[Figure 4] FIG. 4 is a flowchart for explaining a method of manufacturing an adhesive using the coating stock solution manufactured by the manufacturing method shown in FIG. 1.

Modes for Carrying Out the Invention

[0014] Hereinafter, embodiments of the present invention will be described. <First Embodiment> Hereinafter, a coating stock solution manufacturing method and a coating stock solution according to a first embodiment of the present invention will be described. FIG. 1 is a flowchart for explaining a coating stock solution manufacturing method according to a first embodiment of the present invention. Each step will be described.

[0015] Step ST1: Dilute the silica compound so that the volume of the silica compound is 1 and the volume of purified water or pure water is 0.7.

[0016] Step ST2: Note: There seems to be a formatting issue with the tag <第1実施形態> which was translated as <First Embodiment> but it might be better to keep it in its original form if possible. Also, there is a tag which is not translated in the original text but is just repeated. It's not clear if this is intentional or an error. If it's an error, it should be removed or corrected in the original text for proper translation.In step ST1, a surfactant is added to the diluted liquid so that the weight percentage is 0.5% to 2%. If the surfactant is less than 0.5% by weight, the possibility of aggregation increases. On the other hand, if the surfactant exceeds 2% by weight, the drying of the film will be delayed. As the surfactant, a non-ionic weakly alkaline one is used. As the non-ionic weakly alkaline surfactant, since Guardflex is strongly alkaline, a non-ionic type that is less affected by pH is suitable. Also, by using a weakly alkaline surfactant, it is possible to disperse uniformly while preventing aggregation. Examples of non-ionic weakly alkaline chemicals include polyoxyethylene-based, sorbitan-based, polyoxypropylene-polyoxyethylene copolymers, etc.

[0017] Step ST3: The liquid obtained in step ST2 is subjected to nanosizing treatment using a high-speed stirrer so that the particle size becomes 10 to 50 nm to produce a paint stock solution in which a nano film is formed. The particle size shall be 10 to 50 nm. In this way, by performing the nanosizing treatment, the surface of the substance is covered with nanoparticles (forming a nano film on the surface and inside of the refractory), and the durability is improved.

[0018] The paint stock solution of this embodiment is manufactured by the manufacturing method shown in FIG. 1.

[0019] <Second Embodiment> Hereinafter, a method for manufacturing a fireproof paint and a fireproof paint according to the second embodiment of the present invention will be described. FIG. 2 is a flowchart for explaining a method for manufacturing a fireproof paint according to the second embodiment of the present invention. Step ST21: A silane coupling agent is added to the paint stock solution manufactured in the first embodiment at a volume ratio of 1% to 3% to manufacture a fireproof paint.

[0020] By using a silane coupling agent, when the fireproof paint dries, a three-dimensional silica structure is formed on the film surface, and water can be repelled to improve water resistance.

[0021] The fire-retardant paint of this embodiment was manufactured by the manufacturing method shown in Figure 2.

[0022] The following describes the case where fire-retardant paint manufactured using the method shown in Figure 2 above is applied to metal parts. Figure 3 is a flowchart illustrating the process of applying fire-retardant paint, manufactured using the method shown in Figure 2, to a metal part. Step ST31: To improve adhesion, a silane coupling agent is applied to the metal part as a primer.

[0023] Step ST32: After step ST31, the fire-retardant paint obtained by adding a silane coupling agent in a volume ratio of 1-3% to the paint concentrate manufactured by the manufacturing method shown in Figure 1 is applied to the metal part.

[0024] In this way, applying it to the metal surface first creates a three-dimensional silica structure, which then intertwines with each other, increasing the degree of adhesion. If the volume ratio of the silane coupling agent is less than 1%, sufficient adhesion cannot be obtained. Furthermore, if the volume ratio exceeds 3%, the silica structure will not be formed correctly. If the only goal is to improve water resistance, in addition to a silane coupling agent (which offers good transparency), you can also add 10% silicon carbide (gray; this is also acceptable if it's a paint base coat). You may add CNF (cellulose nanofiber) at a volume ratio of approximately 5%. In other words, a silane coupling agent, silicon carbide, or CNF can also be used.

[0025] <Third Embodiment> The following describes a method for manufacturing an adhesive using the paint concentrate produced by the manufacturing method shown in Figure 1 above. Figure 4 is a flowchart illustrating a method for manufacturing adhesive using the paint concentrate produced by the manufacturing method shown in Figure 1. This flowchart specifically illustrates the process of applying the adhesive to a metal surface. Step ST41: To the paint stock solution prepared by the method shown in Figure 1, mineral viscous substances (such as kaolinite and montmorillonite) are added and stirred to produce an adhesive.

[0026] The amount of mineral viscous material to be added is determined based on the required lead time for drying.

[0027] <Other Embodiments> To produce a refractory coating, silicon carbide may be added to the paint concentrate of the first embodiment by volume %1 to 10, depending on the application, in order to efficiently generate radiant heat. Alternatively, a refractory coating may be manufactured by adding a material with a heat resistance of 2000 degrees Celsius or higher to the paint concentrate of the first embodiment in an amount of 1% to 3% by volume.

[0028] According to this embodiment, by spraying, coating, or immersing the wood material, the wood surface and By forming a nano-coating on the internal fibrous structure, it can exhibit fire-retardant properties. Furthermore, according to this embodiment, a nanofilm is formed on the surface by spraying or coating it onto a metal material, It can provide heat resistance and heat shielding effects. Furthermore, according to this embodiment, refractories used in industrial furnaces, etc. (refractory bricks, ceramic wool, etc.) By spraying, coating, or immersing, a nano-coating can be formed on the surface and inside of refractory materials, thereby improving their durability.

[0029] The present invention is not limited to the embodiments described above. In other words, those skilled in the art may make various modifications, combinations, subcombinations, and substitutions with respect to the components of the embodiments described above, within the technical scope of the present invention or its equivalents.

[0030] This invention can also be applied to chemical fibers. MSL (Guardflect: fire-resistant material) has extremely small colloids (500 nanometers to 10 nanometers), which allows it to form a coating on each individual nano-sized chemical fiber, making organic and inorganic materials non-combustible.

[0031] [Non-flammable inorganic blowing agent] While commercially available expanded polystyrene is widely used due to its light weight, it is susceptible to heat and lacks strength. For example, when MSL (Guardflect: a fire-resistant material) is heated, it produces something similar to white expanded polystyrene, but it does not burn even when heated with a burner or lighter, nor does it emit black smoke or harmful gases. By utilizing the foaming action characteristic of MSL, it is possible to manufacture non-combustible inorganic foam materials.

[0032] [Energy-saving effect due to heat reflection] Materials coated with MSL (iron, glass, etc.) reach their desired temperature faster than untreated materials due to the heat-shielding (reflective) effect of MSL. Furthermore, if SiC is added, radiation is added, further shortening the time to reach the desired temperature. [Industrial applicability]

[0033] This invention can be used in the fields of paint concentrates, methods for manufacturing the same, fire-retardant paints, methods for applying the same, adhesives, methods for manufacturing the same, paints for refractory materials, and methods for manufacturing the same.
