Abstract

The invention relates to the field of air purification, and particularly relates to a formaldehyde removal purifying agent. The formaldehyde removal purifying agent comprises the following raw materials in parts by weight: 5-10 parts of tea extract, 4-8 parts of nanometer antibacterial agent, 5-10 parts of modified polyacrylamide, 0.2-0.5 part of leveling agent, 0.2-0.5 part of rare earth activating agent, 0.5-2 parts of vegetable aromatherapy essential oil, 1-3 parts of tea polyphenois, 1-2.5 parts of defoaming agent, and 200 parts of deionized water. The formaldehyde removal purifying agent can effectively remove bacteria and odor, formaldehyde, benzene and other harmful substances in air can be effectively decomposed by adding the tea extract and the nanometer antibacterial agent as photocatalyst, and the nanometer antibacterial agent also has strong antibacterial action to guarantee the long-time antibacterial effect.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a purifying agent for removing formaldehyde. Background technique [0002] Formaldehyde pollution is usually the most common and most difficult to deal with in indoor air pollution. In the process of decorating houses, many man-made panels, adhesives, paints, and paints contain formaldehyde, which will volatilize formaldehyde-based pollution for a long time Gas, causing harm to human body. Formaldehyde has been determined by the World Health Organization as a carcinogenic and teratogenic substance. Long-term exposure to formaldehyde can cause chronic respiratory diseases, pregnancy syndrome, leukemia and other diseases. It can also cause chromosomal abnormalities in newborns and adolescents with memory loss and mental retardation. [0003] With the improvement of people's living standards, the requirements for the environment are getting higher and higher. More and more air puri...
