Abstract

In this paper, the wet modification method is compared with the grafting method to modify nano-barium sulfate. The effects of the modification method, the modification time, the modifier dosage, the modification temperature, and other factors on the degree of activation of modified nano-barium sulfate are investigated to solve the nano-barium sulfate agglomeration problems and to make it a suitable process for industrial production. Thermogravimetric analysis, infrared spectroscopy, and scanning electron microscopy are used to characterize the morphology and encapsulation of modified nano-barium sulfate. The grafting method is used to modify nano-barium sulfate with a modification time of 120 min, a modifier dosage of 27%, and a modification temperature of 80 °C. From the experimental results, a hydrophobic nano-barium sulfate in powder form with 76.86% activation degree and 77.41% oil absorption value is obtained.

接枝法改性纳米硫酸钡的研究

本文比较了湿法改性与接枝法改性纳米硫酸钡的效果。研究了改性方法、改性时间、改性剂用量、改性温度等因素对改性纳米硫酸钡活化程度的影响，以解决纳米硫酸钡的结块问题，使其适合工业生产。采用热重分析、红外光谱和扫描电镜对改性纳米硫酸钡的形貌和包封性进行了表征。采用接枝法对纳米硫酸钡进行改性，改性时间为120 min，改性剂用量为27%，改性温度为80℃。实验结果表明，获得了活性度为76.86%、吸油值为77.41%的粉体型疏水纳米硫酸钡。

期刊介绍： The Journal of Chemical Research is a peer reviewed journal that publishes full-length review and research papers in all branches of experimental chemistry. The journal fills a niche by also publishing short papers, a format which favours particular types of work, e.g. the scope of new reagents or methodology, and the elucidation of the structure of novel compounds. Though welcome, short papers should not result in fragmentation of publication, they should describe a completed piece of work. The Journal is not intended as a vehicle for preliminary publications. The work must meet all the normal criteria for acceptance as regards scientific standards. Papers that contain extensive biological results or material relating to other areas of science may be diverted to more appropriate specialist journals. Areas of coverage include: Organic Chemistry; Inorganic Chemistry; Materials Chemistry; Crystallography; Computational Chemistry.
