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.

Description

A kind of preparation method except formaldehyde spray and spray thereof

Technical field

The present invention relates to environmental technology field, particularly relate to a kind of preparation method and the spray thereof that can remove the spray of formaldehyde.

Background technology

Current finishing pollution more and more becomes the thing of puzzlement people, the No.1 of finishing pollution is exactly formaldehyde, formaldehyde is a kind of strong carcinogen, therefore people move heaven and earth to removal formaldehyde at present, current removal formaldehyde mainly contains several method, and one is adopt chemical spray and formolite reaction to remove formaldehyde, and the benefit of this mode is that clearance is high, but shortcoming is also obvious, be exactly while formaldehyde is removed because the use of chemical spray comes again with new pollution; Another be adopt charcoal absorption, this minimizing technology be a little safety, can not secondary pollution be brought, but shortcoming is also obvious: clearance is low, and removal effect is bad.

Summary of the invention

The object of the present invention is to provide one to remove formaldehyde spray, this spray does not adopt chemical spray, has except formaldehyde clearance is high, speed fast, does not have secondary pollution problems.

For achieving the above object, the present invention adopts following technical scheme:

Except a preparation method for formaldehyde spray, comprise the steps:

1) dandelion, Radix Isatidis and cordate houttuynia are pulverized by micronizer after 1:1:1 mixing, after crossing 80 orders solarizations, get the mixed material powder of 300g:

2) the ethanol 2500ml of 95% will be added in above-mentioned mixed material powder, at 25 DEG C, leave standstill 10h, then carry out refluxing extraction 22h at 80 DEG C, obtain extract;

3) said extracted liquid being put into centrifuge carries out centrifugal with 2500r/min, gets supernatant;

4) by the filtering with microporous membrane of supernatant by 0.45um;

5) above-mentioned filtered fluid is obtained A stoste after decompression distillation recovery ethanol;

6) 40 order sizes are ground into after Radix Glycyrrhizae 125g, tarragon 125g and dried orange peel 150g being mixed;

7) add 3000ml distilled water by the crushed material in step 6, soak after 4 hours and carry out steam distillation extraction volatile oil, the volatile oil obtained is B stoste;

8) A stoste and B stoste are mixed with the volume ratio of 1:1.5;

9) add Mint Essence in the ratio of 2ml/500ml in liquid upon mixing, add Tween 80 in the ratio of 1ml/500ml, can obtain after mixing except formaldehyde spray.

The principle that spray of the present invention removes formaldehyde utilizes the poly-aldehydes matter and formolite reaction that extract in plant, the record adopting plant to remove formaldehyde is recorded in prior art, but clearance is the highest 90%, applicant is by research and great many of experiments, determine six best Plants sources and best mixed proportion, by the technique of uniqueness of the present invention, the clearance of formaldehyde can be brought up to more than 97%, there is the technique effect removing formaldehyde fast simultaneously, the formaldehyde rate of going of 2 hours just can reach 68%, and these are all do not reach in prior art.

Of the present invention to have formaldehyde clearance high, and it is fast that formaldehyde removes speed, can not produce the advantages such as secondary pollution in the process of removal.

Detailed description of the invention

Below in conjunction with embodiment, the present invention will be further described:

Embodiment 1

Formaldehyde spray is removed in preparation, comprising:

1) dandelion, Radix Isatidis and cordate houttuynia are pulverized by micronizer after 1:1:1 mixing, after crossing 80 orders solarizations, get the mixed material powder of 300g:

2) the ethanol 2500ml of 95% will be added in the material powder after above-mentioned co-grinding, at 25 DEG C, leave standstill 10h, then carry out refluxing extraction 22h at 80 DEG C, obtain extract;

3) said extracted liquid being put into centrifuge carries out centrifugal with 2500r/min, gets supernatant;

4) by the filtering with microporous membrane of supernatant by 0.45um;

5) above-mentioned filtered fluid is obtained A stoste after decompression distillation recovery ethanol;

6) 40 order sizes are ground into after Radix Glycyrrhizae 125g, tarragon 125g and dried orange peel 150g being mixed;

7) add 3000ml distilled water by the crushed material in step 6, soak after 4 hours and carry out steam distillation extraction volatile oil, the volatile oil obtained is B stoste;

8) A stoste and B stoste are mixed with the volume ratio of 1:1.5;

9) add Mint Essence in the ratio of 2ml/500ml in liquid upon mixing, add Tween 80 in the ratio of 1ml/500ml, after stirring, formaldehyde spray can be obtained

In order to verify the effect of this deodorant, adopting and verifying as follows:

Purchase the sheet material of same batch of the same specification of commercially available same company, be made into the square casing of five 1m3, five casings are airtight separately, are only provided with a sample tap.

Five casings are labeled as 1# casing, 2# casing, 3# casing, 4# casing and 5# casing respectively.

Test method:

1) test the initial concentration of formaldehyde in five casings respectively, be designated as Z1, method of testing is GB/T15516-1995 " air quality-formaldehyde determination acetylacetone,2,4-pentanedione AAS ".

2) formalin of 30% concentration of equivalent will be sprayed in five casings respectively and airtight maintenance 24 hours, and then test concentration of formaldehyde, be designated as Z2.

3) then the A stoste of 10ml will be sprayed in 2# casing, the B stoste of 10ml will be sprayed in 3# casing, A and the B stoste that 10ml mixes with 1:1 ratio is sprayed in 4# casing, spray into 10ml spray of the present invention in 5# casing, then survey concentration of formaldehyde after 2 hours, be designated as Z3, and then every test in a 4 hours concentration of formaldehyde, be designated as Z4, again test concentration of formaldehyde after six hours, be designated as Z5.Result of the test is as following table:

	Z1(mg/m 3)	Z2(mg/m 3)	Z3(mg/m 3)	Z4(mg/m 3)	Z5(mg/m 3)	2h clearance	12h clearance
								1#	0.095	0.943	0.895	0.854	0.768	5％	18.5％
2#	0.089	0.961	0.637	0.429	0.354	33.7％	63.1％
								3#	0.093	0.952	0.589	0.456	0.302	38.1％	68.2％
4#	0.082	0.937	0.477	0.110	0.09	49.1％	90.3％
								5#	0.095	0.948	0.301	0.096	0.032	68.2％	97.1％

Data from table, be described as follows: under normal circumstances when not spraying any spray, formaldehyde Natural Attenuation can have the clearance of 18.5%, spraying A stoste or B stoste all only have the clearance of about 60%, A:B component can significantly improve with clearance after 1:1 mixing, can 90% be reached, but applicant finds after great many of experiments, by A:B component with after the mixing of 1:1.5 ratio, except 12 clearances can be brought up to except 97% significantly from 90%, also find that there is following technique effect: removing speed significantly increases, at spray of the present invention, just can 68.2% be reached at the clearances of first four hours.Therefore, it is fast that spray of the present invention has formaldehyde speed, clearance advantages of higher.

It will be recognized by those skilled in the art, under the prerequisite not departing from protection scope of the present invention, various amendment, change and combination can be carried out to above-mentioned embodiment, and think that this amendment, change and combination are within the scope of originality thought.
