摘要 |
<p>Method for preparing a ceramic shaped article (A) having a photocatalytically active coating (B). Method for preparing a ceramic shaped article (A) having a photocatalytically active coating (B) comprises: (1) preparation of a liquid phase (X) containing at least one of silica sol and polyacrylic acid (PAA) and/or its ammonium, alkali or alkaline earth salts; (2) adding photocatalytically active particles to (X); (3) applying the resulting dispersion, as a coating, to a shaped ceramic article; and (4) drying and/or hardening the treated article. Alternatively, the coating is prepared by adding (C) to the liquid phase first, then adding silica sol and/or PAA (or its salts). INDFEPENDENT CLAIMS are also included for the following: (1) (A) in which the coating (B) has high adhesion strength; and (2) use of zinc oxide, silicate or titanate and/or titanium dioxide as biostatic agent on ceramic articles, especially roofing tiles.</p> |
