Problems solved by technology

[0002] At present, decoration pollution has become more and more troublesome to people. The number one pollution from decoration is formaldehyde, which is a strong carcinogen. Therefore, people are trying every means to remove formaldehyde. There are several ways to remove formaldehyde. One is to use The chemical spray and formaldehyde react to remove formaldehyde. The advantage of this method is that the removal rate is high, but the disadvantage is also obvious, that is, the use of chemical spray brings new pollution while removing formaldehyde; the other is to use activated carbon. Adsorption, the advantage of this removal method is that it is safe and will not cause secondary pollution, but the disadvantages are also obvious: the removal rate is low, and the removal effect is not good

Embodiment 1

[0019] Make a formaldehyde-removing spray, including:

[0020] 1) Mix dandelion, Radix isatidis and Houttuynia cordata in a weight ratio of 1:1:1 and pulverize them with a superfine pulverizer. After passing the sun through 80 meshes, take 300g of mixed raw material powder:

[0021] 2) Add 2500ml of 95% ethanol to the raw material powder after mixing and pulverization, let it stand at 25°C for 10h, and then carry out reflux extraction at 80°C for 22h to obtain an extract;

[0022] 3) Put the above extract into a centrifuge to centrifuge at 2500r / min, and take the supernatant;

[0023] 4) filter the supernatant through a 0.45um microporous membrane;

[0024] 5) After the above-mentioned filtrate is reclaimed ethanol through vacuum distillation, A stock solution is obtained;

[0025] 6) Mix 125g of licorice, 125g of mugwort leaves and 150g of dried tangerine peel and crush them into 40 mesh size;

[0026] 7) Add 3000ml of distilled water to the pulverized material in step 6, ...

Abstract

The invention provides a method for preparing a spraying agent for removing formaldehyde. The method comprises the following steps of: mixing dandelion, isatis roots and cordate houttuynia, and extracting by refluxing to obtain an extract; mixing licorice, folium artemisiae argyi and dried orange peels, and extracting by distilling to obtain an essential oil; mixing the extract and the essential oil, and adding an essence and an additive to obtain the spraying agent for removing the formaldehyde. The spraying agent prepared by adopting the method disclosed by the invention can be used for removing the formaldehyde at a high rate and a high speed without causing secondary pollution.
