摘要:通過膨脹珍珠巖改性實驗,探究了表面處理方法、粒徑尺寸、水解時間、水解溫度等因素對膨脹珍珠巖吸水率的影響,制備了膨脹珍珠巖復合相變儲能材料。利用差示掃描量熱法(DSC)對熱力學性能進行研究,定性分析了膨脹珍珠巖復合相變儲能材料在外墻保溫砂漿中的技術經濟性能。結果表明:水解時間為8 h,水解溫度為60 ℃時,改性膨脹珍珠巖的吸水率下降,憎水性顯著提高。
關鍵詞:改性膨脹珍珠巖;復合相變材料;水解沉積法

Abstract:The effects of surface treatment methods,particle size,hydrolysis time and hydrolysis temperature on the water absorption of expanded perlite were investigated through the experiment of dilated perlite,and the composite phase change energy storage material of expanded perlite was prepared. The thermodynamics of the composite was made by differential scanning calorimetry(DSC) to qualitatively analyze the technical and economic performance of expanded perlite composite phase change energy storage materials in exterior wall thermal insulation mortar. The results show that when the hydrolysis time is 8 h and the hydrolysis temperature is 60 ℃,the water absorption rate of the modified expansive perlite are decreased and the hydrophobicity of the modified expansive perlite is greatly improved. 
Key words:modified expanded perlite,phase change material,hydrolytic deposition method
