本発明は、抗菌性を有する吸水性樹脂組成物の製造方法
に関し、特に吸水性樹脂表面に抗菌剤被膜を設けること
によって抗菌性を付与した抗菌性を有する吸水性樹脂組
成物の製造方法に関する。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a method for producing a water-absorbing resin composition having antibacterial properties, and in particular, to a method for producing a water-absorbing resin composition that has antibacterial properties by providing an antibacterial coating on the surface of the water-absorbing resin. The present invention relates to a method for producing a water-absorbing resin composition having antibacterial properties.
(従来の技術及び発明が解決しようとする課題)吸水性
樹脂を用いた吸水シートは、従来から、おむつ、生理用
品、食品用ドリップシート、結露防止材、ペット用シー
ト、農園芸資材など多種多様の用途に用いられている。(Prior art and problems to be solved by the invention) Water-absorbing sheets using water-absorbing resins have been used in a wide variety of applications, including diapers, sanitary products, drip sheets for food, dew prevention materials, sheets for pets, and agricultural and horticultural materials. It is used for this purpose.
この吸水シートは吸水性樹脂が吸水すると、吸水シート
の表面材も含水状態となり、そのため表面材の表面に黴
が生えたり、雑菌が繁殖しやすくなる。When the water-absorbing resin absorbs water in this water-absorbing sheet, the surface material of the water-absorbing sheet also becomes hydrated, making it easy for mold to grow on the surface of the surface material and for bacteria to propagate.
例えば、吸水性シートを食品用ドリップシートとして使
用した場合に、シートの表面に雑菌が生じると食品の鮮
度を劣化させ、又、おむつ、生理用品、シーツ等に使用
した場合には非衛生であり、更に、結露防止用シートに
使用した場合には、その表面の天井板、壁紙、建具等に
も黴が発生する等の問題点があった。For example, when a water-absorbent sheet is used as a drip sheet for food, the freshness of the food deteriorates if bacteria grow on the surface of the sheet, and it is unhygienic when used for diapers, sanitary products, sheets, etc. Furthermore, when used as a dew condensation prevention sheet, there were problems such as the formation of mold on the surface of the sheet, such as ceiling panels, wallpaper, fittings, etc.
かかる問題点を解決する方法として、吸水シートを製造
する際、吸水樹脂と共に抗菌剤を配合することが考えら
れるが(例えば、特開昭63−15654号)、吸水性
樹脂が吸水しても抗菌作用のない部分が多くあるため所
期の目的は達成できなかった。One possible way to solve this problem is to mix an antibacterial agent with a water-absorbing resin when manufacturing a water-absorbing sheet (for example, Japanese Patent Application Laid-open No. 15654/1983), but even if the water-absorbing resin absorbs water, the antibacterial agent will not be present. The intended purpose could not be achieved because there were many parts that did not work.
本発明は、かかる問題点を解消するため種々検討した結

体に抗菌性を付与することによって、上記問題点を解決
することを見出し、本発明を完成するに至ったもので、
本発明の目的は抗菌性を有する吸水性樹脂組成物の製造
方法を提供するにある。As a result of various studies to solve these problems, the present invention has found that the above problems can be solved by coating the surface of the water-absorbing resin with an antibacterial coating to impart antibacterial properties to the water-absorbing resin itself. This invention has been completed,
An object of the present invention is to provide a method for producing a water-absorbing resin composition having antibacterial properties.
(課題を解決するための手段)
本発明の要旨は、吸水性樹脂表面に、抗菌剤を揮発性溶
剤中に溶解もしくは分散させて得た溶液もしくは分散液
を付着させた後、揮発性溶剤を除去することにより吸水
性樹脂表面に抗菌剤被膜を設けたことを特徴とする抗菌
性樹脂組成物の製造方法である。(Means for Solving the Problems) The gist of the present invention is to apply a solution or dispersion obtained by dissolving or dispersing an antibacterial agent in a volatile solvent to the surface of a water-absorbing resin, and then applying the volatile solvent to the surface of the water-absorbing resin. This is a method for producing an antibacterial resin composition, characterized in that an antibacterial agent coating is provided on the surface of a water-absorbing resin by removing the antibacterial agent.
即ち、本発明は吸水性樹脂表面を抗菌剤の被膜で被覆し
て吸水性樹脂自体に抗菌性を付与するものである。That is, the present invention provides antibacterial properties to the water absorbent resin itself by coating the surface of the water absorbent resin with a film of an antibacterial agent.
本発明について更に詳しく説明する。The present invention will be explained in more detail.
先ず、本発明で用いる吸水性樹脂としては、従来よりお

