Reflection and heat-insulation finish paint for external wall and preparation method thereof

Abstract

The invention relates to the field of coating and in particular relates to reflection and heat-insulation finish paint for an external wall and a preparation method thereof. The reflection and heat-insulation finish paint is prepared from the following raw materials: 80 to 120 parts of a pure acrylic emulsion, 20 to 40 parts of heat reflection powder, 40 to 60 parts of titanium dioxide, 20 to 25 parts of mica powder, 3 to 8 parts of barium sulfate, 1 to 5 parts of silicon dioxide, 4 to 8 parts of propylene glycol, 4 to 8 parts of a film-forming auxiliary agent, 0.3 to 0.5 part of a defoaming agent, 2 to 4 parts of a thickening agent, 2 to 3 parts of a dispersant and 0.4 to 0.6 part of a wetting agent. According to the reflection and heat-insulation finish paint for the external wall, the added titanium dioxide, mica powder and silicon dioxide have excellent ultraviolet ray shielding performance, infrared ray shielding performance and the like; the auxiliary heat reflection powder is added so that the coating has very high reflectivity; the coating can reflect solar radiation very well, and also has heat-insulation and cooling effects; the coating provided by the invention also hasgood performance including weather resistance, attachment force, freezing resistance and the like.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a reflective thermal insulation finish paint for exterior walls and a preparation method thereof. Background technique [0002] Driven by real estate, automobiles and ships, my country's coatings industry is growing day by day. As one of the important categories, architectural coatings have also achieved rapid development. Architectural coatings have decorative functions, protection functions and habitability improvement functions. Compared with decoration materials such as stone and ceramic tiles, they have obvious advantages in energy consumption and cost. Therefore, in the field of interior and exterior wall decoration of buildings, the popularity of architectural coatings is gradually increasing. improve. The past 10 years have been called the "Golden 10 Years" of the real estate industry, and the coatings industry has also taken the opportunity to achieve rapid development. At pres...

[0003] Building energy conservation occupies a major position in the national energy conservation. At present, materials such as polystyrene and extruded plastics are used to insulate buildings through construction techniques such as mounting and wrapping. Although these materials can also play a role in heat insulation, However, these materials have the disadvantages of being easy to burn, polluting the environment, complex construction technology, and short service life.
