1、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。 关键词：保温材料，导热系数，性能 AbstraAbstractct: With the development of e

2、conomy, peoples living standard has gradually increased, people in the housing, with particular attention to insulation material, in recent years, Chinas insulation products industry structure produced apparent change, foam thermal insulation thermal insulation material proportion has increased year

3、 by year, rigid class insulation product ratio decreased year by year. The lightweight materials, hydrophobic materials, green materials and effective thermal insulation materials insulation materials will become the development trend. This paper mainly introduces the general situation of insulation
