Description

【発明の詳細な説明】 本発明は吸水性を有し、しかも消臭能を有する吸水剤に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water-absorbing agent that has water-absorbing properties and also has deodorizing ability.

コール変成物、架橋インブチレン−無水マレイン酸共重
合体等が知られている。Conventionally, as water absorbing agents, hydrolysates of starch-acrylonitrile-covered raft copolymers, neutralized products of starch-acrylic acid graft polymers, cross-linked carboxymethyl cellulose,
acrylic acid ester-vinyl acetate copolymer compound;
Partially neutralized polyacrylate crosslinked products, crosslinked polyvinyl alcohol modified products, crosslinked imbutylene-maleic anhydride copolymers, etc. are known.

近年、これらの吸水剤が生理用ナプキン、紙おむつ等の
衛生材料に使われてきている。しかし、これらの吸水剤
を衛生材料に使用した場合、尿や血液は吸収するも１の
の、これらに起因する悪臭の為に使用時の不快感はぬぐ
いきれない。In recent years, these water absorbing agents have been used in sanitary materials such as sanitary napkins and disposable diapers. However, when these water-absorbing agents are used in sanitary materials, although they absorb urine and blood, the unpleasant odors caused by these agents cannot eliminate the discomfort during use.

この悪臭を除去するために、一部では活性炭やその他の
脱臭剤を併用しているが、消臭能がいまだ十分ではなく
、さらには紙おむつや生理用ナプキン等の製造工程が複
雑にガつたシ、コストが高くついたυ等の欠点がおる。In order to remove this bad odor, activated carbon and other deodorizing agents are used in some cases, but the deodorizing ability is still insufficient, and the manufacturing process of disposable diapers and sanitary napkins is complicated and complicated. There are drawbacks such as high cost and υ.

れている。As such, there is currently no known material that has both excellent water absorption and powerful deodorizing ability, and is used for sanitary materials or other industrial applications that require both moisture absorption and deodorization functions. It is hoped that an excellent water-absorbing agent with strong deodorizing ability will emerge.

この様な事態に鑑み、本発明者らは鋭意研究を重ねた結

提供するものである。In view of this situation, the present inventors have conducted extensive research and have arrived at the present invention. That is, the present invention uses water absorbent resin (a
) and a leaf extract (b) of a plant of the Camellia family.

ポリアクリル酸塩架橋体が好ましい。The water-absorbing resin (a) used in the present invention is water-based, and includes, for example, a hydrolyzate of starch-acrylonitrile graft copolymer (for example, disclosed in Japanese Patent Publication No. 49-43395), starch-acrylic acid Neutralized products of graft polymers (e.g., Japanese Patent Publication No. 46199/1983, Japanese Patent Publication No. 55/1983)
21041), saponified products of acrylic acid ester-vinyl acetate copolymer (disclosed in Japanese Patent Publication No. 53-134),
(Disclosed in Publication No. 95, Japanese Patent Publication No. 55-19243),
Cross-linked polyvinyl alcohol modified products (e.g. JP-A-54-
20093), partially neutralized polyacrylate crosslinked products (for example, JP-A-55-84304, JP-A-56-93716, JP-A-56-161408, JP-A-58- 71907), crosslinked inbutylene-maleic anhydride copolymer (disclosed in JP-A-5
6-36504), etc. can be used. Among these, partially neutralized crosslinked polyacrylates are preferred in terms of water absorption and deodorizing ability.

等の成分を含むが、その消臭作用機構は明らかでない。The leaf extract (b) of the Camellia family plant used in the present invention is
For example, it is extracted from the leaves of camellia, tea plants, sasanqua, sakaki, hisakaki, etc. with organic solvents such as alcohols and ketones, water, or mixed solvents thereof. The leaf extract (b) of a plant belonging to the Camellia family has a stronger deodorizing effect than extracts from other plants. The above extract (b) contains components such as flavonols, flavanols, organic polymers, and tannic acid, but its deodorizing mechanism is not clear.

では消臭効果に差はなく、経済的にも不利である。The amount of the leaf extract (b) of the Camellia plant to be used is preferably 0.01 ppm or more based on the weight of the water-absorbing resin (,), and can be arbitrarily selected depending on the purpose of use. If the content of the leaf extract (b) of a plant belonging to the Camellia family is less than 0.01 ppm, the resulting water absorbing agent will have a weak deodorizing effect, which is not preferable. As described above, the performance is normally exhibited at 0.01 ppm or more, but when the water absorbing agent of the present invention is used for diapers, sanitary cotton, etc., the amount of the leaf extract (b) of the Camellia family plant to be added should be adjusted to increase the water absorbency. resin(,
) to o,ooot weight percent (1ppm)
-10 weight percent is preferable, and if o, ooo is less than 1 weight percent, a bad odor may be observed if there is a large amount of absorbed liquid such as urine during use. If the amount exceeds 10% by weight, there is no difference in the deodorizing effect and it is economically disadvantageous.

ら本発明の吸水剤を得るには、例えば次のような方法に
よることができる。The water-absorbing agent of the present invention can be obtained from the water-absorbing resin (2) and the leaf extract (b) of a plant belonging to the Camellia family, for example, by the following method.

（１）吸水性樹脂（ａ）にツバキ科植物の葉抽出物（ｂ

では、一部アンモニアを吸収することは知られている。The water absorbing agent of the present invention has far superior performance compared to conventionally known water absorbing agents. That is, the water-absorbing agent of the present invention absorbs and swells body fluids such as urine, menstrual blood, and sweat, as well as liquids generated from garbage, etc., and deodorizes bad odors generated from these excreta and liquids. , this deodorizing effect lasts for a long time. It is known that conventional water absorbent resins alone absorb some ammonia.
