摘　　要：防腐涂料是钢结构建筑耐久性的有效保障措施,但是目前钢结构涂装过程存在能耗大、污染重,工序复杂问题。本研究使用一种新型免除锈防腐涂料,是一类环氧基双组分涂料,同时引入硅烷活性组分,具有将锈蚀产物转化为稳定保护层的特点,填充陶瓷颗粒,提高涂层的抗渗透性能,防腐寿命为普通环氧涂料的5倍。施工前对钢材表面处理仅需达到SA1.0级,实现带锈涂装,提高生产和施工效率,降低钢结构建筑的全生命周期成本和碳排放,可广泛应用于学校、医院、住宅等钢结构建筑。Anti-corrosion coating is an effective measure to ensure the durability of steel structures.However,there are many problems in the coating process of steel structures,such as high energy consumption,heavy pollution and complex processes.This study uses a new type of rust free anticorrosive coating,which is a kind of epoxy based two-component coating.At the same time,the silane active component is introduced,which has the characteristics of transforming the corrosion product into a stable protective layer.It is filled with ceramic particles,improving the anti-permeability of the coating,and the anticorrosive life is 5 times of that of ordinary epoxy coating.Before construction,the steel surface treatment only needs to reach Sa1 level to achieve rust coating,improve production and construction efficiency,and reduce the life cycle cost and carbon emissions of steel structure buildings,which can be widely used in schools,hospitals,residential and other steel structure buildings.
