摘要: 木塑材料具有良好的装饰性、加工安装性能和物理力学性能，经济环保，是近年来新兴的一种新型材料。运用热流计法，测量了5种木塑复合墙体和2种木塑单一板材墙体的传热系数，参照JGJ134－2010《夏热冬冷地区居住建筑节能设计标准》的要求，得出以下结论：①普通砖墙（10 mm厚水泥砂浆＋240 mm厚实心黏土砖＋10 mm厚水泥砂浆）已不能满足新规范的热工要求。②当建筑的体型系数0.4时，4种复合墙体都能满足规范要求。当体型系数＞0.4时，试件2（普通砖墙＋40 mm厚木塑龙骨＋20 mm厚木塑板）不能满足规范要求；试件3（普通砖墙＋40 mm厚木塑龙骨＋外喷25 mm厚发泡聚氨酯＋20 mm厚木塑板）、试件4（普通砖墙＋40 mm厚木塑龙骨＋30 mm厚木塑板，内填发泡聚氨酯）、试件5（普通砖墙＋20 mm厚木塑龙骨＋60 mm厚木塑板，内填发泡聚氨酯）均能满足规范要求。③试件3的传热系数最小，热工性能最好，构造最经济合理。④单一板墙比复合墙体厚度薄、自重轻，保温性能较高，更适合用作隔墙。60 mm厚单一板墙即可满足内隔墙的最低热工要求。120 mm厚单一板墙可满足外墙的热工要求。图3表3参10

Abstract: Wood-plastic composites （WPCs），in regards to ornamentation，processing，installation，and physical and mechanical performance，have favorable energy efficiency qualities for residential buildings. To analyze newly developed residential building materials，a heat flow meter method was used to measure the heat transmission coefficient of five walls：［W1. common brick wall （CBW）（10 mm cement mortar+240 mm common brick + 10 mm cement mortar）；W2.（CBW+40 mm WPC keel+20 mm WPC board）；W3.（CBW+40 mm WPC keel+25 mm polyurethane foam sprayed on the WPC board+20 mm WPC board）；W4.（CBW+40 mm WPC keel+30 mm WPC board filled with polyurethane foam）；and W5.（CBW+20 mm WPC keel+60 mm WPC board filled with polyurethane foam）］ and two kinds of single-material walls：［60 and 120 mm single-material boards （SMBs）］. These walls were compared with reference to design standard （JGJ 134－2010） for energy efficiency of residential buildings in hot summer and cold winter zones. Results showed that：（1）W1 did not meet the new thermal specification requirements. （2）When the building shape coefficient was0.4，all four composite walls （W2-W5） met requirements. However，when the building shape coefficient was＞0.4，W2 did not meet requirements，whereas W3-W5 did. （3）W3 had the minimum heat transmission coefficient and best thermal performance with the most inexpensive and most rational structure. （4）Compared with composite walls，single-material walls were thin and light weight with high thermal insulation performance. The 60 mm SMBs met the lowest thermal technology requirement for the inner partition wall, and the 120 mm SMBs met the thermal technology requirement for the outer wall. Thus，single-material walls were more suitable for use as partition walls. ［Ch, 3 fig. 3 tab. 10 ref.］
