Intensive permeable artificial plate formaldehyde scavenging agent

Abstract

The invention discloses an intensive permeable artificial plate formaldehyde scavenging agent and belongs to the technical field of indoor air purification agents. The intensive permeable artificial plate formaldehyde scavenging agent specifically comprises a spherical carrier and diethylenetriamine powder reaction agent, wherein the diethylenetriamine powder reaction agent is adhered to the spherical carrier; the spherical carrier is subjected to surface modification with a cationic surfactant. Due to a permeation function of the cationic surfactant, combination with a plate is improved, andthe solidness is improved; secondly, due to a capturing function of the cationic surfactant, gaseous formaldehyde around a plate can be accumulated around the spherical carrier, then the formaldehydecontacts and reacts with diethylenetriamine, after moisture molecules of a generation product are absorbed, an amide compound is gradually settled on the surface of the spherical carrier and is adsorbed and removed through the spherical carrier, and due to synergism of the three components, high formaldehyde removal efficiency and long-lasting actions can be achieved.

Description

technical field [0001] The invention relates to the technical field of indoor air purifiers, in particular to a formaldehyde scavenger for strong permeable man-made boards. Background technique [0002] Artificial board is a board made by adding chemical adhesives to the scraps produced during the processing of wood. There are many types of wood-based panels, commonly used decorative wood-based panels such as particle boards, medium-density boards, blockboards, plywood, and fireproof boards. Because they have their own different characteristics, they are used in different furniture manufacturing fields. Because urea-formaldehyde resin and phenolic resin have the characteristics of low price, corrosion resistance and durability, urea-formaldehyde resin and phenolic resin are used as adhesives to produce artificial boards that have been widely used in interior decoration building materials. However, urea-formaldehyde resin and phenolic resin are used as adhesives. The manufa...

AI Technical Summary

Problems solved by technology

[0003] Existing formaldehyde scavengers are generally sprayed on the surface of artificial boards to form a film, and formaldehyde is purified by physical adsorption technology, negative ion high-voltage electrostatic dust removal technology or room temperature catalytic oxidation method, etc. Physical adsorption technology can only absorb and store harmful substances, but cannot eventually eliminate them. And there are situations such as adsorption saturation and desorption, so the adsorption material must be replaced frequently; negative ion high-voltage electrostatic technology is a physical process that can effectively remove smoke and dust in the air, but it has no obvious effect on the removal of formaldehyde. Secondly, it is expensive and needs to be used. Electricity will generate noise, which is not conducive to large-scale popularization; room temperature catalytic oxidation method has high efficiency in removing formaldehyde, but it will produce secondary pollutants, such as methanol, formic acid, formaldehyde polymer and other toxic substances, and some substances will also adhere to the board First, it affects the quality of the board, and it is usually a reversible reaction. When the formaldehyde concentration is lower than a certain limit, the formaldehyde purification efficiency is significantly affected; secondly, the reaction area of ​​the membrane is limited. Once the membrane fails, the free formaldehyde in the artificial board will still Will be released in large quantities, causing indoor air pollution
