preparation example Construction

[0040] Preparation method of basic liquid medicine:

[0041] The basic medicinal solution includes the following active ingredient extracts in parts by weight: Angelica, Codonopsis, Andrographis paniculata, and Shamiania chinensis each in an amount of 9% of the total weight of medicinal materials; Each is 16% of the total amount of medicinal materials;

[0042] Firstly, the effective components of Andrographis paniculata and Angelica sinensis are extracted by heating and reflux with 85% ethanol, and the ethanol is obtained as a filtrate after filtering and deslagging, and the ethanol is recovered to obtain the filtrate.

[0043] Secondly, boil Gongluomu, Shuangmianzhen, Qianjinbai, Jinyinggen, Mildew Spatholobus, and Codonopsis pilosula in water respectively, and obtain the corresponding filtrate after extraction, filtration and slag removal; Leave for re-extraction; this extract is combined with the first extract.

Embodiment 1

[0045] This embodiment provides a method for preparing paper for tender and sensitive skin, and the specific operation steps are as follows:

[0046] S1. Pretreatment: pretreatment with microwave radiation on Qianjinfang medicine dregs with a water content of 25%, with a microwave power of 400W and a microwave time of 40min, and set aside;

[0047]S2. Fermentation: Soak and wash the Qianjinfang herb dregs obtained in step S1 with deionized water until the washing water is neutral, dehydrate and disperse, then place it in a fermentation tank, and add 1 kg / ton of biological compound enzyme , after stirring evenly, under aerobic conditions, microwave radiation is used to process again, the microwave power is 1500W, and the microwave time is 60min, the material of Qianjin Fang medicinal residue is fermented, and after the fermentation is completed, it is filtered to obtain filtrate and filtrate;

[0048] S3. Washing: Repeatedly soak, disperse and wash the filtrate in step S2 with ...

Embodiment 2

[0057] This embodiment provides a method for preparing paper for tender and sensitive skin, and the specific operation steps are as follows:

[0058] S1. Pretreatment: pretreatment with microwave radiation on Qianjinfang medicinal residues with a water content of 45%, with a microwave power of 700W and a microwave time of 20min, and set aside;

[0059] S2. Fermentation: Soak and wash the medicinal residue of Qianjinfang obtained in step S1 with deionized water until the washing water is neutral, dehydrate and disperse, then place it in a fermentation tank, and add 1.5 kg / ton of biological compound enzyme , after stirring evenly, under aerobic conditions, microwave radiation is used to process again, the microwave power is 1000W, and the microwave time is 200min, the material of Qianjin Fang medicinal residue is fermented, and after the fermentation is completed, it is filtered to obtain filtrate and filtrate;

[0060] S3. Washing: Repeatedly soak, disperse and wash the filtrat...

Abstract

The invention relates to paper for young, tender and sensitive skin, 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, medicinal ingredient extracting, 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 paper has good tensile property; the prepared 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 thatthe hygienic characteristics of the paper are ensured, and the paper has good softness; and the medicinal ingredients are extracted from the pulping filtrate and are applied to the paper, such that the microbial infections can be prevented, and the paper does not have any irritation and side effects on the skin mucosa, and is suitable for people with young, tender and sensitive skin.

Description

technical field [0001] The invention belongs to the technical field of pulping and papermaking, and in particular relates to a paper for tender and sensitive skin 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...
