Organic-inorganic composite waterborne aluminum powder paint and preparation method thereof

The invention provides an organic-inorganic composite waterborne aluminum powder paint and a preparation method thereof. The waterborne aluminum powder paint comprises the raw materials: 30-45 parts of styrene-acrylic emulsion or pure acrylic emulsion, 0.3-0.8 part of an antifoaming agent, 0.5-2.0 parts of a film forming aid,15-20 parts of water, 5-15 parts of filler, 5-8 parts of waterborne aluminum powder, 0.3-1 part of a thickener, and 15-25 parts of inorganic silicate; the preparation method comprises the following steps: adding the antifoaming agent and the film forming aid into the emulsion, and performing uniform dispersing; adding the filler and the aluminum powder into the water to be wetted into a slurry, adding the wetted slurry into the emulsion to which the aid is added, performing uniform dispersing, adding the thickener, detecting the viscosity to reach the specified value, adding the silicate under stirring, performing uniform dispersing, and measuring and packaging theproduct after the produc
