This invention discloses a bio-based multi-peak crystalline particle reflective thermal insulation and waterproof coating, additives, and preparation method, belonging to the field of building chemical materials and green energy-saving coating technology. The system uses organosilicon-modified acrylic emulsion as a base material, combined with a specific pigment composition, hollow glass microspheres, bio-based hydrophobic multi-peak crystalline particles, additives, and water. The core of this invention lies in introducing polyhydroxyalkanoate powder with multi-peak particle size distribution and high crystallinity, and constructing a weather-resistant protective layer on its surface through a dry synergistic pretreatment with hindered amine light stabilizers, ultraviolet absorbers, and nano-zinc oxide. This coating achieves a balance between environmental protection and long-lasting performance: it not only possesses excellent dense waterproofing and mechanical properties, but also achieves superior high-temperature anti-leveling characteristics by constructing a stable surface micromorphology. The deep synergy between the weather-resistant layer and the thermal insulation system significantly enhances the coating's anti-aging ability, endowing it with durable high solar reflectivity and excellent dust and stain resistance.
