Abstract

The invention relates to the field of air purification, in particular to an anion formaldehyde purifying agent. The anion formaldehyde purifying agent comprises, by weight, 5-10 parts of anometer negative ion powder, 4-8 parts of a nanometer antibacterial agent, 5-10 parts of modified polyacrylamide, 0.2-0.5 part of a flatting agent, 0.2-0.5 part of rare earth activator, 0.5-2 parts of plant aromatherapy oil, 1-3 parts of tea polyphenol, 1-2.5 parts of defoamer and 200 parts of deionized water. By the arrangement, sterilization and deodorization can be effectively performed, the anometer negative ion powder and the nanometer antibacterial agent which are added can serve as photocatalyst capable of effectively decomposing harmful substances of formaldehyde, benzene and the like in the air, and the nanometer antibacterial agent has the strong antibacterial function; the antibacterial effect within a long period is guaranteed, and in addition, the anometer negative ion powder has the healthcare function.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an anion formaldehyde purifier. 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 purifiers have en...
