- Japanese Unexamined Patent Publication No. 7-117408 Japanese Unexamined Patent Publication No. 7-117408
- a mixture obtained by mixing titanium peroxide with a photocatalyst using titanium peroxide as a binder Japanese Patent No. 2875993
- Japanese Patent No. 2875993 Japanese Patent No. 2875993
- the binders used in these mixtures are all inorganic binders, they have a disadvantage that they cannot be firmly adhered to the surface of the organic base material.
- the undercoat can improve the adhesion between the mixture and the organic substrate, since the mixture contains an inorganic binder, The film of the mixture formed on the surface of the alloy has poor toughness. Therefore, when the mixture is used for a flexible organic substrate, the coating may be separated from the organic substrate due to the bending of the organic substrate. For example, when the mixture is adhered to a cloth, the mixture falls off from the cloth during washing, so that the desired effect such as deodorization cannot be maintained.
- binders composed of curable resins such as melamine resin, epoxy resin, and fluororesin (Patent No. 3222192) and acrylics A binder comprising a resin emulsion has been proposed.
- the present invention has been made in view of the above conventional technology, and maintains the texture and flexibility of the organic base material, has excellent adhesion between the organic base material and the photocatalyst, and has the effect of the photocatalyst. It is an object of the present invention to provide a photocatalyst-containing base material capable of holding the substrate for a long time.
- the present invention relates to a photocatalyst-containing substrate obtained by attaching photocatalyst fine particles to a surface of an organic substrate with a resin binder containing a shellac resin.
- the photocatalyst-containing substrate of the present invention has one major feature in that a shellac resin is used as a resin binder.
- the shellac resin is used as the resin binder of the photocatalyst-containing base material, surprisingly, not only is the texture and flexibility of the organic base material hardly impaired, but also the organic base material is hardly impaired. Excellent adhesion between photocatalyst and photocatalyst An excellent effect that an effect such as a deodorizing effect by the odor can be maintained for a long period of time is exhibited.
- the photocatalyst-containing substrate of the present invention uses a silica resin as a resin binder, an excellent effect of suppressing the deterioration of such a coating is exhibited.
- the photocatalyst-containing substrate of the present invention solves all the problems of the prior art, and is expected to be used in a wide range of applications.
- the shellac resin used in the present invention is a natural resin obtained by purifying a resin (stick lac) secreted by Lacquerbug.
- Shellac resin is considered to be a natural condensation product in which oxycarboxylic acid mainly composed of arylic acid, kerosenic acid and the like is bonded to lactone, but its composition is not completely elucidated.
- Examples of the shellac resin that can be suitably used in the present invention include a purified shellac specified in JIS K 5909, a white rack specified in JIS K 5911, and the like.
- Shellac resin alone is a solid, and thus can be used, for example, as a solution dissolved in an organic solvent such as lower alcohol such as ethanol, or as an aqueous emulsion.
- photocatalyst examples include titanium dioxide, zinc oxide, and a composite oxide of titanium dioxide and zinc oxide. These photocatalysts can be used alone or in combination of two or more. Among these photocatalysts, titanium dioxide can be suitably used because of its high catalytic activity.
- the photocatalyst has a primary particle diameter of 250 nm or less, preferably 50 nm or less. Catalyst fine particles are desirable from the viewpoint of uniformly dispersing in the shellac resin and enhancing the catalyst activity.
- the photocatalyst can be used in the form of a powder or as an aqueous gel.
- Titanium dioxide aqueous gel is, for example, manufactured by Ishihara Sangyo Co., Ltd., trade name:
- the amount of photocatalyst cannot be determined unequivocally because it varies depending on the type of organic substrate and its application, but usually, it exhibits sufficient catalytic activity and retains the flexibility and texture of the organic substrate.
- the amount of the shellac resin is preferably 100 to 500 parts by weight, more preferably 50 to 400 parts by weight, per 100 parts by weight of the shellac resin.
- an aqueous sol of the photocatalyst and a shellac resin emulsion must be used, and a mixed solution in which both are mixed is used. preferable.
- this mixed solution is prepared, the mixed solution can be adhered to the organic substrate by, for example, a dipping method, a roll coating method, a spray coating method, or the like.
