摘要: 采用湿法反应改性纳米硫酸钡,考察了改性剂种类、改性剂用量、纳米硫酸钡粒径、改性时间、改性温度以及改性转速对改性后纳米硫酸钡活化度的影响,并用红外光谱仪和热重分析仪对改性后纳米硫酸钡的包覆情况进行了表征。实验结果表明,改性剂为钛酸酯偶联剂UP-801,改性温度为80 ℃,改性剂用量为纳米硫酸钡质量的5%,改性时间为30 min,改性转速为7 000 r/min,对粒径为34 nm的纳米硫酸钡悬浮液进行改性,可得到活化度为95.76%的粉末状纳米硫酸钡。

Abstract: Nano barium sulfate was modified with the wet reaction method.Effects of variety of the modifying agent,dosage of the modifying agent,particle size of the nano barium sulfate,modification time,modification temperature and modification speed on the activation degree of the modified nano barium sulfate were investigated.Using infrared spectrometer and thermogravimetric analyzer,the coating condition of modified nano barium sulfate was characterized.Experimental results showed that coupling agent of organic titanate UP-801 is the suitable modifying agent;modification temperature is 80 ℃;dosage of modifying agent is 5%;the modification time is 30 min;modifying rotational speed is 7 000 r/min.Modification of nano barium sulfate suspension with partical size of 34 nm,95.76% activation degree of the nano barium sulfate powder can be acquired.

Key words: nano barium sulfate, surface modification, characterization
