A compression-resistant high-strength chemical fiber paper tube relates to the field of chemical fiber paper tubes and comprises a paper tube body and two hard rubber rings, the two hard rubber rings fixedly sleeve the outer end face of the paper tube body, and the paper tube body is composed of a bobbin paper inner core layer, PVC hard plastic, a buffer protection layer and outer layer bobbin paper. According to the utility model, the hard rubber rings are sleeved at the edge areas of the two sides of the paper tube, so that not only is the section port of the paper tube effectively protected, but also the paper tube is effectively prevented from being impacted and damaged when the paper tube falls on the ground; the PVC hard plastic is embedded in the outer side of the bobbin paper inner core layer in the paper tube for shaping and reinforcing, compared with a traditional bobbin paper tube, the strength of the paper tube is greatly improved, and meanwhile the buffering protection layer is arranged on the ou
