摘　　要：采用熔融共混挤出压片的方法制备了聚乙烯醇缩丁醛/纳米锡掺锑隔热中间膜(PVB/3GO/ATO),研究纳米ATO用量对隔热中间膜的隔热性能、透光率、热性能及力学性能的影响。结果表明,当纳米ATO含量为0.3%时,中间膜抗拉强度最佳为26.86 MPa,相比PVB提升约35%,可见光透过率可达85%;当纳米ATO含量为0.9%时,红外光的透过率仅有55.5%;同时发现掺杂少量纳米ATO可增大隔热中间膜分解温度,降低导热系数,最低至0.205 W/(m·K)。Polyvinyl butyral/nano tin doped antimony insulation intermediate film(PVB/3GO/ATO)was prepared by melt blending extrusion pressing method,and the effect of nano ATO dosage on the insulation performance, transmittance, thermal performance, and mechanical properties of the insulation intermediate film was studied. The results show that when the content of nano ATO is 0.3%, the optimal tensile strength of the intermediate film is 26.86 MPa, which is about 35% higher than PVB, and the visible light transmittance can reach 85%;When the content of nano ATO is 0.9%, the transmittance of infrared light is only 55.5%;At the same time, it was found that doping a small amount of nano ATO can increase the decomposition temperature of the insulation intermediate film, reduce the thermal conductivity, and reach a minimum of 0.205W/(m· K).
