Description
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of colour reflective insulating moulding coating and preparation thereof,
Construction method.
Background technology
At present China's town building area about 16,000,000,000, heating with can consume about 1.5 hundred million tons mark coals/
Year, be equivalent to the 16%～18% of China's non-power generating coal, along with urbanization process rate improve constantly and
The improvement of people's lives condition, also will increase 100～15,000,000,000 newly to the year two thousand twenty China town building,
Increments is that the 65%～90% of construction area is built up in current city.This will cause the continuous increasing of energy for building
Long, cause the immense pressure to China's energy supply system.The building energy conservation potentiality of China are very big, build
Building energy-conservation has become an instant task, country using building energy conservation as an important base
This state basic policy.The history of China's power conservation requirement experienced by drilling from energy-conservation 30%, 50%, 65% three phases
Enter, but the implementation result of the target of country's execution power conservation requirement second stage energy-conservation 50% be unsatisfactory,
Many provinces and cities the most not yet reach the target of first stage.
Building thermal-insulating coating belongs to Functional Architectural Coatings in China, refers to be coated on body surface, to heat spoke
The near infrared band (0.72-2.5 μm) hit has high reflectance, and by the heat energy of absorption with long wave
The form of (2.5-15 μm) is radiated outer space, thus suppression is hot in the case of not consumed energy
Amount is by coating and the propagation of metope, to keep the energy-saving functional coating material of indoor temperature.
According to conduction, convection current and three kinds of heat transfer mechanism of radiation, thermal insulation coatings substantially can be divided into obstruct
Type, radial pattern and reflection type thermal insulation coating 3 class.The insulation mechanism of this 3 class heat insulating coatings is not
With, application scenario and obtained effect are the most different.
A. isolation-type thermal insulation coatings
The Insulating mechanism of isolation-type thermal insulation coatings is to stop heat transfer, is come by the high thermal resistance of coating self
Realize insulation, be belonging to thick film coating.It is coated with during coating application and dresses up certain thickness, generally 5～20mm,
After abundant dry solidification, owing to after material drying and forming-film, thermal conductivity is the least, it is generally less than
0.06W/ (m K), therefore coating has certain ability reducing hot-fluid transmission.So at heat insulation material
Introducing the thermal conductivity factor that can significantly reduce material without convected air in material, this is to obtain good heat insulation effect
The theoretical foundation of fruit.Hollow glass micropearl, ceramic fine bead, the filler such as resin microsphere all has hollow
Structure, thermal conductivity factor is less, has a wide range of applications in intercepting thermal insulation coatings.
Current most widely used isolation-type thermal insulation coatings is silicates composite coating, and this kind of coating is
The class novel heat insulation material that late 1980s grows up.You Shangbaijia research unit of China
Carrying out the research work of this kind of coating with enterprise, the name of product of each manufacturer is not quite similar, as
" composite aluminium-magnesium-silicate insulating moulding coating ", " rare-earth thermal insulating coating ", " application type composition silicate every
Hot coating " etc., formulation for coating material, construction method are different, and its performance such as quick-drying speed is hard, waterproof, hydrophobic
Deng the most different, but all belong to silicate coating.There is own material structure band in present this kind of coating
Come defect, as length arid cycle, construction is big by season and climatic effect, impact resistance is weak, do
Dry contraction is big, hydroscopicity is big, to the adhesion strength of body of wall is on the low side and dicoration remains to be further improved
Deng, therefore this kind of coating is the most less for exterior wall application.
B. reflection-type thermal insulation coatings
Reflection-type building thermal-insulating coating, its general principle is that the reflex by film additive is by red
External radiation reflects back, and reduces building self and causes the rising of building enclosure temperature to produce because absorbing radiation
Heat consumes.Visible, only it is improved the reflectivity of coating, coating surface just can be made to absorb less
Energy.Reflection-type building thermal-insulating coating utilizes film to make to be radiated film to the high reflex of light and heat
On most of energy reflected rather than absorbed by film, thus effectively reduce building in temperature
Degree rises.
The sun reflectivity of reflection-type building coating is by the material of coating, film coated surface flatness, light
Cleanliness, color and determined by factors such as thermal wavelengths.Coating thickness is anti-to the sun in limited range
Penetrating and affect than, once reach optimal reflecting effect, being further added by coating thickness also will not increase coating
Sun reflectivity.This point is closely related with coating thickness with the insulation effect of isolation-type adiabatic coating
Principle be diverse.
C. radial pattern thermal insulation coatings
The mechanism of action of radial pattern building thermal-insulating coating is that the form by radiation is building surface heat
The heat of radiation is launched with certain wavelength, blocks the heat energy transmission to indoor, decreases and build
The heat absorption built, thus reach the effect of good heat preservation energy-saving.
