Embodiment
The invention provides a kind of inner wall heat-preservation coating, comprise the component of following weight part:
The water of 5 parts ~ 45 parts;
The auxiliary agent of 3 parts ~ 25 parts;

Infrared reflecting paint, doped semiconductor and metallic cover cenosphere that the specific refractory power of 1 part ~ 30 parts is more than 2.0, particle diameter is not less than 1 μ m.
In the present invention, the infrared reflecting paint that specific refractory power is more than 2.0, particle diameter is not less than 1 μ m can be reflected back the mid and far infrared line thermal radiation of indoor exhausted vast scale indoor, has improved indoor heat insulation effect; Described doped semiconductor makes metope have lower thermal radiation absorption and high heat storage coefficient, the body of wall surface temperature is raise, thereby increased room temp, has greatly improved the hot comfort in room, has further improved indoor heat insulation effect; Described metal microbead by metallic cover after infrared reflectance be improved, emittance reduces, and has certain heat reflection effect; And have the structure of hollow due to the metallic cover cenosphere, thermal conductivity is little, has significantly promoted the obstructing capacity of heat insulation coating centering Far infra-red hot ray, has further improved indoor heat insulation effect.Therefore inner wall heat-preservation coating provided by the invention has higher heat insulation effect.
It is as follows that inner wall heat-preservation coating provided by the invention can improve the theoretical analysis of indoor heat insulating effect:
By the Wien shifting theorem as can be known, the peak wavelength λ that the radiation object is corresponding
mAnd have the relation shown in formula (I) between absolute temperature T:
λ
mT=2898（μm·K）?（I）
Wherein, λ
mWavelength for the object radiation ray; T is thermodynamic temperature;
Be that object temperature is higher, the peak wavelength λ of reflected radiation
mMore to short wave mobile.
According to different areas heating difference, room temp generally maintains between approximately 18 ℃ ~ 25 ℃, and indoor heating equipment top temperature is about 80 ℃, and its radiation peak is at 8.21 μ m; The object proximity room temperature of indoor lesser temps is got 18 ℃ of calculating of the minimum room temperature of national requirements winter heating, and its radiation peak is at 9.96 μ m; Human body temperature is about 37 ℃, and its radiation peak is at 9.35 μ m; And the visible light sources such as thermal source that indoor natural light is advanced as light source, TV light source, outdoor biography in indoor other invisible heats sources are less to indoor heat effects, can ignore.Through above analysis as can be known, indoor thermal radiation is originated and is comprised visible light, near infrared ray, far infrared rays, its cover heating radiation wavelength scope is 0.38 μ m ~ 14 μ m, but the Indoor Thermal ray mainly concentrates on the far infrared band of 6 μ m ~ 12 μ m, and reach more than 80% in the transmitance of this wave band invisible heat to room air, can directly pass through the interior space, reach inner wall surface.Therefore interior wall reflective thermal-insulating coating is coated on the interior wall internal surface, if can have higher reflectivity to the far infrared band that indoor 6 μ m ~ 12 μ m thermal radiation are concentrated, thereby just can promote the indoor reflection insulated capacity, prevent that indoor heat energy from passing wall and being diffused into outdoor;
According to Maxwell's Electromagnetic theory, ionogen is to having the relation shown in formula (II) between electromagnetic reflectivity:
ρ=（n-1）
2/(n+1)
2?（II）
Wherein: ρ is that ionogen is to electromagnetic reflectivity; N is electrolytical specific refractory power, and coating mineral filler major part used belongs to ionogen.By formula (II) as can be known, the specific refractory power of mineral filler is higher, and is higher to electromagnetic reflectivity, and heat insulation effect is better;
And the particle diameter of mineral filler and scattering wavelength X to have be the relation shown in (III):

(1) total radiation emittance increases along with the increase of temperature;
(2) peak wavelength of spectral radiant exitance is along with the increase of temperature is moved to the short direction of wavelength;
(3) spectral radiant exitance of perfect black body is only relevant with absolute temperature.
(IV) can find out by formula, and the surface emissivity degree of general object is except outside the Pass having with temperature, and is also relevant with emissivity.According to the kirchhoff rule, at a certain temperature, the radiant ratio of object is identical with specific absorption, and the different objects receptivity is different.
When invisible heat arrives low radiation inner wall heat-preservation coating surface, only produce reflection and absorb (in only being transmitted in transparent substance) two kinds of effects at surface of wall, if wall and surface has low thermal radiation absorption and high heat storage coefficient, the body of wall surface temperature is raise; The body of wall temperature raises, and also increases room temp simultaneously, has greatly improved the hot comfort in room, has improved indoor heat insulation effect.
