AI Technical Summary
Existing dry-grained rock slabs have shortcomings in terms of antibacterial properties and acid and alkali resistance, especially in surface structures with obvious undulations and abundant micropores, making it difficult to simultaneously achieve antibacterial durability, acid and alkali resistance stability, and improved surface granular texture.
After ball milling core-shell structured antibacterial composite powder with dry ceramic particles, titanium zirconium silica sol is sprayed on and sintered. Subsequently, flexible polishing and silicon-modified boron-containing polyester coating are applied to form a dense inorganic oxide barrier and an organic-inorganic hybrid composite protective layer.
It effectively seals micropores, blocks acid and alkali penetration, enhances Mohs hardness and antibacterial durability, and ensures chemical stability and mechanical resistance in extreme environments.
