Description of the Invention (1) Technical Field The present invention relates to antibacterial coatings and heating conditioners using the coatings for coating and processing. Technical background Coatings used in microwave ovens in the past can be classified as liquid coatings that retain the liquid shape by making thermoplastic resins or thermosetting resins such as acrylic resins, polyester resins, epoxy resins, and polyester denatured epoxy resins. , And powder coatings that retain the shape of the powder. Liquid paints include, for example, paints containing solvents, paints that are liquid at normal temperature, or emulsion paints in which resin components are dispersed in water. On the other hand, conventional microwave ovens use microwave heating conditioners, and furnace structure materials for foodstuffs use steel plates, galvanized steel plates, non-recorded steel plates or coated steel plates ^ Steel plates, key steel plates, and stainless steel plates to prevent rust In order to improve the corrosion resistance for processing such as non-adhesiveness, powder coating, heat-resistant coating, fluorine coating, and enamel are usually processed. When a microwave oven uses a microwave electric wave conditioning function to increase the electric heater with heating function, and when a microwave electric oven is formed, it is necessary to further perform heat-resistant coating with high heat resistance. However, the conventional liquid paint or powder paint is used for coating. The coated film does not have the antibacterial effect of inhibiting the proliferation of bacteria attached to the surface. In addition, the coating film after being coated with a liquid coating in which a liquid coating is mixed with an antibacterial agent such as silver, or a powder coating is generally mixed with an antibacterial agent such as silver. When the coating film is formed, the antibacterial agent is coated. It is buried in the coating film, so the antibacterial paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) Γ 4 ~ ---- r1 --- ΐ — I (Please read the precautions on the back before filling This page) Order-1-1 --........

Description of the invention (2 Standards for printing private paper printed by employees' consumer cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs apply Chinese national standards (CNS ) A4 size (210X297 mm) is displayed on the surface of the coating film. As a result, the effect of inhibiting the proliferation of bacteria on the surface of the coating film cannot be obtained. On the other hand, the interior of the microwave oven and microwave oven and the door wall surface are adhered to Escherichia coli, Staphylococcus aureus, etc. When food-attached bacteria are scattered, when the bacteria attached to human hands touch the microwave oven with hands, when the bacteria scattered by human sweat and saliva are attached, or when dust in the air is attached, These bacteria are attached to the microwave oven and Physical Possibilities》 Microwave ovens with electric heaters such as microwave ovens, when heated to a high temperature, the bacteria are eliminated, and then the bacteria are attached to the library due to radio wave conditioning and door openings. Therefore, 'food disease foam In microwave ovens with many other nutrient sources, the proliferation of attached bacteria on the wall surface of the furnace body and the door wall deteriorates hygiene. In particular, microwave ovens with a single function mainly based on radio wave conditioning are compared with microwave electric ovens using electric heaters. Because the temperature in the furnace is difficult to rise, it is very rare to use silicon-based and fluorine-based heat-resistant coatings, and powder coatings are cheap and relatively low heat-resistant coatings. Due to the difficulty of increasing the temperature in the furnace of a single-function microwave oven, there is still a problem that it is difficult to eliminate bacteria due to heat. 0 Disclosure of the Invention The antibacterial powder coating of the present invention contains a resin component for forming a coating film. , And the inorganic powder contained in it is responsible for the antibacterial agent of silver thiosulfate complex. 5-'(Please read the precautions on the back before filling this page)

Description of the invention (8) The obtained suspensions were filtered by bacteria with a pore size of 〇〇 丨 V m After treatment, the silver ion concentration in the filtrate was measured. As a result, the Ag concentration of the antibacterial agent A was 80 ppm, the Ag concentration of the antibacterial agent B was 3.5 PPm, the Ag concentration of the antibacterial agent C was 2.0 ppm, and the concentration of the antibacterial agent D2Ag was 0 to 01 ppm or less. From the above experimental results, it is fully shown that the silver compound contained in the antibacterial agent A is easily dissolved in polar substances such as water. In contrast, the silver or silver ions contained in the antibacterial agents B to D are not easily dissolved in ionic substances such as water. The dissolution characteristics of the silver ions affect its antibacterial performance. In other words, when the powdery coating material containing the antibacterial agent A is embedded in the coating film formed in the internal state, the silver compound or silver ion contained in the antibacterial agent A is contained in the water content and the like in the coating film. Dissolution, so that the eluted silver compound or silver ion easily causes bleeding on the surface of the coating film. Also, when the powder coating material containing the antibacterial agent A forms a coating film, the silver compound or silver ion contained in the antibacterial agent A dissolves in the polar compound and the like contained in the resin component, causing the eluted silver compound or silver ion to The appearance of bleeding is easily formed on the surface of the coating film. In addition, when the powder coating material containing the antibacterial agent A is heated and melted to form a coating film, a part of the antibacterial agent A easily forms a bleeding phenomenon on the surface of the coating film. For any of the reasons described above, it is speculated that the silver compound or silver ion in the antibacterial agent A is exposed on the surface of the coating film, and as a result, good antibacterial properties can be obtained.

