Abstract

A sterilized medical paper sued for packing bags of medical tools is made up through proportioning raw materials, breaking in water, beating, adding melamine-formaldehyde resin or cationic thermosetting synthetic resin strengthening agent PAE, shaping, and winding. Its advantages are high dry or wet strength and air permeability and automatic degradation after used.

Description

Technical field [0001] The invention relates to a paper and a production method thereof, in particular to a medical sterilization paper and a production method thereof. Background technique [0002] Medical devices need to be sterilized by high pressure steam or ethylene oxide gas repeatedly during use. At present, cloth bags are mostly used for sterilization of medical devices, which have the disadvantages of difficult preservation, complicated use and easy cross infection. Packing with disposable paper has the advantages of convenience and quickness, but the strength of the existing paper after being wet is not enough, it is easy to tear, and its air permeability cannot meet the requirements of sterilization. Contents of the invention [0003] In order to overcome the disadvantage that the existing paper has poor wet strength and cannot be used for sterilization under high temperature steam conditions, the present invention provides a medical sterilization paper, which ...
