Photocatalyst Co 1 tee A Tongue agent constituent and photocatalyst support structure
Technical field :
growth control of the present invention, antifouling, clean water, deodorization, sterilization, effluent treatment, a moisture solution, and an alga -- and -- each -- In order to manufacture the photocatalyst support object used for a seed chemical reaction etc., and the photocatalyst support object It is related with a Co 1 Tyng agent constituent. In particular, they are the bottom of the environment of heat and high humidity, and Arc-proof. The Li nature requires. A photocatalyst support object usable also at the outdoor environment carried out, and photocatalyst coatee It is related with a Tongue agent. Background art :
Various carrier quality of the materials which support a photocatalyst are proposed. For example, (A) 2 ♪ Rossel A sirloin, glass, poly chlorination Bulle, and Plastic, Nay Light transmittance state substances, such as Ron, methacrylic resin, and polypropylene (Provisional-Publication-No. 6 2 -- 6 6 8 6 1) (B) Poly Prop The Wren textiles and Serra Mick (Provisional Publication No. 2 -- 6 8 1 9 0), (C) glass, and Serra Mick, nylon, and bitter taste There are Lil, polyester (Provisional Publication No. 5 -- 3 0 9 2 6 7), etc. Deer What carries out and makes an organic matter a subject in these quality of the materials, It is the Touch when a photocatalyst is supported. An organic matter being disassembled by intermediation operation or deteriorating has been reported. Durability. A problem is Oh (Fumiaki Otani, polymer processing 4 2 volume, No. 5, P 1 8 (1 9 9 3), Seino Education, and "titanium oxide" Gihodo Shuppan Co., Ltd., P 1 6 5) to a sex. .
Carrier materials are glass and Serra. In the case of inorganic substances, such as Mick it is support about a photocatalyst if organic polymers resin is used for adhesives in order to carry out -- a photocatalyst particle surface -- resin -- -ed -- catalyst activity not only falling, since it is reversed but power, and this resin -- a photocatalyst operation -- decomposition degradation -- Occurrence The problem arose in that carry out and a photocatalyst exfoliates etc. and endurance.
Then, when carrier material is a heat-resistant inorganic substance, Spa where an organic matter does not remain at all Buddha The ring method (Provisional-Publication-No. 6 0 -- 0 4 4 0 5 3) The application 1 calcinating method of organic Chinese 1 A (Provisional Publication No. 60 -- 1 1 8 2 3 6) Methods, such as the spray 1 calcinating method of Chi Tha D A Titania sol (Provisional-Publication-No. 0 5 -- 2 5 3 5 4 4), are adopted. however, method [ of these ], and carrier top in order to give adhesiveness with generation of photocatalyst particles, crystallization, and a carrier -- high temperature support of that calcination is required and a large area -- it can do -- To it is -- foolish Power and manufacture Kos A -- very much -- high -- There was a problem called There.
They are adhesives in order to support a photocatalyst on glass fiber paper. It carries out and is metal oxide sol. The method of using (Provisional Publication No. 5 -- 3 0 9 2 6 7) is proposed. However, Thilly Caso The adhesive strength of metal oxide sol, such as Le, is Hua. Since it is what is depended on A . A deer and Wharska It is very weak (the phi Nozera mix 1st volume p 2 1 6* 2 2 3 1 9 8 0), adhesiveness and alkali resistance are insufficient -- the baking processing by high temperature is required again it is -- Or -- it carries out -- thermal decomposition -- Occurrence Applicable to all the carriers containing Shabby general-purpose resin It was not a thing.
On the other hand, he is Thilly about photocatalyst powder. Example smell supported to metal oxide gels, such as power and argillite The, Adsorbent of a carrier It is Propionaldehyde by the effect to carry out. Photocatalytic degradation of Degas If a reaction is promoted with the report carried out (symposium" the latest deployment "of a photocatalytic reaction proceedings, 1 9 9 4, an optical functional-materials study group, 2 - 1 1, p .3 9). however -- like this -- Maintain high catalyst activity for the photocatalyst uniformly distributed in the metal oxide gel carried out. There is no report referred to as having acquired the photocatalyst support object excellent in adhesiveness and alkali resistance as [ It was ]. it was .
