摘　　要：以废旧橡胶集料作为轻质保温材料,结合可再分散胶粉、木质纤维和甲基纤维素醚等制备了橡胶集料干粉砂浆,对其柔韧性、容重、粘结强度和导热系数等性能进行了研究。结果表明:研制出的橡胶集料干粉砂浆比普通干粉砂浆具有容重轻、柔韧性好、粘结强度高、导热系数低等特性,且施工方便,操作简单,及具有良好的保温性能,节能效果显著。In this paper, different compound ratio of the crumb rubber dry-mixing mortar,waste rubber aggregate as being lightweight aggregate, redispersible polymer powders lignocelluloses, methylcellulose etc, were compounded, based on the research of their main properties such as flexibility, bulk density, bonding strength and thermal conductivity. The results show that the crumb rubber dry-mixing mortar has many advantages over normal dry powder mortar, such as light bulk density, high bonding strength, good flexibility and low thermal conductivity. In addition,it has convenient construction, simple operation, excellent thermal insulation performance and remarkable energy-saving effect.
