Embodiment 1
[0058] Multi-component doped tin oxide microparticles (average particle diameter 30nm) 15g, N-methyl-2-pyrrolidone (NMP) 23g, diacetone alcohol (DAA) 14g, methyl ethyl ketone 47.5g, and titanate series 0.5 g of the joint agent was mixed, and ball mill mixing was performed for 100 hours using zirconia balls with a diameter of 4 mm to prepare 100 g of a multi-component doped tin oxide dispersion (A liquid). Mix 600g of glycidyloxypropyltrimethoxysilane, 400g of aminopropyltriethoxysilane and 10g of hydroxybenzophenone, and use a magnetic stirrer in an oil bath at 60°C at a speed of 30-50rpm After stirring for 16 hours, it was aged at 60°C for 48 hours to obtain 1010 g of the target binder (synthetic liquid 1). 25 g of synthetic liquid 1, 38 g of isobutanol, 25 g of propylene glycol monoethyl ether, and 2 g of liquid A were mixed and stirred to prepare a coating material for forming a sunlight shielding film. This coating material for solar shielding film formation was apply|coa...
Embodiment 2
[0062] 15g of cesium tungsten bronze (CsxWO3) microparticles (average particle diameter 30nm), 23g of N-methyl-2-pyrrolidone, 14g of diacetone alcohol, 47.5g of methyl ethyl ketone, and 0.5g of titanate coupling agent The mixture was mixed, and ball mill mixing was performed for 100 hours using zirconia balls with a diameter of 4 mm to prepare 100 g of a dispersion liquid of cesium tungsten bronze (B liquid). 25 g of synthetic liquid 1, 14.7 g of B liquid, 23.3 g of isobutanol, 25 g of propylene glycol monoethyl ether, and 2 g of A liquid were mixed and stirred to prepare a coating material for forming a sunlight shielding film. Next, a sunlight shielding film was formed by the same procedure as in Example 1, and evaluation of the film was performed.
Embodiment 3
[0064] Antimony tin oxide (ATO) microparticles (average particle diameter 30nm) 15g, N-methyl-2-pyrrolidone 23g, diacetone alcohol 14g, methyl ethyl ketone 47.5g, and titanate-based coupling agent 0.5g The mixture was mixed, and ball mill mixing was performed for 100 hours using zirconia balls with a diameter of 4 mm to prepare 100 g of a dispersion liquid of antimony tin oxide (liquid C). 25 g of synthetic liquid 1, 38 g of isobutanol, 25 g of propylene glycol monoethyl ether, and 2 g of liquid C were mixed and stirred to prepare a coating liquid for forming a sunlight shielding film.
