着剤の製造方法に関する。Description: TECHNICAL FIELD The present invention relates to a method for producing an adsorbent for efficiently removing odorous components, particularly malodorous components.

大きな問題となったが、最近は悪臭が快適さを損うとい
う理由でクローズ・アップされている。(Prior Art) The air pollution problem has been discussed for a long time as a cause of destruction of the natural environment and deterioration of the living environment. The recent trend is
With the improvement of living standards, there is an interest in improving habitability in everyday living spaces. For this reason, the destruction of the natural environment due to the toxicity of air pollutants has been a major issue in the past, but recently it has been highlighted as a reason that bad odors impair comfort.

の良い除去技術が必要とされている。Generally, the malodorous components are ammonia, trimethylamine,

これらの方法のうち、吸着法以外は比較的大きな事業場

や一般家庭には向いていない。これは装置が大きく操作
が複雑な上、危険な薬品を使用する等の理由による。Known methods for removing such malodorous components include a chemical cleaning method using an acid or an alkali, an adsorption method using an adsorbent, an oxidation method using a catalyst or an oxidant, a combustion method, and the like.
Of these methods, the methods other than the adsorption method are suitable for treating a large amount of air in a relatively large business site and are not suitable for small business sites or general households. This is because the device is large and complicated to operate, and dangerous chemicals are used.

吸着法は吸着剤として代表的な活性炭のほかゼオライ

とらないため、小事業場や一般家庭に向いているが問題
点も多い。In the adsorption method, zeolite, alumina, etc. are used as the adsorbents in addition to typical activated carbon, and because it is easy to operate and does not take up space, it is suitable for small businesses and ordinary households, but there are many problems.

いの中心成分である。Granular activated carbon has been used for a long time, and recently, activated carbon fibers have been developed to improve the adsorption performance, but the effect of removing polar substances such as ammonia and trimethylamine is not so high. These malodorous components are the main components of toilet odor and rotten fish odor, which are often problems in general households.

い。An ion exchange resin is mentioned as a special adsorbent. Ion exchange resins include cation exchange resins and anion exchange resins, which are basic gases (ammonia, trimethylamine, etc.) and acidic gases (hydrogen sulfide, hydrogen chloride, etc.), respectively.
However, since the shape is a bead, the method of use is limited to the filling method, and the surface area is small, so the reaction rate is not fast.

は言い難い。(Problems to be solved by the present invention) In order to improve the above problems in the ion exchange resin, gas adsorption utilizing the size of the surface area and the fast reaction rate, which are the features of the fiber, by using a fibrous ion exchanger. Agents have been proposed. However, all of these are merely manufactured as short fibers, and are rather close to powders, so that operability is extremely poor. It is hard to say that the other advantage of being fibrous that molding is easy is fully utilized.

ゲン化ポリオレフィン系のものが本発明には適している
が、この範囲に限定されるわけではない。As the organic polymer compound, a polyolefin-based compound or a halogenated polyolefin-based compound is suitable for the present invention, but is not limited to this range.

また、有機系高分子化合物の形状は繊維状が適してお

ある織布や不織布が特に適している。The organic polymer compound preferably has a fibrous shape, and can be either short fibers or long fibers, and a woven fabric or a nonwoven fabric, which is a molded body of fibers, is particularly suitable.

能である。After irradiating the organic polymer compound with ionizing radiation, a polymerizable monomer having an ion-exchange group and / or convertible to an ion-exchange group is graft-polymerized. There are two types, the case of and the case of steam, and the former is called liquid phase graft polymerization and the latter is called gas phase graft polymerization, and both are possible as means of the present invention.

である。Compared with liquid phase graft polymerization, vapor phase graft polymerization can remove the unreacted monomer after completion of the reaction simply by reducing the pressure, and thus the washing step is easy. In particular, as in the case of the fibrous woven or non-woven fabric used in the present invention, gas-phase graft polymerization is economically extremely advantageous for the reaction which has good liquid retention and is difficult to wash. Furthermore, in the gas phase graft polymerization, the reaction proceeds concentrating near the surface of the base material, so in the case where the diffusion rate from the surface is rate limiting such as gas adsorption, the gas adsorption rate is Graft polymerization is more advantageous.

法を用いることができる。Examples of the polymerizable monomer having an ion exchange group include those having a carboxyl group such as acrylic acid and methacrylic acid, those having a sulfone group such as sodium styrenesulfonate, and those having anion exchange properties such as arylamine. There are acrylonitrile, acrolein styrene, chloromethyl styrene, glycidyl methacrylate, vinyl pyridine and the like as the polymerizable monomer that can be converted into an ion exchange group, but the present invention is not limited to this range. A known method can be used for conversion into an ion exchange group.

The OH type and / or salt type of lower-grade amino groups are suitable. Depending on the method of use, it is possible to appropriately select whether to use a single ion-exchange group or a combination thereof.

されればガス成分の除去も同時に行える素材となる。As described above, according to the present invention, it is possible to produce a gas adsorbent having an ion-exchange group for both short fibers and long fibers, which is molded and used for small businesses and general households. It is easy to manufacture a compact deodorizing device that can be used. In particular, woven fabrics and nonwoven fabrics are used by themselves for removing fine particles, but if ion-exchange groups are introduced according to the present invention, gas components can be simultaneously removed.
