Description

technical field [0001] The invention relates to a paint, in particular to a heat-insulating stone-like paint for exterior walls and a preparation method thereof. Background technique [0002] Heat-insulating imitation stone paint (also known as heat-insulating real stone paint) is a new type of high-grade energy-saving material that has become popular in recent years. It is suitable for unused base surfaces and shapes, and has a wide range of uses. It not only meets the requirements of national energy-saving standards, but also meets the requirements of environmental protection and safety. It has strong decorative effects and high cost performance. It shows a rapid upward trend in exterior wall decoration. The traditional heat-insulating real stone paint generally uses light-weight materials with low thermal conductivity such as ceramic hollow microspheres added to ordinary real stone paint as heat-insulating fillers. The finished real stone paint surface is constructed wit...

Problems solved by technology

In traditional products, the thermal conductivity is reduced by adding ceramic hollow microspheres. If the amount is large, the heat insulation effect will be obvious, but it will affect the color development. Only white or light colors are suitable.

The natural colored sand or artificial dyed sand or sintered colored sand used in general colored sand does not have the function of infrared reflection, and will absorb most of the infrared rays, which will affect the heat insulation effect instead.

In order to achieve the effect of heat insulation, many colors cannot be selected. The surface of real stone paint itself is rough and easily polluted by the outside world, which affects the life of heat insulation.
