DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to relates to antibacterial wax.

[0002]

2. Description of the Related Art Wax is used for the purpose of protecting and polishing the surface of building materials such as flooring materials, tiles and wood, and the surface of automobiles. However, on the surface to which the wax is applied, bacteria are propagated using the attached water droplets as a habitat, resulting in bad smell, darkening, slimming, and the like. Therefore,
Organic antibacterial agents such as phenol have been used in a mixture with wax.

[0003]

The organic antibacterial agent mixed with the wax has a problem that its safety to the human body and the environment is uneasy.

It is another object of the present invention to provide an antibacterial wax which is less likely to cause bacterial contamination and has high safety to the human body and the environment.

[0005]

The present invention according to claim 1 is an antibacterial wax in which an inorganic antibacterial agent is mixed with a paste wax, a liquid wax and an emulsified wax.

[0006]

According to the first aspect of the present invention, the inorganic antibacterial agent mixed with the wax suppresses the growth of microorganisms adhering to the wax, and is also an inorganic antibacterial agent. high.

[0007]

[Example] In the following, the present invention will be explain.

(Example 1 ) The inorganic antibacterial agent used in the antibacterial wax of the present embodiment is a silver silica gel antibacterial agent.

[0012] 12 parts by weight of carnauba wax, 5 parts by weight of bleached montan wax, 3 parts by weight of ceresin, 11 parts by weight of paraffin, 60 parts by weight of mineral spirit, 9 parts by weight of mineral terpen and 1 part by weight of a silver silica gel antibacterial agent are mixed and paste. To obtain antibacterial wax. This antibacterial wax was applied to the surface of wood plywood for floors and tested by the following method.

[0010] The antibacterial test was carried out using Escherichia col.
i ), Staphylococcus aureus was used, and the method was applied according to the method of dropping bacteria. Evaluation was performed 3 days later. The results are shown in (Table 1).

[0011]

[Table 1] This antibacterial wax is compared with a conventional organic antibacterial wax and a wax to which no antibacterial agent is added, and the results of a discoloration test by exposure to ultraviolet light and a discoloration test by immersion in a chlorine-based detergent are shown in Table 2. . In addition, for the UV exposure test, the change in the wax surface color after exposure to the sunshine weatherometer for 2000 hours was examined, and for the chlorine-based detergent immersion test, the change in the wax surface color after immersion in a 5% aqueous solution of sodium hypochlorite for 100 hours was examined.

[0012]

[Table 2] Further, the antibacterial wax and the antibacterial agent-free wax were applied to the surface of the floor plywood to which dirt had adhered, and the dirt removing ability was examined. The results are shown in (Table 3).

[0013]

[Table 3] Table 1 shows that the antibacterial wax of this example has practical antibacterial performance.

From Table 2, it can be seen that the antibacterial wax of this embodiment has practical discoloration resistance.

From Table 3, it can be seen that the antibacterial wax of this embodiment has practical stain removing performance.

Example 2 37 parts by weight of carnauba wax, 38 parts by weight of paraffin, 25 parts by weight of barium stearate, 800 parts by weight of mineral spirit, and 100 parts by weight of mineral terpene, the same silver silica gel antibacterial agent 1 as in Example 6 Parts by weight and 3 parts by weight of calcium stearate are mixed and sufficiently stirred to obtain an antibacterial wax.

This antibacterial wax was applied to the surface of linoleum for flooring, and an antibacterial test was conducted in the same manner as in Example 1 . The result is the same as that of Example 1, and it is understood that it has practical antibacterial performance.

The antibacterial wax was compared with a conventional antibacterial wax and a wax to which no antibacterial agent was added, and a discoloration test by exposure to ultraviolet rays and a discoloration test by immersion in a chlorine-based detergent were performed in the same manner as in Example 1. I went in. It can be seen that the result is similar to that of Example 1 and has practical discoloration resistance.

Further, with respect to the dirt removing ability,
The same result as in Example 1 was obtained.

Example 3 In Example 3 , a silver zeolite antibacterial agent was prepared in the same manner using zeolite instead of silica gel as a carrier, and used as an antibacterial agent.

132 parts by weight of carnauba wax, oleic acid 13
Parts, triethanolamine 22 parts, borax 10 parts, water 990 parts, ceramic ammonia 20% solution 2
2 parts by weight of the silver zeolite-based antibacterial agent and 3 parts by weight of calcium stearate are mixed with 00 parts by weight, and sufficiently stirred to obtain an antibacterial wax.

The antibacterial wax was applied to the surface of a ceramic tile and subjected to an antibacterial test in the same manner as in Example 1 . The result is the same as that of Example 1, and it is understood that it has practical antibacterial performance.

The antibacterial wax was compared with a conventional antibacterial wax and a wax to which no antibacterial agent was added, and a discoloration test by exposure to ultraviolet light and a discoloration test by immersion in a chlorine-based detergent were performed in the same manner as in Example 1. I went in. It can be seen that the result is similar to that of Example 1 and has practical discoloration resistance.

Further, with respect to the dirt removing ability,
The same result as in Example 1 was obtained.

In the above embodiment, a silver thiosulfato complex was used as the inorganic antibacterial agent. However, the present invention is not limited to this, and other silver antibacterial agents may be used. Alternatively, a copper-based or zinc-based antibacterial agent may be used.

In the above embodiment, a hydrolyzate of tetraethoxysilane was used as a coating material for silica gel. However, the present invention is not limited to this. For example, a hydrolyzate of another tetraalkoxysilane such as tetramethoxysilane may be used. Is also good. Alternatively, other coating materials may be used.

As described above, the antibacterial wax of the present invention comprises:
It has a structure in which silver, which has high antibacterial action that is highly safe for the human body and the environment, is supported on silica gel or the like as a thiosulfato silver complex salt, and an antibacterial agent that stably maintains the effect for a long time is dispersed in wax. . The antibacterial agent added to the wax exerts an antibacterial effect on bacteria that have come into contact with the surface, and for bacteria that existed on the substrate surface before wax application, by mixing into the wax by application, Has an antibacterial effect inside the wax.

The wax-coated surface is exposed to chlorine-based chemicals and ultraviolet rays because it is used in various detergents and places exposed to sunlight, but the antibacterial agent in the wax is a coating of a hydrolyzate of tetraalkoxysilane. As a result, the antimicrobial component is less likely to be directly affected by chlorine or ultraviolet light, and thus can have stable antimicrobial action and discoloration resistance.

Further, paste wax, liquid wax and emulsified wax to which an antibacterial agent has been added can be used as a carrier for adsorbing the above antibacterial material by using silica gel as a light transmissive material having a refractive index similar to that of wax. The use of such a powder makes it possible to maintain transparency.

The inorganic antibacterial agent mixed in the antibacterial wax is fine particles having a Mohs hardness of 4 to 5 μm and is applied to a metal surface, wood, resin, ceramic tile and the like. In this case, only surface dirt can be polished without damaging the base.

[0031]

As is apparent from the above description, the present invention has the advantage that the use of an inorganic antibacterial agent has high safety to the human body and the environment and can maintain the antibacterial effect. .

Further, since the inorganic antibacterial agent is mixed with the wax, there is an advantage that the dirt removing ability is high.
