Description
Technical field
The present invention designs a kind of coating and preparation method thereof, particularly a kind of low VOC antibacterial environment protection type family expenses emulsion paint.
Background technology
The friendly type coating of development environment is the hot issue of present coating industry, and in the coating between the control of VOC content and the film performance how balance also be present puzzlement people in the friendly type coating of development environment
Problem.In fact, VOC is from the angle of macroscopic view, affect atmospheric environment, damage the ozone layer, environment for whole human survival works the mischief, and from the aspect of microcosmic, it also directly threatens the every aspect of our life, even can cause to our health great injury, should not say so at present more to be subject to the coating products of society and consumers in general's concern than emulsion paint especially interiro wall latex paint on whole Coating Market, big and small coating material production producer all makes a fuss at the topic of VOC content.
Low VOC emulsion paint refers to that content of volatile organic compound in the emulsion paint is lower than the Limited Doses of GB 18582-2008 standard codes (≤120g/L) kind.Low VOC is the important symbol of environmental protection coating material, in latex paint formulation design, select low VOC content and low film formation temperature synthetic resin emulsion, abandon film coalescence aid and glycols frostproofer, be the main method that reduces VOC.
Nano material because of it has that particle diameter is little, specific surface area is large, the particle micropore mainly with and the characteristic such as high adsorption capacity, the suspension stability of raising coating and the aspects such as bonding force between coating and the base material there are obvious effect, can significantly improve compactness, surface finish and the abrasion resistance of filming; Utilize the photocatalysis characteristic of nano material, can catalyzed degradation some harmful organic compound, suppress the breeding growth of various mushrooms, play antibiotic and effect sterilization.
Summary of the invention
One of purpose of the present invention is the defective for above prior art, a kind of interiro wall latex paint of environment-friendly type is proposed, it is toxicological harmless in the use of producing, construct not only, coating strength is good simultaneously, VOC content is low, the anticorrosive mildewproof good anti-bacterial effect, and can decompose the interiro wall latex paint that is harmful to organic compound in the surrounding environment.
Two of purpose of the present invention provides the preparation method of above-mentioned emulsion paint.
In order to realize above goal of the invention, the present invention by the following technical solutions: a kind of low VOC antibacterial environment protection type emulsion paint comprises following component: deionized water 30% ~ 33% by weight percentage; Walocel MT 20.000PV 0.1% ~ 0.2%; Dispersion agent 0.6% ~ 0.9%; Defoamer 0.2% ~ 0.3%; Composite nano materials 18% ~ 25%; Negative ion antibiotic additive 0.8% ~ 1.0%; Talcum powder 5% ~ 6%; Dicalcium powder 4% ~ 5%; Fine particle calcium carbonate 5% ~ 6%; Kaolin 5% ~ 8%; Cyhalothrin 0.3% ~ 0.5%; Pure-acrylic emulsion 18% ~ 22%; Thickening material 0.2% ~ 0.5%; Flow agent 0.4% ~ 0.5%.
Described composite nano materials is nano-TiO
2, two or three in nano-ZnO, nanometer Ag O or the nano-MgO mixture.
Described dispersion agent is polycarboxylate sodium's dispersion agent.
Prepare the method that the present invention hangs down VOC antibacterial environment protection type emulsion paint according to above proportioning, may further comprise the steps:
(1) deionized water, dispersion agent, composite nano materials, negative ion antibiotic additive, defoamer are stirred after, be ground to fineness less than 50 μ m through sand milling;
(2) stir lower adding Walocel MT 20.000PV, until fully dissolving; Add talcum powder, dicalcium powder, fine particle calcium carbonate, kaolin, cyhalothrin, high speed dispersion 40 ~ 50 min, check slurry fineness reaches below the 20 μ m; Stirring at low speed in the change adds pure acrylic latex, mix 30 min after, add thickening material, flow agent, adjust pH and approximate 8 and get final product.
Nano material because of it has that particle diameter is little, specific surface area is large, the particle micropore mainly with and the characteristic such as high adsorption capacity, the suspension stability of raising coating and the aspects such as bonding force between coating and the base material there are obvious effect, can significantly improve compactness, surface finish and the abrasion resistance of filming; Utilize the photocatalysis characteristic of nano material, can catalyzed degradation some harmful organic compound, suppress the breeding growth of various mushrooms, play antibiotic and effect sterilization.Nano-TiO
2, nano-ZnO, nanometer Ag O and nano-MgO the experiment proved that the effect that all has stronger antibiotic and sterilization.
Negative ion-antimicrobial additive, this is the functional materials that a kind of anion-generating material combines with inorganic antibacterial material.Anion-generating material can form permanent electric microfield, by electrode pair air and moisture faint electrolytic action occuring produces hydroxyl ion, hydroxyl ion is by effects such as neutralization, chemical reaction and physical adsorptions, decompose the obnoxious flavoures such as the formaldehyde dispel in the room air, ammonia, benzene, have the function of dispelling abnormal flavor, fresh air; Inorganic antibacterial material can constantly be separated out to film coated surface, reacts with bacterium attached thereto, the zymoprotein of mould, causes zymoprotein sink-float or loses activity, the survival of anti-bacteria and growing.
Beneficial effect of the present invention is: coating strength is good, and VOC content is low, the anticorrosive mildewproof good anti-bacterial effect, and can decompose harmful organic compound in the surrounding environment, have the obvious feature of environmental protection.
