Due to the absolute monopoly of solvent-based system, a large number of VOC emissions into the atmosphere, not only causing air and water pollution, but also harmful to human health and energy-saving emission reduction. Since the western developed countries to limit VOC emissions laws and regulations and the oil crisis in the 1970s, the paint industry gradually to clean and resource-saving direction. Therefore, all kinds of environmentally friendly coatings such as water-based coatings, radiation-cured coatings, solvent-free coatings and high-solids coatings become an important direction of the development of coatings, among them, water-based coatings have become a research hotspot because of their excellent environmental friendliness and safety.
