Problems solved by technology

After a large number of tests, it was found that the common formaldehyde removal methods rarely have long-term significant effects on the volatilization of formaldehyde from wood-based panels, etc. It is extremely urgent to develop a formaldehyde scavenger with long-term effects to solve the problem of indoor formaldehyde pollution

Embodiment 1

[0014] Embodiment 1: a kind of formaldehyde scavenging agent for board its raw materials are calculated by weight: 15 parts of nanometer antibacterial agent, 12 parts of fatty alcohol polyoxyethylene ether, sodium sulfate-hydrogen peroxide-sodium chloride adduct 7 parts, 5 parts of tea extract, 10 parts of modified polyacrylamide solution, 5 parts of urea, 3 parts of thiourea, 1.5 parts of defoamer, and 200 parts of deionized water.

[0015] The preparation process of the sodium sulfate-hydrogen peroxide-sodium chloride adduct is as follows: sodium chloride is added to the hydrogen peroxide solution, then anhydrous sodium sulfate is added, stirred, vacuum filtered, and vacuum-dried to obtain sulfuric acid Sodium-hydrogen peroxide-sodium chloride adduct.

[0016] The nano-antibacterial agent is a mixture of nano-TiO2, nano-ZnO and nano-Ag. The particle size of nano-TiO2, nano-ZnO and nano-silver is 30-50 nanometers, and the ratio of the three is TiO2:ZnO:Ag=1.5:1 : 0.5.

Abstract

The invention relates to the field of indoor environmental protection, in particular to a formaldehyde scavenger for boards. The formaldehyde scavenger is composed of, by weight, 15 parts of nanometer antibacterial agents, 12 parts of fatty alcohol-polyoxyethylene ether, 7 parts of sodium sulfate- hydrogen peroxide- sodium chloride adducts, 5 parts of tea extracts, 10 parts of modified polyacrylamide solutions, 5 parts of urea, 3 parts of thiourea, 1.5 parts of defoaming agents and 200 parts of deionized water. The formaldehyde scavenger can be directly applied to the surfaces of decorative materials or polymeric boards, can effectively reduce the content of toxic and harmful substances such as formaldehyde at home and can improve the air quality of homes.

Description

technical field [0001] The invention relates to the field of indoor environmental protection, in particular to a formaldehyde scavenger for boards. 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. Among them, artificial panels have become the most stubborn and highly harmful pollution source among indoor pollutants due to their huge volati...
