Detailed description of the invention
The invention provides a kind of inner wall heat-preservation coating, including the component of following weight portion:
The water of 5 parts ~ 45 parts；
The auxiliary agent of 3 parts ~ 25 parts；
The inorganic filler of 3 parts ~ 55 parts；

Inner wall heat-preservation coating provided by the invention includes doped semiconductor and metal dust, and described doped semiconductor makes metope have relatively low thermal radiation absorption and high heat storage coefficient, and body of wall surface temperature can be made to raise；Body of wall temperature raises, and also increases indoor temperature simultaneously, substantially increases the hot comfort in room, improves the heat insulation effect of indoor；Metal dust can reflect mid and far infrared line higher, therefore, when adopting inner wall heat-preservation coating provided by the invention, the mid and far infrared line that indoor heating equipment, household electrical appliance and human body etc. send can absolutely vast scale be reflected back indoor；Being additionally, since seriality and instantaneity that heat energy is launched, the heat energy overwhelming majority of the inner wall heat-preservation coating Surface absorption that the present invention improves is gone back to indoor by opticofacial winking reflex again, thus improve the heat insulation effect of indoor.Therefore, inner wall heat-preservation coating provided by the invention has higher indoor heat insulating effect.
The theory analysis that inner wall heat-preservation coating provided by the invention can improve indoor heat insulating effect is as follows:
The object that nature exists, absorbing while sunlight also constantly outwardly radiating invisible infrared light and the longer electromagnetic wave of wavelength, is referred to as heat radiation.This radiation is to be caused by the warm-up movement of molecule, atom, and emittance size is closely related with temperature and body surface character.The radiancy of general object is derived according to Planck law, and radiant intensity has the expression formula shown in formula (I):
M=εσT4(I)
Wherein: ε is radiance, σ is Boltzmann constant, and T is thermodynamic temperature；
The spectral radiant exitance of the black matrix of different thermodynamic temperatures is different, and black body radiation emittance has characteristics that
(1) total radiation emittance increases along with the increase of temperature；
(2) peak wavelength of spectral radiant exitance, along with the increase of temperature is moved to the direction that wavelength is short；
(3) spectral radiant exitance of absolute black body is only relevant with absolute temperature.
By formula (I) it can be seen that the surface emissivity degree of general object is except outside the Pass having with temperature, also relevant with emissivity.According to kirchhoff rule, at a certain temperature, the radiance of object is identical with absorbance, and different objects absorbability is different.
When heat ray arrives Low emissivity inner wall heat-preservation coating surface, only produce reflection at surface of wall and absorb (through being only transmitted in transparent substance) two kinds of effects, if wall and surface has low thermal radiation absorption and high heat storage coefficient, body of wall surface temperature can be made to raise；Body of wall temperature raises, and also increases indoor temperature simultaneously, substantially increases the hot comfort in room, improves the heat insulation effect of indoor.
Present invention research shows, doped semiconductor one class material has certain carrier concentration, its 5 μm ~ 15 mu m waveband can be made to have higher infrared reflectivity and low infrared emittance, can be used for preparing interior wall reflective thermal-insulating coating, to improve indoor heat insulating effect, such as tin-antiomony oxide (ATO), referring to Fig. 1, Fig. 1 is the graph of a relation of the ATO reflectance that adopts of the present invention and reflection wavelength, wherein N represents carrier concentration, as seen from Figure 1, owing to doped semiconductor has certain carrier concentration, such that it is able to by adjusting the carrier concentration changing doped semiconductor, it is made to have higher infrared reflectivity and low infrared emittance at 5 μm ~ 15 mu m wavebands.
It addition, by Wien shifting theorem it can be seen that peak wavelength λ corresponding to radiating objectmAnd there is between absolute temperature T the relation shown in formula (II):
λmT=2898(μm of K) (II)
