上記の範囲が好ましい。The present invention will be described in more detail below.
The method for producing the silica gel used in the present invention is not particularly limited, and it can be produced by a known method such as a vapor phase method or a wet method. The average particle size is preferably in the range of about 0.1 to 100 μm. Within this particle size range, the mixing efficiency with the synthetic resin becomes good, and the antibacterial and antifungal effect is evenly obtained on the surface of the synthetic resin. Even if the particle size of the antibacterial and antifungal material is smaller than this, there is no great difference in the antibacterial and antifungal effect obtained on the surface of the synthetic resin, and the antibacterial and antifungal material is likely to aggregate in the resin, resulting in poor dispersion. Further, when the particle size of the antibacterial / antifungal material is large, there are disadvantages such that the tensile strength of the mixed synthetic resin is partially reduced. Therefore, the particle size of the antibacterial and antifungal material is preferably within the above range.

The pore volume and the average pore diameter can also be selected in an appropriate range according to the application. Examples of the antibacterial and antifungal material include silver complex salts having antibacterial and antifungal properties, plant extracts, quaternary ammonium salts, and chlorhexazine gluconate.

シリカゲルを溶液から分離する方法が簡便である。The method for supporting the antibacterial and antifungal material on silica gel is not particularly limited, but silica gel is added to a solution containing the antibacterial and antifungal material as a solute and stirred to adsorb the antibacterial and antifungal material onto the silica gel. After that, the method of separating the silica gel from the solution by filtration or evaporation is convenient.

The range of about / 100 to 1/5 is preferable. Coating is 1 / diameter of silica gel particle
When it is 100 or less, the time-dependent release rate of the carried antibacterial and antifungal component is increased, the sustained release period, that is, the antibacterial and antifungal effect maintaining period is shortened, and the antibacterial and antifungal material is easily colored. When the coating film has a diameter of ⅕ or more of the silica gel particle diameter, the release of the antibacterial and antifungal component may be excessively limited.
