Referring to fig. 1 to 2, the present invention provides a light energy-saving wall structure based on aerogel heat insulation putty, which includes a wall base layer 110 and a waterproof finish layer 140, wherein the light energy-saving wall structure further includes an aerogel layer 130 connected between the wall base layer 110 and the waterproof finish layer 140.

The attachment of the aerogel putty layer 130 between the wall base layer 110 and the waterproof finish layer 140 means that the aerogel putty layer 130 is directly or indirectly attached to the wall base layer 110 and the waterproof finish layer 140, respectively, as will be understood below with respect to the attachment of layers and the attachment of a layer between layers.

In the scheme of this application, owing to connected aerogel layer 130 between wall body basic unit 110 and waterproof finish paint layer 140, aerogel layer 130 can realize the thermal insulation of air well, and aerogel density is extremely low, and present lightest aerogel only has 0.16 milligrams per cubic centimeter, slightly hangs down than air density, and aerogel layer about 2 millimeters just can satisfy the heat preservation requirement of building. Compared with the traditional putty layer, the wall body not only can play a role in heat insulation, but also can reduce or eliminate the phenomena of wall surface cracking and falling caused by expansion with heat and contraction with cold, and the whole wall body cannot become thick and heavy.

Wherein, aerogel layer 130 of the application forms based on the spraying of aerogel adiabatic putty, and its main component is silica aerogel, for further promoting its waterproof performance and heat-proof quality, can participate in the material of following parts by weight: 15-25 parts of emulsion for construction, 10-20 parts of fiber for construction and 10-20 parts of water repellent. The water repellent has the main functions of adding a waterproof film to the system, blocking a gap invisible to naked eyes by using the waterproof film and effectively improving the cost performance of the engineering application of the building heat insulation material. And the simple meeting of traditional technique adopts the outer wall to mix waterproof powder, but has not solved the fundamental problem, and one square of present outer wall insulation construction is according to the standard requirement and is beaten 12 crab-bolts, causes the outer wall sore hundred holes on the contrary, and outer wall infiltration aggravation. The water repellent cannot damage the external wall, and mainly comprises the following raw materials: acrylic acid glue powder, hydrophobic powder, dry powder defoamer, waterproof emulsion and the like.

It should be noted that aerogel is a solid substance, and the density of the solid substance is the lowest in the world. The density was 3kg per cubic meter. Because of the extremely low density, the lightest aerogels at present have only 0.16 milligrams per cubic centimeter, which is slightly less dense than air, and are also known as "frozen smoke" or "blue smoke". The new material seems fragile and durable and can bear the high temperature of 1400 ℃. Since the particles inside are very small (on the order of nanometers), visible light is scattered less through it (rayleigh scattering) as sunlight passes through the air. As the aerogel is generally more than 80 percent of air, the aerogel has very good heat insulation effect, and one inch of thick aerogel has the heat insulation function equivalent to that of 20 to 30 pieces of common glass. Even if the aerogel is placed between the roses and the flame, the roses can be damaged at all, and the scheme uses the aviation material in the field of building energy conservation and can play a very good role in heat insulation.

The waterproof primer layer 120 is made of waterproof paint, and the waterproof primer can prevent the insulating layer from cracking due to moisture caused by moisture seepage of the building concrete body. The waterproof topcoat layer 140 may be a topcoat variety that increases hardness and gloss.

As a specific embodiment of the present invention, the thickness of the aerogel layer 130 is 2 to 4 mm; the thickness of the waterproof finish paint layer 140 is 1 to 3 mm; the thickness of the waterproof primer layer 120 is 0.2 to 0.4 mm; the thickness of the anti-smudge reflective overcoat 150 is 0.2 to 0.4 millimeters.
