High-strength waterproof coating and preparation method thereof

The invention discloses high-strength waterproof coating and a preparation method thereof. The high-strength waterproof coating is made mainly from epoxy resin, methacrylic acid, acetoacetoxy ethyl methacrylate and chitosan by resin pre-emulsifying, self-crosslinking and mixing with an aid. The high-strength waterproof coating is simple to prepare, the materials are easy to obtain, the high-strength waterproof coating is easy for construction, has a large angle of contact with water and good waterproof effect, allows droplets to easily flow down the surface, has long hydrophobic life and high strength, and is suitable for the surface treatment field for common metals (aluminum, copper, steel and the like), building materials, glass and the like, and other fields; the high-strength waterproof coating is universal in the field of common industrial and domestic materials.
