In the painting method according to the present invention, the object to be painted may contain bamboo material on its surface. [Effects of the Invention]

[0008] According to the present invention, the safety under the Food Sanitation Act is high, and various colors can be selected. Paint This invention provides a method for manufacturing a material and a painting method that allows for drying in a short time. [Modes for carrying out the invention]

[0009] Embodiments of the present invention will be described below. The paint composition according to the embodiment of the present invention comprises a non-toxic pigment, a vegetable oil, and a fatty acid. The paint composition according to the embodiment of the present invention may consist only of a non-toxic pigment, a vegetable oil, and a fatty acid. The object to be painted in the embodiment of the present invention is painted with a paint containing a non-toxic pigment, vegetable oil, and fatty acid. In the method for manufacturing paint according to an embodiment of the present invention, a non-toxic pigment, a vegetable oil, and a fatty acid are stirred and mixed while nanobubbles are generated inside.

[0010] Non-toxic pigments include, for example, mineral pigments that do not contain harmful substances such as cadmium, cobalt, and arsenic, as well as inorganic substances such as calcium oxide, and organic pigments such as plant-derived silica, plant-derived indigo, and carmine derived from cochineal insects, which are mainly composed of silicon dioxide. Vegetable oils include, for example, edible vegetable oils such as linseed oil, sunflower oil, sesame oil, rice bran oil, olive oil, coconut oil, and cottonseed oil. Fatty acids include, for example, saturated fatty acids such as palmitic acid and stearic acid, and unsaturated fatty acids such as oleic acid, linoleic acid, and linolenic acid. Because non-toxic pigments, vegetable oils, and fatty acids are used as paint raw materials, the manufactured paints have high safety standards under the Food Sanitation Act and a wide variety of colors are available.

[0011] The mass ratio of fatty acids to vegetable oil is preferably 0.5 to 3. The mass ratio of non-toxic pigments to vegetable oil is preferably 0.001 to 1, and particularly preferably 0.3 to 0.5, but this may vary depending on the object to be coated. In the coating method according to an embodiment of the present invention, a coating made by stirring and mixing a non-toxic pigment, vegetable oil, and fatty acid is applied to an object, and then the object is dried with hot air at 80-100°C. By drying with hot air at 80-100°C, drying can be achieved in a short time of several tens of seconds. In the coating method according to the embodiment of the present invention, it is preferable to apply a coating made by stirring and mixing a non-toxic pigment, vegetable oil, and fatty acid while generating nanobubbles inside the mixture to an object, and then dry the object with hot air at 80 to 100°C.

[0012] Nanobubbles can be generated by applying air pressure and blowing air using a commercially available nanobubble generator. Painting methods include, for example, spraying using a gun spray device, brush painting, and immersion. The objects to be painted include chopsticks, soup bowls, cutlery, trays, bowls, cups, bento boxes, donburi bowls, plates and other tableware, as well as dining tables, chairs, low tables, counters, cupboards, wagons, overhead cabinets, kitchen cabinet storage, coasters, plates, bottle openers, sieves, bamboo mats and other mats, ladles, tongs, sushi molds, sushi stands, wooden clogs and lids, sashimi serving boats, sushi tubs and rice containers, masu cups, combs, brushes, toothbrushes and other daily necessities, toys such as building blocks, baby toys and play kitchen toys, scratching posts, wooden playpens and kennels, pet furniture, pet dishes, pet brushes, wooden dumbbells and other pet toys and supplies, and anything else. Examples of materials for the objects to be painted include plastic, wood, and bamboo. Hot air drying can be performed using a commercially available hot air dryer.

[0013] In the painting method according to the embodiment of the present invention, it is preferable to paint the object with silica oil after drying with hot air. Commercially available plant-based silica oil can be used as the silica oil. Examples of painting methods include spraying using a gun spray device, brush application, and immersion. When silica oil is painted on the object after drying, the difference in particle size between the paint particles, which have been reduced in size by nanobubbles, and the larger particles of the silica oil makes it easier for the silica oil to adhere to the painted surface of the object after drying. After painting with silica oil, it is preferable to dry it with air. Silica oil can be dried in a short time of several tens of seconds by air drying.

[0014] In the painting method according to the present invention, the object to be painted may contain bamboo material on its surface. When painting bamboo, the oil content of the bamboo usually causes the paint to repel, making application difficult and leading to peeling. However, when the paint is made by stirring and mixing non-toxic pigments, vegetable oil, and fatty acids while generating nanobubbles internally, the paint particles become small and the liquid becomes smooth, making it less likely to cause uneven application and allowing for easy painting of bamboo that is less prone to peeling. According to the paint composition and the painted object of the embodiment of the present invention, it has high safety under the Food Hygiene Law and various colors can be selected. According to the method for producing a paint of the embodiment of the present invention, the produced paint has high safety under the Food Hygiene Law, various colors can be selected, and the produced paint can be uniformly applied to an object. Further, according to the painting method of the embodiment of the present invention, it can be dried in a short time after painting and is suitable for mass production.

Example

[0015] A paint was produced and painted according to the following formulation. A paint raw material composed of 10 parts by mass of calcium oxide, 500 parts by mass of sunflower oil or linseed oil, and 500 parts by mass of palmitic acid was put into a container and stirred and mixed for 10 minutes. After the well-mixed paint was applied to a bamboo chopstick by brush painting, the painted chopstick was dried with hot air at 90°C for 30 seconds by a hot air dryer. Thus, the completed painted bamboo chopstick had high safety under the Food Hygiene Law and could be dried in a short time by hot air drying.

Example

[0016] A paint was produced and painted according to the following formulation. A paint raw material composed of 10 parts by mass of calcium oxide, 500 parts by mass of sunflower oil, and 500 parts by mass of palmitic acid was put into a container and stirred and mixed for 10 minutes while generating nanobubbles inside the paint raw material by a nanobubble generator. After the well-mixed paint was applied to a bamboo chopstick by brush painting, the painted chopstick was dried with hot air at 90°C for 30 seconds by a hot air dryer. After drying, silica oil was applied once to the chopstick by brush painting. After painting, it was dried by a blower for 30 seconds. Thus, the completed painted bamboo chopstick had high safety under the Food Hygiene Law, was uniformly and evenly painted, and could be dried in a short time by hot air drying after painting the paint and air drying after applying the silica oil. The painted state of the finished product had strong adhesion to the chopstick, was difficult to peel off, and was a firm paint.
