Abstract
The invention relates to a production method of medical packaging paper with high bacteria blocking performance. The production method comprises following steps: polyester microfibers with the length of 1-2 mm and the width of 0.3-3 mu m are selected and dispersed in water firstly; then aluminum sulfate is added and mixed uniformly, CMC (carboxymethyl cellulose) is added and stirred for 5 min, and the mixture is uniformly mixed; bleached softwood chemical pulp and bleached hardwood chemical pulp are beaten until the beating degree is 16-35 degree SR and are mixed uniformly; modified polyester microfibers are added to the pulp and uniformly mixed; then the wet strength agent PAE, cationic starch and AKD are added, water is added, the mixture is diluted until the concentration is 0.1%-1.0%, cationic polyacrylamide is added and mixed uniformly, the product is subjected to papermaking, squeezing, drying, surface sizing and calendering on a paper machine, and the medical packaging paper with high bacteria blocking performance is prepared. With adoption of the method, the bacteria blocking performance of the medical packaging paper is improved, the medical packaging paper keeps good breathability, and the quality of the medical packaging paper is improved.
Description
Technical field
The present invention relates to a kind of production method of medical treatment resistance bacterium package paper.
Background technology
Medical treatment resistance bacterium package paper is widely used in the aseptic medical equipment packing of product, for medicine equipment forms bacterial micro-organism isolation barrier, prevent bacteriological infection, guarantee the use that medical device product is expected and storage life, guarantee the aseptic condition transporting and keep in condition of storage product.Medical treatment resistance bacterium package paper, except need meeting the packaging character of the most basic protection and isolation external environment, more focuses on the permanent stability of material function, with the adaptability of sterilising conditions and sterilization method, and the bacterium isolation characteristic of material and avirulence.The medical treatment resistance bacterium package paper that current China produces mainly is starched with bleached softwood wooden chemistry and bleaches hardwood chemical pulp for raw material, and be equipped with suitable chemical assistant, paper machine is manufactured paper with pulp to be formed., because softwood pulp average fiber length is about 1.5 ~ 3.0mm, wide 30 ~ 75 μm, the long 0.7 ~ 1.7mm of hardwood pulp fiber, wide 20 ~ 40 μm, therefore, its paper aperture formed that interweaves is large, and bacterium easily passes through.For this reason, before copy paper, pulp fiber need carry out suitable making beating process, fiber is made to produce suitable wire-dividing broom purification, to improve the felt properties between fiber, reduce paper aperture, but excessive making beating process again reduces the air permeability of medical treatment resistance bacterium package paper, affect the adaptability of itself and sterilization method, affect serviceability.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of high resistant bacterium performance medical package paper using production method, and its good permeability can be kept.
Technical solution of the present invention: add a certain proportion of modified poly ester microfiber in the mixed slurry of bleaching needle-point leaf pulp and bleached hardwood pulp, because polyester microfiber diameter only has 0.3-3.0um, be far smaller than the diameter of string, therefore, copy the medical package paper using made after mixing and there is tiny aperture, good gas permeability.
The inventive method is specifically:
Polyester microfiber dispersion and modification: the polyester microfiber length 1-2mm that the present invention selects, width 0.3-3.0um.Polyester microfiber is added to the water dispersed with stirring, dispersion concentration 0.1-0.5%.Then, add 0.1-1.0% aluminum sulfate (mass percent relative to microfiber), be uniformly mixed, add the mass percent of 0.2-2.0%CMC(relative to microfiber), stir 5 minutes, mix, for subsequent use.
Copy paper: it is 16-35 ° of SR that bleaching needle-point leaf pulp and bleached hardwood pulp are pulled an oar to beating degree respectively, mixes, and both ratios are 50-80:50-20, and slurry concentration is 1.0-5.0%.In this slurry, add modified poly ester microfiber, addition is the mass percent of 1.0-10.0%(relative to wood pulp), mix.Then, add 0.3-3.0% wet strength agent PAE(Polyamide-Polyamsne-Epichlorohydrin), 0.5-3.0% cationic starch, 0.05-0.5%AKD, mix, be diluted with water to concentration 0.1-1.0%, add 0.02%-0.06% cationic polyacrylamide (being the mass percent relative to wood pulp), mix, shaping that paper machine is manufactured paper with pulp, squeezing, dry, top sizing, press polish, obtained high resistant bacterium performance medical package paper using.
Beneficial effect of the present invention: the present invention proposes a kind of high resistant bacterium performance medical package paper using production method, improve the resistance bacterium performance of medical package paper using, and its good gas permeability can be kept, improve the quality of medical package paper using.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
The principle of the inventive method: because the diameter of polyester microfiber only has 0.3-3.0um, be far smaller than the diameter of string, therefore, in vegetable-fibre slurry, add polyester microfiber, the aperture of the paper that fiber interweaving is formed can be reduced, improve its resistance bacterium performance.Because the binding ability of polyester microfiber and string is poor, therefore, polyester microfiber is first carried out surface modification by the present invention, makes its fiber surface adsorb appropriate CMC, improves the binding ability of itself and string.
