Preparation method of aramid pulp and aramid pulp prepared by adopting same

The invention relates to the field of organic fiber and its preparation, in particular to a preparation method of aramid pulp. The preparation method comprises the main steps that aramid fiber is sequentially subjected to corona treatment, humidification treatment, high-speed rotary pulverizer dry-method pulping and other technological processes. The method is short in technological process, low in energy consumption and harmless to the environment and does not adopt solvents and other organic materials, the obtained product is pure and free of impurity contaminations, the average length of the aramid pulp is 0.5-1.5 mm, the specific surface area is 5-12 g/m , the fibrillation degree is high, hairiness is rich, and the preparation method is suitable for the fields such as sealing materials. 本发明涉及有机纤维及其制备领域，具体涉及种芳纶浆粕的制备方法，其主要步骤为：将芳纶纤维依次通过电晕处理、加湿处理、高速旋转粉碎机干法制浆等工艺过程，该法工艺流程短、能耗低、不使用溶剂或其他有机材料，对环境无害，所得的产品纯净、无杂质污染，芳纶浆粕的平均长度为0.5～1.5mm，比表面积为5～12g/m，原纤化程度高，毛羽丰富，适用于密封材料等领域。
