High-performance ZSR/P(MMA/BA) composites with enhanced thermal and excellent water resistance properties

Acrylate had developed rapidly because of its excellent chemical resistance, high-gloss surface, and weather resistance. However, the poor heat resistance of acrylate limited its application in coatings. To overcome this problem, an organic–inorganic hybrid polymer of zirconium silicone resin (ZSR)-modified acrylate has been successfully synthesized by solution polymerization. The results indicated that the heat resistance of acrylate was significantly improved due to the Si  O  Si and Si  O  Zr structures of ZSR and the increased cross-linking density induced by ZSR. After the incorporation of ZSR, the decomposition temperatures of 5% of acrylate increased from 300.4 and 349.2°C. The performance of the ZSR/(P(MMA/BA)) showed no significant change in uniformly heating at 200°C for 24 h. The composite films showed hydrophobicity, with the contact angles increasing to more than 90°. The S4 sample displayed the outstanding comprehensive performance, that is, 5% weight loss at 341.3°C, water contact angle of 97.9°, elongation at break of 852%, and tensile strength of 9.9 MPa. The high-performance heat resistant coating is a promising material for application in architecture, decoration, and mechanical equipment.
