摘 要:根据西北采暖地区外保温抹面胶浆的性能要求,对废旧轮胎橡胶颗粒在水泥基材料中的已有研究进行了分析。分析研究表明,废旧轮胎橡胶颗粒能够提高抹面胶浆的抗开裂性、抗冲击性和抗冻性,并能增强其隔声效果和保温性能。指出了在应用研究中,应设置模拟环境试验测试抗裂性,选择简易型的抗冲击试验,并着重研究低温施工性能和质量。面对应用橡胶颗粒时需进行界面改性的难题,对比了已有研究中不同改性剂的实用性和经济性,确定了初步的试验方案,并指出应结合工程应用对改性剂的使用方法进行深入研究。
Abstract : According to the performance requirement of plaster mortar for external thermal insulation system in northwest region with heating provision, the existing research of waste tire rubber particles in cementitious materials are analyzed, and the results show that the waste tire rubber particles could increase the crack resistance, impact resistance, frost resistance of plaster mortar, and also can strengthen sound insulation and thermal insulation properties. Attentions in application research are pointed out including using simulated environment experiment to test crack resistance, choosing simple impact resistance experiment and discussing the construction performance and quality in low temperature. Facing the technical problems of interface modifying when rubber particles are in application, the practicability and economy of different modifiers in former study are compared, the tentative testing program is defined, and the use-method of modifiers should be studied in-depth combined with engineering applications.
