摘要：本文采用硝酸鋁和醋酸鋅為原料，聚乙二醇（PEG）為分散劑，以共沉淀法制備摻鋁氧化鋅（AZO）微粉。選用硅酸鈉和稀硫酸對(duì)已制備的AZO進(jìn)行表面包覆SiO2改性。采用超聲波將未經(jīng)過(guò)表面包覆和經(jīng)過(guò)表面包覆后的AZO微粉分散到聚合物聚乙烯醇縮丁醛（PVB）中，用共混法制備了一系列不同鋁摻雜量的PVB/AZO復(fù)合材料。主要研究了不同鋁摻雜量的AZO微粉及其包覆改性AZO微粉對(duì)PVB/AZO復(fù)合材料的力學(xué)性能、隔熱效果的影響。結(jié)果表明： PVB/ AZO 復(fù)合膜片對(duì)紫外光有屏蔽作用，在可見(jiàn)光區(qū)透過(guò)率較高，近紅外波段透過(guò)率有所下降，有一定的隔熱、耐熱效果。當(dāng)鋁摻雜量為2%時(shí)，復(fù)合膜片的拉伸性能較好。 關(guān)鍵詞：共沉淀法；摻鋁氧化鋅；表面包覆；聚乙烯醇縮丁醛；共混法；復(fù)合材料
Abstract：In this paper, aluminum nitrate and zinc acetate as raw materials, polyethylene glycol (PEG) as a dispersing agent, co-precipitation preparation of aluminum doped zinc oxide (AZO) micronized. The selection of sodium silicate and sulfuric acid has been prepared AZO coated SiO2 modified. Using ultrasound without surface coating and after the AZO micronized surface coating dispersion polymer polyvinyl butyral (PVB)，a series of different Al-doped Blend Method of PVB/AZO composite materials. The study of Al-doped AZO micronized coated modified AZO powder on the mechanical properties of PVB/AZO composite insulation, heat insulation effect . The results showed that: the shielding effect of PVB/AZO composite diaphragm UV high transmittance in the visible region, the near-infrared transmittance decreased, a certain degree of insulation, heat effect. When the aluminum doping amount is 2%, the composite diaphragm has good tensile properties.
