Embodiment 1

[0094] A high-efficiency formaldehyde-removing composition comprises: 2% ethyl acetoacetate, sodium hydroxide, and the balance of water. The preparation method is as follows: adding ethyl acetoacetate and water into a suitable container, stirring to dissolve, adding sodium hydroxide to adjust the pH value to 7-9.

[0095] If long-term storage is required, the above composition can be split into two components according to the ratio: (A) pure ethyl acetoacetate, (B) aqueous solution containing an appropriate amount of sodium hydroxide. A and B are packaged and stored separately, and A and B are mixed according to a preset ratio during use to obtain the above-mentioned formaldehyde-removing composition.

[0096] The composition solution should be used in time to obtain the best formaldehyde removal effect. It is recommended to store at room temperature for no more than 1 month. If the pH value drops after storage, you can add a small amount of sodium hydroxide to increase the pH...

Embodiment 2

[0098] A high-efficiency formaldehyde removal composition comprises: 2% ethyl acetoacetate, 2% glycine, sodium hydroxide, and the rest water. The preparation method is as follows: adding ethyl acetoacetate, glycine and water into a suitable container, stirring and dissolving, adding an appropriate amount of sodium hydroxide, and adjusting the pH value to 6-8.

[0099] If long-term storage is required, the composition can be split into two components according to the ratio: (A) pure ethyl acetoacetate, (B) glycine, sodium hydroxide, and water. A and B are packaged and stored separately, and A and B are mixed according to a preset ratio during use to obtain the above-mentioned formaldehyde-removing composition.

Embodiment 3

[0101] A high-efficiency formaldehyde-removing composition comprises: 1% ethyl acetoacetate, 0.05% fatty alcohol polyoxyethylene ether, sodium carbonate and the rest of water. The preparation method is as follows: adding ethyl acetoacetate, fatty alcohol polyoxyethylene ether and water into a suitable container, stirring and dissolving, adding an appropriate amount of sodium carbonate, and adjusting the pH value to 7-8.

[0102] If long-term storage is required, the composition can be split into two components according to the ratio: (A) pure ethyl acetoacetate, (B) fatty alcohol polyoxyethylene ether, sodium carbonate, and water. A and B are packaged and stored separately, and A and B are mixed according to a preset ratio during use to obtain the above-mentioned formaldehyde-removing composition.

Abstract

The invention discloses an efficient formaldehyde removing composition, and relates to the technical field of environmental protection. The efficient formaldehyde removing composition comprises waterand ethyl acetoacetate, and further comprises copper ions or a pH adjusting agent for adjusting the pH of the formaldehyde removing composition to be greater than or equal to 5. The composition disclosed by the invention has a remarkable formaldehyde removal effect, is safe to people and articles, has simple production process, and can be used for treating formaldehyde pollution problems in plates, furniture, textiles, new decorations and other fields.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to a high-efficiency formaldehyde-removing composition technology. Background technique [0002] Formaldehyde is a colorless, pungent, irritating gas at room temperature. It is mainly harmful to human health through the respiratory route. It is listed as a "known" human carcinogen by the International Agency for Research on Cancer (IARC) and the National Toxicology Program (NTP) of the United States. , can cause human nasopharyngeal carcinoma and sinus carcinoma, myelogenous leukemia. Animal experiments have shown that formaldehyde can cause benign or malignant tumors in multiple species and locations. my country's "GB50325-2010 Code for Control of Indoor Environmental Pollution in Civil Construction Engineering" stipulates that the limit of formaldehyde in indoor environment is 0.08mg / m 3 (Class I) and 0.1mg / m 3 (Class II). [0003] Formaldehyde is a very basic ch...
