Embodiment 1
[0017] A method for preparing medical crepe paper, comprising the following steps: taking northern wood pulp as fiber raw material, successively pulping, long fiber free beating, refining, and homogenizing, adding antibacterial agents, and adding polyoxyethylene stearate Non-ionic softener, papermaking, wet vat crepe, drying machine to make medical crepe paper.
[0018] The step of adding the antibacterial agent is: first add m-hydroxycinnamic acid and persulfate to the fiber raw material after homogenization, the mass ratio of the three is 100:10:0.15, and add dropwise at a speed of 20 mL / min under stirring Manganese acetate solution with 5% mass of m-hydroxycinnamic acid was reacted at 230 °C for 60 min under nitrogen atmosphere and then allowed to stand for 20 min.
[0019] The steps of adding the softener are as follows: After the softener is diluted with water, it is added continuously and evenly within 5 minutes at the outlet of the pulp pump according to the total amoun...
Embodiment 2
[0022] A method for preparing medical crepe paper, comprising the following steps: taking northern wood pulp as fiber raw material, successively undergoing pulping, long-fiber free beating, refining, and homogenizing, adding antibacterial agents, and adding polyoxyethylene stearate Ester non-ionic softener, paper making, wet vat creping, spraying water repellent-30 (commercially available) on the surface of medical crepe paper, and drying in a dryer to make medical crepe paper.
[0023] The step of adding the antibacterial agent is: first add m-hydroxycinnamic acid and persulfate to the fiber raw material after homogenization, the mass ratio of the three is 100:20:0.3, and add dropwise at a speed of 30 mL / min under stirring Acetate solution with 15% mass of m-hydroxycinnamic acid. Acetate is a mixture of equimolar zinc acetate and calcium acetate. Under nitrogen atmosphere, react at 200 °C for 50 minutes and then let it stand for 20 minutes.
