Description
Technical field:
The invention belongs to the technical field of coating, particularly relate to interiro wall latex paint, specifically one has nano-TiO
2light-catalyzed zero-VOC interior wall latex coatings and preparation method thereof.
Background technology:
Most people has the time over half to spend in indoor in all one's life.And room air pollution degree is about higher than outdoor 2-5 times.Improve IAQ (indoor air quality) just very important to raising health of people level.
Our said Environmentally friendly coatings at present, generally refers to the coating substantially not affecting or do not affect environment.But this not enough, people also can air purifying coating in effort exploitation.
General light catalyzed coating is all ultraviolet catalytic coating, and general light catalyzed coating is all the coating containing VOC (volatile organic matter).Indoor almost do not have UV-light, only have visible ray, and general light catalyzed coating does not have katalysis.
Summary of the invention:
The object of the present invention is to provide a kind of TiO
2interiro wall latex paint and preparation method thereof, this coating is Diamond Search, under visible ray effect, just can eliminate hazardous and noxious substances.
For achieving the above object, technical scheme of the present invention is as follows: a kind of TiO
2interiro wall latex paint, it is characterized in that: described emulsion paint is by carbon-doped nano titanium deoxid, emulsion, dispersion agent, defoamer, thickening material, sanitas, titanium dioxide, calcium carbonate, talcum powder, kaolin and water composition, their weight percentages of components is, carbon-doped nano titanium deoxid 3-8%, emulsion 20-35%, dispersion agent 0.3-0.7%, defoamer 0.2-0.4%, thickening material 0.4-0.8%, sanitas 0.1-0.3%, titanium dioxide 10-25%, calcium carbonate 10-25%, talcum powder 5-10%, kaolin 3-7%, surplus is water, their weight percent sum is 100%.
A kind of TiO
2the preparation method of light-catalyzed zero-VOC interior wall latex coatings, described TiO
2the preparation method of light-catalyzed zero-VOC interior wall latex coatings comprises following steps:
A. slurrying, be the water of 18-47%, the dispersion agent of 0.3-0.7%, the sanitas of 0.1-0.3%, the defoamer of half and 10-25% titanium dioxide by weight percent, 10-25% calcium carbonate, 5-10% talcum powder, 3-7% kaolin, add successively, the high shear being about 20-25m/s in dispersion impeller perimeter line speed makes slurry;
B. paint, under the condition of stirring at low speed, add the thickening material of 20-35% emulsion, second half defoamer and 0.4-0.8%, carry out paint, concrete paint technique is prior art.
The present invention is owing to employing the coating be made into as photocatalyst containing nano titanium oxide, its photocatalytic mechanism is, be made into coating by nano titanium dioxide photocatalyst, when by radiation of visible light, the photocatalyst of this semi-conductor is stimulated generation electron-hole pair.Electronics and hole make the oxygen of surrounding and water molecules become living radical, and living radical can by organic or inorganic pollutent in air, as oxynitrides (NOx), formaldehyde, benzene, sulfurous gas etc., Direct Resolution becomes harmless material, thus reach decontamination, the object purified air.
Visible light catalytic Diamond Search emulsion paint performance
This light-catalyzed zero-VOC interior wall latex coatings, press GB/T18801-2002 " air purifier " through Chinese Center for Disease Control environment and health related products safety institute to test, Degradation Formaldehyde speed per hour more than 30%, NO2 degradation speed per hour more than 30%, ammonia degradation speed per hour more than 30%.Press GB/T21866-2008 " antibiotic paint (film) germ resistance assay method and antibacterial effect " test through Shanghai City Industry Wei Biological Research Institute inspection center, all 99.9% was greater than to the antibiotic rate of intestinal bacteria and streptococcus aureus in 24 hours.
This light-catalyzed zero-VOC interior wall latex coatings, through Shanghai coating and the test of pigment quality inspection station, result is as table 1.It is not only Diamond Search product, and performance is far away higher than the requirement of premium grads in GB/T9756-2001 " resin latex dope ".
