Description
Technical field
The present invention relates to building material field, particularly a kind of have a photochromic aqueous inner wall paint of reversibility.
Background technology
Reversibility photochromic material is a kind ofly can rise or decline and repeatedly change the material of color with temperature, it is generally prepared by electron transfer type organic compound, under the rayed of particular range of wavelengths, can cause this organism generation transfer transport, thereby this organic molecular structure is changed, thereby realize the transformation of color.The reversible temperature-sensing discoloring material of micro encapsulation is that mean diameter is the spherical particle of 2 ~ 7 microns; its inside is electrochromic substance; outside is that approximately 0.2 ~ 0.5 micron of thick layer neither can dissolve the transparent outer cover that also can not melt, and it can protect electrochromic substance to avoid the erosion of other chemical substances.
Being of wide application of reversibility photochromic material, as plastic cement, ink, coating etc.Take that to be applied in coating be example, most of reversibility photochromic material is applied in oil paint, and the scope of brushing is generally plastic cement, metal etc.In the prior art, be applied in photochromic coating on wall seldom, and be mainly used in exterior coating, be applied at present in interior wall coating rarely found.
In modern decorative material for internal wall, people can not meet the only decoration functions of interior wall coating, and functional diversities and personalization are development trends.Reversibility photochromic material is introduced to interior wall coating, it can reach a lot of purposes, such as: people can make according to solar radiation the variation of wall color generation roughly judge outdoor uitraviolet intensity, by the variation of indoor wall color, be alleviated eye strain, passed through the variation increase interest of indoor wall color etc. on indoor wall.
It is 200710149321.8 that State Intellectual Property Office discloses an application number, patent name is the another kind of photochromic coating > of < < >, this invention is to mix and be added in coating system with mineral dye with pigment dyestuff, realizes the change of color by the variable color of organic color.But there is certain shortcomings and deficiencies part in this invention; as sensitization discoloration material easily produces light fatigue; be generally because excessively tan by the sun, the factor impact such as acid, free radical and humidity; therefore; in order to alleviate light fatigue; generally sensitization discoloration material protection need to be got up, as by sensitization discoloration material micro encapsulation etc.And in this invention, only have to describe and add stablizer, having no the description of the concrete material of stablizer, this still may cause product prolongation in time, and variable color is more and more not obvious.In addition, organic photo coating is generally used for oil paint, produces and use all not environmental protection.
For above situation, study a kind ofly by reversible sensitization discoloration material micro encapsulation, there is the photochromic aqueous inner wall paint of reversibility just significant.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of by reversible sensitization discoloration material micro encapsulation, has the photochromic aqueous inner wall paint of reversibility.
The technical scheme that the present invention solves the problems of the technologies described above is: of the present invention a kind of to have the photochromic aqueous inner wall paint of reversibility be to adopt following weight percent formula.
Reversibility photoreception microcapsule aqueous liquid dispersion 10 ~ 30%, 5040 dispersion agents 0.5 ~ 2%, 2, 2, 4-trimethylammonium 1, 3-pentanediol mono isobutyrate 0.5 ~ 2%, Polyacrylate thickeners 0.2 ~ 0.5%, 2-amino-2-methyl-1-propanol 0.1 ~ 0.5%, calcium carbonate 15 ~ 30%, kaolin 5 ~ 10%, mica powder 5 ~ 10%, polyoxyethylene octylphenol ether 1 ~ 3%, titanium dioxide 2 ~ 8%, 705 type EVA emulsions 10 ~ 20%, AGITAN-208 type defoamer 0.1 ~ 0.3%, Kathon CG 0.1 ~ 0.3%, Octabenzone 0.1 ~ 0.3%, UV-1130 type uv-absorbing agent 0.2 ~ 0.5%, water surplus.
The microcapsule median size of single order reversibility photoreception microcapsule aqueous liquid dispersion of the present invention is 3 ~ 10 μ m, the solid content of dispersion liquid is 40 ~ 50%, when having light source to irradiate, color is not colourless, Show Color when having light source to irradiate, displayable color is a kind of in purple, orange, green, yellow, grey.
Preparation method of the present invention comprises the steps.
Take in proportion 705 type EVA emulsions, add Octabenzone and UV-1130 type uv-absorbing agent, dispersed with stirring becomes uniform emulsion, obtains latex A.
In stirring tank, add in proportion water, then add 5040 dispersion agents, 2,2,4-trimethylammonium 1,3-pentanediol mono isobutyrate, polyoxyethylene octylphenol ether, 2-amino-2-methyl-1-propanol, AGITAN-208 type defoamer and Kathon CG, and stir.
Take in proportion calcium carbonate, kaolin, mica powder and titanium dioxide, and be added in the dispersion liquid of previous step and continue to disperse.
Latex A is continued in dispersion liquid disperse, finally add Polyacrylate thickeners to regulate denseness, after stirring, add temperature-sensitive microcapsule aqueous liquid dispersion, finally filling, packing.
Sensitive materials of the present invention absorbs the energy of sunlight, and the change that has produced molecular structure, causes the change of absorbing wavelength, thereby color is changed, and after losing sunlight, replys original molecular structure, is reduced into original color.The present invention is by adopting microcapsulary, by having during pigment that reversibility light becomes incapsulates, can completely cut off and extraneous contacting, thereby it has stable performance, the advantage such as is difficult for being disturbed.Simultaneously, photoreception microcapsule is prepared into dispersion liquid, can allow photoreception microcapsule disperse equably in water-borne coatings, and form the coating system of stable in properties, thereby solve the problem of disperseing inhomogeneous, unstable and easy layering when photoreception microcapsule is directly added in coating.Single order reversibility photochromic coating brushing prepared by the present invention, on wall, can realize wall color for white and coloured change.
