Degradable melt-blown filter material as well as preparation method and application thereof

The invention provides a degradable melt-blown filter material as well as a preparation method and application thereof, and belongs to the technical field of non-woven fabrics formed by coating, adding or activating chemical glue or thermal plastic and the like. Polylactic acid is used as a main body, an organic charge enhancer, an inorganic charge enhancer, a hindered amine stabilizer, a lubricant and a plasticizer are added as auxiliary materials, melt-blowing and surface roughening construction are performed, and the degradable melt-blown filter material is obtained. The polylactic acid melt-blown filter material is used as a filter material layer, the charge storage amount of the polylactic acid melt-blown filter material is increased, the charge storage stability is enhanced, the material is efficient and degradable, and environmental pollution caused by the technological process is reduced. 本申请提供一种可降解熔喷滤料及其制备方法和应用，属于采取涂覆、加入或活化化学胶或热塑胶等形成非织造布技术领域。以聚乳酸为主体，添加有机电荷增强剂、无机电荷增强剂、受阻胺类稳定剂、润滑剂和增塑剂为辅料，熔喷、表面粗糙化构建，得到可
