文档介绍：纳米二氧化硅改性紫外光固化上光油涂料的研究
摘要
本论文根据紫外光固化上光油涂料在应用过程中存在的耐磨性差和不耐划伤等问题,通过把紫外光固化技术与纳米材料制备方法结合起来,以提高紫外光固化上光油涂料的耐磨性能为主要目的,用溶胶凝胶法制备纳米SiO2凝胶,通过硅烷偶联剂与SiO2表面羟基反应对其进行原位改性,再将改性纳米SiO2 凝胶加入到光固化上光油体系中,制备了紫外光固化纳米复合上光油。采用傅立叶变换红外光谱(FTIR)、扫描电镜(SEM)和涂膜性能试验等对纳米复合上光油的结构与性能进行了研究。结果表明,改性后的纳米SiO2 在上光油涂膜中分散良好;在引入改性纳米SiO2 后,涂膜的耐磨性提高约50%,光泽度也有一定的提高。

Nano-silica modified UV-curable glazing oil coating research
ABSTRACT
This paper, according to uv-curable glazing oil coating application process in existence in the wear resistance of poor and not resistant to scratch, uv-curing technology and bining nanometer materials preparation methods, in order to improve the uv-curable glazing oil coating for the main purpose, the wear resistance of using sol-gel process), through nanometer SiO2 gel silane coupling agent and SiO2 surface hydroxyl reaction on the in-situ modification, again will be modified nano SiO2 gel to join uv-curable glazing oil system, uv-curable nano prepared polish oil. The Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and coating film performance tests on the nano glazing the structure and properties of oil were studied. The results show that the modified nano SiO2 in glazing oil film spread among good; In introducing a modified nano SiO2, film abrasion resistance increases by about 50%, glossiness also have improved.
