Abstract

The invention relates to paper, and provides a medical dialyzing paper which is good in bacteria-blocking effect, excellent in air permeability, high in intensity, and high in production efficiency. The paper comprises a paper substrate, and coating layers coated on the upper surface and the lower surface of the paper substrate, wherein the paper substrate comprises 65 to 80 parts by weight of broadleaf wood, and 20 to 35 parts by weight of coniferous wood as raw materials; the coating layers comprise the following raw materials in parts by weight: 70 to 85 parts of ethylene-vinyl acetate copolymer, 3 to 4 parts of polyacrylamide, 3 to 5 parts of barium stearate, 15 to 20 parts of staybelite, 5 to 7 parts of tert-carbonic acid glycidyl ester, 0.6 to 1.0 part of tertiary butyl hydroquinone, 0.3 to 0.9 part of erucicamide, and 0.2 to 0.4 part of o-hydroxybenzoic acid phenyl ester.

Description

technical field [0001] The invention relates to a paper, in particular to a medical dialysis paper. Background technique [0002] Medical dialysis paper is mostly used in medical sterilization. One side is high-density polyethylene and the other side is dialysis paper, which is used to package medical devices for sterilization. In the application process, the dialysis paper is usually coated and printed , Bag making, that is, the most paper-plastic bag base paper. With the rapid development of the medical industry, the cost of cotton cloth materials and cleaning used in the past has continued to rise, and the production cost of medical devices repeatedly used in the disinfection supply center has also increased sharply. In addition, the preservation quality of sterile products is affected by many factors, and the use and management of cotton cloth is more difficult. Many medical institutions use paper-plastic bags and cotton cloth-based non-woven fabrics in the sterilizatio...
