Description

  The present invention relates to a souvenir product using a phosphorescent material, and more particularly to a soot product that can enjoy the color and pattern of an original camellia in a bright place and enjoy a phosphorescent pattern by phosphorescent particles scattered in a dark place.

  Phosphorescent materials are used for watches, electronic devices, automobile parts, and the like as nocturnal displays or signs. Various proposals that make use of this function have also been made.

For example, Patent Document 1 proposes a smoke or resin bus unit that utilizes the function of a phosphorescent material as a phosphorescent ultraviolet radiator. That is, a bath unit is proposed in which phosphorescent particles mainly composed of titanium oxide particles having a photocatalytic function and strontium aluminate (SrAl ₂ O ₄ ) are fixed in a layered or mixed granular form on the surface of a bathtub or bathtub lid. Yes.

  By the way, cocoon products are highly evaluated as products with strength, beauty and corrosion resistance due to the metal of the fabric and the glassy material formed on the surface, and cocoon products are widely used in products such as tableware, bathtubs, chemical equipment, medical instruments, etc. It is used. Among such cocoon products, for example, by using phosphorescent materials for tub products such as bathtubs, vases, foreheads, figurines, etc., you can enjoy the color and pattern of the original cocoon in bright places and phosphorescence by phosphorescent materials in dark places. You can provide a product that you enjoy.

  However, there are few such soot products, and especially no soot product that can enjoy the phosphorescent pattern formed by the phosphorescent material itself. Conventional products that use phosphorescent materials are manufactured so that the display or sign portion shines as brightly and uniformly as possible so that the display or sign portion can be easily recognized in the dark. The phosphorescent pattern formed by the phosphorescent material itself Is not something to enjoy. Moreover, it is difficult to form a phosphorescent pattern formed by the phosphorescent material itself by a conventional method using the phosphorescent material.

  For example, since the bus unit proposed in Patent Document 1 uses a phosphorescent material, phosphorescence can be observed in a dark place, but originally intended for ultraviolet radiation by the phosphorescent material, phosphorescence formed by the phosphorescent material itself. I can't expect the pattern to be fun. The phosphorescent decorative product proposed in Patent Document 2 is also disclosed for application to a bag product, but it is intended to add phosphorescence to characters, patterns, etc. drawn on the upper surface of the substrate, and is formed by the phosphorescent material itself. We cannot expect that the phosphorescent pattern will be enjoyable. In addition, the bathtub proposed in Patent Document 3 aims to enjoy a fantastic atmosphere that the phosphorescent material emits in the dark in an acrylic resin bathtub, and similarly, a phosphorescent pattern formed by the phosphorescent material itself. I cannot expect it to be fun.

  The present invention allows the user to enjoy the color and pattern of the cocoon product itself in a bright place and enjoy the phosphorescent pattern formed by the phosphorescent material itself in the dark place, further enhancing the product value of the conventional cocoon product. And it aims at providing the manufacturing method which manufactures such a soot product.

  In the soot product according to the present invention, phosphorescent particles are scattered in the soot-fired layer formed between the lower soot layer and the transparent soot layer on the surface so as to form a scattered phosphorescent pattern.

  In the above invention, the average particle diameter of the scattered phosphorescent particles is preferably 100 to 300 μm.

  The method for producing the glaze product according to the present invention comprises a step of forming a lower glaze layer on the surface of the dough metal, and a glaze mixed powder containing 0.5 to 5% of a phosphorescent material by mass% on the upper surface of the lower glaze layer by a dry method And a step of forming a firewood fired layer and a step of forming a transparent firewood layer on the upper surface of the firewood fired layer.

  The soot product according to the present invention can enjoy the color and pattern of the original soot in a bright place, and can enjoy a phosphorescent pattern by phosphorescent particles scattered in a dark place.

  Hereinafter, an embodiment of a bag product according to the present invention will be described. In the soot product according to the present invention, phosphorescent particles are scattered in the soot-fired layer formed between the lower soot layer and the transparent soot layer on the surface so as to form a scattered phosphorescent pattern. That is, it is important for the present soot product to have phosphorescent particles scattered in the fired fired layer. This makes it possible to enjoy scattered phosphorescent patterns in dark places, and the phosphorescent particles do not interfere with the original colors and patterns of cocoons, so you can enjoy the original colors and patterns of candy products in bright places. .

  As the metal used as the base material for the cocoon products, steel plates for cocoons, cast iron, Al-plated steel plates, Al-Zn-plated steel plates, aluminum and the like can be used. The lower bran layer can be constituted by a method of applying and firing a known lower bran used for glazed products such as tableware, bathtubs, etc., with the dough made of steel sheet for casting, cast iron and the like.

  A soot-fired layer in which phosphorescent particles are scattered is formed on the upper surface of the formed lower soot layer. In order to form a soot-fired layer interspersed with phosphorescent particles, it is preferable to screen by a dry method. That is, after firing the lower glaze layer, it is pulled out from the firing furnace, and the mixed powder of phosphorescent material powder and glaze is screened on the upper surface of the lower glaze layer while maintaining the temperature at a predetermined temperature, and this is fired again Put in a furnace and fire at a predetermined temperature. Then, this sieving and firing are performed several times to form a fired fired layer.

  A known phosphorescent material can be used as the phosphorescent material. For example, a phosphorescent material mainly composed of strontium aluminate containing europium and / or dysprosium can be used.

