This article relates to antibacterial activated carbon used in deodorizers that remove bad odor components from rooms, cars, refrigerators, etc.

る。(Prior Art) An example of antibacterial activated carbon is disclosed in JP-A-1-278408. It is a mixture of activated carbon and zeolite that retains sterilizing metal ions such as silver and copper. In addition, there are also activated carbons in which a metal having a bactericidal property (hereinafter referred to as a bactericidal metal) such as silver or copper is attached to the surface of the activated carbon.

あった。(Problem to be solved by the invention) Impregnating a bactericidal metal on the surface of activated carbon has the disadvantage that it is difficult to obtain uniformity of impregnation and that ion elution varies, resulting in large variations in bactericidal performance and lifespan. was there.

相や気相等で使用した場合、活性炭と、殺菌性金属を保
持したゼオライトとが層分離してしまうことになる。In this respect, the method disclosed in the above publication can be said to be advantageous because the zeolite retains the bactericidal metal independently of the activated carbon. However, this is a macroscopic evaluation of the entire homogeneous mixture of activated carbon and zeolite that retains bactericidal metals, and microscopically, the functions still vary. For example, if the mixture is used in a liquid phase or gas phase where convection is possible, the activated carbon and the zeolite holding the bactericidal metal will separate into layers.
（課題を解決するための手段）
本発明は、殺菌性を有する金属を固着させた粒子状の芯
物質の外表面に活性炭を固着させた防菌性活性炭を要旨
とする。(Means for Solving the Problems) The gist of the present invention is antibacterial activated carbon in which activated carbon is fixed to the outer surface of a particulate core material to which a metal having bactericidal properties is fixed.
以下、詳述する。The details will be explained below.
まず、粒子状の芯物質としては、殺菌性金属を固着でき

きさにしておくと、固着性の点で好ましい。また、一般
に、２００μｍ以上の大きさにすると流動性の向上や、
容器等に充填して使用する際の圧力損失の低下を図るこ
とが容易になる。First, as the particulate core material, any material can be used as long as it can fix the sterilizing metal, but synthetic resins such as polyethylene and nylon, which have relatively soft surface hardness, are preferred. Although the size may be appropriately selected depending on the intended use, it is preferable to make the size five times or more larger than that of the sterilizing metal or activated carbon, from the viewpoint of adhesion. In general, if the size is 200 μm or more, fluidity will be improved,
It becomes easy to reduce pressure loss when filling a container or the like for use.
また、殺菌性を有する金属としては、銀や銅が一例とし
て挙げられる。大きさは適宜である。Further, examples of metals having bactericidal properties include silver and copper. The size is appropriate.

しい尚、製造過程で粉砕され、小さくなる場合もある。Furthermore, activated carbon can be used as appropriate regardless of raw materials, manufacturing methods, etc. The size is also appropriate, but it is preferable to make the size at least 5 times the size of the sterilizing metal because it will cover the sterilizing metal and stick to the particulate core substance. and may become smaller.

選択すればよい。By fixing a sterilizing metal to the particulate core material,
Furthermore, as a method for fixing activated carbon, there are methods using a ball mill, sand mill, mixer, roll mill, kneader, etc., or using a hybridization system as a mechanochemical method that has been attracting attention in recent years. Examples include encapsulation methods. You can select it as appropriate.
このとき、なるべく殺菌性金属を活性炭で覆うようにす
ると好ましい。殺菌性金属が外界に露出しない為、殺菌
性金属の脱落防止が図れるし、殺菌性金属がイオン化し
て溶出する際も、外表面に固着させた活性炭の間隙を通

防菌性活性炭を、改めて粒子状の芯物質の外表面に固着

用材料としてシリカゲルやゼオライト等の他の吸着材も
併用できなくはない。At this time, it is preferable to cover the sterilizing metal with activated carbon. Since the bactericidal metal is not exposed to the outside world, it is possible to prevent the bactericidal metal from falling off, and even when the bactericidal metal ionizes and elutes, it gradually elutes through the gaps in the activated carbon fixed to the outer surface. This is because the durability of the antibacterial effect is also increased. In addition, the antibacterial activated carbon obtained by the above treatment can be fixed again to the outer surface of the particulate core material to form an antibacterial activated carbon with a large particle size as a whole, or it is possible to make antibacterial activated carbon with a large particle size as a whole. After fixing the fixed particulate core material to the outer surface of the particulate core material, activated carbon is fixed to the outer surface of the particulate core material to obtain antibacterial activated carbon having a large particle size as a whole. etc. can also be done. Furthermore, other adsorbents such as silica gel and zeolite can also be used in combination.
