摘要：为提高水性聚丙烯酸酯木器漆的耐磨性和硬度,进行纳米Al2O3浆料的制备及其对水性木器漆改性的研究,探讨分析不同制备方法和Al2O3添加量对漆膜耐磨性和硬度的影响。结果表明:以聚丙烯酰胺为分散剂、聚乙二醇和辛基酚聚氧乙烯醚为润湿剂、聚乙烯吡咯烷酮为稳定保护胶,在高速搅拌下制成的纳米Al2O3浆料,在透射电镜下观察发现纳米Al2O3颗粒分布均匀,具有良好的分散性;在不影响漆膜透明度的情况下,漆膜耐磨性和硬度随Al2O3添加量增加得到提高,添加量在1.5%时漆膜具有较好的耐磨性和硬度;纳米杂合工艺法的漆膜耐磨性和硬度优于后添加法制备的水性木器漆涂膜。
The preparation of nano-Al2O3 slurry and modified waterborne wood coating with nano-Al2O3 slurry were studied in this paper to improve the wearing resistance and hardness of the polyacrylate coating on the surface of wood.The effects of the preparative technique and the contents of nano-Al2O3 on wearing resistance and hardness were discussed.The results showed that nano-Al2O3 slurry,which was prepared with polyacrylamide,polyglycol,polyoxyethylene octyl phenyl ether and protective colloid by bead mill and ultrasonic device,stored stably and was suitable for the system of waterborne coating.The slurry had good dispensability and Al2O3 kept in nano size observed by TEM.The films have good wearing resistance and hardness when Al2O3 content reach 1.5% without change the transparence by additive.The wearing resistance and hardness of the hybrid films were better than that of the films mixed with nano additive.
