た。2. Description of the Related Art Recently, there have been attempts to use photocatalysts to decompose, purify, or sterilize harmful substances, odorous components, oils, and the like that occur in daily living environments. ing. In order to utilize such a photocatalytic function, the photocatalyst is usually used in a form coated on a surface of a substrate such as glass. However, most photocatalyst coating liquids require heating as film forming conditions, and the thickness of the photocatalyst coating is usually about 0.1 to 2.0 μm, which is the case for a normally used transparent photocatalyst coating. However, it is difficult to confirm the film formation and photocatalytic ability required for the enforcement management, so it is necessary to use a coating solution for photocatalyst-related coatings that has been used in existing buildings and construction sites. It has been considered difficult to commercialize the formed film.

かつ基材の色や質感を変えないという特徴を有する。As TiOCOAT-H, a transparent solution of an inorganic water repellent containing a methyl silicate compound as a main component can be specifically mentioned. This TiOCOAT-H exhibits alkalinity (pH 12.0), is colorless and transparent, and has a strong resistance to ultraviolet rays, temperature changes, and harmful substances because it is made of a mixture of only inorganic substances. It can be stored and can be applied even if the base material is not completely dry.In addition, it can penetrate deeply into the base material such as concrete to create a water-repellent layer and maintain air permeability. It has the effect of preventing water absorption, producing hydrophobic crystals, densifying the surface, and improving the surface tensile strength of embrittled concrete by 20 to 50%.

造膜施工工法を選択する必要がある。The method for forming a film according to the present invention, when forming a film using a coating agent for a photocatalyst-related coating film stored in a container, is performed by a film forming method selected based on a specific method selection standard. The film is formed on the surface of the base material. Construction method selection criteria are (A) construction place; outdoor / indoor, (B) base material surface material; organic / inorganic material, (C) required function; photocatalyst / photocatalyst plus surface protection or water absorption prevention , (D) the amount of ultraviolet rays; The method of forming a film depends on the type of coating agent for photocatalyst-related coatings that can be used and how to use it, depending on the construction site and site, the material of the base material, etc.For example, when the base material is an organic substance, the base material has a photocatalytic action It is necessary to provide a blocking layer in order to protect it from light, and there is a difference in the intensity of ultraviolet light received depending on the construction place and site. In general, except for places exposed to direct sunlight, 1/100 to 1/500 times outdoors. Indoors, which have only a small amount of ultraviolet light, do not have sufficient antifouling functions, especially for surfaces that require more ultraviolet light than gas decomposition in the atmosphere. It is necessary to select a membrane construction method.

光触媒機能の必要性についての分類表を表１に示す。In selecting a film forming method, it is particularly important to classify whether the base material belongs to an organic base material or an inorganic base material. Even if the base material itself is an inorganic material, Some finishes are classified as organic substrates. For example, aluminum itself is an inorganic material, but most of aluminum panel products and the like have a clear coating applied to the surface, and the surface finishing paint is an organic substance and is classified as an organic base material. In addition, among the base materials made of inorganic base materials, the base materials such as concrete and mortar where the construction place and site are outdoors are deteriorated because the surface deteriorates and the base material itself deteriorates due to the penetration of rainwater. In materials, surface protection,
It is necessary to have a photocatalytic function for preventing water absorption. Next, Table 1 shows a classification table for general organic materials and inorganic substrates, which are general building materials, and for the necessity of surface protection and water absorption prevention photocatalytic function.

At this time, it is preferable that coating is performed in several steps, taking care not to allow the coating liquid to drip. In the case of a coloring method using an organic dye, it is preferable that the coating be performed so that the color after coating is uniform, and in the case of coating a plurality of times, the next coating is performed after the previous coating is completely dried.

For this purpose, dirt that may interfere with film formation is removed from the surface of the substrate, and the surface of the substrate is washed with distilled water. It is preferable to coat by using The standard application amount varies depending on the type of substrate, application time, and climatic conditions,
