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
The present invention relates to chemical technology field, be specifically related to a kind of formaldehyde scavenger.
Background technology
Interior decoration needs a large amount of artificial boards, and produce Lauxite that these artificial boards need to be take formaldehyde as Main Ingredients and Appearance as binding agent, because Lauxite is unstable, formaldehyde wherein can discharge from ornament materials continuously, the severe contamination room air.Investigation shows that newly-decorated house concentration of formaldehyde generally exceeds standard, and what have reaches more than 40 times.And studies show that in a large number, the formaldehyde of low dosage can cause breathing problem, and the formaldehyde of high concentration can destroy nerve system of human body, respiratory system, immune system, cause the deformity of these systems, cause canceration, so formaldehyde is genuine " room killer ", health hazard to the mankind is very large, present some formaldehyde scavenger elimination efficiencies on the market are low, although the removing effect that has is better, easily secondary pollution caused in the room.
Summary of the invention
The invention provides a kind of formaldehyde scavenger, it has can stop the advantage that formaldehyde discharges, cost is low, effect is fast from sheet material.
For achieving the above object, the present invention adopts following technical scheme:
A kind of preparation method of methyl alcohol scavenger is characterized in that may further comprise the steps:
(1). the chitosan of weight ratio 0.4-0.6% is added in the aqueous solution, 25 ℃ of lower stirrings 3-4 hour, obtain chitosan solution;
(2). the wax stoste of weight ratio 50% is put into the chitosan solution of step (1), and 25 ℃ of temperature stirred 5-10 minute, this moment the water-soluble cured solution color that is translucent;
(3). the Tea Polyphenols of weight ratio 5% is put into the water-soluble cured solution of step (2), stir, obtain Tea Polyphenols solution;
(4). loading amount is put into water than 50% wormwood heat, heating-up temperature is 65-75 ℃, continues 30 minutes, obtains wormwood solution, and the wormwood elite of obtaining when temperature is lower than 65 ℃ seldom can be destroyed the activity of wormwood elite when being higher than 75 ℃;
(5). from camphortree leaf, extract camphor;
(6) wormwood solution of obtaining in the step (4), (5) and camphor are added in the Tea Polyphenols solution in the step (3) with 5% ratio, stirred 5-10 minute, temperature is 25 ℃, acquisition wormwood camphor mixed liquor;
(7) with weight ratio be 5 ‰ TiO
2Be mixed with in the wormwood camphor mixed liquor in the adding step (6), obtain a kind of formaldehyde scavenger this moment; TiO2 by optical excitation after, capable of purifying air, deodorizing, decomposing organic matter also have higher antibacterial characteristics simultaneously.
Preferably, the weight ratio of chitosan is 0.5% in the step (1).
Preferably, in the step (2) wax stoste being put into chitosan solution mixing time is 5-10 minute, and temperature is 25 ℃.
Preferably, the weight ratio of Tea Polyphenols is 5% in the step (3).
Preferably, the wormwood solution that adds in the step (6) and the weight ratio of camphor are respectively 5%.
Preferably, TiO in the step (7)
2Weight ratio be 5 ‰.
Advantage of the present invention: it has can stop the advantage that formaldehyde discharges, cost is low, effect is fast from sheet material.
The specific embodiment
A kind of preparation method of methyl alcohol scavenger is characterized in that may further comprise the steps:
