摘　　要：选用纳米Al2 O3 作为填料 ,用硬脂酸进行亲油处理 ,与羟基丙烯酸树脂或聚酯复合 ,制备了纳米透明耐磨涂料。红外光谱分析表明 :硬脂酸与纳米Al2 O3 表面的羟基进行了反应。用分光光度计、磨耗仪及摆杆硬度计测定了涂料的透明性和耐磨性 ,添加 15 % (质量分数 )的纳米Al2 O3 ,涂膜的耐磨性能提高了 10 0 % ,相对于有机玻璃底材耐磨性能提高了 2 75倍 ,可见光平均透过率大于 80 %A nano transparent abrasion compound coatings has been developed based on nano-scale Al 2O 3 as filler that is treated with hydrophobic stearic acid and compounded with hydroxyl acrylic resin or polyester resin. The IR analysis result has shown that the stearic acid reacted with the hydroxyl groups on the surface of nano Al 2O 3. The transparency and abrasion resistance of the coatings film are measured with spectrophotometer, pendulmn hardness tester and taber abraser. Incorporation of 15% of nano Al 2O 3 will increase the film abrasion resis-tance 100%, which is 2.75 times of that of PMMA substrate, and the transparency for visible light.
