Granite-imitated water permeable plate and preparation method thereof

The invention relates to a granite-imitated water permeable plate and a preparation method thereof, and belongs to the technical field of water permeable plates. The granite-imitated water permeable plate is formed by firing a bottom material and a surface material; the base material comprises an auxiliary agent and aggregate with grain composition; and the surface material comprises an auxiliary agent and colored stone particles with grain composition, and the colored stone particles are one, two or more than three of colored stone particles, potassium feldspar, albite or mica sheets. The colored stone particles adopted in the fabric are beneficial to presenting the characteristics that granite natural particles are different in size and shape and rich and colorful in color, the granite texture of the granite-imitated water permeable plate presents rich layering sense by adopting a specific particle grading mode, and the texture looks more natural. And the potassium-sodium feldspar particles have a semi-tran
