The reflective heat-insulating coating comprises the following components in parts by weight: 5-10 parts of reflective heat-insulating emulsion, 35-45 parts of light reflective heat-insulating colored sand, 1-3 parts of a coalescing agent and 15-25 parts The reflective heat-insulation stone-like finish paint adopts light reflective heat-insulation color sand, has a good reflective heat-insulation effect, and also has a lower heat conductivity coefficient, so that the heat-insulation and energy-saving effects of the reflective heat-insulation stone-like finish paint applied to a reflective heat-insulation building coating system are further improved, and building energy conservation is more effectively realized.

Description

technical field [0001] The invention belongs to the field of architectural coatings, in particular to a reflective heat-insulating architectural coating system. Background technique [0002] Reflective heat insulation coating is a surface coating material with high solar reflectance, near-infrared reflectance and hemispherical emissivity, which can reflect part of the sunlight or heat reaching the building surface, thereby reducing the heat absorbed by the building and achieving The heat insulation effect is mainly suitable for areas with warm winter and hot summer; while the thermal insulation material is a substance with low thermal conductivity, which can block and reduce the heat conduction speed to achieve the heat preservation effect. This is the essential difference between reflective heat insulation coatings and thermal insulation materials. Through the working mechanism and performance of these two materials, it can be seen that the reflective thermal insulation co...

AI Technical Summary

Problems solved by technology

[0005] 1) The basic raw material is natural white sand, which has poor batch stability and large differences in color and main component composition between batches;

[0006] 2) The particle size distribution of white sand is wide, and the surface is rough. It is difficult to obtain a uniform and smooth dyeing surface during dyeing, resulting in low reflectivity of the finished product, which affects the reflection and heat insulation effect;

[0007] 3) Concrete mechanical stirring devices and drying drums are used for dyeing. During the dyeing process, the sand particles are rubbed and collided to produce more fine powder, and the coating on the surface of the dyed sand is seriously damaged, which affects the reflection and heat insulation effect of the finished coating;

[0008] 4) It is necessary to add about 5% hollow glass microspheres or hollow ceramic microspheres to meet the technical requirements, and the hollow glass microspheres or hollow ceramic microspheres are easily damaged during the production and mixing process of the finished paint due to their own strength problems, thus lose its efficacy
