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.

Abstract

The present invention relates to the field of papermaking. Aiming at the problem of insufficient antibacterial properties of medical crepe paper, a preparation method of medical crepe paper is provided, which uses northern wood pulp as fiber raw material, and successively undergoes pulping, long fiber free beating, refining and homogenization. Pulping, papermaking, wet vat wrinkling, and drying to prepare medical crepe paper, and adding polyoxyethylene stearate nonionic softener and antibacterial agent after refining the fiber raw material. The present invention selects polyoxyethylene stearate non-ionic softener to solve the softness of paper, meets medical requirements, and meets papermaking requirements, and adds antibacterial agents to fiber raw materials, so that medical crepe paper can pass through physical and chemical comprehensive antibacterial effects. , to obtain better antibacterial properties.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a method for preparing medical crepe paper. Background technique [0002] Medical crepe paper is a packaging material used for trolleys, operating room countertops, and sheets in sterile areas. It is suitable for sterilization of medical equipment after packaging. With the continuous improvement of people's living standards, and the shortcomings of traditionally used cotton packaging materials such as short shelf life and fiber deformation after repeated cleaning, crepe paper is mostly used in the market to replace traditional cotton cloth, which has a very broad market prospect. As a kind of disposable packaging material, it is used for the packaging of hospital regeneration equipment, which saves the recycling, cleaning, ironing, sorting, transportation and other links of cotton packaging, and is convenient to use. [0003] Chinese patent CN103161092B discloses a medical crepe paper...
