Abstract

The invention provides a waterborne polyurethane weather-proof elastic waterproof paint. The paint comprises an emulsion, a filler, a pigment, an accessory ingredient and water, wherein the emulsion comprises an elastic waterproof emulsion and waterborne polyurethane prepolymer; the filler comprises talcum powder, ceramic powder and light calcium carbonate; the pigment is of mica powder; and the accessory ingredient comprises the following components: propylene glycol or ethylene glycol, film-forming accessory ingredient, a sterilizing agent, a flatting agent, a dispersing agent, a thickening agent, an antifoaming agent, an ultraviolet light absorber and a pH regulating agent. The problems of complicated using process of the paint, low elasticity, poor crack resistance and poor ultraviolet radiation in the prior art are solved. The invention also provides a production method of the paint, and is used for solving the production problem of the waterborne polyurethane weather-proof elastic waterproof paint.

Description

technical field [0001] The invention relates to the technical field of paint production, in particular to a water-based polyurethane weather-resistant elastic waterproof paint. Background technique [0002] The common problem of the existing polyurethane waterproof coatings is that the coatings contain coal tar and toluene solvent which are harmful to the human body, and most of them are packaged in two components, which are very inconvenient when they are remixed during use. With the increasing awareness of environmental protection, the requirements for architectural coatings are getting higher and higher. It is required that architectural coatings be harmless, and the use process is simplified. At the same time, they have high elasticity and good crack resistance, which can effectively resist wall microcracks and cracks. It protects the wall from wind and rain, is suitable for areas with strong ultraviolet radiation, and also has excellent durability and weather resistance...
