Description of the Related Art Conventionally, an inorganic coating composition using an aqueous solution of alkali silicate as a binder has almost no fine cracks in a vitreous coating film when an object to be applied is distorted due to thermal effects. There is a problem that the stains do not come off due to the infiltration of the sauce or the like, or the quality becomes poor due to the dripping of the chemical. Therefore, it is not suitable for use in a part affected by heat or as an interior / exterior material.

B 2 O 3 , 16H 2 O)
This is because a strong coating film is formed by vitrification of the B 2 O 3 component contained in colemanite or urexite. In addition, colemanite or urexite may be mixed with other natural glass, but the amount of colemanite or urexite is at least about 10% by weight of the total amount of the inorganic filler.
And the optimum is at least 30% by weight.

とするためである。The amount of the inorganic filler containing colemanite or urexite varies depending on the material to be coated such as a non-asbestos plate, a cement product, an asbestos slate plate and the like. The coating material having a large ratio can be blended in a small amount, and the blending can be adjusted in a wide range of 5 to 200 parts by weight with respect to 100 parts by weight of the alkali metal silicate as a binder. The reason why the natural glass was formed into a flake shape having an average particle diameter of 30 μm and a thickness of 1.0 μm or less is to form a coating film which can be mixed well and has a high covering power.

If the amount is less than this, the antibacterial effect is weak, and if the amount is more than 5 parts by weight, the antibacterial effect does not change so much, adversely affects the color development of the pigment, does not result in clear color development, and increases the cost. In particular, when the amount of silver powder and copper powder exceeds 4 parts by weight, the coating film becomes strongly yellowish and does not have a predetermined color.

5 to 40 parts by weight. If the amount is less than 7 parts by weight, the heat resistance effect is poor. If the amount is more than 60 parts by weight, the viscosity becomes high and the properties of the paint become poor.

Table 1 shows the results of the crack inspection, heat resistance performance and antibacterial performance of this coating film together with other examples 1-2 to 7. In addition, the crack inspection inspected the presence or absence of the crack of the coating film 8 hours after a boiling resistance test. The heat resistance was measured by continuously heating in an electric furnace atmosphere for 10 hours, and measuring the state temperature without any change in appearance. Furthermore, the antibacterial performance was measured by adding a suspension of Escherichia coli and Staphylococcus aureus to the sample at 1 m / m and culturing at 37 ° C for 24 hours. It was measured by a plate dilution method using a medium. According to this, there was a case in which heat resistance was excellent and Escherichia coli and Staphylococcus aureus remained in very small amounts, but the amount was further reduced after 24 hours or more, and a result in which antibacterial performance was excellent was obtained.

って塗料の性状が不良になったのである。Next, Table 8 shows Examples 6-1 to 7 in which the mixing amount of silicon carbide and antibacterial metal powder was increased or decreased from the above-mentioned example. Examples 6-1 and 6-2 are based on Examples 1-1 and 1-2, and are applied to a galvanized steel sheet. Embodiments 6-3 and 6-4 are based on Embodiments 2-2 and 2-6 and painted on an aluminum plate. Example 6
Nos. 5 and 6-6 are based on Examples 3-3 and 3-5 and are applied to a slate plate. Example 6-7 is based on Example 4-3 and applied to a sheet glass. In any case, the addition amount of the antibacterial metal powder can be used in the range of 0.4 to 5 parts by weight based on 100 parts by weight of the alkali metal silicate. When the amount was large, the antibacterial effect was good, but clear color formation was not obtained. The addition amount of silicon carbide is to provide heat resistance. If the amount is less than 7 parts by weight with respect to 100 parts by weight of the alkali metal silicate, the heat resistance temperature is not higher than 350 ° C. As a result, the viscosity of the paint deteriorated.

成できるのである。According to the first aspect of the present invention, since natural glass containing colemanite or urexite as an inorganic filler is in the form of fine scales, the covering power is improved by vitrification of the B 2 O 3 component. Adhesion with the object to be coated is promoted to form a strong coating, and since there is no crack, a coating having good chemical resistance and contamination resistance can be obtained, and the coating has a further antibacterial effect. It is excellent for use in the surface coating of interior materials that can be sterilized especially in hospitals and factories, and can form a deep, metallic, high-quality decorative panel.

効果があることから塗料の節約もでき安価となる。According to the second aspect, a good coating film can be obtained in a wide range irrespective of various objects to be coated. In the third aspect, since the covering power is further increased, a sufficient coating effect can be obtained even with a thin film of 20 μm or less. As a result, the paint can be saved and the cost can be reduced. According to the fourth aspect, since there is no crack, a coating film having good chemical resistance and stain resistance can be obtained, and the coating film having excellent antibacterial action and excellent heat resistance has a large effect. It is excellent for use in the surface coating of interior materials that can be sterilized, and can form high-quality decorative boards with a deep metallic tone. According to the fifth aspect, a good coating film can be obtained in a wide range irrespective of various kinds of objects to be coated. In the sixth aspect, since the coating power is further increased, even a thin film of 20 μm or less has a sufficient coating effect. The paint can be saved and the price is low.
