Development and application of high weather-resistant external windows film for construction.

Building glass films are generally applied from inside, but some building glass films such as exterior walls or domes cannot meet the needs of use, therefore it is of great practical significance to develop high weather-resistant external windows film for construction. This paper briefly introduces the structure design and preparation method of the high weather-resistant external windows film for construction, conducts optical performance test, mechanical performance test, weather resistance test, and application effect analysis. The results show that the high weather-resistant external windows film for construction made by reasonable structure design can be used in large-scale application because of its durable weatherability, heat insulation, energy saving, safety protection and self-cleaning effect. Its salt spray resistance, high and low temperature resistance performance is good. [ABSTRACT FROM AUTHOR]