- the amount of photocatalyst adhered to the organic substrate cannot be determined unconditionally because it differs depending on the type and use of the organic substrate, but usually, sufficient catalytic activity is exhibited and the flexibility of the organic substrate. from the viewpoint to avoid impaired sexual and texture, 1 ⁇ 2 0 g / m 2, preferably after depositing the mixed solution 3 ⁇ 1 5 g / m 2 organic substrates is desirable that a By drying the organic base material, the photocatalyst and the shellac resin can be fixed to the organic base material.
- the organic substrate examples include an organic fiber substrate, a resin plate, a resin sheet,
- the present invention is not limited to only such examples.
- an organic fibrous base material is preferable from the viewpoint of adhesion between the photocatalyst and the shellac resin.
- the organic fibrous base material examples include a woven fabric such as a fabric made of organic fibers, a nonwoven fabric, a felt, and a knit, but the present invention is not limited to such examples.
- the fibers constituting the organic fibrous base material include, for example, natural fibers such as cotton, silk, hemp, wool, etc., regenerated fibers such as rayon, semi-synthetic fibers such as acetate, polyester fibers, acryl fibers, and nylon fibers. Examples include synthetic fibers such as polypropylene fibers. Among these fibers, natural fibers such as cotton and silk, polyester fibers, nylon and the like are preferable from the viewpoint of adhesion of the photocatalyst and the shellac resin.
- the thus obtained photocatalyst-containing substrate of the present invention does not impair the flexibility and feel of the organic substrate because the resin is used as a resin binder. It is firmly attached to the substrate. Further, the photocatalyst-containing substrate of the present invention exhibits a strong oxidizing power when irradiated with light, but since the oxidizing power hardly denatures the shellac resin, excellent photocatalytic activity is maintained over a long period of time.

- the obtained photocatalyst-containing substrate was placed in a container filled with 10 L of water, and hand-rubbed and washed in the container for 1 minute. Then, after drying the photocatalyst-containing substrate after washing in a box-type electric dryer at 100 ° C. for 1 hour, in the same manner as in the above “deodorizing property”, it is irradiated with ultraviolet rays, and for 30 minutes from the ultraviolet irradiation, The concentration of ammonia gas in the container after 1 hour and 2 hours was measured with a detector tube [No. 3La, manufactured by Gastech Co., Ltd.].
- titanium dioxide aqueous sol As a photocatalyst, titanium dioxide aqueous sol [Ishihara Sangyo Co., Ltd., trade name: STS-
- a cloth (basis weight: 650 g / m 2 ) made of 100% polyester fiber is cut into a size of 10 cm ⁇ 10 cm, and the obtained base material is cut into a box-type electric dryer at 100 °. After drying for 1 hour at C, the weight was measured. As a result, the weight of the substrate is 6. 36 g.
- this base material is immersed in the mixed solution obtained above, allowed to stand for 5 minutes, taken out of the liquid, and the weight of the mixed solution contained in the base material is equal to the weight of the base material.
- the substrate was squeezed strongly to obtain a photocatalyst-containing substrate. Thereafter, the photocatalyst-containing substrate was dried at 100 ° C. for 1 hour in a box-type electric dryer, and the weight was measured. As a result, the weight of the photocatalyst-containing substrate was 6.49 g.
- the amount of the photocatalyst attached to the obtained photocatalyst-containing substrate was 10.4 gZm 2
- the amount of the acrylic resin (resin solid content) was 2.6 g / m 2 .
- the photocatalyst-containing base material obtained in Example 1 was excellent in texture and deodorant properties, and retained its deodorant effect even after washing. This indicates that the photocatalyst is firmly attached to the photocatalyst-containing base material.
- Comparative Example 1 is an example in which a conventional binder was used, but the obtained photocatalyst-containing base material had good deodorizing properties at the initial stage, but was inferior in texture, and was difficult to wash. Since the deodorization property has been significantly reduced by performing It can be seen that the wearing strength is also poor.
- Example 2
- An ethanol solution having a shellac resin solid content concentration of 3.5% by weight and an aqueous sol of titanium dioxide [trade name: STS-0K, primary particle diameter of titanium dioxide: 7 nm, manufactured by Ishihara Sangyo Co., Ltd.]
- the mixture was mixed so that the content was 2% by weight and the shellac resin content was 0.5% by weight to obtain a mixed solution.
- the photocatalyst-containing base material of the present invention has a moderate flexibility based on the organic base material, has excellent photocatalytic adhesiveness, and retains the effects such as the deodorizing effect of the photocatalyst for a long period of time. Therefore, it can be suitably used for interior textiles such as clothes and curtains, floor mats, and automobile interior materials.
