Description
Technical field
The present invention relates to the lagging material technical field, relate in particular to a kind of inner wall heat-preservation coating.
Background technology
The heating system that present China generally adopts is mainly the radiator convected heating pattern, and such as floor heating, radiator etc., the panel type heating systems such as infrared electrothermal film are because heat distribution is more even, and are higher to human body and other object heat effect efficient, progressively popularize.Indoor heat conduction pattern is mainly radiation and convection current, no matter adopt convection heating or radiant heating, thermal radiation occupies critical role in indoor heat effect, can will be absorbed by body of wall when thermal radiation arrives surface of wall, thereby run off to outdoor.
The winter heating energy consumption is the main energy consumption of Chinese architecture, and Chinese Government improves constantly the requirement of building energy conservation.Fair in order to embody with heat, break away from the central heating of inefficiency and be accustomed to, all implemented the energy-conservation way of household-based heat metering for the reducing energy consumption project of new building and existing building.But, present building energy conservation heat insulation measure is only for the peripheral structure of building, generally do not adopt Insulation between the house partition wall in the building, may be different temperature like this between the different buildings, thereby generation hot pressing, the heat loss phenomenon can appear in the room that temperature is high, and namely heat flows to the low room of temperature from the high room of temperature.This unjust phenomenon with heat causes variety of issue and contradiction easily, more serious such as the heat loss in the resident family, so that uneven with heat between the neighbours, cause inequitable phenomenon, and have higher building energy consumption, thereby affected the popularization of China's Building Energy Conservation Policy.

Embodiment
The invention provides a kind of inner wall heat-preservation coating, comprise the component of following weight part:
5 parts ~ 45 parts water;
3 parts ~ 25 parts auxiliary agent;
3 parts ~ 55 parts mineral filler;
5 parts ~ 55 parts coating resin;
1 part ~ 30 parts metallic cover cenosphere and metal-powder.
Inner wall heat-preservation coating provided by the invention comprises metallic cover cenosphere and metal-powder, and the cenosphere infrared reflectance after the metallic cover is improved, and emittance reduces, and has certain heat reflection effect; And because the metallic cover cenosphere has the structure of hollow, thermal conductivity is little, therefore in the inner wall heat-preservation coating that obtains without the convection current air, reduced the thermal conductivity of coating, significantly promote the obstructing capacity of heat insulation coating centering Far infra-red hot ray, thereby improved indoor heat insulation effect; This described metal-powder can reflect the mid and far infrared line than the highland, thus the mid and far infrared line that indoor heating equipment, household electrical appliance and human body etc. are sent absolutely vast scale be reflected back indoor; And because continuity and the instantaneity of heat energy emission, the heat energy overwhelming majority of the inner wall heat-preservation coating Surface absorption that the present invention improves is returned again indoor by opticofacial winking reflex, thereby has improved indoor 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:
After body of wall has absorbed indoor invisible heat, produce the conversion of heat energy, the body of wall internal surface temperature can raise.The rising of body of wall temperature can produce 2 kinds of effects: the one, and passing to outdoor heat by body of wall increases, and is that metope is to the radiating capacity increase of the interior space more on the one hand.
What of Indoor Thermal loss these two kinds of net effects that occur in inner wall surface determine.Minimizing is transmitted to outdoor heat and can improves indoor heat insulation effect, the metallic cover cenosphere that the present invention adopts has hollow structure, and thermal conductivity is little, introduces without the convection current air in lagging material, improve the thermal resistance performance of coating, stoped the indoor wall heat outwards to scatter and disappear;
The cenosphere that the present invention adopts is through metallic cover, behind the cenosphere surface clad, can improve the electric conductivity of material, thereby improve it to the reflecting properties of ir radiation, reduction is to the absorption of ir radiation, referring to Fig. 1, Fig. 1 is the infrared emittance comparison curves before and after the cenosphere that adopts of the present invention coats, wherein curve a is the infrared emittance of cenosphere before the metallic cover, curve b is the infrared emittance of the metallic cover cenosphere that obtains after the metallic cover, as seen from Figure 1, infrared reflectance behind the cenosphere clad metal has reduced 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 is externally scattering and disappearing of trap heat on the one hand, increases on the one hand the heat reflection of centering far infrared rays, most reflect heat is returned indoor, thereby improved indoor heat insulation effect.Referring to Fig. 2, Fig. 2 is the illumination heating curve that the present invention adopts the cenosphere of different metal coating, wherein curve a, b and c are respectively the illumination heating curve that adopts the metallic cover cenosphere that obtains after gold and silver and the aluminium coating, as seen from Figure 2, the metallic cover cenosphere of the present invention's employing can improve room temp.
