Description
Technical field
The present invention relates to a kind of interior wall coating, and in particular to a kind of physical absorption and chemical catalysis combine and remove the anti-of formaldehyde
Bacterium coating and preparation method thereof.
Background technology
Formaldehyde is a kind of colourless, there is the gas of intense stimulus type smell.Soluble in water, alcohol and ether.The World Health Organization exists
No. 153 publication identification of issue in 2004：Formaldehyde is carcinogenic and cause deformed material.Formaldehyde is generally acknowledged allergen,
One of it is one of potential strong mutagen, and cause the hazards of child's leukaemia.According to the country medical journal and
Pertinent literature reports that harm of the indoor formaldehyde to health can be summarized as stimulation, toxic action and carcinogenesis.
Due to growth in the living standard, increasing people likes being fitted up in its house, but enters luggage in house
When repairing, come from the artificial boards such as the glued board used during interior decoration, core-board, medium density fibre board (MDF) and particieboard, family
Tool, fabrics furniture, kitchen furniture can all produce the health that formaldehyde endangers people, while it is harmful also to produce benzene, heavy metal, VOC etc.
Material.
Therefore, there has been proposed various methods, such as the sprinkling of plant absorption method, cleanser, charcoal absorption etc..
But although the above method can clear up formaldehyde, many deficiencies are still suffered from, for example, plant absorption method purification efficiency is low, effect
Unobvious；Cleanser spray effect is not lasting, and some cleansers simply cover smell, can not eliminate formaldehyde.Activated carbon
The suction-operated of PARA FORMALDEHYDE PRILLS(91,95) is obvious, but needs often to change, it is impossible to the formaldehyde in fully erased air.
Although being developed the latex paint formulation of various anti-formaldehyde at present, it is bad to still suffer from discomposing effect,
The technical problems such as decomposition efficiency is low, anti-microbial property is poor.
The content of the invention
The present invention is bad for existing anti-methanal paint discomposing effect, and the technologies such as decomposition efficiency is low, anti-microbial property is poor are asked
Topic, there is provided a kind of physical absorption and chemical catalysis combine antibiotic paint for removing formaldehyde and preparation method thereof.
The technical scheme that the present invention takes is as follows：
One aspect of the present invention provides a kind of physical absorption and chemical catalysis combines the antibiotic paint for removing formaldehyde, including such as
The raw material of lower parts by weight：Anti- Formaldehyde as Additives 5-10 parts, nano-silver colloid 1-5 parts, polyurethane modified acrylic resin 20-25 parts,
Thickener 0.2-0.5 parts, defoamer 0.2-0.5 parts, titanium dioxide slurry 6-9 parts, wetting agent 0.8-1.4 parts, water 10-20 parts, its moderate resistance
Contain graphene, nano titanium oxide and diatomite in Formaldehyde as Additives.
Further, graphene, nano titanium oxide and diatomaceous weight ratio are in the anti-Formaldehyde as Additives:1-4：4-
2：4-2.
Further, the thickener is that association type alkali soluble rises thickener and polyurethane thickener.
Further, the wetting agent in glycerine, propane diols, sorbester p17, sorbester p18, Tween 80, tween 90 one
Kind is a variety of.
Further, the defoamer is that mineral hydrocarbon defoamer and/or nonionic alkyl copolymer disappear
Infusion.
Another aspect of the present invention provides a kind of preparation method of the antibiotic paint as described above for removing formaldehyde, including：
Polyurethane modified acrylic resin is added in dispersion cylinder to be disperseed, and is then mixed into water, anti-Formaldehyde as Additives, Nano Silver by proportioning
Glue, thickener, defoamer, titanium dioxide slurry, wetting agent, after disperseing 40min, sampling detection finished product reaches predetermined fineness and predetermined viscosity
Afterwards, filtering.
Further, rate of dispersion 700r/min.
Further, the predetermined fineness is 35-50 μm.
Further, the predetermined viscosity is 30-50mm2/s。
The method that the present invention is combined using physical absorption and chemical catalysis removes formaldehyde, considerably increases point of PARA FORMALDEHYDE PRILLS(91,95)
Solve efficiency.Diatomite is a kind of pure natural environment protection raw material, and the molecular sieve structure of diatomite protrusion has extremely strong physical adsorbability
Energy and ion-exchange performance, the harmful substances such as the formaldehyde to dissociate in air, benzene are effectively eliminated, releasing negative oxygen ion, purify air.
Simultaneously using the light transmittance of graphene, make it as photocatalysis carrier, greatly improve the efficiency of light-catalyzed reaction.Meanwhile it will receive
Meter level titanium dioxide is added in graphene, adds visible-light absorptivity, and improve electronics conduction efficiency.Furthermore by graphite
Alkene is effectively compound with nano titanium oxide, not only improves dispersiveness of the nano titanium oxide in graphenic surface, and pass through
The compound of photo-generate electron-hole is reduced, improves the photocatalytic activity of nano titanium oxide.At the same time, due to band structure
Adjustment, graphene will also play sensitising agent effect, the absorption region of nano titanium oxide is extended to visible region, have
Effect improves utilization rate of the photocatalyst to sunshine.And due to the addition of graphene, add the anti-wear performance of aqueous latex paint.
Nano-silver colloid is also added in the coating of the present invention as antimicrobial component, improves the antibiotic property of coating of the present invention
Energy.
