The current outdoor architectural design requires simplicity and beauty. However, most of the traditional building materials are bulky and inconsistent with the requirements of modern building design, while nanocomposite coatings can solve this problem. Based on the characteristics of outdoor architectural design, this paper designed and produced nano-silica + nano-TiO2 composite pure acrylic/silicon acrylic paint in the form of latex paint, which can make the painted wall smoother and more applicable to the environment. In the experiment, in order to configure the coating with the best performance, different nanomaterial components and different volume fractions of pigments and fillers were tested in this paper. The test results showed the modification effect of the nano-silica was better than that of the nano- TiO2; the silicone acrylic paint was better than the pure propyl paint. The prepared coating had a contrast ratio of 0.98, a hardness of 2H, a scrub resistance of 60,124 times, and an acid resistance of 710 hours with excellent performance, which met the needs of applications in outdoor architectural design.
