Synthesis and Carbon Emission Evaluation of High-Performance Polymer Insulation Materials for Rural Residential Buildings in Northern Shaanxi
A composite insulation material(SiO2-PUF)based on polyurethane foam and SiO2 aerogel was developed to meet the high-performance thermal insulation needs of rural residential buildings in northern Shaanxi.The thermal properties,mechanical properties,durability and environmental impact of the synthesized materials were comprehensively evaluated.Thermal performance tests showed that SiO2-PUF showed significant thermal insulation effect at high temperatures,and its cold end temperature was about 40℃lower than traditional materials.Mechanical property evaluation showed that under carbonization conditions at 900℃,the compressive strength of SiO2-PUF exceeded 100 kPa,which was much higher than traditional thermal insulation materials.In the durability evaluation,SiO2-PUF showed up to 95%structural and performance retention under simulated environmental stress.The environmental impact assessment adopted the life cycle assessment(LCA)method,and the results showed that the carbon emissions of SiO2-PUF were lower than traditional insulation materials in each life cycle stage.Cost-benefit analysis showed that although SiO2-PUF cost was slightly more in the raw material and manufacturing stages,its long-term energy efficiency and durability made the total cost of ownership lower than traditional materials.The research results can provide a high-performance,sustainable thermal insulation solution for rural residential buildings in Northern Shaanxi.
