Abstract

The paper briefly describes the influence of marine environment on durability of structure, and introduces the technological advantage of pure polyurea technology, and studies the influence of different temperature and humidity curing conditions on adhesion performance. The surface appearance and structural morphology of pure polyurea are investigated with scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FT-IR) after QUV aging. An introduction of application of pure polyurea to Hong KongZhuhai-Macao Bridge and Qingdao Bay Bridge is also given. It is shown that pure polyurea technology can undertake the mission of protection to Qingdao Bay Bridge with excellent long-term protective ability and strong resistance to QUV aging.
