石膏板复合外墙内保温系统的实验研究

Experimental Study on Composite Internal Insulation System with Plasterboard in Exterior Wall

摘要: 以纸面石膏板作为基板，通过胶粘剂将保温材料与之复合得到石膏板复合外墙内保温板材，通过实验分析了复合保温板材的导热系数和力学性能，结果表明，以挤塑聚苯乙烯泡沫板(XPS)为保温材料的复合保温板材相比模塑聚苯乙烯泡沫塑料板(EPS)，具有更好的保温隔热性能和力学性能，但容重相对更大。复合保温石膏板外墙内保温系统中，选用XPS板相比EPS板，综合性能更佳。

Abstract: Composite internal insulation board for external wall was manufactured with gypsum board and insulation board by using adhesive. The composite insulation coefficient of thermal conductivity and mechanical properties of the plate were studied through the experiments. The results show that the composite board with XPS as insulation materials exhibited better thermal insulation and mechanical performance but relatively larger bulk density than those with EPS. The composite insulation plasterboard external wall internal insulation system would display better comprehen-sive performance if XPS was selected than EPS.
