Formaldehyde scavenging agent and preparation method thereof

Abstract

The invention discloses a formaldehyde scavenging agent and a preparation method thereof. The formaldehyde scavenging agent comprises 15% of a remover, 0.07-0.12% of Kathon, 0.17-0.22% of nonylphenol polyoxyethylene ether, 2.7-3.2% of trisodium citrate dehydrate, 0.7-1.2% of thiourea and the balance water, wherein the sum of the percentages of the materials is 100%. By means of the formula and the formaldehyde scavenging agent prepared through the preparation method, the formaldehyde scavenging can be greatly reduced, the phenomena of bubbling, cracks and the like on the surface of furniture can be avoided, and meanwhile, metal objects in the furniture cannot be corroded.

Description

technical field [0001] The invention relates to the technical field of formaldehyde removal, in particular to a formaldehyde scavenger and a preparation method thereof. Background technique [0002] Formaldehyde, colorless with pungent odor, chemical formula HCHO or CH 2 O, molecular weight 30.03, also known as formic aldehyde, colorless, irritating to human eyes and nose. On October 27, 2017, in the list of carcinogens released by the International Agency for Research on Cancer of the World Health Organization, formaldehyde was placed in the list of first-class carcinogens. Formaldehyde that causes harm to the human body in life can be said to be everywhere, including furniture and Wood floors are the main source of formaldehyde. [0003] In the prior art, there are products for removing formaldehyde, that is, formaldehyde scavengers. The existing formaldehyde scavengers have the following disadvantages in the process of use: the formaldehyde removal effect of the formald...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there are products for removing formaldehyde, that is, formaldehyde scavengers. The existing formaldehyde scavengers have the following disadvantages in the process of use: the formaldehyde removal effect of the formaldehyde scavengers is relatively poor, especially after using for a certain period of time, its The removal effect is significantly reduced. At the same time, when brushing on the surface of furniture panels, it is easy to cause bubbling and cracks in the furniture, and cause the surface of the furniture to show a certain viscosity, which is easy to absorb dust. In addition, it will also damage metals such as hinges in the furniture. Items cause corrosion, so existing formaldehyde scavengers need to be improved