Description of the invention (9) When the coating film is formed, it contains only antibacterial agents B to D that support silver or silver ion inorganic powder. The supported silver or silver ions are not easily dissolved in polar substances such as water, so it is difficult for silver or silver ions to ooze on the surface of the coating film. In addition, when the powder coating material containing the antibacterial agent B, C or D forms a coating film, the silver compound and silver ion contained in the antibacterial agent are not easily dissolved in the polar compounds and the like contained in the resin component, so that the dissolved Silver ions cannot ooze out on the surface of the coating film. In addition, when the coating film formed by powder coating containing the antibacterial agent B, C or D is heated and melted, the antibacterial agent B, C or D itself cannot bleed out on the surface of the coating film. Based on any of the above reasons, the antibacterial agent can be estimated The silver compounds or silver ions in B, C, or D did not form an exposed state on the surface of the coating film, so that the antibacterial result could not be obtained. In addition, other comparative examples using a liquid paint will be described below. Various liquid paints containing the above-mentioned antibacterial agents A to D and propyl resin and solvents were separately prepared, and then the various liquid paints were sprayed on a galvanized steel sheet to perform an electrostatic coating step. Next, after a heat treatment in a 210 ° C firing furnace for 15 minutes, a coating film was formed on the surface of the steel plate. After this treatment, test pieces of antibacterial products BB, CC, and DD were prepared. The surfaces of the above test pieces were inoculated with coliform and Staphylococcus aureus, and then each surface was wrapped with a thin film, and then left at 37 ° C for 24 hours.

The surface of the inorganic powder supporting the thiosulfate silver complex in the antibacterial agent may be further provided with a coating structure. Based on the control of the thickness of the coating layer, it is possible to adjust the dissolution amount of the silver thiosulfate complex in the antibacterial agent, and as a result, it is possible to adjust the antibacterial performance consistency. The thicker the coating layer, the slower the dissolution rate of the silver thiosulfate complex and the longer the duration of the antibacterial performance. The coating layer is not particularly limited, and inorganic substances such as silicon dioxide, magnesium oxide, titanium oxide, calcium carbonate, or organic substances such as silicone resin, epoxy resin, etc. may be used.

Invention Description (11) Performance. The resin composition of the antibacterial powder coating is not particularly limited. For example, thermoplastic resins and thermosetting resins such as acrylic resin, polyester resin, epoxy resin, and polyester modified epoxy resin can be used. The coating has a solid powder shape at normal temperature, and is heated to form a coating film. Β This antibacterial powder coating contains a resin component and an antibacterial agent. The antibacterial agent is dispersed in the resin component and mixed. It is most desirable that the resin component has a powdery structure. The antibacterial powder coating having this structure is shown in the aforementioned Figure 1 (A). In this structure, the average particle diameter of the inorganic powder supporting the thiosulfate silver complex with an antibacterial function is in the range of about 0.1 m to about 10 m, and the powder is mixed with the antibacterial agent to form a powder. The average particle diameter of the resin component in the shape is preferably in the range of about lym to about 30 / zm. With this structure, it is possible to obtain good antibacterial properties, and at the same time, it is possible to obtain the antibacterial powder coating in a simple process by simply mixing and dispersing the powder-shaped resin component and the powder-shaped antibacterial agent, so that the manufacturing cost can be reduced. Furthermore, the antibacterial powder coating material containing a resin component and an antibacterial agent may have a structure in which a powdery resin component and a powdery antibacterial agent are dispersed with each other.

The microwave oven door sills in Figures 4 and 5 include: front panel 10, a door sleeve of the blocking part for sealed radio wave shielding 丨 丨, which is equipped with a silver thiosulfate silver complex supported by silicon dioxide. The lintel structure member 12 after the antibacterial agent 1% powder powder coating is applied covers the hole film 13 provided in the lintel structure member 12. The lintel structure member 12 is coated on the surface of the metal base material 14 of the lintel structure member with an antibacterial 1 ° / 0 weight antibacterial agent containing silicon dioxide supporting a thiosulfate silver complex. The microwave oven lintel after the antibacterial coating is processed is made by the following process. First, a metal plate such as a galvanized steel sheet is subjected to a die-casting process, a bending process, a bite process, a welding process, or the like to form a door sill structural member 12. After that, the processed lintel structure part 12 is subjected to alkaline cleaning and degreasing, and ---- ^ ------- CT equipment -------- ΐτ -------- φ (please first (Please read the notes on the back and fill in this page.) A7 B7 printed by the Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs 5. The invention description (l5) is converted. Later in polyester modified epoxy resin powder coating _ combined with the antibacterial agent of thiosulfate silver complex supported by silicon dioxide (such as Si02 · nH2〇, Nax [Agm (S2〇3) y] z) l % By weight, the powder coating is electrostatically coated using a spray-blow door lintel structural member, and then heated in a 210eC firing furnace for 15 minutes to form a coating film. After this processing, an antibacterial agent is coated. Microwave oven door. A metal sheet with a coating film of 2 cm X 2 cm was cut out from the lintel structure member, and the antibacterial performance of the metal sheet was measured. As a result, the antibacterial performance has the same effect as the antibacterial product A described above. As described above, the microwave oven of the present invention is based on the structure described above, which can suppress the proliferation of bacteria attached to the lintel wall and reduce the number of bacteria growing on the lintel wall. As a result, a microwave oven with good cleanliness can be obtained. The possibility of industrial use is based on the antibacterial powder coating of the present invention as stated above. When the antibacterial powder coating is applied to form a coating film, even if the antibacterial agent is embedded in the coating film in the powder coating, the antibacterial effect is prevented. Agent contact with bacteria can also inhibit the proliferation of bacteria. Furthermore, the microwave oven using the antibacterial powder coating of the present invention can suppress the proliferation of bacteria attached to the inner wall surface of the furnace body and the lintel wall surface, reduce the number of bacteria that breed on the inner wall surface of the furnace body and the lintel wall surface, and as a result, it can be prepared with good cleaning.
