Abstract
The present invention relates to nano composite latex paint which is prepared from 0.3 to 1 wt% of moistening dispersant, 2 to 70 wt% of nano pulp, 1 to 4 wt% of film-forming adjuvant, 0.5 to 2 wt% of anti-sedimentation agent, 0.8 to 15 wt% of antifreeze agent, 0.5 to 3 wt% of defoaming agent, 5 to 30 wt% of pigment, 0 to 30 wt% of filler, 10 to 45 wt% of emulsion, 0.2 to 2 wt% of thickening agent, 0.2 to 2% of leveling agent, 0 to 2 wt% of pH regulating agent, 0 to 2 wt% of microbiocide and 2 to 35 wt% of water. A preparation method for the nano composite latex paint comprises the following two steps: firstly, preparing nano material slurry with stable dispersion; secondly, adding the nano material slurry in components of latex paint according to a certain technique, and preparing the high performance nano composite latex paint. The latex paint containing nano slurry of the present invention improves the water resistance, the alkali resistance, the scrubbing resistance, the dust adhesion resistance and the weatherability of a coating layer, effectively avoids the carbonization of concrete and protects building walls when the ornamentation is enhanced.
Description
Technical field
The present invention relates to coating technology, be specially a kind of nano composite latex paint and preparation method thereof.
Background technology
Emulsion paint is a kind of water-borne coatings, and contained organic volatile is very low, meets environmental protection requirement, belongs to " green coating ".Obtained very great development after emulsion paint produces, people constantly improve every performance of emulsion paint by every means from different aspects.The raising that appears as the emulsion paint performance of nano material has brought opportunity.A kind of building coating of the 0.5-1.5% of containing silicon-base oxide is disclosed as Chinese invention patent CN1277234A.Suspension, cohesive strength, ageing resistance and the stain resistance of coating have been improved.Chinese invention patent CN1287145A has reported a kind of nanometer paint for external wall with preparations such as nano silicon-based oxide, nano-titanium oxide, titanium dioxide, filler and emulsions, has good resistance to soiling, mildew-resistant, anti-algae and long acting antibiotic effect.But the abrasion resistance of these two kinds of coating, package stability are not very good.
Summary of the invention
The purpose of this invention is to provide a kind of nano composite latex paint and preparation method thereof, it has performances such as good storage stability, resistance to deterioration, abrasion resistance.
Technical scheme of the present invention is:
A kind of nano composite latex paint, by weight percentage, be made of following component: 0.3～1% wetting dispersing agent, 2～70% nanometers slurry, 1～4% film coalescence aid, 0.5～2% anti-settling agent, 0.8～15% frostproofer, 0.5～3% defoamer, 5～30% pigment, 0～30% filler, 10～45% emulsions, 0.2～2% thickening material, 0.2～2% flow agent, 0～2%pH adjust agent, 0～2% microbicide, 2～35% water.
Described nanometer slurry is made up of 0.2～80% nano silicon-based oxide, 0.2～80% nano-titanium oxide, 0.2～80% nano zircite, 15～90% water, 0.5～10% wetting dispersing agent; Nanometer slurry content is 5～60% preferably.
Described wetting dispersing agent is that one or more of natural polymer subclass, synthetic macromolecule class, polyvalent carboxylic acid's class is mixed.
Described wetting dispersing agent can be mixed for one or more of block macromolecular copolymer analog, special polyvinyls.

The preparation method of nano composite latex paint of the present invention is by its weight percent with described component, the preparation of employing two-step approach, it is the nano material slurry that the first step prepares stably dispersing, second step joined the nano material slurry in the component of emulsion paint by certain processing method, and the concrete steps in second step are as follows:
1) water is put into the container of homogenizer earlier, (add microbicide, film coalescence aid, wetting dispersing agent, defoamer, anti-settling agent, frostproofer under 100～400rpm) successively at low speed, the nanometer slurry after mixing, slowly adds pigment and filler in the vortex of high speed dispersor; After adding material, improve wheel speed, make its rotating speed 1200～1800rpm, after fineness qualified (20～60 μ m), promptly disperse to finish;
2) after dispersion finishes, adjust the rotating speed of high speed dispersor, make that it adds emulsion gradually at 100～400rpm, pH adjusts agent, adjustment emulsion paint pH value is in 8～9 scopes, stormer viscosity to 70～120KU with thickening material and flow agent adjustment emulsion paint makes nano composite latex paint after sieving.
Advantage of the present invention is as follows:
(1) nano material used in the present invention slurry mainly is made up of the nano powder that the particle diameter of stable dispersion is generally less than 100nm, this method makes nano material easier dispersion in coating, solved the compatibility issue of nano material and emulsion, color stuffing, auxiliary agent well, it is more stable that nano composite latex paint is stored.
(2) the homodisperse nanoparticle of the present invention easily is filled in the hole or the pore of coating; improve the permeability resistance of coating, and improved water tolerance, alkali resistance, the polluting proofing property of coating, prevented carbonization of concrete effectively; improving the ornamental while, also protected building masonry wall.
(3) the present invention is because the specific surface area of nanoparticle is big, and surfactivity is big, be very easy to coating in other component produce chemical bonding, make that sticking power is greatly improved, scrub performance significantly improves.
(4) the present invention utilizes nanoparticle to ultraviolet scattering of light and sorption, has improved the guarantor's look and the gloss retention of emulsion paint, has strengthened the ageing resistance of filming.
