Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a balloon having a deodorizing function for purifying air, which can be used for toys, advertisements and viewing.

[0002]

2. Description of the Related Art Conventionally, as a method of removing a bad odor or an unpleasant odor in a room such as a toilet, a living room, an office, etc., conventionally, a deodorant is forcibly brought into contact with a deodorant component using a deodorizer equipped with a deodorizer and a fan. There is known a method of removing and removing.

[0003]

However, in the above method, the space velocity (SV) increases as the fan air volume increases, and the deodorizing efficiency does not increase with respect to the electric power consumption. And it is difficult to obtain a sufficient deodorizing effect. There was also a problem of noise caused by fans.

[0004]

Means for Solving the Problems The present inventors have completed the method for eliminating the above-mentioned problems, eliminating the need for a special device, and easily removing the odor in the room. That is, the present invention is a balloon having a deodorizing function in which a gas lighter than air is injected and floats in the air, and a sheet-like deodorizing material is fixed to the balloon.

[0005] The sheet-like deodorizing material fixed to the balloon is:
(A) metal and / or metal oxide particles, (b) adsorbent particles, (c) thermoplastic resin particles, and (d) a fibrous base material of a gas-permeable sheet, wherein the metal and / or metal oxide is contained. Particles (a) and adsorbent particles (b) are thermoplastic resin particles (c)
A sheet bonded to the surface at a contact portion between the particles and the thermoplastic resin particles (c) bonded to the fibrous base material (d) of the breathable sheet is preferably used.

In the present invention, helium, hydrogen and the like are used as the gas lighter than the air injected into the balloon, and helium is preferably used from the viewpoint of safety. When a lighter gas such as helium is injected into the balloon, the balloon floats in the air. The balloon is provided with a deodorizing function so that the balloon floats itself and efficiently removes offensive odor components. The deodorizing function can be imparted to the balloon by a method of attaching a thin sheet-shaped deodorizing material cut into an arbitrary shape to an appropriate place of the balloon, a method of covering the balloon with a bag-shaped deodorizing material, or the like. The fact that a thin and light sheet-like deodorizing material can be produced greatly contributes to the present invention.
Therefore, a sheet-like deodorizing material will be described below.

The two types of metal and / or metal oxide particles (a1 and a2) and the one type of adsorbent particles (b) maintain their shapes (shown in the figure as spherical shapes) while keeping the thermoplastic resin. The particles (c) are bonded to the surfaces of the particles at the contact portions of the particles, and the thermoplastic resin particles (c) are bonded to each other at the respective contact portions and are bonded to the fibers of the fibrous base material (d). It forms a sheet-like porous structure having a spread.

The sheet-like deodorizing material has a porosity of 50% or more, preferably 80% or more, and a specific surface area of 20 m ² /
g or more, a material having air permeability and capable of efficiently removing bad odors and harmful substances such as hydrogen sulfide, ammonia, formaldehyde, acetaldehyde, carbon monoxide and ozone is used. The thickness is preferably light and thin enough to float in the air by the buoyancy of the balloon, usually 1 mm or less, preferably,
Use the one with 0.5 mm or less. The sheet-like deodorizing material may be covered with a cover sheet having air permeability in order to prevent the surface from being stained or damaged.

The metal and / or metal oxide particles (a) in the sheet-like deodorizing material include manganese, copper, zinc,
There are particles of iron, vanadium, nickel, magnesium, aluminum, titanium, palladium, platinum, cerium, silicon and their oxides. Particles of these metal composite oxides may be used. As manganese oxide, M
There are nO ₂ , MnO, Mn ₃ O ₄ , Mn ₂ O ₃ and Mn ₂ O ₇ , among which MnO ₂ is preferably used. Examples of the copper oxide include CuO, Cu ₂ O, and Cu ₄ O, and among them, CuO is preferably used. One kind of these metal and / or metal oxide particles may be used, but two or more kinds may be used in combination to provide a function of purifying various kinds of harmful substances. Further, it may be used in the form of composite oxide particles. As a preferable example in the case of mixing two or more kinds, there is one containing manganese dioxide particles and cupric oxide particles.

The adsorbent particles (b) include activated carbon, zeolite, silica gel, sepiolite, hydroxyapatite, activated alumina and activated clay. The adsorbent particles carrying aluminum sulfate, iodine, ferrous sulfate, calcium phosphate, sodium carbonate, magnesium silicate, boric acid, phosphoric acid, ascorbic acid, tartaric acid, oxalic acid, tannic acid, gallic acid, etc. are also used. be able to. One type of adsorbent particles may be used, or two or more types may be used. Activated carbon includes vegetable carbon (coconut shell, almond shell, etc.), charcoal, bituminous coal, etc., as well as synthetic resin carbonaceous (phenolic resin, etc.), and any of them can be used.

As the thermoplastic resin particles (c), ultrahigh molecular weight polyethylene, polyethylene, polycarbonate,
Polyamide ABS resin, polyimide, polyvinyl chloride,
The particles are selected from polysulfone, polystyrene phthalate, polypropylene, cellulose acetate and the like. These thermoplastic resin particles are obtained by forming metal and / or metal oxide particles (a) and adsorbent particles (b) on the surface of the thermoplastic resin particles (c) without being covered with the thermoplastic resin layer. It has a role as a binder to bind at the contact part. Among the thermoplastic resin particles, ultrahigh molecular weight polyethylene is preferably used, and its average molecular weight (measured by a viscosity method) is about 1,000,000 to 9,000,000.

As the fibrous base material (d) of the breathable sheet, a fibrous base material having a porosity of 60% to 99% is used.
For example, glass woven fabric / non-woven fabric, plastic woven fabric / non-woven fabric of polyethylene, polypropylene, polyamide, polyester and the like, paper and the like.

The sheet-like deodorizing material comprises (a) metal and / or
Alternatively, a uniformly dispersed suspension is prepared by mixing metal oxide particles, (b) adsorbent particles, (c) thermoplastic resin particles, (e) a water-absorbent resin, and (f) water. Allowing a predetermined amount of the turbid liquid to be retained on (d) the fibrous base material of the breathable sheet;
The metal and / or metal oxide particles (a) and the adsorbent particles (b) are heated at a temperature not lower than the melting point of the thermoplastic resin and equal to or lower than the thermal decomposition temperature to remove the moisture, and the thermoplastic resin particles (c). And bonded to the fibrous substrate (d) via

The size of the thermoplastic resin particles (c) having a size occupying 50% or more of the adsorbent particles (b) on a weight basis and the average particle size of 20 to 150 μm are usually used.

The reason for adding the water-absorbing resin (e) is that the aqueous suspension of the mixed particles of the metal and / or metal oxide particles (a), the adsorbent particles (b) and the thermoplastic resin particles (c) is made uniform. It is for dispersing in. When the water-absorbent resin is added, the water-absorbent resin absorbs water and the viscosity increases, so that the suspension of the mixed particles is uniformly dispersed, and furthermore, the uniformly dispersed state is stably maintained for a long time. It is.

After a certain amount of the suspension is held on the fibrous base material, it is heated at a temperature not lower than the melting point of the thermoplastic resin and not higher than its pyrolysis temperature for a predetermined time. By this heat treatment, moisture is evaporated and removed, and the surface layer of the thermoplastic resin particles is softened to have a bonding force. The thermoplastic resin particles having a surface layer softened and having a binding force capture and bond the particles (a) and (b) on the surface thereof while maintaining the spherical particle shape, and form the thermoplastic resin particles ( c) bonding to the fibrous base material while bonding each other at a contact portion.
