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.%Titanate coupling agent was used to the surface modification of silver-zirconium phosphate.Several characterization methods were carried out to analyze the results of surface modification such as viscosity method,FTIR and SEM.The results indicated that the agglomeration of silver-zirconium phosphate was significantly improved.Through the reaction of R radicals and hydroxy of silver-zirconium phosphate,titanate coupling agent was chemically grafted on the surface of silver zirconium phosphate.Titanate coupling agent has excellent effect on the surface treatment of inorganic particles at lower viscosity and stronger dispersion.The experimental results showed that the best modification effect was achieved using 2.5 ％ titanate coupling agent was 2.5％ yield the optimal dispersion effect at the mass ratio of 2.5％.
