Description
Technical field
The invention belongs to adhesive technical fields, and in particular to a kind of wallpaper adhesive reducing Form aldehyde release.
Background technology
Wallpaper, also referred to as wallpaper are a kind of quite extensive house decorative materials of application.Because wallpaper has color more
A variety of other house decorative materials such as sample, pattern be abundant, luxurious style, safety and environmental protection, easy for construction, affordable can not compare
Quasi- feature, it has also become a kind of home decoration products of prevalence are increasingly liked by people.
But a large amount of formaldehyde can be discharged after existing adhesive use, it is detrimental to health, how to reduce in adhesive
Current technical problem to be solved when burst size of methanal.
Invention content
The purpose of the present invention is for existing problem, provide a kind of wallpaper adhesive reducing Form aldehyde release.
The present invention is achieved by the following technical solutions：
A kind of wallpaper adhesive reducing Form aldehyde release contains the modified porous of its quality 7.5-9.5% in the adhesive
Coconut shell flour.
Further, the modified porous coconut husk powder, preparation method thereof is：
(1) coconut husk is dried to moisture content to 10%, then crushes the coconut husk after drying, crossed 250 mesh sieve, obtain coconut shell flour；
(2) coconut shell flour obtained above is pressed into 50g:It is molten that the ratio of 300mL is added to the 3- pyridones that mass fraction is 0.35%
In liquid, 73 DEG C are heated to, 40min is stirred with 1000r/min rotating speeds, obtains mixed serum, mixed serum pH to 5.2 is adjusted, obtains
To acidic mixed slurries；
（3）The cellulase of its quality 0.12% is added into acidic mixed slurries obtained above, constant temperature is handled at 41.5 DEG C
4.5 hours, obtain enzymolysis liquid；
(3) enzymolysis liquid obtained above is adjusted into pH to 10.2, keeps the temperature 1 hour at 55 DEG C, then, is centrifuged, then
It is cleaned to neutrality by deionized water, drying to constant weight, crushes, and crosses 300 mesh sieve to get modified porous coconut shell flour.
Further, the adjusting mixed serum pH to 5.2 is that mass fraction is used to be adjusted for 10% acetum
Section.
Further, it is described by enzymolysis liquid obtained above adjusting pH to 10.2 be use mass fraction for 10% hydrogen-oxygen
Change potassium solution to be adjusted.
Further, the adhesive further includes following parts by weight of component：Lauxite 92-95, nano diatomite ethyl alcohol
Dispersion liquid 2.5-2.8, curing agent 1.1-1.3.
Further, the nano diatomite alcohol dispersion liquid preparation method is：
Nano diatomite after coupling agent treatment is pressed into 50g：It is 15% that the ratio uniform of 180mL, which is distributed to mass fraction,
In ethanol solution, the saturation ammonium hydroxide of ethanol solution quality 0.5% is then instilled again, with 3000r/min rotating speeds stirring 2 hours, i.e.,
?.
Further, the nano diatomite after coupling agent treatment is that the nano diatomite for being 90nm by granularity is adopted
The organo silane coupling agent solution for being 10.2% with 10 times of mass fraction of its quality is at 82 DEG C, and 40min is impregnated in stirring, then
Filtering, drying to constant weight, you can.
Further, the curing agent is ammonium chloride.
The present invention has the following advantages compared with prior art：Prepared by the present invention has the wallpaper for reducing Form aldehyde release performance
There is good cementing strength with adhesive, wallpaper usage time can be greatly improved；The present invention is more by preparing modification
Modified porous coconut shell flour is added in adhesive by hole coconut shell flour, and modified porous coconut shell flour dispersibility in adhesive is very good,
It is prevented from caking, it can uniformly be mixed with adhesive, will not precipitate and bottom or float on glue surface layer, stability is high, effectively
Uniformity of size application is improved, meanwhile, adhesive burst size of methanal prepared by the present invention is significantly reduced, so as to have
Effect so as to have ensured that health safety, the modified porous coconut shell flour added in adhesive of the present invention are disperseed in adhesive
It is even, burst size of methanal in adhesive can be effectively reduced, is replaced using starch or peanut shell powder modified porous in the present invention
Coconut shell flour, although having certain reduction Form aldehyde release effect, its reducing effect obviously and not as good as using the present invention changes
The porous coconut shell flour of property, meanwhile, Form aldehyde release can further be improved using nano diatomite alcohol dispersion liquid to a certain extent
Reducing effect.
