In the field of cooling materials, ZnTiO (ZT) is still a new member that needs to be further studied. In this paper, pure cubic ZT was synthesized by the sol-gel method, and the effect of calcination temperature on ZT synthesis was investigated. The hydrophobic modification was carried out on ZT to prepare near-infrared reflective thermal insulation functional composite coatings based on silicone resin (SI). Compared with unmodified ZT (U-ZT), the modified ZT (M-ZT) exhibits better dispersion in the SI matrix, contributing to improved solar reflectance and anti-graffiti performance. The EnergyPlus software was used to simulate energy consumption in the air conditioning system. The excellent chemical stability and high NIR reflectance made the synthesized pigments potential candidates for energy-saving coatings. The simulation showed that homeowners could save $10.29 a month by applying an energy-efficient coating consisting of ZT to the walls and roofs of their buildings. Besides, these coatings show potential anti-graffiti application due to the exceptional repellency of coated surfaces against water-based ink, oily red marker, and paint.
在冷却材料领域，钛酸锌（ZT）仍是一个有待进一步研究的新成员。本文采用溶胶-凝胶法合成了纯立方相ZT，并研究了煅烧温度对ZT合成的影响。对ZT进行疏水改性，制备了基于硅树脂（SI）的近红外反射隔热功能复合涂层。与未改性的ZT（U-ZT）相比，改性后的ZT（M-ZT）在SI基体中表现出更好的分散性，有助于提高太阳反射率和抗涂鸦性能。使用EnergyPlus软件模拟空调系统中的能耗。合成颜料优异的化学稳定性和高近红外反射率使其成为节能涂料的潜在候选材料。模拟结果表明，房屋业主通过在建筑物的墙壁和屋顶上应用由ZT组成的节能涂料，每月可节省10.29美元。此外，由于涂层表面对水性墨水、油性红色记号笔和油漆具有优异的排斥性，这些涂料还显示出潜在的抗涂鸦应用前景。
