Description
Technical field
The invention belongs to paint field, and in particular to a kind of interior wall removes formaldehyde-latex paint and preparation method thereof.
Background technology
Emulsion paint has the advantages that easy for construction, dried coating film is quick, good permeability compared with other coating, emulsion paint quilt
It is widely applied in interior wall and exterior wall, because exterior wall is vulnerable to the influence of weather, it is necessary to have fabulous anti-for the invasion and attack of rainwater
It is water-based.At present, in order to reach preferable filming performance, coalescents and antifreezing agent are all contained in common commercially available emulsion paint.
Contain substantial amounts of organic volatile in emulsion paint（VOC）, the main component in organic volatile is formaldehyde, and formaldehyde is tight
Heavily contaminated environment, is harmful to human body, or even can cause the symptom such as headache, Nausea and vomiting, weak, and serious also resulting in is taken out
Jerk, go into a coma, injury human liver, kidney, brain and nervous system, cause the serious consequences such as failure of memory, be chronically at height
The environment for spending formaldehyde can also be carcinogenic.
At present except the physical method of formaldehyde includes ventilation method and active carbon adsorption, the method for ventilation removes formaldehyde
Time it is longer and efficiency is low, formaldehyde is still present in air, does not remove formaldehyde fundamentally；Added in emulsion paint
Activated carbon is the formaldehyde adsorption by activated carbon, but formaldehyde is still stored in activated carbon, potential safety hazard be present.
Nano TiO 2 powder and rare earth material are added except the chemical method of formaldehyde is included in emulsion paint, but in breast
In shellac varnish add nano TiO 2 powder method can with catalytic degradation formaldehyde, but Titanium Dioxide oxidation efficiency compared with
It is low；The method that rare earth filler is added in emulsion paint can be with catalytic degradation formaldehyde, but adds a small amount of rare earth filler catalysis effect
Rate is low, and the efficiency of catalytic degradation formaldehyde can be improved by adding more rare earth filler, but also human body can be caused to radiate simultaneously
Injury.
The content of the invention
It is an object of the invention to provide a kind of interior wall except formaldehyde-latex paint and preparation method thereof, the emulsion paint is main
Including VAE emulsions, except the compositions such as Formaldehyde as Additives, superfine alumina silicate, the preparation method of the emulsion paint it is simple to operation.The present invention
Using VAE emulsions, coalescents and antifreezing agent are not added, effectively reduce the content of formaldehyde in emulsion paint.
Main following technical scheme of the invention is realized：A kind of interior wall removes formaldehyde-latex paint, is calculated according to mass parts main
Including following component：VAE emulsions：30-40 parts；Except Formaldehyde as Additives：0.5-5 parts；Superfine alumina silicate：1-3 parts；Filler：20-40
Part；Nano-meter SiO_22：5-10 parts；Thickener：2-5 parts；Dispersant：0.5-2 parts；Defoamer：1-3 parts；Water：15-30 parts.
The VAE emulsions are the abbreviations of vinyl acetate-ethylene copolymerization emulsions, and it using vinyl acetate and vinyl monomer is basic to be
Raw material, add the macromolecule emulsion that emulsifying agent and initiator are formed by the copolymerization of high pressure emulsion polymerization.VAE emulsions are by acetic acid
Ethene（Content is between 70%-95%）It is made with vinyl monomer through being copolymerized, there is preferable pliability, resistance to acids and bases, weather resisteant,
And there is good compatibility and film forming characteristics, it is widely used in coating for internal and external wall.Because VAE has preferable film forming
Characteristic, therefore addition can not even add coalescents less.
It is described except Formaldehyde as Additives is titanium dioxide-graphene composite material, be by titanium dichloride load on graphene.Stone
Black alkene is one kind with SP2The hexangle type two-dimension plane structure of hybridized orbit composition, therefore there is larger specific surface area, high electricity
Sub- transporting, good electrical and thermal conductivity.When graphene and TiO2Compound tense, the unique electron transport property of graphene can make
The recombination rate for obtaining photo-generated carrier substantially reduces, so as to greatly strengthen TiO2Photocatalysis effect；It can strengthen again simultaneously
The absorption of PARA FORMALDEHYDE PRILLS(91,95), expand photoresponse scope, improve photo-catalysis capability.It is described except Formaldehyde as Additives is titanium dioxide-graphene
Composite, graphene is reduced by graphene oxide and obtained, the graphene oxide in the titanium dioxide-graphene complex
Weight ratio with titanium dioxide is 0.1-0.5.
When light is irradiated to nano-TiO2On particulate, light induced electron-hole pair is formed, light induced electron and photohole can
Reacted with direct and cell membrane, cell membrane or cell constituent, cause cell function unit to inactivate and reach the effect of sterilization
Fruit；On the other hand, photohole obtains electronic capability with very strong, can also make the oxygen activation in air, produces active oxygen and oneself
By base, reactive oxygen species and free radicals have very high reactivity, when pollutant is adsorbed in its surface, will with free electron or
Hole combines, and redox reaction occurs, so as to reach the purpose for eliminating pollution.
The superfine alumina silicate has the characteristics of intensity is high, oil absorption is low, easily scattered, and has cellular ultramicropore knot
Structure, it is porous material, can effectively adsorbs the formaldehyde in air.Then in titanium dioxide-graphene composite material
TiO2The formaldehyde of superfine alumina silicate absorption is subjected to catalytic degradation.
The Nano-meter SiO_22Powder can increase that frictional behaviour of emulsion paint, increase the compactness of emulsion paint film, so as to
Increase the water resistance of emulsion paint film.
The filler is the one or more in kaolin, powdered whiting, diatomite, talcum powder, wollastonite, described to fill out
The particle diameter of material is 800-1200 mesh.The particle diameter of filler directly affects the consistency of emulsion paint film, the thinner emulsion paint of particle diameter of filler
Film it is finer and close, water resistance is better.
In order to preferably realize the present invention, further, the thickener be hydroxymethyl cellulose, hydroxyethyl cellulose,
Any one in methylcellulose, hydroxypropyl methyl cellulose.
A kind of interior wall except the preparation method of formaldehyde-latex paint, mainly include the following steps that：
Step A, by superfine alumina silicate, filler, Nano-meter SiO_22It is placed in grinder after powder, dispersant, water are well mixed
Row grinding, the average grain diameter of grinding are more than 400 mesh；
Step B, by the solution ground in step A, defoamer, hydroxyethyl cellulose, except Formaldehyde as Additives, thickener, defoamer,
VAE emulsions mix, and first stir 30min in 400-600r/min rotating speeds, are then stirred under 1200-1500r/min rotating speeds.
In order to preferably realize the present invention, further, milling time is 20-35min in the step A.Milling time
It is not easy long, is on the one hand waste of resource, is on the other hand the activity loss that heating causes dispersant when preventing grinding.
Beneficial effects of the present invention：
（1）Using VAE emulsions, coalescents are not added, effectively reduce the content of formaldehyde；
（2）Using titanium dioxide-graphene composite material as formaldehyde formulations are removed, by TiO2It is loaded on graphene, enhances
TiO2Photocatalysis efficiency；
（3）Using superfine alumina silicate formaldehyde adsorption, the then TiO in titanium dioxide-graphene composite material2Further photocatalysis
Degradation of formaldehyde；
（4）Using first by superfine alumina silicate, filler, Nano-meter SiO_22It is well mixed that powder, dispersant, water are ground into slurry；Then mix
Other compositions are closed, rotating speed is incrementally increased and prepares emulsion paint, the emulsion paint performance of preparation is homogeneous, stably.
