Examples
Example Embodiment
[0031] Example 1
[0032] Add 50g of magnesium oxide (Wuxi Zehui), 5g of zirconia (Eastern Zirconium Industry), and 5g of barium sulfate (Guangdong Xinmei) into 50g of deionized water at room temperature and 25°C, and stir at high speed for 1 hour until the dispersion is uniform. Then add 5 g of magnesium sulfate (Hunan Tancheng), stir for 20 minutes, and filter through a 400 mesh filter to obtain an inorganic heat reflective coating. The paint is drawn on a smooth aluminum plate to form an inorganic heat-reflective hair material with a thickness of 1000 μm.
Example Embodiment
[0033] Example 2
[0034] Add 40g of magnesium oxide (Wuxi Zehui), 5g of zirconia (Eastern Zirconium Industry), 15g of zinc oxide (Wuxi Zehui), and 5g of methyl triethoxysilane (Hubei Xinsihai) to 30g at room temperature and 25℃. In ionized water, stir at high speed for 1 hour until the dispersion is uniform. Then add 10 g of zinc sulfate (Hunan Tancheng), stir for 20 minutes, and filter through a 400 mesh filter to obtain an inorganic heat reflective coating. The paint was scraped on a smooth aluminum plate to form a 1000 μm thick inorganic heat-reflective hair material (ie, an inorganic cooling coating).
Example Embodiment
[0035] Example 3
[0036] 70g magnesium oxide (Wuxi Zehui), 5g antimony trioxide (Shanxing Antimony Industry), 5g barium sulfate (Guangdong Xinmei), 5g alumina (Shandong Aluminum Industry), 3g sodium methyl silicate at room temperature 25℃ (Hubei New Sihai) was added to 80g of deionized water and stirred at high speed for 2h until the dispersion was uniform. Then add 5 g of magnesium sulfate (Hunan Tancheng), stir for 20 minutes, and filter through a 400 mesh filter to obtain an inorganic heat reflective coating. The paint was scraped on a smooth aluminum plate to form a 1000 μm thick inorganic heat-reflective hair material (ie, an inorganic cooling coating).