  For the sifting, it is preferable to use a mixed powder in which the phosphorescent material powder is dispersed in the glaze, and it is preferable to use a glaze mixed powder containing 0.5 to 5% by mass% of the phosphorescent material. Thereby, as will be described below, it is possible to obtain a phosphorescent pattern that shines beautifully in a dotted pattern. Such a scattered phosphorescent pattern cannot be obtained by a conventional method. That is, it is difficult to obtain a paste obtained by mixing a phosphorescent powder with an organic binder or a coating agent on a resin or smoked product surface, followed by baking or baking.

  As for the size of the scattered phosphorescent particles forming the phosphorescent pattern, the average particle diameter is preferably 100 to 300 μm. When the average particle diameter is less than 100 μm, the brightness of phosphorescence is low and it becomes difficult to recognize the pattern. On the other hand, if the average particle diameter exceeds 300 μm, the phosphorescent particles tend to be agglomerated, making it difficult to form a dot-like pattern. In addition, a well-known thing can be used for the glaze which mixes phosphorescent material powder. For example, a glaze composed of cinnabar, borax, soda ash, milk white material, and coloring material can be used.

  The soot product according to the present invention is obtained by forming a transparent soot layer on the top surface of such a soot fired layer. The transparent soot layer can be formed using known materials and methods.

  Table 1 below is a table showing test results obtained by variously changing the mass% of the phosphorescent material powder in the glaze mixed powder and examining the observed phosphorescence pattern and color difference. As shown in Table 1, it can be seen that when the phosphorescent material powder is 0.5 to 5.0% by mass, a scattered phosphorescent pattern is observed. That is, it can be seen that the mass% of the phosphorescent material powder is preferably 0.5 to 5.0% in order to enjoy a scattered phosphorescent pattern. FIG. 1 shows an image obtained by reducing (4 bits) and sharpening the color photographed image of this sample. The numbers in the figure indicate the mass% of the phosphorescent material powder. When the size of the dotted pattern seen in the figure was measured based on the color photographed image, the average diameter was 100 to 300 μm.

  Moreover, according to Table 1, when the mass% of phosphorescent material powder is 0.5 to 2.0%, it is determined that there is no change in color difference. However, it can be seen that the color difference increases to 1.05 at 3.0% by mass and the color difference to 2.10 at 4.0% by mass. That is, when the phosphor material powder mass% is 0.5 to 3.0%, the color and pattern of the candy product itself can be enjoyed in a bright place, but preferably the phosphor material powder mass% is 0.5 to 2.0%. It turns out that is good.

In Table 1, the color difference indicates an E ^* _ab value specified in JIS K5600-4-6. Moreover, the sample for a test was created as follows. That is, first, spray the lower glaze with a spray gun on a cast iron plate with a thickness of 5-7mm and 100x100mm to form a 0.07-0.12mm coating film (wet glazing), which is about 50min at 50-100 ° C And dried at 900 to 1000 ° C. for 7 to 10 minutes.

  Next, the fired layer of the lower glaze layer is pulled out of the furnace. First, the glaze is screened using a 28-32 mesh sieve, and this is baked at 900-1000 ° C. for about 1 min. Formed. And the glaze mixed powder drawn out from the furnace again and produced in advance was sieved using a 28-32 mesh sieve, and this was fired at 900-1000 ° C. for about 1 min. This sieving and firing was repeated a total of 3 times to form a fired fired layer. Finally, a transparent glaze was applied onto the fired fired layer and fired at 900 to 1000 ° C. for about 1 minute to form a transparent fired layer to prepare a sample.

  In addition, the glaze mixed powder is a mixed powder consisting of glaze composed of cinnabar, borax, soda ash, milk white material, coloring material and a predetermined amount of phosphorescent material powder (G-300L phosphorescent pigment made by Nemoto Special Chemical Co., Ltd.) in a bag. It was made by shaking for about 1 min. Moreover, the glaze used for forming the base glaze layer was the same component as the glaze of the glaze mixed powder. The ground glaze layer is preferably located between the lower glaze layer and the glaze fired layer and strengthens the entire glaze.

  When the cross section of the sample was observed, the thickness of the lower glaze layer was 0.07 to 0.12 mm, the thickness of the base glaze layer was approximately 0.4 mm, the thickness of the glaze fired layer was approximately 0.4 mm, and the thickness of the transparent glaze layer Was about 0.2 mm.

  Heretofore, the soot product and the soot production method according to the present invention have been described. The present invention is not limited to the above embodiments. For example, the dough can be used for cloisonne products using copper, silver, gold or the like.

  Using a glaze powder containing 1% by mass of phosphorescent material powder (G-300L phosphorescent pigment manufactured by Nemoto Special Chemical Co., Ltd.) in mass%, a bath tub with a capacity of 330L was prepared in the same manner as the sample shown in Table 1 above. did. When this bathtub was observed in a bright place, the colors and patterns were vivid, and the colors and patterns were observed to be equivalent to those of ordinary bathtubs. Further, in the dark place, a clean spot-like phosphorescent pattern was observed for 30 to 60 minutes.

  Using the sample produced in the test of Table 1, a coaster was produced, and a cup with whiskey poured thereon was placed on it, and a test was conducted as to how it was observed in the dark. Through the cup, a beautiful scattered phosphorescent pattern was observed when the mass% of the phosphorescent material powder was in the range of 0.5-5.0%. Note that the phosphorescence pattern of 10.0% by mass% was not necessarily scattered, but clean phosphorescence was observed.

It is drawing which shows the image which reduced and sharpened the color photography image of the sample shown in Table 1. FIG.