He is Thilly about a photocatalyst. The compound of a mosquito system, for example, Thilly, Power Sol y co mouth I DALCY Rika, Silicon alkoxy The hydrolysis product of Do, and polyorgano Shiroki Sun etc. are used. A carrier will be made to paste directly. The trial to carry out is mostly. It is made. (Provisional-Publication-No. 4 1 7 4 6 7 No. 9 gazette) Provisional Publication No. 6 -- 2 9 6 8 7 No. 4 gazette and Provisional Publication No. 7 1 7 1 4 0 No. 8 gazette. However, in any case, it is 5% of the weight of carbonic acid Na. It is 2 to thorium solution. It is made to contact for 4 hours. A surface photocatalyst layer is corroded, and it * Detaches, and is J I S K 5. 4 0 It is specified to 0. Al resistance power It is a failure in the Li examination and Oh.
In addition, (Provisional-Publication-No. 6 - 3 1 56 1 4) as which the method of fixing a photocatalyst by a fluoro-resin is also proposed. however, a fluoro-resin is firm in being not only expensive but photocatalyst particles in order to paste up -- a catalyst particle surface -- many -- covering by a fluoro-resin -- stripes A thing is required. it is -- as a result -- falling compared with the time of catalyst activity and powder -- stripes Problem of saying -- When. It is Off about a photocatalyst. List Motoki fat and polyorgano Difficulty resolvability binders, such as Shiroki Sun It mixes and is support Learn more to a base. There is tried Example (E P -- 0 6 3 3 0 6 No. 4 gazette). Adhesive resistant power It is insufficient for solution of practical subjects, such as the Li nature. Provisional Publication No. 8 -- 1 6 4 3 3 In No. 4 gazette, it is i*5. 0 Oxidization Chita of 0 n m A particle A child and Thilly Conte ♪ la alkoxy It consists of partial hydrolysis output of Do, and a solvent. Although the constituent for photocatalyst coat formation is indicated, light which formed membranes using this constituent a catalyst film -- 5% of the weight of carbonic acid Na ♪ Lyme solution -- 2 after dipping for 4 hours -- * Separation of a catalyst film it accepts -- Aruka-proof the Li nature is insufficient -- Oh.
a photocatalyst is supported on a carrier -- solve in order to use it in the environment of the outdoors or heat and high humidity Subject which Me does not become If it carries out, the following three points are mentioned.
namely
1 . Adhesiveness of Photocatalyst Film and Carrier is Good,
2 . It Does Not Fall by Supporting Photocatalyst Activity of Photocatalyst Film on Carrier,
3 . -- the supported photocatalyst film maintains adhesive strength over a long period of time -- maintaining endurance It is To.
furthermore -- the case where it is used by outdoor environment -- Paint co 1 tee for outer walls a Tongue agent etc. -- a demand -- Being done -- like and Arc-proof The Li nature is important. In particular, it is used on an outer wall or the outskirts of it. A case is concentrated. It oozes out from a lied, mortar, and a tile masonry joint, and is To. Arka Li ingredient Since contact is not avoided, it meets. Al power carried out It is indispensable to bear Li solution and it is Ah. To. Therefore, J I S which is a J I S standard of a common paint -- K 5 4 0 Also in 0, it is five-fold. Quantity % carbonic acid Na Ruka-proof which uses Rum solution The Li examination is specified. From book Growth control of Ming, antifouling, clean water, deodorization, sterilization, effluent treatment, a moisture solution, and an alga, and various kinds Usable to a chemical reaction, and the structure which supported the photocatalyst which can solve the above-mentioned section * -- Co 1 tee for calling and manufacturing the structure Thing aiming at providing a Tongue agent it is .

