摘要
建筑能耗在国家总耗能中的比例较大,泡沫塑料建筑作为外墙保温材料具有质轻、导热系数低等优点,但容易导致火灾等问题。基于国内外研究现状,对硫铝酸盐水泥基泡沫保温材料进行试验研究。利用硅藻土、聚乙烯醇(PVA)纤维、改性脲醛树脂对泡沫水泥进行增韧改性,从而获得热导率低、韧性好复合泡沫材料。为硫铝酸盐水泥基泡沫保温材料的实际应用提供理论依据。
The proportion of building energy consumption in the country′s total energy consumption is large,and the foam building has the advantages of light weight,low thermal conductivity and so on.Based on the current research,experimental research was done on sulphoaluminate cement based foam insulation materials.Diatomite,polyvinyl alcohol（PVA）fiber and modified urea formaldehyde resin were used to modify and improve the foam cement.Provide a theoretical basis for the practical application of thermal insulation materials for sulphoaluminate cement based foams.
