The invention of claim 1 is an antifungal composition comprising water glass as an inorganic antifungal agent and isopropyl alcohol (hereinafter abbreviated as IPA) type thiazolylsulfamide compound as an organic antifungal agent. Is prepared. As the water glass, it is possible to use Ag-containing glass, but it is preferable to use Ag-free water glass from the viewpoint of safety for the human body. Examples of the IPA-based thiazolyl sulfamide compound include 2- (4-thiazolyl) -1

Adding more than this is disadvantageous in terms of cost. Further, in this antifungal composition, the mixing ratio of water glass and the IPA-based thiazolylsulfamide compound is such that the addition amount of water glass to the caulking agent is in the range of 0.5 to 3.0% by weight. It is preferable to set the amount of the IPA-based thiazolyl sulfamide compound added to be in the range of 0.5 to 2.0% by weight. If the immediate effect is important, the blending ratio of water glass should be reduced, and if the effect persistence (redundancy) is emphasized, the blending ratio of water glass should be increased.

ある。A comparison between water glass and the IPA-based thiazolyl sulfamide compound shows that water glass is more easily eluted into water than the IPA-based thiazolyl sulfamide compound.
PA-based thiazolylsulfamide compounds are more difficult to elute than water, and when water glass is used alone, it elutes in a short period of time and the residual rate is low, and when IPA-based thiazolylsulfamide compounds are used alone, it is effective. It takes a long time to get out. On the other hand, in the fungicide composition comprising the above inorganic water glass and the organic IPA thiazolyl sulfamide compound, the water glass which is easily eluted and the IPA thiazolyl sulfamide which is difficult to be eluted Since the de-compounds will be eluted together on the surface of the caulking agent in a mixed state, the elution rate of water glass will be slowed down by the IPA-based thiazolylsulfamide compound, and the IPA-based thiazolylsul The elution speed of the famid compound is increased by being dragged by water glass, and as a result, the synergistic effect of the combination of water glass and the IPA-based thiazolylsulfamide compound results in caulking of the fungicide composition from the initial stage to the long term. The agent can be eluted on the surface of the agent and can stably exhibit the antifungal effect over a long period of time.

ことができる。The invention of claim 2 is characterized in that an antifungal composition is prepared by mixing water glass which is an inorganic antifungal agent and a quaternary ammonium salt which is an organic antifungal agent. To do. As the water glass, it is possible to use Ag-containing glass, but it is preferable to use Ag-free water glass from the viewpoint of safety for the human body. As the quaternary ammonium salt, benzalkonium chloride, benzethonium chloride or the like can be used.

ができるものである。Here, comparing the water glass and the quaternary ammonium salt, the quaternary ammonium salt is easier to elute in water than water glass, and the water glass is less likely to elute in water than the quaternary ammonium salt. . In the fungicide composition comprising such an inorganic water glass and an organic quaternary ammonium salt, the caulking agent is a mixture of the quaternary ammonium salt that is easily eluted and the water glass that is difficult to be eluted. The elution rate of the quaternary ammonium salt is slowed by the water glass because it is eluted on the surface of the water, and the elution rate of the water glass is increased by the quaternary ammonium salt. By the synergistic effect of the combination of water glass and quaternary ammonium salt, the fungicide composition can be eluted on the surface of the caulking agent from the beginning to the long term, and the fungicidal effect is stably exhibited for a long term. It can be done.
