Application of SW Silicon Graphene Non-removable Mold-Free Exterior Wall Insulation System Construction Technology

摘要

面向装配式与现浇混合建造中结构施工与外墙保温协同的需求，提出并应用SW硅墨烯免拆模外墙保温系统，将保温层与临时模板集成为一板两用。通过保温板排版固定、模板支撑搭设和浇筑期防护三项关键技术的闭环实施，在上榜工程中开展材料、安装与界面性能的体系化评估。结果表明，导热系数不大于0.045 W/m·K，体积吸水率不大于3.0%，燃烧性能等级A2-s1,d0；板缝宽度不大于2 mm，墙体垂直度2 m控制不大于3 mm；与混凝土基面粘结强度不小于0.20 MPa，冻融后保持率不小于80%。经济与环境效益方面，综合单位造价较传统做法下降90 CNY每平方米，关键路径缩短25天，碳排放减少8 kg CO₂e每平方米。研究表明，该系统在满足超低能耗围护的同时，兼顾施工便捷与性能稳定，具有推广应用潜力。

Abstract

To meet the requirements of structural construction and exterior wall insulation coordination in the mixed construction of prefabrication and cast-in-place methods, the SW graphene-free formwork insulation system was proposed and applied. The insulation layer and the temporary formwork were integrated into one board with dual functions. Through the closed-loop implementation of three key technologies including insulation board layout fixation, formwork support erection, and protection during the pouring period, a systematic evaluation of materials, installation, and interface performance was carried out in the listed project. The results show that the thermal conductivity is no more than 0.045 W/m·K, the volume water absorption rate is no more than 3.0%, and the combustion performance grade is A2-s1,d0; the joint width is no more than 2 mm, and the verticality of the wall within 2 m is controlled to be no more than 3 mm; the bonding strength with the concrete base surface is not less than 0.20 MPa, and the retention rate after freeze-thaw is not less than 80%. In terms of economic and environmental benefits, the comprehensive unit cost is reduced by 90 CNY per square meter compared to traditional methods, the critical path is shortened by 25 days, and carbon emissions are reduced by 8 kg CO₂e per square meter. The study shows that this system not only meets the requirements of ultra-low energy consumption for the enclosure but also takes into account the convenience of construction and stable performance, and has the potential for wide application.
