摘　　要：为了提高建筑的整体防水性能和耐久性,分析基于大数据的装配式建筑密封胶应用性能可靠性。使用基于Python的网络爬虫技术构建装配式建筑密封胶相关专利功能语料库,以此为基础制备装配式建筑用硅烷改性密封胶。测试硅烷偶联剂用量为0.4%~3.2%时对密封胶表干时间、固化时间、粘接强度以及稀释剂用量对密封胶拉伸强度影响,最后测试光照老化和浸水老化对密封胶耐老化性能影响。试验结果表明,硅烷偶联剂用量为1.6%时表干时间较短,固化时间较优且粘接强度较高,稀释剂用量为11%时密封胶拉伸强度最优。该密封胶经过长时间光照老化、浸水老化和加热老化后具有较强耐老化性能。In order to enhance the overall waterproof performance and durability of buildings,an analysis was conducted on the reliability of the application performance of sealants for prefabricated buildings based on big data.The web-crawler technology based on Python was utilized to construct a functional corpus of patents related to sealants for prefabricated buildings.On this foundation,silane-modified sealants for prefabricated buildings were prepared.The effects of the dosage of silane coupling agent in the range of 0.4%~3.2%on the surface-drying time,curing time,and bonding strength of the sealant,as well as the effect of the diluent dosage on the tensile strength of the sealant,were tested.Finally,the impacts of light aging and water-immersion aging on the aging-resistance performance of the sealant were investigated.The experimental results indicated that when the dosage of the silane coupling agent was 1.6%,the surface-drying time was relatively short,the curing time was optimal,and the bonding strength was high.When the diluent dosage was 11%,the tensile strength of the sealant reached its optimal value.This sealant demonstrated strong aging-resistance performance after undergoing long-term light aging,water-immersion aging,and heating aging.
