Technical field
The present invention relates to technical field of coatings, particularly a kind of freeze proof radiation heat insulation coating and preparation method thereof.
Background technology
Along with developing rapidly of China's building trade and becoming increasingly conspicuous of energy dilemma, saving energy and reduce the cost of buildings is just important all the more.The building energy consumption of China accounts for 27% of national energy aggregate consumption, occupies first of national all kinds of energy consumption.The energy consumption of heating and air-conditioning accounts for 55% of building total energy consumption, but also is increasing with the speed of annual 1 percentage point.Because of a little, research and development insulating mold coating for construction has great economic benefit, environmental benefit and social benefit.Use the coating with heat insulating function not only can realize the functions such as the original decoration of coating, protection and mildew-resistant at external wall; but also making coating have heat insulation function, homo(io)thermism in holding chamber, increases the temperature difference of indoor and outdoor; reduce warm energy consumption in summer, reduce heat cost in the winter time.
Thermal insulating coating is the thermal accumlation being reduced coated article inside by mechanism such as obstruct, reflection, radiation, thus reaches energy-conservation a kind of functional coating with improving the object such as Working environment or safety.General thermal insulating coating is divided into isolation-type, reflection-type and Radiation Heat-insulated Paint three class.Wherein, Radiation Heat-insulated Paint is by transferring the UV-light in the sun power absorbed, visible ray and near infrared luminous energy to heat energy, in 8-13. 5 mu m waveband, pass air infrared window in the mode of ir radiation, be transmitted into air skin efficiently, thus reach the object reducing temperature.The distinguishing feature that Radiation Heat-insulated Paint is different from other two classes thermal insulating coatings is: all the other two class thermal insulating coatings can only slow down but can not the transmission of block heat, and Radiation Heat-insulated Paint can fall with the heat radiation of the form of heat emission by absorption, thus impel that coating is inside and outside lowers the temperature with same speed.
There is following shortcoming in the thermal insulating coating of current use: throughout the year by solar ultraviolet effect, paint aging; Winter temperature is too low, causes powdering of paint, produces grinning effect.The result of these question synthesis effects above, will make that the effect of heat insulation of paint film is deteriorated, work-ing life shortens.
