摘要:

通过选取无水乙醇为溶剂,以SiO2气凝胶为溶质,制备SiO2气凝胶改性溶液,并将其应用于改善玻璃棉的保温性能。通过浸润及常压干燥的方法制取玻璃棉/SiO2气凝胶复合板,研究SiO2气凝胶的质量分数和浸润时间对其性能的影响,并与溶胶-凝胶法制备的玻璃棉/SiO2气凝胶复合板相比。研究表明SiO2气凝胶的质量分数和浸润时间对玻璃棉/SiO2气凝胶复合板的性能有显著影响。当SiO2气凝胶质量分数达到8%且浸润时间为20 min时,玻璃棉/SiO2气凝胶复合板的短期吸水率、热导率分别下降了38.09%、18.32%,抗压强度上升了102.89%。与溶胶-凝胶法相比,本方法具有制备周期短、工艺较为简洁、成本低等优点,更适宜于大规模生产应用。

Abstract:

The modified solution of SiO2 aerogel was prepared by selecting anhydrous ethanol as solvent and SiO2 aerogel as solute and was used to improve the thermal insulation performance of glass wool. Glass wool/SiO2 aerogel combined boards were prepared by infiltration and prevailing pressure drying. The influence of the mass fraction of SiO2 aerogel and the infiltration time on its performance was studied, and compared with the glass wool/SiO2 aerogel combined board prepared by sol-gel method. The results show that the mass fraction of SiO2 aerogel and infiltration time have significant influence on the properties of glass wool/SiO2 aerogel combined board. When the mass fraction of SiO2 aerogel reached 8% and the infiltration time was 20 min,the short-term water absorption and thermal conductivity of glass wool/SiO2 aerogel combined board decreased by 38.09% and 18.32% respectively, and the compressive strength increased by 102.89%. Compared with sol-gel method, this method has the advantages of shorter preparation cycle, simpler process and lower cost, and is more suitable for large-scale production.

Key words: silica aerogel, glass wool/SiO2 aerogel combined board, thermal conductivity, building energy consumption, composites, solution
