Abstract

The invention provides a nanocrystalline plate, which comprises a foam nanocrystalline glass layer, a colored nanocrystalline glass layer and a TiO2-SiO2 antibacterial coating from bottom to top, wherein the colored nanocrystalline glass layer is formed by melting upper-layer colored nanocrystalline blocks and lower-layer colored nanocrystalline powder and has texture within the layer. A preparation method for the nanocrystalline plate comprises the following steps: a. grinding broken nanocrystalline plates into powder; b. mixing nanocrystalline glass powder, a foaming agent and a foam stabilizer to prepare a foam glass ceramic mixture; c. successively putting the foam glass ceramic mixture, the colored nanocrystalline powder and the colored nanocrystalline blocks into a refractory mold; d, carrying out firing, melting and foaming; and e, successively carrying out coating with TiO2-SiO2 gel and calcining. The nanocrystalline plate of the invention has good heat-insulating property, small specific gravity, high mechanical strength, beautiful appearance and good anti-bacterial effect; the water resistance of the nanocrystalline plate is improved by 50 to 60% compared with ordinary microcrystalline plates; and the nanocrystalline plate can be widely applied to interior decoration.

Description

technical field

[0001] The invention belongs to the field of building materials, in particular to a nano-microcrystalline plate. Background technique

[0002] Nano-microcrystalline plate is a composite material composed of crystals and solid solutions with excellent physical and chemical properties, which is formed by controlling the nano-microcrystallization process of the crystal nucleus inside the material through a specific composition formula. It has high mechanical strength, hardness and tensile strength. High strength, high gloss, expansion coefficient (1~80) × 10 -7 / °C, water absorption < 0.05%, good acid and alkali resistance and excellent thermal shock resistance, at 500 °C, it will not burst when placed directly in water or air, and the whole is intact. It can be widely used as furnace panels, building decoration materials, countertops, wear-resistant acid and alkali resistant castings, seals, etc. The surface of the polished nano-microcrystalline plate has ...
