[0002] In the production process of polyurea waterproof coatings, a mixing step is required. Polyurea waterproof coatings generally include component A and component B, with component A accounting for more than 80% and mainly including polyether and polyester. Component B mainly includes bactericides, defoamers, fillers, plasticizers, curing agents, etc. During the production process, components A and B need to be mixed. Since the content of component B is in a small amount, its input amount needs to be controlled during the mixing process. Existing mixing equipment directly adds components, and the ratio cannot be precisely controlled. Moreover, due to the direct stirring and mixing method, the mixing effect is not particularly good.
