The advantages of composite floor board existing common solid wooden floor board, and the internal stress between timber is effectively had adjusted, timber is improved with season
Section humidity changes and therefore the disadvantage of deflection greatly is liked by consumer.But in the prior art, manufacturing reality
During wood composite floor, due to having used the chemical reagent such as some adhesives, so that solid wooden compound floor contains a large amount of first
Aldehyde.There is aldehyde radical in formaldehyde molecule, is a kind of important Organic Ingredients, is irritative gas colourless, with overpowering odor.Often
A small amount of formaldehyde is sucked, slow poisoning can be caused, mucous hyperemia, skin irritatin disease, allergic dermatitis, nail angling and crisp occurs
Weak, nail matrix finger tip pain etc..Constitutional symptom has headache, out of strength, stomach is received poor, palpitaition, insomnia, weight loss and vegetative nerve disorderly
Disorderly etc..Since technology and material are limited, at present manufacture indoor furniture and fitment process in can not also total ban use contain
The raw material of formaldehyde components can not remove the harm of formaldehyde from source, therefore, efficiently remove with environmental-friendly indoor formaldehyde
Material has a good application prospect.It is used since formaldehyde cannot be limited comprehensively, eliminating and reduce formaldehyde harm is the task of top priority.
Summary of the invention
The object of the present invention is to provide one kind to remove the coating material solidified coating timber floor of aldehyde UV.
According to an aspect of the invention, there is provided a kind of remove the coating material solidified coating timber floor of aldehyde UV, external coating two
It is secondary except aldehyde UV it is coating material solidified, by weight, except aldehyde UV it is coating material solidified in containing 3%~20% modification fumed silica and
5%~10% remove aldehyde auxiliary agent；
Wherein, modified gas phase sio2 passes through silane or siloxanes by halosilanes again after oxyhydrogen flame high temperature hydrolytic condensation
It is modified scion grafting and obtains；
Except aldehyde auxiliary agent is by solid acid gel entrapment and to seal a kind of solia particle formed in chitosan microencapsulation up for safekeeping,
Solid acid colloids include SiO2-Al2O3 colloid or B2O3-Al2O3 colloid is one such or two kinds of mixture.
When chitosan is introduced into solid acid colloids matrix, there is no chemical changes, and pass through chemical treating process
Chitosan molecule is redistributed and has been assembled in solid acid gel networks, and reticular structure more closely is formed, and is generated
More abundant gap structure, the surface area of microcapsules and mesopore volume are all very big after processing, easily absorption gaseous formaldehyde.It removes
Aldehyde auxiliary agent has uniform microspheroidal form.Gaseous formaldehyde absorption test experiments show that microcapsules adsorbance that treated is very
Height is far longer than the formaldehyde absorbing amount of the cocoanut active charcoal of same amount.First under the catalysis of solid acid colloids, in microcapsules
Azomethine and schiff bases are formd between primary amine in aldehyde molecule and chitosan, and by formaldehyde under the action of aerial oxygen
Resolve into water and carbon dioxide.
In the process for preparation coating material solidified except aldehyde UV, due to the requirement of product various luster degree, it usually needs in coating
The dumb light powders such as middle addition white carbon black.At that time in the actual use process, the additive amount of the dumb light powders such as common white carbon black is found
It acts on clearly except aldehyde promoter effect.Except aldehyde auxiliary agent except aldehyde shows in the less bloom timber floor of dumb light powder adding proportion
Normally, more obvious except aldehyde performance declines except aldehyde auxiliary agent in the more dumb light timber floor of dumb light powder adding proportion.Its reason can
It can be that dumb light powder destroys solid acid colloids and microcapsule shell, cause to decline except aldehyde builder activity.
Modified gas phase SiO obtained from silane or silicone-modified scion grafting2Physics and chemical property etc. are highly stable, will not
Solid acid colloids and microcapsule shell are destroyed, additive amount is unobvious to the influence showed except aldehyde auxiliary agent except aldehyde.It is possible thereby to make
The effect for all having very excellent removing formaldehyde of the timber floor of various luster degree.
It is 3-8g/ ㎡ except the coating weight of the coating material solidified coating twice of aldehyde UV is identical.
In some embodiments, when first time coating is coating material solidified except aldehyde UV, ultraviolet energy is 80~100mj, is shone
Penetrating the time is 1~2 second；
When second of coating is coating material solidified except aldehyde UV, ultraviolet energy is 300~400mj, and irradiation time is 3~4 seconds.
Coating twice can form equitant two UV solidification coatings, and ultraviolet energy is relatively when first time coating
Low, polymeric nucleus is few when solidification, and polymeric chain is longer, convenient for forming fine and close solidify coating；And second of coating constantly ultraviolet light
Energy is relatively high, and polymeric nucleus is more when solidification, and polymeric chain is relatively disconnected, convenient for forming porous solidify coating.
Fine and close coating can play the role of closed, barrier and remove the micro formaldehyde that timber floor itself volatilizes.
And porous coating can then greatly improve the absorption efficiency to the formaldehyde in indoor environment, to improve formaldehyde
Elimination effect.
