Description
Technical field
The present invention relates to formaldehyde treated technical fields, and in particular to one kind is except formaldehyde decorative panel and preparation method thereof.
Background technique
Formaldehyde is more highly toxic substance, is determined as carcinogenic by the World Health Organization and causes deformed material, is generally acknowledged
One of allergen, and potential strong mutagen.Research shows that: formaldehyde has strong carcinogenic and tumor promotion.
Lot of documents is recorded, and influence of the formaldehyde to human health is mainly manifested in allotriosmia, stimulation, allergy, abnormal pulmonary function, liver function
It can exception and immunologic dysfunction etc..Long Term Contact low dosage formaldehyde can cause chronic respiratory disease, cause nasopharyngeal carcinoma,
The gene mutation of colon cancer, brain tumor, paramenia, nucleus, the single-stranded interior commissure of DNA and DNA and protein commissure and inhibition DNA
The reparation of damage, causes neonatal chromosome disorder, leukaemia at pregnancy syndrome, and teenager's memory and intelligence is caused to decline.
With the improvement of living standards, and health perception and environmental consciousness continuous reinforcement, people are to oneself indoor ring
Border growing interest.People carry out interior decoration using the various new materials of such as decorative panel etc mostly, but by urine aldehyde tree
Decorative panel made of rouge glue, phenolic resin glue, melamine-formaldehyde resin adhesive are isobaric becomes interior while beautifying room
The main source of formaldehyde.In production and using the free formaldehyde released in decorative panel, living environment is polluted, damages the strong of people
Health.The reason of wood-based plate release formaldehyde approximately as: (1) unreacted free formaldehyde is remained when resins synthesis；(2) resins synthesis
When, the formaldehyde that reaction generates unstable group has been participated in, can have been released again in hot pressing；(3) it in resins synthesis, inhales
It is attached to the formaldehyde molecule protonated around colloidal particle, can also be released under the action of electrolyte.
Method currently used for methanal removing has absorption method, catalytic oxidation, biological degradation method, plasma technique etc..
These methods respectively have advantage and disadvantage, and the most commonly used is absorption methods, at present the solid based on all kinds of active carbons and its product
Adsorbent, the often adsorbent of a packet or a box, suction-operated face is small, and adsorption time is long and ineffective, use not side
Just, adsorbed material contacts active carbon outer surface first, then enters back into its macropore, mesoporous and micropore, adsorption molecule
It attracts each other between active carbon by Van der Waals force, is adsorbed on adsorbate among active carbon hole, and active carbon is only to non-
The substance of polarity or low pole has stronger suction-operated, and the molecular weight of formaldehyde is low and polarity is extremely strong, is difficult to pass through activity
Charcoal physical removal, and be easy under adsorption saturation and the higher situation of temperature by secondary release.Application No. is
A kind of novel decorative material for removing formaldehyde of CN201810722143.1 (publication date 20181130) and preparation method thereof decorative panel uses
Alkalize plant fiber, the absorption of oyster shell combination titanium dioxide, decomposing formaldehyde, and still, simple titanium dioxide goes photocatalysis
