperature freezing at -40°C for 24 hours, after freezing at 300°C, N 2 The high temperature sintering is carried out in the environment, and the sintered body is crushed by a pulverizer.

[0051] Pretreatment of polytetrafluoroethylene powder: before feeding polytetrafluoroethylene powder, it needs to be moistened with ether, and the amount of ether should be controlled to be 3% of that of polytetrafluoroethylene powder.

Embodiment 1

[0053] A method for preparing self-cleaning temperature-regulating glass, comprising the steps of:

[0054] (1) Use a glass cleaner to remove the oil on the surface of the glass substrate, and dry it with a cloth; continue to wipe and degrease with a clean cotton cloth dipped in acetone to ensure that there is no oil and attachments on the glass surface;

[0055] (2) Spray a hydrophobic anti-fog layer on the outer surface of the glass substrate, wherein the hydrophobic anti-fog layer is formed by spraying a hydrophobic anti-fog paint;

[0056] (3) A heat-sensitive temperature-regulating layer is sprayed between the two glass substrates, and the heat-sensitive temperature-regulating layer is formed by spraying a heat-sensitive temperature-regulating paint;

[0057] (4) Align the two glass substrates in sequence, and then put the two glass substrates into an autoclave, control the temperature at 130~135°C, and press at 13~14Mpa for pressing.

[0058] Wherein the preparation pro...

Embodiment 2

[0068] Example 2: The difference from Example 1 is that the components of the hydrophobic anti-fog coating are different. Weigh 12 parts of acrylic acid, 12 parts of methyl acrylate, 10 parts of isooctyl acrylate, 12 parts of fluorine-containing acrylic resin, polytetrafluoroethylene 10~15 parts of vinyl fluoride powder, 1~3 parts of polyoxyethylene hydrogenated castor oil, 1~3 parts of sodium lauryl sulfate, 0.1~1 part of azobisisoheptanonitrile, 20~25 parts of water.

Abstract

The invention discloses self-cleaning thermoregulation glass and a preparation method thereof. The technical scheme key point includes two opposite glass substrates, the outer sides of the two glass substrates are each spray-coated with a hydrophobic antifogging layer, and a thermosensitive thermoregulation layer is spray-coated between the two glass substrates. In an area where the day-night temperature difference is large, the surfaces of the glass substrates are easy to fog, and the outer sides of the glass substrates are each spray-coated with the hydrophobic antifogging layer, the high and low temperature resistance and weatherability of the glass substrates are improved, and the hydrophobic antifogging layers have the advantages of hydrophobicity, oleophobicity, no adhesion and no stickiness; the outer sides of the glass substrates are not easy to fog, and moisture does not easily wet the surfaces, so the anti-dirt and anti-fouling properties of the glass substrates are improved;according to different levels of illumination intensity, the thermosensitive thermoregulation layer can control room temperature, and the hydrophobic antifogging layer and the thermosensitive thermoregulation layer are in mutual coordination effects, so the comprehensive use performance of the self-cleaning thermoregulation glass is improved.

Description

technical field [0001] The invention relates to building energy-saving glass and a manufacturing method thereof, in particular to a self-cleaning temperature-regulating glass and a manufacturing method thereof. Background technique [0002] Self-cleaning dimmable glass is a new type of special photoelectric glass product. The liquid crystal film is compounded into the middle of two layers of glass, and the sandwich structure is formed by high temperature and high pressure. There are several ways to switch between transparent and opaque states of glass. Self-cleaning dimming glass not only has all the characteristics of safety glass, but also has the privacy protection function of controlling whether the glass is transparent or not. [0003] At present, the Chinese patent with the authorized announcement number CN201540423U among the existing patents discloses a dimming glass. The dimming glass includes a sequentially laminated PDLC laminate, a first adhesive layer, and glas...
