Abstract
The invention relates to nano-paint and a preparing method thereof, and belongs to the technical field of paint. Nano-titanium dioxide and other nano-particles are added, the particle size is about one tenth that of common titanium dioxide and is far smaller than wavelength of visible light, and the nano-particles have transparency. Ultraviolet light in sunlight can be effectively shielded, and the ageing-resistant performance of a paint film is substantially improved. As the added inorganic nano-particles are excellent in performance and have a good synergistic effect with other components, the nano-particles in the paint are high in stability, and the nano-paint can stands for one month or more without layering. The nano-paint is good in low-temperature film-forming property and can be constructed under any weather condition.
Description
Technical field
The present invention relates to a kind of coating, relate to a kind of nano paint and preparation method thereof particularly, belong to technical field of coatings.
Background technology
Nano paint is generally composited by nano material and organic coating, more strictly says to be called and receives composite coating.Nano composite dope must meet two conditions: one is have a kind of yardstick of material at least between 1-100nm, and two is that nanometer mutual-assistance coating property is significantly improved or adds New function, and Neither of the two can be dispensed.In a broad sense, nano paint material comprises two kinds: metal nano coating and inorganic nano paint.Metal nano coating mainly refers to containing nanometer crystalline phase in material, inorganic nano paint be then by nanoparticle between melting, sintered combined and obtain.Usually said nano paint is organic nano composite coating.
The preparation method of nano paint can be divided into four kinds: (1) sol-gel method, by the in-situ preparation of nanoparticle in monomer or resin solution.(2) situ aggregation method, refers to that nanoparticle is directly dispersed in monomer, generates nano paint after polymerization.(3) blending method, refers to the composite of nanoparticle and resin solution or emulsion.(4) graft process, enters inorganic nano interlayer by monomer or polymers soln, obtained nano paint, but this method is only suitable for the layered inorganic material of polynite one class.
But also have a lot of problem anxious to be resolved at present in the development research of nano composite dope, wherein the problem of most critical is the dispersion how ensureing that nanoparticle is effectively stable in coating.If the nanoparticle in nano paint disperses bad, not only do not reach expection object, also likely destroy the stability of coating.
Summary of the invention
The present invention, for solving the problem, the invention provides nano paint, excellent performance, and good stability.Be made up of the component of following number, described number is weight part:
Wherein, described base-material is made up of the component of following number, and described number is weight part:
Hydroxylated cellulose 12-18 part;
Fluorine carbon emulsion 18-22 part.
Wherein, described nano inoganic particle is made up of the component of following number, and described number is weight part:
Nano titanium oxide 5-11 part;
Nano-sized iron oxide 2-4 part;
Nano zine oxide 3-5 part.
Wherein, described dispersion agent is made up of the component of following number, and described number is weight part:
Polyvinylpyrrolidone 3-7 part;
Paraffin 1-3 part.
Wherein, described frostproofer is made up of the component of following number, and described number is weight part:
Ethylene glycol 8-9 part;
Propylene glycol 4-7 part.
The preparation technology of nano paint of the present invention is as follows:
(1) above-mentioned each component is added mixing tank, after being uniformly mixed 1-3h with the shearing rate of 2000-3000r/min under room temperature, then ultrasonic disperse 2-4h.
(2) said components is ground, namely filter mechanical impurity obtains nano paint of the present invention excessively.
Beneficial effect
1, the particle diameter of nano titanium oxide is approximately 1/10th of ordinary titanium powder, and well below the wavelength of visible ray, itself has the transparency, is a kind of stable, nontoxic UV light absorber.Effectively can shield the ultraviolet in sunlight, significantly improve the ageing-resistant performance of paint film.
2, nano-sized iron oxide is nonpoisonous and tasteless as pigment, has the premium properties of good heatproof, weather-proof, acidproof, alkaline-resisting and high adhesive force, high-clarity and strong absorption UV-light.
3, nano zine oxide has the advantages such as quality is light, thickness is thin, of light color, wave-sucking performance is strong, nano zine oxide has extremely strong chemically reactive in water and air under irradiation by sunlight, can with gas chromatography generation oxidizing reaction (comprising the organism in bacterium), thus most of bacterium and virus eliminate.
4, nano inoganic particle process itself has excellent performance, and has good synergy with other components, makes nanoparticle good stability of the present invention, and standing more than one month not stratified.
5, film formation at low temp of the present invention is good, all can construct throughout the year under any weather condition.
