Problems solved by technology

[0003] At present, the methods for removing formaldehyde at home and abroad are mainly divided into physical methods and chemical methods. Physical methods mainly use physical adsorption and other methods to remove formaldehyde. , decomposition, complexation and other reaction principles. By developing a formaldehyde scavenger to remove formaldehyde and purify the air. This method has the characteristics of quick results, many types, and high technical threshold, and it has attracted more and more attention.
However, this formaldehyde scavenger obtained by chemical methods may often bring new pollution problems

Embodiment 1

[0024] Prepare formaldehyde scavenger by following method:

[0025] Obtaining of amino acid mixture: Commercially available food-grade amino acid raw materials are mixed according to the ratio of glycine, alanine, and proline at 2:2:1.

[0026] The acquisition of lemon extract, rose extract and chrysanthemum extract: commercially available water extract, the pH value of lemon extract is between 1.0-2.5, the pH value of rose extract is between 4.0-6.5, and the pH value of chrysanthemum extract The pH of the extract is between 3.5-6.0.

[0027] Obtaining of phosphate mixture: Commercially available food-grade raw materials are mixed according to the ratio of sodium tripolyphosphate, sodium pyrophosphate and sodium hexametaphosphate at a ratio of 1:1:1. .

[0028] Production of 100 kg formaldehyde scavenger:

[0029] (1) Weigh 0.5 kg of edible gelatin, 3 kg of amino acid mixture, 1 kg of lemon extract, 1 kg of rose flower extract, 1 kg of chrysanthemum extract, and add 93 kg o...

Embodiment 2

[0033] Amino acid mixture, lemon extract, rose extract, chrysanthemum extract and phosphate mixture were prepared in the same manner as in Example 1 above.

[0034] Production of 100 kg formaldehyde scavenger:

[0035] (1) Weigh 0.1 kg of edible gelatin, 1 kg of amino acid mixture, 3 kg of lemon extract, 2 kg of rose flower extract, 3 kg of chrysanthemum extract, and add 90.8 kg of deionized water;

[0036] (2) Add the above-mentioned weighed raw materials into the reaction kettle, slowly add 0.5 kg of the phosphate mixture, and stir at room temperature for 25 minutes until dissolved;

[0037] (3) After standing for 30 minutes, a light green transparent formaldehyde scavenger was obtained.

Embodiment 3

[0039] Amino acid mixture, lemon extract, rose extract, chrysanthemum extract and phosphate mixture were prepared in the same manner as in Example 1 above.

[0040] Production of 100 kg formaldehyde scavenger:

Abstract

The invention relates to a formaldehyde scavenging agent. The formaldehyde scavenging agent is prepared from 0.1-1.0% of edible gelatine, 1-5% of amino acid mixture, 1-3% of lemon extract, 1-3% of rose extract, 1-3% of chrysanthemum extract, 0.1-0.5% of phosphate mixture and the balance of water. The invention further relates to the preparation method of the formaldehyde scavenging agent. The method comprises the steps that the raw materials are weighed according to the weight ratio and added into a reaction still, and the mixture is stirred to be dissolved and then subjected to standing. Therecipe of the formaldehyde scavenging agent is all food-level raw materials, the pH value is between 6.5 and 8.5, the formaldehyde scavenging agent cause no harm to the surface of furniture, and no secondary pollution is generated. In addition, the formaldehyde scavenging agent can rapidly react with formaldehyde at the room temperature, and the effective scavenging rate can reach 80% or above. Odor can be rapidly covered and eliminated. The reaction product is soluble in water, can be removed by wiping with a wet towel, and is easy to clean.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a formaldehyde scavenger which is green and odor-cleaning and is mainly used indoors. Background technique [0002] As a solvent with strong adhesion, formaldehyde can enhance the hardness of the board, and has the functions of insect repelling and anticorrosion, so it is widely used in furniture and decoration materials. With the further improvement of people's living standards, the application of interior decoration materials is increasing day by day, and the phenomenon of excessive formaldehyde concentration in indoor air is very common, which poses a serious threat to the health of residents. After toxicological analysis, it is determined that formaldehyde is a highly toxic protoplasmic substance that can damage the DNA in cells, lead to non-programmed DNA synthesis in cells, cause gene mutations in cells, and have a strong carcinogenic effect on animals....
