AI Technical Summary

Technical Problem

Existing antiquities tiles have poor aging resistance and limited adhesion, and cannot achieve long-lasting hydrophobic self-cleaning properties while maintaining a matte texture and a waxy, silky feel.

Method used

The preparation method combines waxy anti-fouling matte glaze and etching hydrophobic liquid. The etching hydrophobic liquid forms stable silicon-fluorine bonds on the surface of matte antique bricks, which, combined with nano-scale calcium feldspar microcrystals and micron-scale barium feldspar crystals, construct a dense microstructure and enhance hydrophobic self-cleaning properties.

Benefits of technology

It achieves excellent and long-lasting hydrophobic self-cleaning properties, high anti-fouling performance, hardness and wear resistance on the basis of matte texture and waxy silky feel, overcoming the problems of insufficient aging resistance and limited adhesion of existing hydrophobic self-cleaning coatings.

Abstract

The application relates to the field of building ceramics, in particular to a hydrophobic matte antique brick and a preparation method thereof, which comprises the following steps: A, preparing a ceramic base material, pressing the ceramic base material, and obtaining a body layer after drying; B, applying a wax anti-fouling matte glaze material on the surface of the body layer to obtain a wax anti-fouling matte glaze layer; C, drying and then putting into a kiln for calcination to obtain a matte antique brick semi-finished product; and D, soaking the matte antique brick semi-finished product in etching hydrophobic liquid, taking out and drying to obtain a hydrophobic matte antique brick. The hydrophobic matte antique brick and the preparation method thereof have the advantages that the obtained hydrophobic matte antique brick not only has excellent and long-lasting hydrophobic self-cleaning property, but also has high anti-fouling property, hardness and wear resistance on the premise of having a matte texture and a wax-like smooth hand feeling.
