摘要： 针对聚丙烯酰胺类凝胶防火玻璃隔热和耐候性不足的缺点，采用聚丙烯酰胺（PAM）为第一网络、聚乙二醇2000（PEG2000）为第二网络制备了PAM/PEG互穿网络凝胶防火玻璃，通过透光率测试仪、热重红外联用仪和锥形加热器等，研究PAM/PEG互穿网络结构对防火玻璃透光、隔热和耐候性的影响。研究结果表明，PAM/PEG互穿网络的构建能够有效提升防火玻璃的隔热性能并保持高透光率；提高PAM/PEG防火凝胶中PEG2000的含量能极大增强互穿网络结构，赋予防火玻璃更优异的耐候性能；当PEG2000添加量为4%时，防火玻璃表现出优异的综合性能，其在168 h时人工加速老化前后的3 600 s背火面平衡温度相比于未添加PEG2000的防火玻璃下降了46.0%。

Abstract: An interpenetrating network hydrogel fireproof glass was developed to address the shortcomings of insufficient thermal insulation and weather resistance of polyacrylamide hydrogel fireproof glass. The interpe-netrating network hydrogel fireproof glass was prepared with polyacrylamide (PAM) as the first network and polyethylene glycol 2000(PEG2000) as the second network. The effects of PAM/PEG interpenetrating network structure on the light transmittance, thermal insulation and weather resistance of fireproof glass were studied by light transmittance tester, simultaneous thermal analysis-fourier transform infrared spectroscopy tester and cone heater. The results show that the construction of PAM/PEG interpenetrating network effectively improves the thermal insulation performance of fireproof glass while slightly maintaining a high degree of transparency affecting the light transmittance. Increasing the content of PEG2000 in PAM/PEG fireproof hydrogel can greatly promote the enhancement of interpenetrating network structure and endow fireproof glass with more excellent weather resistance. When the addition amount of PEG2000 is 4%, the fireproof glass shows excellent comprehensive performance. The backside equilibrium temperature at 3 600 s after 168 h artificial accelerated aging decreases by 46.0% compared to that of the fireproof glass without PEG2000.
