Embodiment 1

[0026] Tea polyphenols prepares the preparation method of formaldehyde scavenger, is characterized in that, comprises the following steps:

[0027] S1. Obtain the raw materials in the following parts by weight: 40-80 parts of tea polyphenols, 10-15 parts of Boston fern, 10-15 parts of yam, 10-15 parts of orchid, 10-15 parts of chamomile, 10- 15 parts of thyme, 10-15 parts of spearmint, 10-15 parts of jasmine, 10-15 parts of violet, 10-15 parts of Chlorophytum, 100-200 parts of water;

[0028] S2. Drying, pulverizing and filtering 40-80 parts of tea polyphenols to obtain completely dispersed tea polyphenols powder;

[0029] S3. Using quantum technology to process 100-200 parts of water to obtain 100-200 parts of quantum water;

[0030] S4. Put 40-80 parts of tea polyphenol powder and 100-200 parts of quantum water into a high-speed disperser, mix and dissolve at room temperature to prepare a tea polyphenol solution;

[0031] S5, with 10-15 parts of Boston fern, 10-15 parts of...

Embodiment 2

[0038] Based on Example 1, step S1 obtains the following raw materials in parts by weight: 40 parts of tea polyphenols, 10 parts of Boston fern, 10 parts of cocoon, 10 parts of orchid, 10 parts of chamomile, 10 parts of thyme, 10 parts of lemongrass Lanxiang, 10 parts of jasmine, 10 parts of violet, 10 parts of Chlorophytum, 100 parts of water.

[0039] In this embodiment, the formaldehyde scavenging efficiency is detected according to the following method: first collect the formaldehyde concentration in the air sample in the test cabin, and then spray 300g of formaldehyde scavenger evenly on three sheets of 1m 2 On the base paper, hang in the central position of the test cabin, collect the air sample in the test cabin after 72 hours to measure the formaldehyde concentration, calculate the absorption efficiency of formaldehyde according to the formaldehyde concentration; the removal efficiency of the formaldehyde scavenger prepared in this embodiment Capable of as high as 97.2...

Embodiment 3

[0041] The difference from Example 2 is that step S1 obtains the following raw materials in parts by weight: 60 parts of tea polyphenols, 13 parts of Boston fern, 13 parts of cocoon, 13 parts of orchid, 13 parts of chamomile, 13 parts of thyme, 13 parts of spearmint, 13 parts of jasmine, 13 parts of violet, 13 parts of Chlorophytum, 150 parts of water.

[0042] In this embodiment, the formaldehyde scavenging efficiency is detected according to the following method: first collect the formaldehyde concentration in the air sample in the test cabin, and then spray 300g of formaldehyde scavenger evenly on three sheets of 1m 2 On the base paper, hang in the central position of the test cabin, collect the air sample in the test cabin after 72 hours to measure the formaldehyde concentration, calculate the absorption efficiency of formaldehyde according to the formaldehyde concentration; the removal efficiency of the formaldehyde scavenger prepared in this embodiment Can be as high as ...

Abstract

The invention discloses a method for preparing a formaldehyde scavenger from TP (tea polyphenol). The method comprises the following steps: obtaining the TP, nephrolepis exaltata, syngonium podophyllum, aspidistra elatior, chamomile, thyme, mentha spicata, jasminum sambac, mallhiola incana, chorophytum comosum and water; drying, smashing and filtering the TP in sequence, so as to obtain completelydispersed TP powder; processing the water with a quantum technology, so as to obtain quantum water; placing the TP powder and the quantum water into a high-speed dispersion machine, so as to obtain TP solution; mixing the nephrolepis exaltata, the syngonium podophyllum, the aspidistra elatior, the chamomile, thyme, the mentha spicata, the jasminum sambac, the mallhiola incana and the chorophytumcomosum, adding water into the mixture for boiling, and concentrating the solution, so as to obtain plant extracting solution; mixing the plant extracting solution and the TP solution, so as to obtainthe formaldehyde scavenger. In the invention, the formaldehyde scavenger which has the advantages of being capable of removing formaldehyde efficiently, being safe and non-toxic and having no secondary pollution is prepared.

Description

technical field [0001] The invention relates to a method for preparing a formaldehyde scavenger, in particular to a method for preparing a formaldehyde scavenger from tea polyphenols. Background technique [0002] The main harm of formaldehyde is shown as the stimulation to skin mucous membrane. When formaldehyde reaches a certain concentration indoors, people will feel uncomfortable. Greater than 0.08mg / m 3 High formaldehyde concentrations can cause red eyes, itchy eyes, throat discomfort or pain, hoarseness, sneezing, chest tightness, wheezing, dermatitis, etc. Newly decorated rooms have higher levels of formaldehyde, which is the main cause of many diseases. [0003] At present, there are three main ways to control formaldehyde pollution or odor: one is to use activated carbon or some green plants; the other is to ventilate; the third is to use chemicals. The adsorption rate of activated carbon or some green plants is slow, and it is not obvious for indoor formaldehyd...
