[0040] Preparation method of basic liquid medicine:

[0041] The basic medicinal solution includes the following active ingredient extracts in parts by weight: 0.1-5 parts of atractylodes oil, 0.01-0.5 parts of berberine, 0.01-0.5 parts of eucalyptus oil, 0.01-0.5 parts of borneol, and 0.01-0.5 parts of menthol.

[0042] Wherein, herb oil can be prepared by the following methods:

[0043] Dry Atractylodes atractylodis, the drying temperature does not exceed 60°C, pulverize, pass through a 30-mesh sieve, and conduct CO 2 For supercritical extraction, set extraction pressure to 25MPa, temperature to 40°C, flow rate to 30-40L / h, extract for 4 hours, and collect volatile oil.

[0044] First, take by weighing herb oil, berberine and eucalyptus oil according to the formula, for subsequent use;

[0045] Secondly, Atractylodes atractylodis oil is mixed and dissolved in 95% ethanol to obtain Atractylodis oleifera alcohol solution;

[0046] Finally, mix mint and borneol, add berberine,...

Abstract

The invention relates to an antibacterial paper towel 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 antibacterial paper towel has good tensile property; the prepared antibacterial paper towel has remarkable wet strength through internal sizing and surface application; by using the microwave radiation method and the biological method, harmful chemicals are notintroduced 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 mixed with thebase medicine liquid component comprising Cortex Ailanthi, Sophora flavescens Ait, Cortex Moutan, frankincense and borneol, and the obtained mixture is applied on the paper, such that the obtained antibacterial paper towel has good anti-inflammatory and antibacterial effects, can prevent microbial infection, does not have irritation and side effects on the skin and vaginal mucosa, and is suitablefor women.

Description

technical field [0001] The invention belongs to the technical field of pulping and papermaking, and in particular relates to an antibacterial paper towel 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 pr...
