Examples 1 to 3 provide a photochromic real stone paint for building exterior walls, wherein the components and contents of the photochromic building paint are shown in table 1:
TABLE 1 EXAMPLES 1-3 Components and amounts of color-changing architectural coatings
The preparation method of the photochromic real stone paint coating specifically comprises the following steps:
s1, preparing a small molecule compound with a photochromic functional group: 1-allyl-2, 3, 3-trimethylindoline and 5-chlorosalicylaldehyde are mixed and reacted in an ethanol solution at the reaction temperature of 60 ℃ and are refluxed for 6 hours to finally generate the 1-allyl-6-chloro spiro [ 2H-1-benzopyran-2, 2' -indoline ].
S2, preparing photochromic acrylic emulsion by emulsion polymerization: methyl methacrylate, acrylic acid, an initiator (benzoyl peroxide) and N, N-dimethylformamide, 1-allyl-6-chloro spiro [ 2H-1-benzopyran-2, 2' -indoline ] are contained in a solution, mixed and heated to 78-82 ℃ and reacted for 4 hours.
S3, preparation of pre-emulsion: mixing an emulsifier (a mixed solution of OP-10 and sodium dodecyl benzene sulfonate with the mass ratio of 2: 1), methyl methacrylate, acrylic acid and an initiator (benzoyl peroxide), heating to 78-82 ℃, reacting for 4 hours, and simultaneously dropwise adding the modified pure acrylic emulsion within 4 hours. And mixing and reacting for 2 hours to obtain the pre-emulsion.
S4, adding the pre-emulsion into a leveling agent (polyether silicone oil), a defoaming agent, an electronic conductive agent, an amine compound, natural quartz sand and magnesium aluminum silicate, and uniformly stirring to obtain the photochromic real stone paint.
Wherein the defoamer of example 1 is a polyether; the electronic conductive agent is polyphenylacetylene; the amine compound is ammonium chloride.
The antifoaming agent of example 2 is a fatty-based antifoaming agent; the electronic conductive agent is polypyrrole; the amine compound is ammonia water.
The defoamer of example 3 was dimethicone; the electronic conductive agent is polypyrrole; the amine compound is a mixture of ammonium bicarbonate and ammonium chloride.
To further illustrate the beneficial effects of the present invention, the photochromic stone-like paint prepared in example 1 of the present invention was selected according to JB/T9327-1999 Meter Standard. The prepared photochromic real stone paint coating is coated on a polytetrafluoroethylene plate, air-dried to form a film with the thickness of 1mm, the film is irradiated by ultraviolet light with the wavelength of 280-350 nm for 5 minutes, the whiteness is immediately tested by a whiteness meter (WSB-2), the ultraviolet light irradiation is removed for 5 minutes, and then the whiteness value is tested, wherein the table 2 shows the change condition of the whiteness.
TABLE 2 change of whiteness under different illumination conditions
| When it is illuminatedWorkshop | 0 minute | 5 minutes | 5 minutes after removal of the light |
| Example 1 | 30 | 17 | 31 |
The whiteness test shows that the prepared photochromic real stone paint is darker and light yellow before illumination, the whiteness is reduced and light white after illumination, and the original color can be recovered after illumination is removed.
