溶胶-凝胶法制备SiO2/有机硅杂化涂层的耐候性能研究
Study on Weather Resistance of SiO2/Organosilicon Hybrid Coatings Prepared by Sol-gel Method
摘要
Abstract
SiO2/organosilicon hybrid coatings were prepared via the sol-gel method,and the effects of different amount of substance ratios of tetraethyl orthosilicate(TEOS)to methyltrimethoxysilane(MTMS)on the coating structure and weather resistance were systematically investigated.The coatings were characterized by Fourier transform infrared spectroscopy,X-ray diffraction,contact angle measurement,adhesion testing,and gloss measurement.The weather resistance of the coatings was evaluated through artificial accelerated aging tests,and the influence of UV aging on coating performance was examined.The results showed that when the amount of substance ratio of TEOS to MTMS was 1∶1,the Si—O—Si network structure was most well-developed,and the coating exhibited excellent hydrophobic performance with a water contact angle of 103°.After 1 000 h of UV aging,the coating maintained a gloss retention rate of 87.5%,an adhesion rating of Grade 1,and no obvious cracking or peeling was observed on the surface.The SiO2/organosilicon hybrid coatings demonstrated outstanding weathering resistance and possess broad application prospects in the field of outdoor protective coatings.关键词
