摘要：与溶剂型木器漆相比,水性木器漆存在着耐磨性差、硬度低等缺陷,在木器漆中引入纳米无机材料是解决这些缺陷的有效方法。笔者对水性木器漆中添加纳米无机材料的种类和用量进行了优化,分别选取了3种表面改性纳米无机材料(组合):改性纳米氧化铝、改性纳米氧化硅、改性纳米氧化铝+改性纳米氧化硅,在苯乙烯丙烯酸酯(SAE)水性木器漆的制备过程中进行添加,研究了纳米无机材料的种类、用量及添加方式对水性木器漆耐磨性及硬度的影响。结果表明:当纳米氧化铝和纳米氧化硅的质量比为2∶1,总添加质量分数为1.5%时,水性木器漆的耐磨性和硬度较高,此时漆膜磨透转数2 000 r,铅笔硬度2 H。实验结果表明在水性木器漆中添加适量的复合纳米无机材料能很好地提高水性木器漆的耐磨性和硬度。
Since water-based wood coatings exist some disadvantages such as relatively low abrasion resistance and hardness compared to solventborne wood coatings,some studies of adding inorganic nano-materials have been explored to address the drawback. In this paper,three types of surface modified nano-materials,namely nano-alumina,nano-silicon dioxide and the mixture of them,were added into the styrene acrylate（ SAE） water-based wood coating,respectively.The influences of the different nano-materials,dosages and addition methods on the abrasion resistance and hardness of wood coating were investigated. High abrasion resistance and hardness of the wood coating were observed when the nanoalumina and nano-silicon dioxide were added jointly at a mass ratio of 2 ∶ 1. With the addition of 1.5% mass fraction of nano-slurry to styrene acrylate latex,the wear-out points of the wood coating film appeared after 2 000 r and the hardness was 2H. The experimental results showed that the addition of inorganic nano-materials with suitable proportion was helpful for improving the abrasion resistance and hardness of water-based wood coatings.
