insulation barrier
1.FTIR, thermal conductivity device and smart digital rounding temperature testing device are used to test the infrared absorption spectrum, thermal conductivity and temperature changes of the title coatings, It is concluded that when hudrotalcite and magnesium sulfate is mixed by 4 to 10, the heat insulation property is the best, and the temperature changes of Nizi increased by 5℃ approximately compared with those without hydrotalcite and magnesium sulfate compound system, but the heat conduction coefficient is hardly increased because of the different mechanism of heat insulation of the fillers, which further prove that heat insulation with fillers is based on Infrared barrier.
