摘要： The present invention relates to a heat-ray-shielding sheet that includes, on a support, a heat-ray-shielding layer including heat-shielding microparticles and a resin binder filling a void part. The microparticles are made of tin-doped indium oxide (ITO) or the like and have an average particle diameter of equal to or less than 100 nm, the reflectance in the heat-ray-shielding layer at a wavelength of at least 2,000 nm is at least 15%, and the surface resistivity in the heat-ray-shielding layer is equal to or more than 10 6 Ω/□. Increasing the surface resistivity imparts a radio-wave-transmitting property, and causing longer-wavelength near-infrared light to be reflected boosts heat-ray-shielding efficiency while preventing thermal cracking and the like of a glass substrate. Additionally compounding the heat-ray-shielding layer with a near-infrared-absorbing dye, or disposing a reflecting layer in addition to the heat-ray-shielding layer allows the heat-ray shielding effect to be further improved.
摘要翻译：本发明涉及一种热辐射屏蔽片，其在支持体上包括包含隔热微粒的热射线屏蔽层和填充空隙部分的树脂粘合剂。微粒由锡掺杂氧化铟（ITO）等制成，并且具有等于或小于100nm的平均粒径，在至少2,000nm的波长处的热射线屏蔽层中的反射率是至少15％，且热射线屏蔽层中的表面电阻率等于或大于106Ω/□。增加表面电阻率赋予无线电波传输性质，并且导致反射较长波长的近红外光线，从而提高热射线屏蔽效率，同时防止玻璃基板的热裂纹等。另外，将热射线屏蔽层与近红外吸收染料混合，或者除了热射线屏蔽层之外还设置反射层，可以进一步改善热射线屏蔽效果。
