摘要

以纳米硅溶胶为载体，葡萄糖为还原剂制备出稳定的纳米银溶胶，并对银溶胶的结构和粒径进行表征.选择热-紫外光双重固化乳液作为成膜树脂，以纳米银溶胶作为纳米抗菌剂，设计出纳米银改性水性木器涂料，讨论了不同质量分数的纳米银溶胶对漆膜抗菌性能和降解甲醛效果的影响.结果表明：当纳米银溶胶的质量分数为10％时，该水性抗菌木器涂料的漆膜性能优良，对大肠杆菌和金黄色葡萄球菌的灭菌率达到90％以上，在自然光下处理48 h后对甲醛的去除率可达70%.

Abstract

This paper discusses the stable nano-silver colloid with nano silica sol as carrier and glucose as reductant which has characteristics in structure and particle size of the sol. This synthesizing method uses thermal-UV dual curing emulsion as film-forming resin

nano-silver sol as antibacterial agents

and the design of waterborne antibacterial coatings modified by nano-silver. It also explores the effect of nano-silver sol in various mass fractions on antibacterial performance and formaldehyde degradation rate of waterborne wood coatings. The results show when mass fraction of nano-silver sol is 10%

the nano-silver antibacterial waterborne wood coatings have satisfactory performance with over 90% antibacterial rate against Escherichia coli and staphylococcus aureus. And after 48 h daylight the volatility of formaldehyde will reach 70%.
