and (3) testing the heat conductivity coefficient: and testing the heat conductivity coefficient of the coating by using a heat conductivity coefficient instrument.
Testing the heat insulation performance: selecting an aluminum-magnesium alloy plate with the thickness of 2mm, cleaning and completely drying the square with the size of 20cm multiplied by 20cm, coating the surface of the aluminum-magnesium alloy plate by multiple times by using the heat-insulating coating of the embodiment 5-9 and the comparative example 1-2, wherein the coating is required to be carried out after the surface is dried by coating the surface once, the total coating thickness is 6mm, after the coating is completely cured, heating one surface of the coated substrate to 900 ℃ by using high-temperature equipment with temperature display as a heat source, keeping the temperature for 5min, testing the temperature of the other surface by using a surface temperature tester, and calculating the heat-insulating temperature difference.
And (3) testing heat resistance: selecting a steel plate with the thickness of 1mm, cleaning the surface of the steel plate with the size of 20cm multiplied by 20cm, completely drying the steel plate, brushing the high-temperature-resistant heat-preservation coating of the embodiment 5-9 and the comparative example 1-2 with the thickness of 0.5mm on two sides and the periphery of the steel plate, after completely curing, using high-temperature equipment with temperature display as a heat source, respectively heating the steel plate to 1300 ℃, keeping for 15min, taking out and cooling, observing the surface condition of the coating, and ensuring that the steel plate does not blister, does not generate layers and does not fall off to be OK.
