Beschreibung
Zusammenfassung:	The invention discloses a photoaging-resistant hydroxy acrylic resin coating and a preparation method thereof. The preparation method comprises the following steps: mixing absolute ethyl alcohol, deionized water and a silane coupling agent KH570, reacting, adding silicon-coated TiO2 nanoparticles, preserving heat, and carrying out solid-liquid separation; mixing the obtained hyperbranched modified TiO2 nano particles with a solvent, heating to 120 DEG C, dropwise adding a mixture of methyl methacrylate, butyl acrylate, styrene, hydroxypropyl acrylate, acrylic acid, n-dodecanethiol and a first initiator, keeping the temperature, supplementing a second initiator, keeping the temperature, cooling a reaction system to 70 DEG C, adding N, N-dimethylethanolamine, heating to 70 DEG C, and reacting for 1-2 hours to obtain the hyperbranched modified TiO2 nano particles. Adding deionized water after fully stirring, and stirring; and uniformly stirring and mixing the obtained hyperbranched TiO2-hydroxy acrylic resin sec
