Description

Technical Field

[0001] The invention relates to the technical field of purifiers, and in particular to a plant composite purifier capable of removing formaldehyde and odor and a preparation method thereof. Background Art

[0002] With the development of economy and the continuous improvement of people's living standards, interior decoration is becoming more and more luxurious, and indoor air pollution is becoming more and more serious. Among them, formaldehyde is one of the most serious sources of pollution, which poses a great threat to human health, especially children and the elderly who stay in indoor environments for a long time.

[0003] Formaldehyde is one of the most toxic substances among the many volatile organic compounds in furniture. Formaldehyde gas is highly irritating. It is a protoplasmic toxic substance that can bind to proteins in the blood and cells and react with amino groups to form formylated proteins. Formaldehyde can directly irritate the skin and epidermal cells, causing necrosis, pigmentation, and skin inflammation. Long-term exposure to low concentrations of formaldehyde can cause lesions such as nasopharyngeal cancer and hematopoietic dysfunction. Among indoor gas pollutants, formaldehyde has the widest source, the most serious concentration exceeding the standard, and the greatest threat to human health. Therefore, methods that can control the concentration of formaldehyde gas within a safe range or remove it are of great significance to environmental protection and human health.

[0004] Therefore, a plant composite purifier capable of removing formaldehyde and odor and a preparation method thereof are proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the problem of formaldehyde causing harm to the human body. The present invention provides a plant composite purifier capable of removing both formaldehyde and odor and a preparation method thereof.

[0006] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0007] A plant composite purifier capable of removing formaldehyde and odor, mainly comprising the following raw materials in parts by weight: 0.3%-0.5% terpineol, 7.9%-8.7% chitin, 6.2%-7.9% plant tannin, 0.8%-1.3% cellulose, 0.7%-1.2% chitosan, 0.6%-0.9% mineral ions, 0.2%-0.5% azone, 79.0%-83.3% RO pure water, wherein the total weight of the raw materials is 100%;

[0008] The terpineol is prepared by precipitating hydrated terpene diol crystals from pinene in turpentine oil under the action of 30% sulfuric acid, dehydrating the terpineol under the catalysis of 0.2% sulfuric acid, separating the terpineol into crude alcohol by layers, and distilling under reduced pressure.

[0009] The plant tannin is extracted from any one of the leaves, fruits, roots and barks of natural plants. Plant tannin is a natural product with a polyphenol structure. It is widely present in the leaves, fruits, roots and barks of natural plants and is an important natural polyphenol active substance. A large amount of polyphenol active substances are produced by hydrolysis through advanced technology and process, which act on the surface of odorous substances, penetrate the inner wall through product adsorption, continuously realize permanent bonding of odor molecules, and react with odor molecules by nucleophilic addition. The generated product is safe, non-toxic and stable in nature. Because the green extract will not volatilize and cause secondary pollution, continuous and thorough deodorization is achieved at the source of odor release.

[0010] The chitosan is obtained by deacetylation of chitin which is widely present in nature.

[0011] The chitin is taken from any one of the shells of crustaceans and insects, and can quickly undergo adsorption, coupling polymerization and catalytic reaction with formaldehyde at room temperature and under visible light, thereby reducing and removing the content of free formaldehyde and bound formaldehyde in the pollution source, and efficiently and quickly reducing and removing formaldehyde from the source. Through its strong penetration ability, absorption factor and efficient catalytic decomposition, formaldehyde is converted into a stable polymer that is non-toxic and harmless to the human body and decomposed in a long-term catalytic manner, solving the sick building syndrome that occurs in indoor public facilities and personal houses.

[0012] The preparation method of the plant composite purifier capable of removing both formaldehyde and odor is as follows:

[0013] S1: 83.3% of RO pure water is added into a sealed mixing tank, and 0.5% of pineneol, 6.55% of chitin, 5.75% of plant tannin, 1.3% of cellulose, 1.2% of chitosan, 0.9% of mineral ions and 0.5% of azone are weighed in sequence and added into the sealed mixing tank one by one, stirring while adding, and stirring is continued for 3 minutes after adding;

[0014] S2: Pour the mixed liquid in the sealed mixing tank into the large mixing tank and stir at high speed for 5 minutes. After mixing evenly, carry out actual tests and laboratory tests respectively. After passing the tests, canning is carried out. During canning, stir while canning. After packaging, the product is obtained.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The main ingredients of the product of the present invention are derived from natural chitin + plant tannin, which is safe, environmentally friendly and healthy. The product is safe, non-toxic and non-corrosive, non-conjunctival closed, non-odor masking, and is of the permeation degradation type. It is maternal and infant grade. This product and its decomposition products have no harm to sensitive infants and young children, and there is no secondary pollution. Even in the high temperature and high humidity environment in summer, the formaldehyde removal and deodorization effects are efficient, strong, safe, thorough, and long-lasting without rebound. Customers have a good experience with the formaldehyde removal and deodorization effects and are highly satisfied and recognized.

[0017] 2. The main component of the present invention, natural extract chitin, has the function of removing formaldehyde: it can quickly undergo adsorption coupling polymerization and catalytic reaction with formaldehyde at room temperature and under visible light, reduce and remove the content of free formaldehyde and bound formaldehyde in the pollution source, and efficiently and quickly reduce and remove formaldehyde from the source. Through its strong penetration ability, absorption factor and efficient catalytic decomposition, formaldehyde is converted into a stable polymer that is non-toxic and harmless to the human body and decomposes it in a long-term catalytic manner, solving the sick building syndrome that occurs in indoor public facilities and personal houses.

[0018] 3. The deodorizing function of the main ingredient of the present invention, plant tannin: plant tannin is a natural product with a polyphenol structure. It is widely found in leaves, fruits, roots and bark of natural plants and is an important natural polyphenol active substance. A large amount of polyphenol active substances are produced by hydrolysis through advanced technology and process, which act on the surface of odorous substances, penetrate the inner wall through product adsorption, and continuously achieve permanent bonding of odor molecules, and undergo nucleophilic addition reaction with odor molecules. The generated products are safe, non-toxic and stable in nature. Because the green extract will not volatilize and cause secondary pollution, continuous and thorough deodorization is achieved at the source of odor release. DETAILED DESCRIPTION
