Example Embodiment
[0031] Example 1:
[0032] A wall paint containing nanometer titanium dioxide, the components and the mass percentages of each component are as follows:
[0033] Nano titanium dioxide 0.1%;
[0034] Emulsion 20%;
[0035] Titanium dioxide 25%;
[0036] Filling 40%;
[0037] Film forming agent 2%;
[0038] Additive 0.5%;
[0039] Distilled water 17.4%;
[0040] The nano titanium dioxide is an anatase nano titanium dioxide smaller than 10 nanometers; the emulsion is a pure acrylic emulsion. The filler is selected from one or a mixture of calcium carbonate, diatomaceous earth, kaolin or talc. The film forming agent is selected from pentanediol monoisocyanate. The auxiliary agent is a bactericide, an antifungal agent, and a wetting agent. The fungicide is selected from methyl isoxazolinone; the antifungal agent is selected from carbendazim. The wetting agent is selected from nonionic surfactant siloxane copolymers.
