Problems solved by technology

However, a large amount of dregs produced after the extraction of Chinese herbal medicines have caused serious environmental problems.
The early treatment of medicinal residues was mainly landfill, incineration and stacking, etc. These methods caused serious environmental pollution and huge waste of resources.
[0003] Due to the strict hygienic requirements of the paper used for pharmaceutical packaging, the use of dyes is strictly prohibited, so most of the currently used pharmaceutical packaging paper uses bleached wood pulp as raw material, and the finished paper is white and the color is relatively monotonous.

Embodiment 1

[0027] (1) Soak polyvinyl alcohol in cold water for 2 hours, and control the temperature at 10°C. Then dilute to a mass concentration of 7.0%, stir at a speed of 400r / min, heat the steam to 90°C for boiling, keep it warm for 1 hour, add water to dilute to a mass concentration of 2.0%, and keep warm at 70°C;

[0028] (2) Polyvinyl alcohol solution is made into sizing material, and the sizing material solid content is 1%, carries out sizing on paper machine surface sizing machine and obtains medicine residue paper, and sizing amount is 2g / m 2 , the basis weight of the paper is 80g / m 2 .

[0029] Composition ratio of pulp raw materials: 70% coniferous wood + 30% hardwood, controlled beating degree 40°SR, wet weight 4.3g.

Embodiment 2

[0031] (1) The ganoderma lucidum content is about 10% and the concentration is that the NaCl of 1% is soaked 20h stand-by for 20h; Then the processed medicinal residues are processed once with a thread rolling machine, and then the medicinal residues are passed through two stages of disc grinding ( The first refining gap is 1mm, and the second refining gap is 0.2mm). During the whole preparation process, the slurry concentration of the dregs is kept at 20% (referring to the ratio of ganoderma lucidum solid content to water), and stored for use.

[0032] (2) Soak polyvinyl alcohol in cold water for 2 hours, and control the temperature at 11°C. Then dilute to a mass concentration of 7.0%, stir at a speed of 400r / min, heat the steam to 90°C for boiling, keep it warm for 1 hour, add water to dilute to a mass concentration of 2.0%, and keep warm at 70°C;

[0033] (3) mixing sizing material relative to polyvinyl alcohol quality 5% drug residue slurry and polyvinyl alcohol solution,...

Embodiment 3

[0037] (1) The ganoderma lucidum content is about 20% medicinal dregs soak 21h stand-by with the NaCl concentration of 1.5%; Then the medicinal dregs after the treatment is processed once with a silk rolling machine, and the medicinal dregs are passed through two stages of disc grinding ( The first refining gap is 1.2mm, and the second refining gap is 0.4mm). During the whole preparation process, the slurry concentration of the dregs is kept at 25% (referring to the ratio of ganoderma lucidum solid content to water), and stored for later use.

[0038] (2) Soak polyvinyl alcohol in cold water for 4 hours, and control the temperature at 12°C. Then dilute to 7.0% concentration, stir at 600r / min, heat up steam to 95°C for boiling, keep warm for 2 hours, add water to dilute to 2.5% concentration, and keep warm at 75°C.

[0039] (3) mixing 10% drug residue slurry and polyvinyl alcohol solution with respect to the polyvinyl alcohol quality to form a sizing material, the sizing mater...

Abstract

The invention belongs to the technical field of special paper, and particularly relates to medicinal residue paper as well as a preparation method and application thereof. The preparation method comprises the following steps: soaking medicinal residue with the ganoderma content of 10-20% by using NaCl at the concentration of 1-3% for 20-24 h for use; treating the treated medicinal residue by using a thread rolling machine, and milling the medicinal residue by two stages to obtain medicinal residue pulp; mixing the medicinal residue pulp of which the mass is 5-25% of that of polyvinyl alcohol with a polyvinyl alcohol solution, and adding a sizing aid to obtain a sizing material; sizing the surface of a paper base by using a sizing machine to obtain the medicinal residue paper. The medicinal residue is applied to the sizing machine and is used for coating the paper base to prepare the medicinal residue paper, and the medicinal residue paper has a unique color of the medicinal residue, so that the problem that the color is simplex can be well solved; meanwhile, the made medicinal residue paper itself has a faint herbal fragrance, and is a packaging highlight.

Description

technical field [0001] The invention belongs to the technical field of special paper, and in particular relates to a medicine residue paper and a preparation method and application thereof. Background technique [0002] Traditional Chinese medicine resources are a huge treasure house left to us by our ancestors. With the development and utilization of traditional Chinese medicine resources, especially the advancement of modern industrial technology and the deepening of the industrial scale of traditional Chinese medicine production, the traditional Chinese medicine industry has been developed and huge economic benefits have been generated. However, a large amount of dregs produced after the extraction of Chinese herbal medicines have caused serious environmental problems. The early treatment of medicinal residues was mainly landfill, incineration and stacking, etc. These methods caused serious environmental pollution and huge waste of resources. [0003] Due to the strict ...
