Description

technical field [0001] The invention relates to the technical field of environment-friendly resin automotive coatings, in particular to a preparation method and application of an antibacterial nano-graphene oxide inclusion TiO2 acrylic resin. Background technique [0002] In recent years, with the continuous development of nanotechnology, the advent of nanomaterials with stable performance has opened up a new way for the preparation of high-performance polymers, in which nano-TiO2 has very good ultraviolet light holes ~ TiO2 adsorption compound sterilization Effect, on the one hand, it can produce special properties such as surface effect, volume effect, quantum effect and macroscopic tunnel effect. Under the irradiation of ultraviolet light or visible light, nano-TiO2 can decompose freely moving negatively charged electrons in water and air. At the same time, positively charged holes are left. This hole effect can produce active oxygen with strong chemical activity and reac...
