Title:
POROUS ARTICLE TREATED PRODUCT AND ITS MANUFACTURE
Document Type and Number:
Japanese Patent JPH11188703
Kind Code:
A
Abstract:

To possess antibiotic physical properties, non-environmental pollution properties, etc., which are effective for a long period of time by improving photocatalyst activity of a semiconductor particulate and its dispersibility by a method wherein a treating agent containing the semiconductor particulate having photocatalyst action which is fluorinated is applied to a porous article and/or the article is impregnated therewith.

As a semiconductor particulate used for a fluorinated semiconductor particulate-containing treating agent wherein it is applied to a porous article and/or the article is impregnated therewith, titanium oxide is preferable. As a pretreatment, a coincidence treatment, or an after-treatment of a porous article treatment with a treating agent containing the fluorinated semiconductor particulate, the treatment with a treating agent containing a phenolic compound and/or a metallic compound can be executed. Thereby, the fluorinated semiconductor particulate is more firmly bonded to the porous article, a sticking tendency of the fluorinated semiconductor particulate can be raised, and antibiotic physical properties to be added to the porous article can be adjusted. Then, the antibiotic physical properties of the semiconductor particulate come to be enabled to be used.
