Abstract

The invention relates to medical paper and a preparation method thereof, and discloses a process for papermaking by using Qianjinfang medicine residue, wherein the process comprises: microwave pretreatment, fermentation, washing, paper making, extracting of medicinal ingredients from waste liquid, paper modification and the like. According to the present invention, the short fiber is prepared by using the Qianjinfang medicine residue, and the long fiber property of the cotton fiber is combined, such that the prepared medical paper has good tensile property; the prepared medical paper has remarkable wet strength through internal sizing and surface application; by using the microwave radiation method and the biological method, harmful chemicals are not introduced during the whole process, such that the hygienic characteristics of the paper are ensured; and the medicinal ingredients are extracted from the pulping waste liquid, and are applied on the paper, such that the obtained medical paper has good antibacterial effect, can prevent microbial infection, and has effects of cleaning, comfort and health during the use.

Description

technical field [0001] The invention belongs to the technical field of pulping and papermaking, and in particular relates to a medical paper and a preparation method thereof. Background technique [0002] The paper industry is one of the important basic industries of my country's national economy. Due to the large amount of sewage and solid waste generated during the papermaking process, the papermaking industry is also a processing and manufacturing industry with high resource and energy consumption intensity, large pollutant generation, and serious environmental impact. With the gradual expansion of the industry, the environmental impact of these sewage and solid waste has become increasingly prominent. [0003] The widely used papermaking pulping method now consumes a lot of energy, and the method of biodegradation is used to decompose lignin in various papermaking raw materials, instead of chemical pulping, to achieve zero discharge of water in the whole process of pape...