With as a result, the thing set in the dark place which does not irradiate with light, the probability of survival of coliform bacillus -- after 1 hour -- nine after 2 % and 2 hours -- nine after 1 % and 3 hours -- nine as opposed to having been 1 % -- bra Kakura what irradiated with Ito's light -- the probability of survival of 1 hour after -- 5 after 2 % and 2 hours -- two after 9 % and 3 hours -- one It was 1 %. It is the probability of survival of coliform bacillus which irradiated with light of a fluorescent light. After 1 hour After 7 6 % and 2 hours After 54 % and 3 hours It is 2 2 %. a dark place -- . High antibacterial properties were shown compared with a sample of a photocatalyst structure which was. Comparative example 1 8
A liquid it carries out -- oxidization Chita A powder (Product P made from Japanese Aerosil -- 2 5) 1 0 Zero copy and isopropanol 9 0 Zero copy and Zirconium tetraoxide (T B Z R Made from Nippon Soda ) 1 0 The liquid which consists of zero copy was prepared. B liquid carrying out -- iso -- proper Knoll 9 0 Zero copy and ethanol 2 0 Zero copy and water 1 0 The liquid which consists of zero copy was prepared. poly putting A liquid into the beaker made from ethylene -- 1 0 c m angle -- Torn nonwoven fabric [ (Product Glass fiber nonwoven fabric S A S / made from Oh Li The best / - 0 3 0) ] -- dipping three sheets -- 3 for 0 minute -- silently -- Machine -- Vibration is carried out -- A liquid was made to permeate a nonwoven fabric enough They are A liquid to extraction, and Ho mouthful 1 about a nonwoven fabric. It is 3 to B liquid put into make beaker 1. It dipped for 0 minute. taking out a nonwoven fabric from B liquid -- 6 the normal pressure after drying with a vacuum dryer by 0 °C for 8 hours -- 1 5 it dries by 0 °C for 1 hour -- Photocatalyst support object It carried out.
It is Serothe 1 the result of having stuck the Scotch tape on this photocatalyst support object, and having done * Separation test. A lot of photocatalyst powder had adhered to the A adhesive face. this photocatalyst support object -- five-fold sodium carbonate solution of quantity % -- 2 if it washes with distilled water after dipping for 4 hours -- rinse water it becomes cloudy -- it turned out * that the photocatalyst has detached. Example 1 -- 4 4*5 0
Using the Oxy zirconium nitrate liquid shown in (Z -- 6) and (Z -- 7), the result shown in The 4 table was obtained. Photocatalyst activity, adhesion, and Arc-proof The Li nature, endurance, and optical penetration The sexual good thing was obtained. The rate of Hayes is also as low as below 5 %, and the transparency of a rate is high. It was.
Like and carrier material which were shown in the above example It carries out and they are a product made from polymer 1, glass, and metal. A film is also spread. They are the Bako 1 A method and Di the case where it supports to a board. The A method and Grad Beer seal The thing of the characteristic outstanding by the various forming-membranes methods, such as the Printing method and the spraying method, was obtained.
5 of the sum total of the photocatalyst layer of a structure, and an adhesion layer which supported the photocatalyst 5 All the lights of 0 n m It is 7 although it changes with line transmissivity, thickness of a photocatalyst layer, etc. They are an example and good Up in more than 0 %. It carries out, and it is and 5% or less of thing of high transparency is obtained for the thing with light transmission nature, or the rate of Hayes. Industrial applicability
Photocatalyst structure of the present invention, A photocatalyst has pasted a carrier firmly. Photocatalyst activity Very high Moreover, a carrier deteriorates by photocatalyst operation, Squirrel from which a photocatalyst was desorbed There is no To and it can use it also under light irradiation for a long period of time. Arc-proof Li nature That experimental evaluation is also good and Sunshine Promotion by A power 1 Boner 1 Couza 1 Me - Tar Under [ since high adhesion is maintained after the weather resistant test ] the environment of heat and high humidity An usable photocatalyst support object can be acquired under outdoor environment. visible light -- Transparent Since the transparent thing which carries out a fault is also obtained, the handle of a carrier is harmed. There are nothings and it supports a catalyst. things are made -- fanciness is spoiled to broad carriers, such as general-purpose resin and a natural fiber There are nothings.
