Problems solved by technology

[0004] At present, the production of reflective heat insulation coatings usually uses titanium dioxide, PU hollow microspheres, hollow microspheres, ceramic microspheres, expanded perlite and a small amount of nano-reflective heat insulation functional materials to achieve the reflective heat insulation function, but its existence The shortcomings of rough coating film and poor decoration also reduce the stain resistance of the coating film; at the same time, due to the limitation of the natural environment and construction conditions, the thermal insulation material coating of the exterior wall of the building often results in the deterioration of the thermal insulation material after coating. The expected effect cannot be achieved during use, which puts forward higher technical requirements for the operation process of the building exterior wall in the construction process of coating thermal insulation materials

Description

technical field [0001] The invention relates to the technical field of exterior wall coatings, in particular to a reflective and heat-insulating exterior wall coating and a preparation method thereof. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. The authoritative book "Painting Technology" in the Chinese coatings industry defines: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a solid adhesion, a certain strength, and a continuous state. Thin film. The film formed in this way is commonly called coating film, also known as paint film or coating.” In the early days, most of the paints used vegeta...
