摘要
运用生命周期评价方法,对我国3类典型建筑保温材料(聚苯板、岩棉板、硬泡聚氨酯板)功能单位(以单位质量kg计)生产生命周期过程中产生的资源、能源消耗和污染气体排放进行调研与分析,并计算获得3类保温材料生产生命周期不可再生资源消耗、能源消耗和温室效应影响。同时,为更好地比较不同保温材料之间的生命周期环境友好性差异,结合保温材料在不同区域的使用特性,将功能单位进一步扩展为"满足相同节能要求的单位面积(以m2计)产品生产",并进行计算分析。结果显示,以"单位质量kg"计,岩棉板生产生命周期环境影响最小,硬泡聚氨酯板次之,聚苯板最大;而以"满足相同节能要求的单位面积m2"计,则聚苯板生产生命周期的环境影响最小,岩棉板最大。
Based on the method of life cycle assessment,resource consumption,energy consumption and exhaust emission generated in the life cycle of three typical building thermal insulation materials （polystyrene board,rock wool board,and polyurethane foam board） functional unit （defined as specific mass kg） production in China were deeply surveyed and analyzed. And the depletion of non-renewable resource and energy and greenhouse effect of functional unit for the three products were calculated and analyzed. Besides,the functional unit was further expanded to building thermal insulation materials production per m2 meeting the same energy-saving requirement in order to directly compare difference of environmental friendliness among the three building thermal insulation materials,the corresponding life cycle environmental impact was also calculated and analyzed. The result showed that life cycle environmental impact from the rock wool board production was the least in per mass as functional unit,and life cycle environmental impact from the polystyrene board was the largest. However,when the functional unit was defined as building thermal insulation materials production per mE meeting the same energy-saving requirement,life cycle environmental impact from the polystyrene board was the least, and the rock wool board was the largest.
