AI Technical Summary

Technical Problem

Existing ceramic rock slabs have deficiencies in terms of anti-fouling and wear resistance, especially the surface is easily contaminated and difficult to clean, and the production process is complex and time-consuming and energy-consuming.

Method used

A three-layer ceramic rock plate design is adopted, including a body layer, a base glaze layer, a surface glaze layer and an inkjet pattern layer. Through an oxygen-nitrogen plasma activation post-treatment process, combined with the hydrothermal reaction of aluminum sulfate 18hydrate and an ammonia source compound, a micro-nano structure is formed, and then a low surface energy coating is formed with silane derivatives and a curing agent to construct a synergistic protective layer.

Benefits of technology

It significantly enhances the anti-fouling and wear-resistant properties of ceramic rock slabs, forms a stable hydrophobic state, improves the surface's anti-fouling ability and durability, and simplifies the production process.

Abstract

The invention discloses a ceramic rock plate with a decorative effect and a production process thereof, and belongs to the technical field of ceramics. The rock plate is composed of a green body layer, a ground glaze layer, a cover glaze layer and an ink jet pattern layer, and after firing, a micro-nano rough and low-surface-energy synergistic protection layer is formed through oxygen-nitrogen plasma activation, a hydrothermal reaction of aluminum salt and an ammonia source compound, high-temperature calcination and silane derivative dipping and curing. The green body takes wollastonite, quartz sand and the like as raw materials, and the ground glaze and the cover glaze adopt a feldspar-quartz-nepheline system; after firing, performing plasma treatment and hydrothermal treatment to generate needle-shaped aluminum oxide, and introducing a silane derivative to realize double functions of super-hydrophobicity and wear resistance. Compared with the prior art, the anti-fouling and wear-resistant coating reaches the national standard 5 level, the process is simple, and the coating can be directly connected to an existing production line and is suitable for high-end wall floor decoration.
