[0051] In a second aspect, an embodiment of the present invention provides a method for preparing a dust-proof coating, the preparation method comprising the following steps:
[0052] Add water, emulsifier, polytetrafluoroethylene microspheres with an average particle size of 2 μm or less, fluorine-containing (meth)acrylate monomer and fluorine-free (meth)acrylate monomer into the reactor, mix uniformly and Heating up to a preset temperature, and then adding an initiator to the reactor within the first preset time, when the initiator is added, continue to react at the preset temperature for a second preset time to obtain the dust-proof coating;
[0053] The amount of water added is 400-850 parts by weight, the total amount of fluorine-containing (meth)acrylate monomers and non-fluorine-containing (meth)acrylate monomers is 90-110 parts by weight, and the polytetrafluoroethylene microspheres The addition amount of is 0.5~2 parts by weight.

Embodiment 1
[0072] This embodiment provides a kind of dustproof coating, and this dustproof coating is prepared by the following method:
[0073] In the reactor, add 800g distilled water, 2g sodium dodecyl sulfate (SDS), 4g average particle diameter and be the water dispersion liquid of the polytetrafluoroethylene microsphere of 0.12 μ m (the quality of polytetrafluoroethylene microsphere in the aqueous dispersion liquid) Fraction is 50%), 15g methyl methacrylate, 60g butyl acrylate and 25g dodecafluoroheptyl methacrylate, after stirring evenly, be warmed up to 90 ℃, in 2 hours, drop by 1g ammonium persulfate in the reactor Initiator solution prepared with 20g of distilled water. After the initiator solution was added dropwise, the reaction was continued at 90° C. for 1 hour, and then the reaction system was cooled to normal temperature to obtain a dust-proof coating.
