折射率

The effects of emulsions, pigments, conventional fillers, heat-insulation fillers and film thickness on the reflection and heat-insulation properties under infrared lamp are investigated in order to find the best materials for the heat-insulation coatings. It is found that both the titanium dioxide with high refractive index and the diatomite powder with micro pores possess the optimal reflection and heat-insulation properties, calcium carbonate also has sonic heat-insulation effect. However, the filler such as meerschaum, which in theory possesses the effect, has not shown heat-insulation function.