ルコール・アクリル酸塩共重合体、アクリル酸塩・アク
リルアミド共重合体、セルロース・アクリル酸塩共重合
体などであり、特に、ポリアクリル酸ナトリウム塩が好
ましい。First, the water-absorbing resin used in the present invention is conventionally used in diapers, sanitary products, food drip sheets, dew prevention materials,
Any water-absorbing resin used in pet sheets, agricultural and horticultural materials, etc. may be used, such as crosslinked polyacrylates, starch-acrylate graft copolymers, vinyl alcohol-acrylate copolymers, etc. , acrylate/acrylamide copolymer, cellulose/acrylate copolymer, etc., and polyacrylic acid sodium salt is particularly preferred.
本発明で使用する抗菌剤としては、水溶液もしくは分散

成した場合、食品の味を変化させ、結露防止剤や園芸用
資材等の比較的長時間に亘って使用される吸水性シート
を形成した場合には抗菌剤が脱落して抗菌作用が長時間
持続できないからである。The antibacterial agent used in the present invention must form an aqueous solution or dispersion, but an antibacterial agent that is insoluble in water after forming a film on the surface of the water-absorbing resin is preferable. When a drip water-absorbent sheet for food is formed using an eluting antibacterial agent, it changes the taste of food and forms a water-absorbent sheet that can be used for a relatively long period of time as an anti-condensation agent or gardening material. If this happens, the antibacterial agent will fall off and the antibacterial effect will not last for a long time.

を使用する。The type and amount of the antibacterial agent used in the present invention vary depending on the use of the antibacterial water-absorbing resin. Depending on the application, ceramic coating materials containing metal ions and organic silicone quaternary ammonium salts are used for hygiene-related and food-related items that are directly related to the human body, and for agricultural and horticultural materials and cod prevention. Organic bromine compounds, benzimidazole compounds, organic arsenic compounds, etc. are used as agents.

.. 3 to 10 parts, preferably 1 to 5 parts, depending on the concentration of the active ingredient in the antimicrobial solution. If the amount of antibacterial agent is too small, mold and bacteria will grow easily, and if it is too large, there will be little effect on the amount used, and furthermore, depending on the type of antibacterial agent, gel strength tends to be extremely reduced.

表中の測定項目は次ぎの通りである。The measurement items in the table are as follows.

本添加量は吸水性樹脂100g当りの重量である。00 minute water absorption: 1 g of resin absorbs water for 10 minutes and drains for 5 minutes. Water absorption magnification is 280 times. Gel strength is 280 times. After leaving the gel after water absorption for 24 hours, a steel ball is placed in the center of the gel. Maximum diameter of the sphere (measured value 716 inches) Mold test = Investigation of mold growth when MS medium with 40x and 80x water absorption is left at 28℃ for 6 days + Active (no mold growth observed) - The amount added is the weight per 100g of water absorbent resin.
第2表の結果より、セラミックコーティング剤は結合力
が強いので添加量を増加しても吸水量及びゲル強度は低
下しないが、10.10’−オキシフェノキシアルカン
は結合力が弱いので抗菌剤が吸水他樹脂に付着している
だけであり、添加量増大に従い、吸水量、ゲル強度が低
下する。From the results in Table 2, it is clear that ceramic coating agents have a strong bonding force, so even if the amount added does not decrease the water absorption and gel strength, 10.10'-oxyphenoxyalkanes have a weak bonding force, so antibacterial agents do not decrease. It simply absorbs water and adheres to the resin, and as the amount added increases, the amount of water absorbed and the gel strength decrease.
