にまた、この消臭効果時間を長時間持続するものである
。(Effects of the Invention) The water-absorbing agent of the present invention thus obtained 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 excretions and liquids. , this deodorizing effect lasts for a long time.
従来の吸水性樹脂単独では、一部アンモニアを吸収する
ことは知られているが、吸水性樹脂とアパタイトとから
なる本発明の吸水剤は、従来用いられている吸水性樹脂
に比較してはるかに消臭効果が犬きく、シかも優れた吸
水能を保持するものである。It is known that conventional water-absorbing resins alone absorb some ammonia, but the water-absorbing agent of the present invention, which is composed of water-absorbing resin and apatite, is far more effective than conventional water-absorbing resins. It has a strong deodorizing effect and maintains excellent water absorption ability.
さらに驚くべきことには、吸水性樹脂とアパタイトとか
らなる本発明の吸水剤は水を吸収膨潤してゲルになった
時、そのゲル強度が吸水性樹脂単独の場合に比較して著
しく大きく、従来の吸水性樹脂のような止水層を形成せ
ず、水の分散性・移行性が著しく向上されたものである
。More surprisingly, when the water-absorbing agent of the present invention, which is composed of a water-absorbing resin and apatite, absorbs water and swells to form a gel, its gel strength is significantly greater than that of the water-absorbing resin alone. Unlike conventional water-absorbing resins, it does not form a water-blocking layer and has significantly improved water dispersibility and migration properties.
従って、おむつ等に用いた場合何度も吸収することがで
き、頗る有効である。Therefore, when used in diapers etc., it can be absorbed many times and is extremely effective.
また、多量の水を吸収した吸水性樹脂のゲルは長時間経
つとゲルに流動性が生じ、ゲル・フローという現象が認
められるが、本発明の吸水剤ではゲル・フローという現
象も紹められなくなる。In addition, the gel of a water-absorbing resin that has absorbed a large amount of water becomes fluid over a long period of time, and a phenomenon called gel flow is observed, but the water-absorbing agent of the present invention also introduces a phenomenon called gel flow. It disappears.
本発明の吸水剤は、大人用あるいは子供用の紙おむつ、
生理用品、靴中敷等の吸水・消臭に有効に使用すること
ができる。また、エアコン、空気清浄機、悪臭ガスの除
臭、ゴミ、し尿処理等の消臭、さらには悪臭汚泥の凝固
、乾燥剤等として広い用途に用いることかできる。The water absorbing agent of the present invention can be used for disposable diapers for adults or children,
It can be effectively used to absorb water and deodorize sanitary products, shoe insoles, etc. It can also be used in a wide range of applications, such as in air conditioners, air cleaners, deodorizing foul-smelling gas, deodorizing garbage and human waste treatment, coagulating foul-smelling sludge, and as a desiccant.
以下、実施例により本発明の詳細な説明するが、本発明
