Problems solved by technology

A large number of studies have shown that low-dose formaldehyde can cause respiratory diseases, while high-concentration formaldehyde can damage the human nervous system, respiratory system, and immune system, causing deformities in these systems and causing cancer. Therefore, formaldehyde is a veritable "room killer". It is very harmful to human health. At present, some formaldehyde scavengers on the market have low removal efficiency. Although some have better removal effect, they are easy to cause secondary pollution to the living room.

Embodiment Construction

[0019] A kind of preparation method of methanol scavenger is characterized in that comprising the following steps:

[0020] (1). Add chitosan with a weight ratio of 0.4-0.6% to the aqueous solution, and stir at 25°C for 3-4 hours to obtain a chitosan solution;

[0021] (2). Put the wax stock solution with a weight ratio of 50% into the chitosan solution in step (1), at a temperature of 25° C., and stir for 5-10 minutes. At this time, the water-soluble wax solution is translucent;

[0022] (3). Tea polyphenols with a weight ratio of 5% are put into the water-soluble wax solution in step (2), and stirred evenly to obtain a tea polyphenols solution;

[0023] (4). Put the wormwood with a loading ratio of 50% into water and heat it at 65-75° C. for 30 minutes to obtain a wormwood solution;

[0024] (5). Camphor is extracted from camphor leaves;

[0025] (6) Add the wormwood solution and camphor obtained in steps (4) and (5) to the tea polyphenol solution in step (3) in a ratio of...

Abstract

The invention discloses a preparation method for a formaldehyde scavenging agent. The preparation method comprises the following steps: (1) preparing a chitosan solution; (2) placing a wax stock solution into the chitosan solution obtained in the step (1) to obtain a water-soluble wax solution; (3) placing tea polyphenol into the water-soluble wax solution obtained in the step (2) to obtain a tea polyphenol solution; (4) placing wormwood into water, and heating to obtain a wormwood solution; (5) extracting camphor from camphor leaves; (6) adding the wormwood solution obtained in the step (4) and the camphor obtained in the step (5) into the tea polyphenol solution obtained in the step (3) to obtain a wormwood and camphor mixed solution; and (7) adding TiO2 into the wormwood and camphor mixed solution obtained in the step (6) to obtain the formaldehyde scavenging agent. The formaldehyde scavenging agent has the advantages of capability of preventing formaldehyde from being released from plates, low cost and quick effect.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a formaldehyde scavenger. Background technique [0002] Indoor decoration requires a large number of artificial panels, and the production of these artificial panels requires formaldehyde-based urea-formaldehyde resin as a binder. Because the urea-formaldehyde resin is unstable, the formaldehyde in it will be continuously released from the decorative materials, seriously polluting the interior. Air. Surveys show that the concentration of formaldehyde in newly renovated houses generally exceeds the standard, and some are as high as forty times. A large number of studies have shown that low-dose formaldehyde can cause respiratory diseases, while high-concentration formaldehyde can damage the human nervous system, respiratory system, and immune system, causing deformities in these systems and causing cancer. Therefore, formaldehyde is a veritable "room killer". It is ver...
