Abstract
The invention discloses a kind of formaldehyde scavengers and preparation method thereof, consist of the following compositions: 15% remover, the Kathon CG of 0.07-0.12%, the nonylphenol polyoxyethylene ether of 0.17-0.22%, 2.7-3.2% trisodium citrate monocalcium salt to close object, the thiocarbamide of 0.7-1.2%, surplus be water to 100%.By the proposition formula of this programme and the formaldehyde scavenger of preparation method preparation, formaldehyde removing rate can be greatly increased, and furniture surface will not be made phenomena such as being bubbled, crackle occur, while will not cause to corrode to the metal in furniture.
Description
Technical field
The present invention relates to formaldehyde removing technical fields more particularly to a kind of formaldehyde scavenger and preparation method thereof.
Background technique
Formaldehyde, colourless irritant smell, chemical formula HCHO or CH2O, molecular weight 30.03, also known as formaldehyde are colourless, to people
The irritating effect such as eye, nose.On October 27th, 2017, the carcinogenic substance inventory that international cancer research institution, the World Health Organization announces
In, formaldehyde is placed in a kind of carcinogenic substance list, the formaldehyde caused harm to the human body in life, it may be said that it is ubiquitous, wherein
Furniture and timber floor are the main source of formaldehyde.
The product for removing formaldehyde, i.e. formaldehyde scavenger exists in the prior art, existing formaldehyde scavenger is using
Process have the disadvantages that the formaldehyde removing effect of formaldehyde scavenger is poor, especially using after the time of one end, removal
Effect has apparent reduction, while brushing in furniture plate surface, is easy that furniture is made phenomena such as being bubbled, crackle occur, and
Cause furniture surface that certain viscosity is presented, is easy absorption dust, furthermore can also cause corruption to metals such as hinges in furniture
Erosion, it is therefore desirable to which existing formaldehyde scavenger is improved.
Summary of the invention
The purpose of the present invention is to solve disadvantage existing in the prior art, and a kind of formaldehyde scavenger that proposes and its
Preparation method.
To achieve the goals above, present invention employs following technical solutions:
A kind of formaldehyde scavenger, consists of the following compositions:
Surplus is water to 100%.
Preferably, the remover includes urea, imidazolidinone, any one or more group in adipic dihydrazide
It closes.
A kind of preparation method of formaldehyde scavenger, the described method comprises the following steps:
Step (1): reaction kettle is added in remover and water, temperature is controlled at 60-65 DEG C, held to dissolving by heating stirring
It is heating stirring 30-40 minutes continuous；
Step (2): nonylphenol polyoxyethylene ether is added into the solution of step (1), is uniformly mixed, temperature is controlled
At 60-65 DEG C, continuous heating is stirred 5-10 minutes；
Step (3): trisodium citrate monocalcium salt is added into the solution of step (2) and closes object, the pH value of solution is adjusted
Section makes the control of its pH value in 7-7.5, thiocarbamide is then added, is uniformly mixed, and keeps 60-65 DEG C of heating temperature, and continuous heating
Stirring 5-10 minutes；
Step (4): Kathon CG finally is added into the solution of step (3), stirs evenly, temperature is then reduced to 45-50
DEG C, heating after five minutes, stops heating, and be cooled to room temperature, formaldehyde scavenger can be obtained.
Compared with the prior art, the beneficial effects of the present invention are:
1, phenomena such as not corroding metal, being not in the visible rust spot of naked eyes, be bubbled.
2, the change such as macroscopic color will not be caused to change, while bubblings, crackle will not occur on the surface of furniture
Change.
3, formaldehyde removal rate is detected according to GB/T17657-2013, can reach 90% or more.
4, it is tacky not serious to be sprayed on the surfaces such as floor, furniture, fabrics, leather hair oil, Yi Baojie.
In conclusion first can be greatly increased by this programme formula proposed and the formaldehyde scavenger of preparation method preparation
Aldehyde removal rate, and furniture surface will not be made phenomena such as being bubbled, crackle occur, while will not cause to the metal in furniture
Corrosion.
Specific embodiment
A kind of formaldehyde scavenger, consists of the following compositions:
Surplus is water to 100%.
The remover includes urea, imidazolidinone, any one or more combination in adipic dihydrazide.
The remover can be specially the ingredient of following several forms:
A kind of preparation method of formaldehyde scavenger, method the following steps are included:
Step (1): reaction kettle is added in remover and water, temperature is controlled at 60-65 DEG C, held to dissolving by heating stirring
It is heating stirring 30-40 minutes continuous；
Step (2): nonylphenol polyoxyethylene ether is added into the solution of step (1), is uniformly mixed, temperature is controlled
At 60-65 DEG C, continuous heating is stirred 5-10 minutes；
Step (3): trisodium citrate monocalcium salt is added into the solution of step (2) and closes object, the pH value of solution is adjusted
Section makes the control of its pH value in 7-7.5, thiocarbamide is then added, is uniformly mixed, and keeps 60-65 DEG C of heating temperature, and continuous heating
Stirring 5-10 minutes；
Step (4): Kathon CG finally is added into the solution of step (3), stirs evenly, temperature is then reduced to 45-50
DEG C, heating after five minutes, stops heating, and be cooled to room temperature, formaldehyde scavenger can be obtained.
In order to verify the effect of this programme formaldehyde scavenger, using GB/T17657-2013 " wood-based plate and facing physics and chemistry
Energy test method " 4.59 condensed steam waters, carry out the test of formaldehyde removal rate.
Five kinds of common artificial boards are bought from market first, are density board, particle board, multi-layer board, lumber core, solid wood respectively
Finger-jointed plate sufficiently verifies this programme formaldehyde scavenger and removes effect of formaldehyde to various plates.
Then by the rectangle sample of five kinds of plate interceptions same size size (150x50mm), amount to five groups, every group by five
Each one piece of composition of kind plate, one group is blank control, in addition one group of formaldehyde scavenger using this programme uses city for three groups respectively
Three kinds on field are gone formaldehyde products, and following table one and table two are obtained after interpretation of records:
Table one
Table two
Remarks: formaldehyde removal rate=(plate burst size of methanal after same period blank sample burst size of methanal-processing)/same period blank
Sample burst size of methanal * 100%.
Formaldehyde removal rate compares after handling plate by various products, and the formaldehyde scavenger of this programme is after spraying 24 hours
Formaldehyde removal rate can reach 50.92%, and highest 98.00% is reached after 7 days, still reaches within 180 days 91.01%, existing product A exists
90 days removal rates fall sharply to after 30.70%, 180 day only 4.14%, illustrate that there are effects not to continue bounce problem；Existing product
B removal rate 59.89% after 7 days, stable but removal rate relatively stable in 59% or so product be not high ever since；Existing product
The unobvious inefficient fruit of C removal rate is the product of inferior quality.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
