保温材料的研究 摘要 随着经济的发展,人们的生活水平也逐渐提升,人们在住房时候,特别注意保温 材质,近年来,我国保温隔热行业的产品结构发生了明显的变化,泡沫塑料类保 温隔热材料所占比例逐年增长,硬质类保温隔热产品的比例逐年下降。其中轻质 化材料、憎水性材料、绿色环保材料和超效绝热材料将成为保温隔热材料的发 展趋势。本文主要介绍了保温材料的概况、物化性能、主要性能指标、发展前景 及选型依据,并对几种常用保温材料作了阐述,综合对比其各种性能指标,得出 工程推荐的保温材料。 :保温材料,导热系数,性能 关键词 Abstract : Withthedevelopmentofeconomy,people'slivingstandardhas graduallyincreased,peopleinthehousing,withparticularattention toinsulationmaterial,inrecentyears,China'sinsulationproducts industrystructureproducedapparentchange,foamthermalinsulation thermalinsulationmaterialproportionhasincreasedyearbyyear, rigidclassinsulationproductratiodecreasedyearbyyear.The lightweightmaterials,hydrophobicmaterials,greenmaterialsand effectivethermalinsulationmaterialsinsulationmaterialswill becomethedevelopmenttrend.Thispapermainlyintroducesthegeneral situationofinsulationmaterials,physicalandchemicalproperties, themainperformanceindicators,thedevelopmentprospectandthe basisforselection,andsomecommonlyusedinsulationmaterialsis expounded,comprehensivecomparisonofitsvariousperformanceindexes, theengineeringrecommendedinsulationmaterials. : Keywords Insulationmaterials,thermalconductivity,performance
