Water-based acrylic ester insulating paint and preparation method thereof

The invention provides water-based acrylic ester insulating paint and a preparation method thereof. The water-based acrylic ester insulating paint comprises the following raw materials in parts by weight: 25-38 parts of a soft monomer, 62-78 parts of a hard monomer, 1-10 parts of an adhesive force monomer, 1-8 parts of a phosphate monomer containing double bonds, 2-6 parts of a crosslinking monomer, 2-6 parts of an emulsifier, 0.2-0.4 part of an initiator and 150-170 parts of water. According to the insulating paint, a phosphate monomer containing double bonds is introduced, so that a phosphate group is combined with cations on the surface of a metal base material to form a compact phosphate salt, and the concentration of free metal ions on the surface of the base material is reduced, so that metal is passivated, the metal is prevented from being in contact with water or other media, and an excellent anti-corrosion effect is achieved. According to the preparation method of the insulating paint, insulating pai
