Outside, additionally it is possible to which reflected solar radiation is warm and reduces film coated surface temperature, and mitigates and brought because summer, film coated surface temperature was excessively high
A series of problems.Although there are many insulating moulding coating research for building, there is also problems in practical applications, such as：Property
Can it is unstable, patent 200510028388.7 report reflective heat-insulation paint although have fairly good solar reflectivity,
Infrared emittance is poor；Color is single, mainly based on white or light-colored coating, limitation is larger etc..
Common coating is easy to happen thermal degradation and carbonization under the high temperature conditions so that soil layer is destroyed, cannot be to base
Material plays a protective role, and high-temperature resistant coating can keep not embrittlement under the high temperature conditions, not with base material stripping, be not bubbled it is same
When keep certain physics and chemistry and mechanical performance so that object can be bad from chemical attack, oxidation corrosion etc. at high temperature
The influence of situation.It functions only as heat-blocking action to existing building insulating moulding coating, but for such as 400 DEG C of higher temperature its own
High temperature resistance it is poor, phenomena such as being susceptible to Paint Falling.Therefore, existing insulating moulding coating for building restricts it and is building
The application of energy-saving field.
