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 [0001] The invention relates to the field of coatings, in particular to a reflective heat-insulating coating for exterior walls of buildings. Background technique [0002] With the rapid development of my country's construction industry and the increasingly prominent energy crisis, the energy saving and consumption reduction of buildings is becoming more and more important. my country's building energy consumption accounts for about 27% of the country's total energy consumption, ranking first in all types of energy consumption in the country. The energy consumption of heating and air conditioning accounts for 55% of the total energy consumption of buildings, and it is still increasing at a rate of 1% per year. Therefore, the research and development of building thermal insulation coatings has significant economic, environmental and social benefits. The use of coatings with heat insulation function on the exterior walls of buildings can not only realize the ...
