【摘要】：在建筑能耗中，围护结构对建筑能耗有很大影响，其保温隔热性能与降低建筑能耗和提高室内舒适性关系甚大，外墙外保温技术应运而生。其中粘贴保温板的薄抹灰外墙外保温系统（External Thermal Insulation Composite System，简称ETICS）已得到广泛应用。外墙外保温技术的应用，一方面减少了建筑物运行阶段的能耗，，另一方面增加了建筑材料生产过程的环境影响，但其全生命周期环境负荷有待深入研究。 根据我国膨胀聚苯板薄抹灰外墙外保温系统(EPS外保温系统)和岩棉板薄抹灰外墙外保温系统(岩棉外保温系统)的研究与应用现状，用生命周期评价方法定量计算其生命周期各阶段的资源、能源消耗和污染物排放，并进行环境影响评价。结果表明：EPS外保温系统和岩棉外保温系统排放的主要污染物是CO2，分别为23.5kg/m2和46.0kg/m2；EPS外保温系统环境影响最大的三种类型为酸化效应、光化学烟雾效应和温室效应，分别占总环境负荷的35.3%、22.0%和18.4%；对环境影响贡献最大的是干混砂浆，产生的环境影响占总环境负荷的52.3%，其主要的环境影响类型为不可再生资源消耗、光化学烟雾效应和水体富营养化效应；其次为EPS板，产生的环境影响占总量的45.3%，其主要的环境影响类型为温室效应、酸化效应和人体健康损害。岩棉外保温系统的主要环境影响是温室效应、酸化效应和光化学烟雾效应，分别占总环境负荷的29.1%、26.7%和20.0%；岩棉板生产过程产生的环境影响占总环境影响的51.1%，其主要的环境影响类型为酸化效应、温室效应和人体健康损害，干混砂浆对总环境影响的贡献为47.0%，其主要的环境影响类型为光化学烟雾效应、不可再生资源消耗和水体富营养化效应。 对比相同保温效果下EPS外保温系统和岩棉外保温系统的环境负荷情况，EPS外墙系统的环境协调性好。综合考虑保温性能和材料燃烧性能的情况下，岩棉板薄抹灰外墙外保温系统的环境协调性好。
[Abstract]:In the building energy consumption, the enclosure structure has a great influence on the building energy consumption, and its thermal insulation performance has a great relationship with reducing building energy consumption and improving indoor comfort. The exterior wall external insulation technology emerges as the times require. Among them, the thin plastering external wall thermal insulation system (External Thermal Insulation Composite System, (ETICS) has been widely used. The application of external wall external insulation technology, on the one hand, reduces the energy consumption in the operation stage of the building, on the other hand, increases the environmental impact of the production process of building materials, but its whole life cycle environmental load needs to be further studied. According to the research and application status of expanded polystyrene board thin plastering external wall insulation system (EPS external insulation system) and rock cotton board thin plastering exterior wall external insulation system (rock cotton external insulation system), The resource, energy consumption and pollutant emission in each stage of the life cycle were quantitatively calculated by the life cycle assessment method, and the environmental impact assessment was carried out. The results show that the main pollutants emitted by EPS external heat preservation system and rock cotton external heat preservation system are CO2, are 23.5kg/m2 and 46.0 kg / m2, respectively. The three types of environmental impact of EPS external heat preservation system were acidizing effect, photochemical smoke effect and Greenhouse Effect, accounting for 35.3%, 22.0% and 18.4% of the total environmental load, respectively. Dry mixed mortar has the greatest contribution to the environmental impact, which accounts for 52.3% of the total environmental load. The main environmental impact types are non-renewable resource consumption, photochemical smoke effect and water eutrophication effect. The second is EPS board, which accounts for 45.3% of the total environmental impact. The main types of environmental impact are Greenhouse Effect, acidizing effect and human health damage. The main environmental effects of rock cotton external heat preservation system are Greenhouse Effect, acidizing effect and photochemical smoke effect, accounting for 29.1%, 26.7% and 20.0% of the total environmental load, respectively. The environmental impact caused by the production process of rock cotton board accounts for 51.1% of the total environmental impact. The main environmental impact types are acidizing effect, Greenhouse Effect and human health damage, and the contribution of dry mixed mortar to the total environmental impact is 47.0%. The main environmental impact types are photochemical smoke effect, non-renewable resource consumption and water eutrophication effect. Compared with the environmental load of EPS external insulation system and rock cotton external insulation system under the same heat preservation effect, the environmental coordination of EPS external wall system is good. Considering the thermal insulation performance and material combustion performance, the environmental coordination of the external thermal insulation system of rock cotton board thin plastering exterior wall is good.
