1水性汽车涂料的应用背景VOC(挥发性有机化合物)、氮氧化物及高强度的光照射会导致臭氧(O3)的形成,臭氧会聚集在可供呼吸的对流层,对人的呼吸系统和神经系统造成危害。因此降低臭氧的形成,是减少光化学污染,提高空气和水品质,从而提高地球整体环境品质的重要途径。进入21世纪后,全球汽车产业高速发展,汽车涂装用涂料也得到长足的发展,但目前我国汽车后市场用的汽车涂料仍以传统的溶剂型涂料为主,溶剂型涂料中含有大量VOC,在涂装过程中不仅对漆
1 Application Background of Waterborne Automotive Coatings Volatile organic compounds (VOCs), nitrogen oxides (NOx) and high-intensity light irradiation result in the formation of ozone (O3), which accumulates in the respirable troposphere and affects the human respiratory system and nerves System causes harm. Therefore, reducing the formation of ozone is an important way to reduce photochemical pollution, improve air and water quality, and improve the overall environmental quality of the earth. After entering the 21st century, the rapid development of the global automotive industry, automotive coatings have also been considerable development of coatings, but China’s automotive aftermarket automotive coatings are still the traditional solvent-based coatings, solvent-based coatings contain a large number of VOC, In the coating process not only for paint
