摘　　要：开发一款具有耐老化性能的罩面清漆,不仅可以起到屏蔽紫外线的功效,而且方便施工,具有极佳的便捷性与适用性。实验结果表明,实验开发的罩面清漆具有优异的耐老化性能,涂层整体抗老化性能的明显提升,紫外吸收光谱表明,UV-7751W相较于DW-123(N)在紫外波段有更宽泛的响应区间,表现出更良好的抗紫外老化性能,且复配紫外光吸收剂性能更优,其他基础涂膜性能如耐沾污性(<10%)和耐洗刷性(>10000次)远超标准,这对于长久地保持建筑物清洁自然,延长建筑物的翻新周期,节约自然资源至关重要,符合新时代的发展要求。An anti-ageing topcoat was developed,not only shielding UV radiation but also facilitating application,offering superior efficiency and versatility.Experimental results demonstrate that the topcoat developed exhibits excellent ageing resistance,with significantly improved overall ageing resistance.The UV absorption spectrum shows that UV-7751W displays a broader response range in the UV spectrum compared with DW-123(N),indicating superior UV ageing resistance.Additionally,if mixed with UV absorber,it exhibits better performance,while other fundamental coatings properties such as stain resistance(<10%)and scrub resistance(>10000 cycles)far exceed industry standards.This is essential for maintaining buildings'cleanliness and natural appearance over the long term,extending the renovation cycle of buildings,and conserving natural resources,thus aligning with the requirements of the new era.
