Abstract: Disclosed is an environmentally-friendly method for enhancing mechanical properties of a high antibacterial nano dialysis paper for medical protection, includes following steps: a, preparing pulp components, and taking 40-60 parts of hardwood pulp, 10-20 parts of polyvinyl alcohol fiber, 30-50 parts of softwood pulp, 10-20 parts of cellulose fiber by mass; b, putting the hardwood pulp, the polyvinyl alcohol fiber, the softwood pulp and the cellulose fiber into a beater for beating to make a pulp, and then adding modified chitosan accounting for 1-5% of a weight of the pulp into the pulp, and defibering for 10-20 minutes at a rotating speed of 1500-2000 revolutions per minute in a defibrator; and c, carrying out papermaking with the pulp after defibering to form a dialysis paper finished product.
