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;
The mineral filler of 3 parts ~ 55 parts;
The coating resin of 5 parts ~ 55 parts;
The specific refractory power of 1 part ~ 30 parts is more than 2.0, particle diameter is not less than infrared reflecting paint, metallic cover cenosphere and the metal-powder of 1 μm.
In the present invention, specific refractory power is more than 2.0, particle diameter is not less than the infrared reflecting paint of 1 μm and the mid and far infrared line thermal radiation of exhausted for indoor vast scale all can be reflected back indoor by metal-powder, improves indoor heat insulation effect; Described metal microbead is improved by infrared reflectance after metallic cover, and emittance reduces, and has certain heat reflection effect; And there is the structure of hollow due to metallic cover cenosphere, thermal conductivity is little, significantly improves the obstructing capacity of heat insulation coating centering Far infra-red hot ray, further increasing indoor heat insulation effect.Therefore, inner wall heat-preservation coating provided by the invention has higher heat insulation effect.
The theoretical analysis that inner wall heat-preservation coating provided by the invention can improve indoor heat insulating effect is as follows:
From Wien shifting theorem, the peak wavelength λ that radiating object is corresponding
mand there is between absolute temperature T the relation shown in formula (I):
λ
mT=2898（μm·K）（I）
Wherein, λ
mfor the wavelength of object radiation ray; T is thermodynamic temperature;
Namely 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 about 18 DEG C ~ 25 DEG C, and indoor heating equipment top temperature is about 80 DEG C, and its radiation peak is at 8.21 μm; The object proximity room temperature of indoor lesser temps, get the 18 DEG C of calculating of the minimum room temperature of national requirements winter heating, its radiation peak is at 9.96 μm; Human body temperature is about 37 DEG C, and its radiation peak is at 9.35 μm; And indoor other invisible heats source as light source, TV light source, that outdoor passes the visible light sources such as the thermal source of the natural light into indoor is less to indoor heat effects, can ignore.Known through above analysis, indoor thermal radiation source comprises visible ray, near infrared ray, far infrared rays, its cover heating radiated wavelength range is 0.38 μm ~ 14 μm, but Indoor Thermal ray mainly concentrates on the far infrared band of 6 μm ~ 12 μm, and reach more than 80% in the transmitance of this wave band invisible heat to room air, directly can pass through the interior space, reach inner wall surface.Therefore interior wall reflective thermal-insulating coatings is at interior wall internal surface, if higher reflectivity can be had to the far infrared band that indoor 6 μm ~ 12 μm thermal radiation are concentrated, thus just can promote indoor reflection insulated capacity, prevent indoor heat energy to be diffused into outdoor through wall;
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.From formula (II), the specific refractory power of mineral filler is higher, 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):
λ=d/k
Wherein, k is constant, 4.4 × 10
-1.
Therefore, it is possible to there is the particle diameter of the material of higher reflectivity more than 1 μm to the far infrared band that indoor mid and far infrared thermal radiation is concentrated;
To sum up analyze, the present invention's research draws, specific refractory power more than 2.0, the infrared reflecting paint of particle diameter more than 1 μm and metal-powder all can reflect the indoor mid and far infrared line of the overwhelming majority, thus can improve the heat insulation effect of indoor;

These the two kinds of net effects occurring in inner wall surface determine Indoor Thermals loss number.Reduce and be transmitted to the heat insulation effect that outdoor heat can improve indoor, the metallic cover cenosphere that the present invention adopts has hollow structure, and thermal conductivity is little, introduces without convected air in lagging material, improve the thermal resistance performance of coating, stop indoor wall heat outwards to scatter and disappear;
The cenosphere that the present invention adopts is through metallic cover, after cenosphere surface clad, the electric conductivity of material can be improved, thus improve its reflecting properties to ir radiation, reduce the absorption to ir radiation, referring to Fig. 2, Fig. 2 is the infrared emittance comparison curves of the coated front and back of cenosphere that the present invention adopts, wherein curve a is the infrared emittance of cenosphere before metallic cover, curve b is the infrared emittance of the metallic cover cenosphere obtained after metallic cover, as seen from Figure 2, infrared reflectance after cenosphere clad metal reduces about 30%, therefore, in the present invention, the cenosphere of described metallic cover can increase the heat reflection to indoor mid and far infrared line,
Therefore, indoor heat insulating coating provided by the invention on the one hand the external of trap heat scatters and disappears, and increases the heat reflection of centering far infrared rays on the one hand, most reflect heat is gone back to indoor, thus improves the heat insulation effect to indoor.See Fig. 3, Fig. 3 is the illumination heating curve of the cenosphere that the present invention adopts different metal coated, wherein curve a, b and c be respectively adopt gold and silver and aluminium coated after the illumination heating curve of metallic cover cenosphere that obtains, as seen from Figure 3, the metallic cover cenosphere that the present invention adopts can improve room temp.
