Embodiment 1

[0022] Present embodiment provides a kind of formaldehyde scavenger, and it is made up of following components by weight percentage:

[0023] 60% by weight sodium sulfate-hydrogen peroxide-sodium chloride adduct;

[0024] 1% formaldehyde scavenging agent by weight percentage;

[0025] 8% bentonite by weight;

[0026] 20% by weight of water;

[0027] 0.5% tea polyphenols by weight;

[0028] 1% cetyltrimethylammonium bromide by weight;

[0029] 3% amino acid by weight.

[0030] In this example, the sodium sulfate-hydrogen peroxide-sodium chloride adduct is prepared by the following method: adding sodium chloride to the hydrogen peroxide solution, then adding anhydrous sodium sulfate, mixing evenly, and ultrasonically stirring , suction filtration under reduced pressure, and vacuum drying to obtain sodium sulfate-hydrogen peroxide-sodium chloride adduct.

[0031] In this embodiment, the formaldehyde absorbing agent is selected from BL-formaldehyde absorbing agent.

Abstract

The invention relates to the technical field of formaldehyde removal, in particular to a formaldehyde scavenger. The formaldehyde scavenger comprises the following components of, by weight, 60-65% ofsodium sulfate- hydrogen peroxide- sodium chloride adduct, 1-5% of a formaldehyde absorptive reagent, 8-15% of bentonite, 20-50% of water, 0.5-4% of tea polyphenol, 1-3% of hexadecyl trimethyl ammonium bromide and 3-8% of amino acid. According to the formaldehyde scavenger, formaldehyde pollutants can be very effectively removed, the living space can be purified, and the formaldehyde scavenger adopting the formula can be prepared after repeated and in-depth experimental research of the applicant, the aldehyde removal rate of the formaldehyde scavenger can reach over 90% and is higher than thealdehyde removal rate of similar products in the market, and the applicant pays a lot of efforts to the formaldehyde scavenger.

Description

technical field [0001] The invention relates to the technical field of formaldehyde removal, in particular to a formaldehyde scavenger. Background technique [0002] Formaldehyde is one of the most serious indoor organic gas pollutants and has very high toxicity. In June 2004, a report published by the International Cancer Research Center (IARC) of the World Health Organization stated that high concentrations of formaldehyde can cause ear, nose and throat cancer and For other physical diseases, on the list of priority control of toxic chemicals in my country, the first is dioxin, and the second is formaldehyde. Therefore, formaldehyde is extremely harmful to human health. [0003] Nowadays, it is more and more common for people to decorate offices, conference rooms and living rooms, etc., and the requirements for airtightness of the space are getting higher and higher, which makes the exchange of indoor and outdoor air less and less. When the national health, construction an...
