The invention discloses a preparation method of degradable high-bacteria-resistance nano dialyzing paper for medical protection, which comprises the following steps: a, preparing slurry components, namely taking 10-20 parts by mass of cellulose fiber, 5-10 parts by mass of cellulose mercerized fiber, 8-12 parts by mass of viscose fiber and 3-8 parts by mass of polylactic acid fiber; b, putting the cellulose fibers, the cellulose mercerized fibers, the viscose fibers and the polylactic acid fibers into a pulping machine for pulping to obtain pulp; and c, performing papermaking on the pulp to form a dialyzing paper finished product. The dialyzing paper prepared by the invention is degradable, and has high bacteria resistance and high air permeability. 本发明公开了一种可降解高阻菌医疗防护用纳米透析纸的制备方法，包括如下步骤：a、配制浆料组分，按质量份取10-20份的纤维素纤维、5-10份的纤维素丝光化纤维、8-12份粘胶纤维和3-8份的聚乳酸纤维；b、将纤维素纤维、纤维素丝光化纤维、粘胶纤维和聚乳酸纤维放入打浆机中打浆制得浆料，c、对浆料进行抄造形成透析纸成品。本发明制备的透析纸可降解，具有高阻菌和高透气性能。
