Description
Technical field
The present invention relates to a kind of house ornamentation care product, in particular to a kind of ordor removing removes aldehyde wall paper care agent and its preparation side
Method.
Background technique
In recent years, people started to be keen to using wall paper wallpaper is pasted, to replace latex paint material to carry out beautiful dress to metope
Decorations.Especially wall paper is decorated, not only bright in luster, and pattern enriches, has texture, and material is environmentally friendly, easy for construction.However, wall
After a certain period of use time, the vividness of color can gradually decline cloth, and after being contacted for a long time, surface also will receive mill
Damage, it is therefore desirable to after pasting wall paper, increase by one of working procedure to protect wall paper surface and increase the service life of wall paper.
In addition, the fast development in market, also causes some fitment material for family qualities very different, it can a large amount of, sustained release in poor material
Noxious material, such as formaldehyde, TVOC, benzene homologues, Ammonia, radon etc., most of substance has been identified as carcinogenic substance and mutagen,
It is the injury of zero distance to human body.
Formaldehyde has strong and stimulating to human body mucous membrane, especially respiratory system.Once plate product burst size of methanal is exceeded,
The free formaldehyde that will cause after fitting up in Indoor Air is exceeded, reduces immune function of human body, causes a variety of diseases, long-term to suck
A small amount of formaldehyde can also cause slow poisoning.So how avoiding Form aldehyde release, thoroughly removing formaldehyde, just have to continue in formaldehyde
During volatilization, these pernicious gases are carried out with lasting improvement.At present except the active charcoal of aldehyde major technique removes aldehyde, photocatalyst
Except aldehyde, biological enzyme are except aldehyde etc..Photocatalyst is ultraviolet light catalyst, under action of ultraviolet radiation, by Formaldehyde decomposition at carbon dioxide and
Water.Acceptance is very high at home for current all kinds of photocatalyst products, and moderate, except aldehyde timeliness is long.Biological enzyme is to adopt except aldehyde
Formaldehyde is removed with physical absorption+biological decomposition method.The formaldehyde molecule in air is first subjected to capture absorption, recycles and absorbs
Biological enzyme in medium volatilizees Formaldehyde decomposition at carbon dioxide and water, and formaldehyde in medium can be made to be constantly in undersaturated condition.
108299956 A of CN discloses a kind of except aldehyde ordor removing sealer and preparation method.Aldehyde ordor removing sealer should be removed, was pressed
Mass percent meter, comprising 4~20% water soluble chitosan, 0.1~5% nano-negative ion, 0.5~5% benzene homologues
Catabolic enzyme, 0.5~5% ester catabolic enzyme, Formaldehyde decomposition enzyme of 0 .5~5% etc..Product safety environmental protection, to indoor pollution sky
The good purification of gas, clean-up effect is lasting, sprayable in substrates such as furniture, wallpaper, abatvoix, carpet, floors, adsorbs and divides
Solve the polluted gas such as formaldehyde, the TVOC in air.107694325 A of CN disclose a kind of special efficacy biological enzyme except aldehyde air cleaning agent and
Preparation method.Aldehyde air cleaning agent should be removed, being grouped as by mass percentage is 2~6% laccases, 0.5~2% formaldehyde dehydrogenase, pectin
Enzyme 2~5%, 0.1~0.2% along the double dehydrogenases of benzene dihydro, 0.1~0 .5% epoxide hydrolase, 1~2% stabilizer, 10~
15% plant extract agent etc..The product is sprayable in the house ornamentations substrate such as furniture, wallpaper, leather, carpet, floor, curtain, decomposes empty
The polluted gas such as formaldehyde, ammonia, TVOC in gas.Currently, there are no the products of special care wall paper in the market, while also can be net
Change room air.
