Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind mounted on a window glass or the like, and more particularly to a method for removing germs and molds, dust, dust and the like adhering to the surface and purifying and deodorizing indoor air. The present invention relates to a photocatalyzed blind having the same.

[0002]

2. Description of the Related Art Conventionally, window glasses for general homes, stores, public facilities, etc. have been equipped with blinds for shielding or blinds.

As a general blind, a slat is raised and lowered by manipulating a code for lifting and lowering, and a venetian blind is used in which the angle of the slat is changed by an angle adjusting lever to adjust the amount of incident light.

[0004]

However, the conventional blind is intended to function as a sunshade for blocking sunlight radiated from a glass window, and as a blindfold for shielding indoor conditions from the outside. Was limited.

[0005] Further, the general-purpose Venetian blind has a disadvantage that dust and dust in the room easily adhere to the surface of the slat. Furthermore, the work of removing slats is very troublesome, requiring a lot of time and effort.

In view of the above, the present invention provides a photocatalyst capable of automatically removing various bacteria and molds, dust and dirt attached to the surface of the slat, and purifying and deodorizing indoor air. To provide blinds.

[0007]

A blind provided with a photocatalyst according to the present invention for solving the above-mentioned problem is provided on a window glass or the like for a blind or a blind to be attached to a blind or a blind. , A peroxotitanic acid (PTA) solution and a peroxo-modified anatase (PA) sol.

[0008] Peroxotitanic acid (P
By coating the TA) solution and the peroxo-modified anatase (PA) sol, a photocatalyst can be formed on the slat surface. As a result, sunlight and sunlight illuminated from the window glass can automatically remove germs and mold, dust, and dirt attached to the surface of the slat, and keep the blinds clean. Can be kept.

[0009] Further, the air in the room equipped with the blinds can be simultaneously purified and deodorized by the sunlight and the irradiation light.

[0010]

Next, an embodiment of a blind provided with a photocatalyst according to the present invention will be described with reference to the drawings. FIG. 1 is a front view of a blind with a photocatalyst partially cut away, FIG. 2 is a perspective view of the blind partially cut away, FIG. 3 is an enlarged sectional view of the blind, and FIG. Respectively shows the use condition of the blind to which the photocatalyst of the present invention has been applied.

The blind 1 includes a plurality of slats 2 that are horizontally laid and a cord 3 for raising and lowering the slats 2.
And an angle adjusting lever 4 for changing the angle of the slat 2 and adjusting the amount of incident light.

The slat 2 is coated with a peroxotitanic acid (PTA) solution 10 and a peroxo-modified anatase (PA) sol 11.

Peroxotitanic acid (PTA) solution 10
Is an amorphous type that is synthesized from an inorganic titanium solution and changes to titanium oxide at 250 ° C. or higher.

The above peroxotitanic acid (PTA)
The solution 10 is crystallized into anatase at a low temperature of 250 ° C., and has high density and high adhesion properties, so that it is possible to coat a material having no heat resistance. Further, there is an advantage that the stability is very high and the handling is easy.

The above peroxotitanic acid (PTA)
The solution 10 has an application function such as an antibacterial film, an antifouling film, a superhydrophilic film, and a mixed film with other particles, and can be coated on a material such as glass, porcelain, or metal for other uses. .

Peroxo-modified anatase (PA) sol 1
Reference numeral 1 denotes a dispersion liquid containing anatase ultrafine particles, which has characteristics such as low density, relatively high photocatalytic function, and catalytic function in drying.

In addition, the peroxo-modified anatase (P
A) The sol 11 has application functions such as air purification, deodorization, water purification, antibacterial and the like, and can be coated on a wide range of materials such as glass, ceramics, metal, paper and cloth for other uses.

The peroxo-modified anatase (P
A) Since the titanium oxide particles of the sol 11 are very small and can be coated at a low temperature, a high surface area can be maintained even after a film is formed.

The surface of the slat 2 of the blind 1 is sprayed with a peroxotitanic acid (PTA) solution 10 for coating, and after drying, the upper surface of the slat 2 is sprayed with a peroxo-modified anatase (PA) sol 11 to coat.

A peroxotitanic acid (PTA) solution 10 and a peroxo-modified anatase (P)
A) A photocatalyst can be formed on the blind 1 by coating the sol 11.

Further, the film made of the peroxotitanic acid (PTA) solution 10 and the peroxo-modified anatase (PA) sol 11 is not peeled off at all by a method such as peeling off a resin or a cellophane tape, and the dried film is made of water. Never redissolved in

Further, as shown in FIG. 4, sunlight A entering from the window glass 5 and illumination light a emitted from indoor lighting fixtures cause various bacteria and molds attached to the surface of the slat 2, and Dust and dirt can be automatically removed, and the blind 1 can always be kept clean.

In addition, the indoor air around the blind 1 is purified by the sunlight A and the illumination light a, and at the same time, living odors such as mold and cigarette odors can be deodorized.

[0024]

As described above, the blind provided with the photocatalyst of the present invention has the following effects as described above.

By coating the slat portion of the blind with a peroxotitanic acid (PTA) solution and a peroxo-modified anatase (PA) sol, a photocatalyst can be formed on the slat surface, so that light is incident from the window glass. Sunlight and illumination light from indoor lighting fixtures can automatically remove germs, mold, dust and dirt on the slat surface, and keep the blinds clean at all times. Can be.

Further, the indoor air around the blinds can be purified by the sunlight and the illumination light, and at the same time, living odors such as mold and cigarette odors can be deodorized.
