A chemical fiber paper tube with high flame retardance relates to the field of chemical fibers and comprises a paper tube body, the paper tube body is composed of a paper tube inner core body, inner bobbin paper, an asbestos connecting layer, outer bobbin paper and a fire-resistant paper layer, the inner bobbin paper is fixedly mounted on the outer end face of the paper tube inner core body, and the asbestos connecting layer is fixedly mounted on the outer end face of the asbestos connecting layer. The inner bobbin paper and the outer bobbin paper are fixedly connected through the asbestos connecting layer. Firstly, primary heat insulation and flame retardance are carried out on the outer layer of the paper bobbin through the distributed round asbestos strips and the fire-resistant paper layer covering the surface of the paper bobbin; meanwhile, the polypropylene waterproof coating coated on the surface of the fire-resistant paper layer can effectively prevent water and prevent water vapor from permeating and
