Preparation method for material, is mainly used for being effectively improved building enclosure environment, realizes energy-saving and emission-reduction, environmental protection.
Background technology
Heat-reflecting insulating coating refers to be applied over building surface have higher sun luminous reflectance and hemispherical emissivity,
The coating of heat-blocking action can be played, it can effectively reflect, obstruct, radiating the energy of sunlight, hence it is evident that reduce outside building
Wall, roof and indoor temperature, reduce the energy consumption of the refrigeration plants such as air-conditioning under the high temperature conditions, have not only improved working environment but also have saved
The about substantial amounts of energy.Therefore, the research and development of high-performance solar heat reflecting and heat insulating coating have grand strategy to building energy conservation
Meaning.
Reflective heat-insulation paint is made of base-material, heat reflection pigment, filler and auxiliary agent etc..By high-efficiency reflective sunlight come
Reach heat-insulated purpose.Reflective heat-insulation paint is collection reflection, radiates the new High tailored coating heat-insulated and integral with cenosphere, coating
High reflection can be carried out to the solar infrared and ultraviolet of 400-2500nm scopes, not allow the heat of the sun to be carried out in body surface
Accumulation heating, and heat heat loss through radiation cooling can be carried out automatically, the heat of body surface is radiated in space, reduces object
Temperature, even in cloudy day and night coating also can radiations heat energy reduce temperature, while it is extremely low to be put into coating thermal conductivity factor
Cenosphere isolation thermal energy transmission, when atmospheric temperature is very high also can every firmly outside heat to interior of articles conduct,
Three large effects ensure that the object cooling of brushing paint, it is ensured that interior of articles space can keep the state of lasting constant temperature.Reflection
For insulating moulding coating in sunlight strong, coating can reduce by more than 20 DEG C of body surface temperature, and cloudy day and night can cool down at 3 DEG C
Above or it is reduced to consistent with atmospheric temperature.Reflective heat-insulation paint has decoration and heat-insulated dual-use function, belongs to feature
Coating.High reflectivity insulating moulding coating is used on the surface of peripheral structure, absorption of the building to solar radiant heat can be reduced,
Prevent building surface temperature caused by absorbing solar radiation from raising, reduce heat and be passed to indoor.Mainly ground in the past
Study carefully and applied on roofing, to reduce temperature rising and shield to roof waterpoof material.In recent years due to Overseas New height
The appearance of efficiency reflecting material hollow glass bead and the distribution to commodity, have promoted this kind of coating in south China hot summer and warm winter zone
The application of regional wall face.Such coating is used cooperatively with outer wall heat preservation system, has higher energysaving effectiveness.
