埃洛石纳米管的表面改性及对水性聚氨酯增强性能的研究
The surface modification of halloysite nanotubes and performance enhancement of waterborne polyurethane
摘要
Abstract
Halloysite nanotubes (HNTs) material was modified by silane coupling agent of 3‐aminopropyltriethoxysilane (KH550 ) .And then we prepared the modified HNTs (m‐HNTs) ,HNTs/waterborne polyurethane composite material and m‐HNTs/waterborne poly‐urethane composite material .The composite material was prepared through ultrasonic disper‐sion and mechanical blending .The morphology of HNTs and m‐HNTs were characterized by scanning electron microscopy(SEM );The structure and thermal stability were characterized by fourier transform infrared spectrometer(FTIR) and thermogravimetric analyzer (TGA);It was found that HNTs displayed as nanotubes with hollow structure ,KH550 have been successfully grafted onto the HNTs .As well as ,compared with HNTs ,It was found that m‐HNTs has better thermal stability .Finally ,effects of HNTs and m‐HNTs content on the thermal stability and film performance of waterborne polyurethane system were systemati‐cally investigated .The results showed that the thermal stability of composites was enhanced with the HNTs and m‐HNTs addition ,especially with the m‐HNTs .In addition ,since the adding of m‐HNTs the water resistance of composite was enhanced dramatically ,as well as the hardness and flexibility of film .关键词
