纳米ATO透明隔热涂料的制备与性能研究

以自制纳米氧化锡锑（ ATO）及其水性浆料和水性聚氨酯为原料，采用共混法制备出纳米 ATO透明隔热涂料。对纳米 ATO涂料的隔热性和透光性进行研究，结果表明：将通过溶胶 -凝胶法制备的 25 nm的 ATO粉体配制成水性浆料，与水性聚氨酯 SX-240共混制备出的纳米 ATO透明隔热涂料，具有较好的透明隔热性能。当涂膜厚度为 60 μm时，其可见光透过率（λ=600 nm）为 72.35%，平均红外透过率为 45.56%，隔热检测装置内温差达到 3~4 ℃。

Preparation and Properties of Nano ATO Transparent Thermal Insulation Coatings

In this study，nano-ATO transparent heat-insulating coatings was prepared byblending process using self-made nano antimony tin oxide（ATO）and its aqueous slurry andwaterborne polyurethane as raw materials.Through the study of the heat insulation and lighttransmittance of the nano-ATO coatings，it was shown that the ATO transparent heat insulationcoatings prepared with blending of an aqueous slurry of 25 nm ATO powder prepared by sol-gel method and an aqueous polyurethane SX-240 was featured by its good transparent heat in.sulation performance.When the coatings film thickness was 60 μm，the visible light transmit. tance（λ=600 nm）reached 72.35%，and average infrared transmittance 45.56%，and tempera. ture difference inside of the self-made insulation detection device reached 3~4°C.
