Abstract
The invention relates to a reflective thermal-insulation paint which successively includes a putty layer, an undercoat layer and a finishing coat layer, wherein the putty layer is 1-3 cm in thickness, the undercoat layer is 20-40 [mu]m in thickness and the finishing coat layer is 90-110 [mu]m in thickness. By means of the reflective insulation paint, a coating layer, which is high in reflective rate, is high in radiation rate and is low in thermal-conductive rate, can be obtained mainly through control of a solar energy reflective rate, an infrared radiation rate and a thermal-conductive rate of a material. Visible lights and infrared light in sunlight are reflected due to the high reflective rate of the material and meanwhile absorbed energy is dissipated in a manner of thermal-radiation by means of the high radiation rate of the material so that a surface-layer temperature of the material is reduced and heat transmitted into an internal environment is reduced. Meanwhile, by means of the low thermal-conductive rate of the coating layer, heat is further insulated from being transmitted into the internal environment so that the temperature of the internal environment is maximumly maintained, thereby achieving an object of insulating heat and maintaining temperature. The reflective insulation paint not only is good in thermal-insulation effect but also is environmental-protective and toxic-free.
Description
Technical field
The present invention relates to paint field is and in particular to a kind of exterior wall reflective thermal insulation coating for building.
Background technology
With developing rapidly of China's building trade and becoming increasingly conspicuous of energy crisis, the energy-saving of building is got over
Send out important.The building energy consumption of China accounts for the 27% of national energy aggregate consumption, occupies first of national all kinds of energy consumption.Heating and air-conditioning
Energy consumption account for the 55% of building total energy consumption, but also increased with annual 1 percentage point of speed.Because a bit, research and development is built
Build insulating moulding coating and there is great economic benefit, environmental benefit and social benefit.Use in external wall and there is heat insulating function
Coating not only can realize the original decoration of coating, protection and the function such as mould proof, but also makes coating have heat-insulated function, protects
Hold that indoor temperature is constant, increase the temperature difference of indoor and outdoor, reduce warm energy consumption in summer, reduce heat cost in the winter time.At present, heat-insulated
Material just experiencing from industry heat-insulated to the transformation based on heat-insulating, this be also heat-barrier material from now on main development direction it
One.Insulating moulding coating in the market has the disadvantage that：1st, heat-proof quality is poor, and the heat-proof quality of insulating moulding coating needs further
Raising；2nd, adopt solvent based coating, unfavorable for environmental protection；3rd, the reflection filler price being used for preparing reflection type thermal insulation coating is general
All over very high, cause it relatively costly.
Content of the invention
The heat-proof quality that the present invention solves insulating moulding coating in prior art is poor, for unfavorable, the relatively costly skill of environmental protection
Art problem, is to provide a kind of reduces cost on the premise of improving its heat-proof quality, and the effect of energy-conserving and environment-protective simultaneously
Reflective heat-insulation paint.
The concrete technical scheme that the present invention adopts is as follows：
A kind of reflective heat-insulation paint, includes putty layer, prime coat and top coat layer, the thickness of described putty layer is 1 successively
3cm, the thickness of prime coat is 20 40um, and the thickness of top coat layer is 90 110um；
Described top coat layer is counted by weight including following material：
Described priming paint is counted by weight including following material：
Above-mentioned top coat layer also includes 18 21 parts of titanium dioxide.
Preferably described top coat layer is counted by weight including following material：
Described prime coat is counted by weight including following material：
Described microbicide solution is 1 by bactericide and water in mass ratio:0.5 1.5 compositions.
