摘要
以天然腰果壳液为主要原料,采用溶胶-凝胶法与紫外光固化技术,制备了腰果酚/纳米二氧化硅复合涂膜;用透射电子显微镜观察了SiO2在涂膜中的分散情况;研究了SiO2含量对该涂膜理化性能的影响。结果表明,当SiO2含量低于10%时,SiO2粒子以纳米尺寸(20~45nm)均匀分散于涂膜中;涂膜具有优良的理化性能,其热稳定性和抗紫外线性随SiO2含量的增加而提高。
Cardanol/SiO2 nanocomposite coating film was prepared by cashew nut shell liquid and ethyl silicate via sol-gel process and UV curing technique.Dispersion of SiO2 in film was examined by TEM.Effect of SiO2 content on properties of the film was studied.The physico-mechanical and ultraviolet resistant properties of the coating film were also investigated.The results showed that the SiO2 is well dispersed in the film with particles of 20~45nm when its content is below 10%.And the physico-mechanical,dynamic mec...
