step S100, uniformly mixing a first resin, a first dispersing agent and a thixotropic agent according to a preset mass part to prepare a base material, and uniformly mixing a pearlescent pigment, a second resin and a second dispersing agent to prepare color paste;

and S200, uniformly mixing the base material, the color paste, the film forming auxiliary agent, the coupling agent and the flatting agent to prepare the waterproof paint finish.

In the embodiment of the invention, the first resin, the first dispersing agent and the thixotropic agent are mixed uniformly to prepare the base material, the pearlescent pigment, the second resin and the second dispersing agent are mixed uniformly to prepare the color paste, and then the base material, the color paste, the film-forming assistant, the coupling agent, the flatting agent and other assistants are mixed uniformly to obtain the waterproof paint finish paint. The base material and the color paste are prepared respectively and then mixed to form the waterproof paint finish, so that the full mixing of all the components can be ensured, the pearlescent pigment is uniformly dispersed in the resin base material, and the color uniformity of the finish is improved.

In the embodiment of the invention, in the process of preparing the waterproof paint finish, the resin comprises a first resin and a second resin, the dispersing agent comprises a first dispersing agent and a second dispersing agent, and the mass ratio of the pearlescent pigment, the resin, the film forming additive, the defoaming agent, the thixotropic agent, the coupling agent, the dispersing agent and the leveling agent is 5-30: 70-200: 1-3: 0.3-1: 1-3: 1-2: 3-6: 1-3, and sequentially adding the first resin, the first dispersant, the thixotropic agent, the pearlescent pigment, the second resin, the second dispersant, the film-forming assistant, the coupling agent and the leveling agent, so that the finally prepared finish paint comprises, by mass, 5-30 parts of the pearlescent pigment, 70-200 parts of the resin, 1-3 parts of the film-forming assistant, 0.3-1 part of an antifoaming agent, 1-3 parts of the thixotropic agent, 1-2 parts of the coupling agent, 3-6 parts of the dispersant and 1-3 parts of the leveling agent.
