Abstract

The invention relates to a kind of paper, which provides a medical dialysis paper with good antibacterial effect, good air permeability, high strength and high production efficiency, comprising a paper base layer and a coating layer coated on the upper and lower surfaces of the paper base layer, the paper base layer Containing 65 to 80 parts by weight of hardwood and 20 to 35 parts by weight of softwood raw materials, the coating layer contains the following raw materials by weight: 70 to 85 parts of ethylene-vinyl acetate copolymer, 3 to 3 parts of polyacrylamide 4 parts, 3-5 parts of barium stearate, 15-20 parts of hydrogenated rosin, 5-7 parts of glycidyl tert-carbonate, 0.6-1.0 parts of tert-butyl hydroquinone, 0.3-0.9 parts of erucamide, ortho 0.2 to 0.4 parts of phenyl hydroxybenzoate.

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...
