Abstract

A method for forming an antifouling coating disposed on the surface to be treated of a substrate having a surface comprising a plastic or a rubber, which contains a photocatalyst and an amorphous titanium peroxide having substantially no photocatalytic activity, characterized in that it comprises a step of subjecting the surface to be treated of the substrate to a dry treatment for introducing a hydrophilic group onto the surface, and a step of applying an aqueous coating material containing a photocatalyst and an amorphous titanium peroxide having substantially no photocatalytic activity on the resultant surface after the treatment; and an antifouling material having an antifouling coating formed by the method. The dry treatment is preferably a plasma discharge treatment, a corona discharge treatment or an ultraviolet irradiation treatment.

Description

Technical field

[0001] The present invention relates to a method for forming an antifouling coating film that is arranged on a substrate having a surface composed of plastic or rubber and contains a photocatalyst and amorphous titanium peroxide that has substantially no photocatalytic ability, and has the use of The antifouling material of the antifouling coating formed by this method. Background technique

[0002] When a photocatalyst such as titanium oxide is irradiated with ultraviolet or visible light, active oxygen will be generated on the surface of the photocatalyst. Therefore, the active oxygen can decompose organic matter such as bacteria, oil, or inorganic gas such as nitrogen oxide; On the surface of the photocatalyst, the hydrophilic groups that are more easily compatible with water will also increase, so the water will spread on the photocatalyst, and pollutants, etc., can float. Therefore, research on the use of photocatalysts for air purification, deodorization, wa...
