  • Description: The invention provides a preparation method of student practice book paper capable of efficiently releasing negative oxygen ions. The indexes of the practice book paper are as follows: the average smoothness of the front and back surfaces is 50-100s; the release amount of negative oxygen ions is 3600-4500/cm < 3 >; the coating weight of the coating is 2-4g/m < 2 >. The negative oxygen ions are applied to the practicing book paper, on one hand, the negative oxygen ions can be released, organic volatile matters such as formaldehyde and TVOC in printing ink can be inhibited, and the irritating odor of the ink can be reduced; on the other hand, the content of local negative oxygen ions in the air is improved, so that when people write or read, fresh air can be provided, eye fatigue can be relieved, and myopia can be prevented; meanwhile, the high negative oxygen ions can relieve brain fatigue, and the working and learning efficiency is improved. 本发明提供一种高效释放负氧离子的学生练习册纸的制备方法，所述练习册纸的指标如下：所述练习册纸的指标如下：平滑度正反面平均50～100s；
