摘要
利用红外光谱仪(IR)、释放气体分析仪(EGC)、表面分析仪和气相色谱仪等表征和研究了钛酸酯偶联剂NDZ-401对纳米碳酸钙表面物理化学性能的影响。结果表明,钛酸酯偶联剂NDZ-401中的-Ti-(O=PH-(OC8H17)2)2基团以化学键结合在纳米碳酸钙粒子表面。经1.5%(质量分数)左右NDZ-401处理的纳米碳酸钙具有良好的可分散性和较强的表面吸附能力。
Influence of NDZ-401 titanate coupling agent on surface properties of nano carbonate calcium were investigated by infrared spectrum analysis (IR), specific surface analysis (BET), evolved gas analysis (EGA) and inverse gas chromatography (IGC). The results showed that the group (-Ti-(O=PH-(OC8H17)2)2) was chemically bonded to surface of nano carbonate calcium. Optimal dispersibility and surface adsorbability were achived when NDZ-401 amount reached 1.5%.
