摘要

本文制备了不同纳米二氧化硅含量(wt%为0 ~ 1.5%)的聚乙烯醇丁醛(PVB)涂层，以改善涂层的力学性能、防腐性能和热氧化稳定性。利用红外光谱(FT-IR)对涂层中纳米二氧化硅的存在进行了表征。采用盐雾试验研究了纳米二氧化硅PVB涂层的耐蚀性。研究了纳米二氧化硅对PVB涂层附着力、抗折强度、相对硬度和热氧化稳定性的影响。当纳米二氧化硅含量为1.2 wt%时，PVB涂层的力学性能、耐腐蚀性和热氧化稳定性得到显著改善。

Improvement of physical and thermal properties of polyvinyl butyral coating with nanosilica

In this paper, polyvinyl butyral (PVB) coatings with different nanosilica contents (0- 1.5 weight percent (wt%) were prepared for improving properties such as mechanical properties, corrosion protection, thermal oxidation stability of coating. Presence of nanosilica in coating was characterized by FT-IR. Corrosion resistance of PVB coatings containing nanosilica was investigated by salt mist testing. Effects of nanosilica on adhesion, flexural strength and relative hardness and thermal oxidation stability of PVB coatings were also examined. Nanosilica with content of 1.2 wt% significantly improved mechanical properties, corrosion resistance and thermal oxidation stability of PVB coatings.
