摘要
介绍了一种提高单组分水性木器漆硬度的方法,通过在水性丙烯酸乳液和水性聚氨酯树脂分散体的基础上,合理杂化纳米二氧化硅分散液,并利用新材料和特殊工艺解决相容性问题,从而制得高硬度(2H)、能满足水性家具漆市场需求的单组分水性木器漆。同时,通过单因素试验和响应曲面法来研究并直观展示各因素对涂膜硬度的影响,试验结果表明:随着水性聚氨酯树脂分散体在成膜物质中的比例提升,涂膜的硬度表现为先升后降;随着纳米二氧化硅分散液用量的增加和其在成膜物质中分散时间的延长,涂膜硬度上升,但上升到一定程度后不再提高。
A method to improve the hardness of one-component waterborne wo od paint was introduced,which could meet the needs of waterborne furniture market within a hardness≥2H,though reasonably hybridizing the nanometer silica dispersion on the selected aqueous acrylic emulsion and aqueous polyurethane resin dispersion,and using new material and special technology to solve the compatible problem.At the same time,the effects of various factors on the hardness of the coating film were studied and visually demonstrated by single factor experiment and response surface method.The experimental results showed that the hardness of the coating film increased with the increase of the proportion of the aqueous polyurethane resin dispersion in the film-forming material and then decreased.The hardness of the coating film increased with increasing the amount of nanometer-silica dispersion,also increased with increasing the dispersion time of nanometer silica in the film-forming material,but it does not continue rise after increasing to a certain extent.
