【摘要】：采用钛酸酯偶联剂对载银磷酸锆进行改性,选用黏度法、红外光谱仪和扫描电子显微镜对表面改性效果进行分析。结果表明,改性后,载银磷酸锆的团聚现象明显改善,钛酸酯偶联剂在载银磷酸锆表面形成了化学接枝,并通过R基团与载银磷酸锆表面羟基反应,化学偶联在抗菌剂表面;钛酸酯偶联剂对载银磷酸锆取得明显改性效果,处理后粉体黏度更低,分散效果更强,改性效果更好。使用质量分数2.5%的钛酸酯偶联剂时,能达到最佳分散效果。
[Abstract]:Zirconium phosphate was modified by titanate coupling agent. The effect of surface modification was analyzed by viscosity method, infrared spectrometer and scanning electron microscope. The results showed that the agglomeration of zirconium phosphate loaded with silver was obviously improved after modification. The titanate coupling agent formed a chemical graft on the surface of zirconium phosphate loaded with silver, and the surface hydroxyl group of R group was reacted with the surface hydroxyl of zirconium phosphate loaded with silver, which was chemically coupled on the surface of antimicrobial agent. Titanate coupling agent has obvious effect on the modification of zirconium phosphate loaded with silver, the viscosity of the treated powder is lower, the dispersion effect is stronger, and the effect of modification is better. When the titanate coupling agent with 2.5% mass fraction is used, the best dispersion effect can be achieved.
