2013齐鲁研究生学术论坛-材料科学与工程分论坛 QiluGraduateAcademic Forum 玻化微珠-聚苯颗粒保温砂浆的性能研究 陈玉鹏，付兴华，陶文宏 (济南大学 材料科学与工程学院，山东 济南 250022） 摘 要：采用正交试验法研究了聚苯颗粒、憎水剂、引气剂、聚丙烯纤维的掺量对复合保温砂浆干密度、抗压强度、 3% 0.2% 0.4% 0.6% 吸水率及软化系数等性能的影响规律，获得的最优配比为：聚苯颗粒 、憎水剂 、引气剂 、聚丙烯纤维 ， 3 其性能为干密度228kg/m ，28d抗压强度0.54MPa，导热系数0.0596W/(m·K)。利用SEM 扫描电镜对复合保温砂浆进行了 微观结构形貌分析，初步探讨了作用机理。 关键词：复合保温砂浆；聚苯颗粒；憎水剂；耐水性 Study onProperties ofVitrified Beads-polystyrene Particles Insulation Mortar CHENYupeng FU Xinghua TAO Wenhong ， ， (Schoolof MaterialsScienceandEngineering,UniversityofJinan,Shandong,Jinan,250022) Abstract: Abstract: AAbbssttrraacctt:: Orthogonal testing method was used to study the effects of polystyrene particles, hydrophobic agent, air-entraining agent, polypropylene monofilament fiber on dry density, compressive strength, water absorption and softening coefficient of composite insulation mortar. The optimal ratio was obtained as: 3% of the weight are polystyrene particles, 0.2% is hydrophobic agent, air-entraining agent counts for 0.4wt% and polypropylene monofilament fiber 0.6%. The main performances of the mortar ， 3 were recorded as: dry density was 228Kg/m , 28 day compressive strength after conserved for 28 days was 0.54MPa, and thermal conductivity 0.0596W/(m•K). Microstructure of the composite insulation mortar was analyzed by SEM (scanning electron microscopy) andits function mechanism was studiedpreliminarily. Keywords: Keywords: KKeeyywwoorrddss:
