Problems solved by technology

Some of the existing formaldehyde scavenger are based on amine compounds such as urea and ethylenediamine as the main components. Although this type of formaldehyde scavenger can significantly remove formaldehyde, excessive use of this type of compound will cause ammonia to pollute again, causing indoor pollution. Ammonia has a strong smell and is not easy to remove, causing secondary pollution

Abstract

The invention discloses a formaldehyde catching agent for indoor air purification, as well as a preparation method and an application of the formaldehyde catching agent. The formaldehyde catching agent comprises the following raw materials in parts by mass: 6-9 parts of stropanthus divericatus, 2-4 parts of wistaria wood, 0.8-1.3 parts of biotin, 3.5-5.2 parts of linoleic acid, 15-19 parts of xylitol, 3-5 parts of xanthate, 2.3-2.7 parts of modified halloysite and 68-85 parts of deionized water. The modified halloysite is prepared by drying and performing superfine grinding on halloysite, adding water for mixing, adding acetic acid for agitation, and adding terbium perchlorate for the agitation. The stropanthus divericatus and the wistaria wood after biotin treatment exert an effect together with the modified halloysite, and the agent has high absorption efficiency of formaldehyde in indoor air, and can remove free formaldehyde in the air, reduce formaldehyde release amount in a decoration product, improve formaldehyde stability in the decoration product and solve the problem of formaldehyde pollution in interior decoration.

Description

technical field [0001] The invention relates to the technical field of pollution, in particular to a formaldehyde scavenger for indoor air purification and its preparation method and application. Background technique [0002] Formaldehyde is a systemic poison, which will reduce the antioxidant capacity of various organs of the body, resulting in oxidative damage to organs, and the higher the concentration, the more serious the damage. Indoor formaldehyde pollution mainly comes from furniture, construction sources, fabrics, wood product fillers, cosmetics, detergents, and personal items. At present, a variety of methods have been adopted at home and abroad to control indoor formaldehyde pollution. These purification technologies are summarized as follows: adsorption technology, photocatalytic technology, negative air ion technology, chemical neutralization technology, ozone oxidation technology, biotechnology, catalytic oxidation at room temperature technology, material clos...
