Description
Technical Field
The invention belongs to the technical field of transparent layers, and particularly relates to a tungsten bronze/silica gel heat-insulating functional material and a preparation method thereof.
Background
Along with the great increase of the building area in China, the problem of building energy consumption is more and more serious, and great pressure is caused on energy supply and ecological environment. At present, the building energy consumption of China accounts for about 30% of the total social energy consumption. Among these energy consumptions, heating energy consumption in the northern winter and air conditioning energy consumption in the southern summer account for a major part. The area of the door and window glass accounts for about 30% of the area of the peripheral structure of the building, the door and window glass is a main channel for exchanging energy between the building and the environment and is a main part causing energy consumption of the building, and the energy dissipation accounts for about 2/3 of the total energy consumption of the building. The transparent heat-insulating material can shield the radiation of near infrared light (wavelength range of 1000-2500nm) on the premise of keeping visible light collection and transparent vision, thereby reducing the intake of solar energy, effectively reducing the energy consumption of an air conditioner in summer, reducing the outward diffusion of indoor heat in winter and realizing the purpose of building energy conservation.
In recent years, research on blocking near infrared light by dispersing nanoparticles in a transparent coating has been greatly advanced, and application of the transparent coating to glass of buildings or automobiles can reduce energy consumption of air conditioners, thereby reducing emission of greenhouse gases. The traditional energy-saving window (electrochromic glass, gasochromic glass and the like) has a complex structure and sometimes needs energy input, and the transparent coating dispersed with the near-infrared isolation nano particles is relatively simple and has higher efficiency in the aspect of energy saving.
The near infrared shielding material generally refers to a kind of functional thin film material which has strong absorption or reflection of near infrared light without affecting the visible light transmission. The widely known near-infrared shielding nano materials include the following types: noble metals (Ag, Au, etc.), semiconductor oxides (ATO, ITO, etc.), rare earth hexaboride (LaB6, PrB6, NdB 6). The surface plasmon resonance enables the nano materials to have the property of shielding near infrared, but each of them has advantages and disadvantages: a film containing noble metal particles has a low transmittance in the visible light region; ATO and ITO are relatively stable and have high transmittance in a visible light region, but can only effectively shield near infrared light with the wavelength of more than 1500 nm; the hexaboride heat insulating material can only shield near infrared light with a certain wavelength, and the rare earth hexaboride has high hardness and must be ground in the preparation process.
Tungsten bronze (M)xWO3M is Na + or K+,Rb+,Cs+And NH4 +) As the most promising heat shielding material, it has been reported in recent years that it has a high visible light transmittance and can shield near infrared light having a wavelength of more than 1000nm, thereby having more excellent near infrared shielding performance. In the prior art, Chinese patent CN104528829A discloses a preparation method of cesium tungsten bronze powder; chinese patent CN104726040A discloses a preparation method of PVB slurry containing tungsten bronze; xiaoyong Wu et al (nanoscale.2015.7(40):17048-17054.) prepared novel CsxWO3The coating material for the/ZnO intelligent window not only has excellent heat-insulating property, but also can catalyze and decompose the air under the action of lightHarmful NO gas, but the process is relatively complex; in addition, Jingxiao Liu et al (Applied Surface science.2014.309: 175-.
