Technical Field

[0001] The invention belongs to the technical field of imitation stone paint, and particularly relates to a lotus leaf effect 6D imitation stone paint and a preparation method thereof. Background Art

[0002] High-end exterior walls are mostly constructed using natural dry-hang stone, which is expensive and has a high specific gravity. The marble's texture easily harbors dirt, breeding mold and moss, which can penetrate and be difficult to clean, severely impacting the exterior's decorative effect. Current exterior wall paint, however, is subject to high levels of dust and buildup, making it difficult to clean. Summary of the Invention

[0003] In order to solve the drawbacks of natural granite such as high cost, high specific gravity, and difficulty in cleaning stains, the present invention provides a lotus leaf effect 6D imitation stone paint and a preparation method. The lotus leaf effect 6D imitation stone paint prepared by the method has low cost, light weight, energy saving and environmental protection, and a realistic effect of imitating natural granite. It can be constructed without a topcoat, saving construction costs. The coating of the paint film has a simulated lotus leaf effect and has super strong stain resistance and self-cleaning ability. Raindrops can carry dust and stains and roll down, and the frequency and difficulty of cleaning the exterior walls can be reduced. The surface of the 6D imitation stone paint is like a lotus leaf effect and does not breed mold. It can keep the walls of the house as long as new and has a service life of up to 30 years.
