[0028] Example 1
[0029] The invention provides a preparation method of water-based high-adhesion and water-resistant paint, comprising the following steps:
[0030] (1) The halide salt, copper ion salt and sulfite salt are mixed and reacted according to the molar ratio of 2.8:1.5:1 for 1 h, and then barium halide is added to the mixed solution to react and filter to remove the precipitate to obtain the cuprous halide complex ion [CuX 2 ] - solution, to [CuX 2 ] - Add stabilizer to the solution for use;
[0031] (2) The mass components are 20 parts of polyurethane resin, 30 parts of water-based acrylic resin, 15 parts of epoxy resin, 0.8 parts of hydroxymethyl cellulose, 25 parts of monovalent alginate, 22 parts of water and stabilized [CuX 2 ] - The solutions are mixed and stirred uniformly to obtain the water-based high-adhesion and water-resistant paint.
[0032] wherein the halide salt, barium halide, cuprous halide complex ion [CuX 2 ] - The halogen element X is...
