だ解決されていない。In recent years, photocatalysts have been used to decompose dirt, deodorize,
Various uses have been proposed for use in imparting various functions such as antibacterial, harmful component decomposition, air purification, and the like, and studies have been made on the use of photocatalysts in filters for the purpose of imparting the above-mentioned various functions. However, there has not yet been proposed a photocatalyst-based filter that has been satisfactorily and sufficiently provided with the above-mentioned various functions. In other words, needless to say, the photocatalyst cannot show its photodegradation activity unless it is irradiated with light, so if the filter is made two-dimensionally thin so that the photocatalyst can be easily irradiated with light, the photocatalyst and The contact with the fluid to be treated becomes insufficient, and the above functions are not sufficiently imparted to the filter. On the other hand, if the filter has a three-dimensional thickness in order to ensure sufficient contact between the filter and the fluid to be treated, light generally does not easily reach the three-dimensional thickness direction, and the photocatalytic activity of the photocatalyst is sufficient. And the above functions are not sufficiently imparted to the filter. As described above, in the use of a photocatalyst for a filter, the problem of ensuring sufficient contact between the fluid to be treated and the filter and the problem of sufficiently irradiating the photocatalyst to sufficiently exert its photocatalytic activity are contradictory. This conflicting issue has not yet been resolved.

The present invention has been completed by finding out what can be achieved. That is, the functional filter according to the present invention is characterized in that a web-like metal long fiber aggregate is coated with a photocatalyst. In the present invention, since the base of the filter is a web-like aggregate made of long metal fibers, unlike the case where the base is made of an organic material, it is not decomposed by the photocatalytic function and is nonflammable. It can be used in an environment where there is a high risk of fire such as a kitchen. In addition, since there is also reflection of light by long metal fibers, even if the filter has a three-dimensional thickness, light can reach the three-dimensional thickness direction, ensuring sufficient contact between the photocatalyst and the fluid to be treated. In addition, the photocatalyst activity of the photocatalyst can be sufficiently exhibited.

It refers to a state of being gathered in a cotton-like or net-like shape, or being woven into a cloth-like or sheet-like shape. The thickness of the web-like metal continuous fiber aggregate can be appropriately selected as needed, but generally, 10 to 100 mm is appropriate. The long metal fibers constituting the web-shaped long metal fiber aggregate are elongated fibers of stainless steel, brass, copper, aluminum, nickel, titanium, tantalum or other metals, and preferably have a diameter of 50 to 100 μm. Also,
Various cross-sectional shapes such as a rectangular shape, a circular shape, and a star shape can be used. Among them, fibers having a rectangular cross section are bonded to each other because the faces of the fibers and the corners are in contact with each other. And the photocatalyst is coated on a flat surface, so that the photocatalyst is more easily supported. As a method for producing long metal fibers, conventionally known methods such as a method of drawing can be used. Among them, a method of winding a thin metal sheet of a material into a coil shape and cutting it thinly with an appropriate cutting tool from the end face thereof. Is preferably used because a fiber having a rectangular cross section can be obtained and mass production can be performed at low cost. An example of such a metal long fiber is Bekinit (trade name) manufactured by Bekinit Co., Ltd.

られる。As described above, one of the specific film-forming components used in the coating composition is an organopolysiloxane as a main component, and an organosiloxane having a functional side chain as a crosslinking agent and a curing catalyst. (Hereinafter abbreviated as "organopolysiloxane composition"). In this organopolysiloxane composition, the organopolysiloxane as a main component preferably has a methyl group or a phenyl group. As the crosslinking agent, an organosiloxane having a functional side chain such as an alkoxy group, an acyloxy group, and an oxime group is preferable. As the curing catalyst, an organic compound containing a metal such as Zn, Al, Co, and Sn and a halogen are preferable. The organopolysiloxane composition preferably contains a silicon component in an amount of 40% or more in terms of SiO 2 , and does not contain a solvent, water or a hydroxyl group. Also,
The organopolysiloxane composition cures even when heated at low temperature or dried at room temperature to form a hard ceramic coating having excellent adhesion. Further, the curing mechanism is such that the functional group of the organopolysiloxane of the main agent is first hydrolyzed by moisture in the air to be changed to a hydroxyl group, and then the hydroxyl group of the organopolysiloxane is converted to the hydroxyl group of the crosslinking agent organosiloxane. It is considered that a functional group is attacked and a dealcoholization reaction is caused by the action of a curing catalyst to form a cured polysiloxane as a polymer compound having a three-dimensional structure. It becomes a metal alkoxy condensate by the so-called sol-gel method. Examples of such organopolysiloxane compositions include heatless glass (HEA) sold by Homer Technology Co., Ltd.
TLS GLASS) (trade name).
If necessary, the organopolysiloxane composition may be, for example, a silicone resin having an intermediate structure between inorganic and organic in which a siloxane bond has a three-dimensionally extended network structure and one methyl group bonded to a silicon atom. Other formulations, such as microparticles, can also be added. Examples of the silicone resin having an intermediate structure between inorganic and organic include Tospearl (trade name) sold by Toshiba Silicone Co., Ltd.

Although the actual molecular structure is complex, it is an oligomer having a number average molecular weight of several thousand containing many irregular cyclic parts. This perhydropolysilazane is converted into ceramics by firing after coating on the surface of the substrate, and is converted into silica glass (SiO 2 ) when fired in air or an atmosphere similar thereto. Examples of the organic solvent include aromatic hydrocarbon solvents such as benzene, toluene, and xylene, among which xylene is preferably used. The concentration of perhydropolysilazane in the organic solvent solution can be appropriately selected as needed. However, if the concentration is high, it becomes syrupy and poor in workability, so that it is in a range having an appropriate viscosity. Examples of such perhydropolysilazane include Tonen polysilazane (trade name) manufactured by Tonen Corporation. Further, a filler such as magnesium oxide and silicon carbide can be added to the organic solvent solution of perhydropolysilazane, if necessary.
