摘　　要：为了得到综合性能良好的复合保温砂浆,通过正交试验方法,选择水用量、水泥掺量、膨胀珍珠岩掺量、粉煤灰掺量、聚丙烯纤维掺量、可分散乳胶粉掺量和引气剂掺量等7个影响因素对保温砂浆的干密度、压折比、抗压强度及导热系数等指标进行了研究,分析各因素对复合保温砂浆相应指标的影响显著性程度,结合因素间的交互分析及验证试验得到了最优配合比。In order to get perfect comprehensive properties of composite insulation mortar,anti-cracking agent was added to the expanded perlite insulation mortar. Through orthogonal experiment method,the influencing factors of water consumption,dosage of cement,expanded perlite,dosage of fly ash,polypropylene fiber dosage,dosage and air-entraining agent dosage of latex on dry density,compressive and flexural strength,compressive strength and thermal conductivity coefficient index of thermal insulation mortar are studied. After analyzing the influence significance level of various factors on the composite insulation mortar corresponding index,combined with factor interaction analysis and validation test,the optimal mixture ratio is obtained.
