DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an aesthetic effect of lacquer ware by adding a mineral modifier to a natural lacquer paint or a synthetic resin paint for forming a coating layer on a fabric surface and kneading the mixture. The present invention also relates to a lacquer ware containing a mineral modifier in a coating layer capable of improving anti-bacterial or hygienic effects and improving health while at the same time improving the adhesion of paint.

2. Description of the Related Art Lacquer ware products are indispensable as Japanese-style aesthetic furnishings and Japanese-style dishes, but they are generally expensive and require considerable care in handling. There is. However, it can be said that the problem of high price has been almost solved today by the spread of fabrics made of synthetic resin materials that can be mass-produced and the development of synthetic resin paints. However, the problem of peeling of the coating layer generated from the basic structure that the lacquer ware is a coating material composed of a fabric and a coating layer is in a situation that cannot be easily improved.

[0003] That is, the coating layer in the lacquer ware, in luxury products, by the traditional natural lacquer paint,
In popular products, it is formed of a synthetic resin paint such as cashew. After these paints are applied to the dough, they are solidified by natural drying in a humidified atmosphere or by hot-air drying using a hot-air oven to form a coating layer on the surface of the dough. However, it is not possible to form a durable coating layer as in the case of baking metal. Therefore, the coating layer of lacquer ware products is easily damaged by the use of detergent containing abrasives, collision with other dishes, etc.
It is easy to peel off from the dough over time. This also makes the handling of lacquer ware products nervous.

[0004] Natural lacquer paints and synthetic resin paints are rarely used as a single composition, and iron oxide pigments are used for coloring, as well as modification of viscosity modifiers or extenders. It usually contains additives which should be called agents.
As such a modifying agent, there is a special one that a painter keeps confidential as a occupational secret of Ichiko-Senden. Is used.

[0005] Further, as a modifier, JP-A-2000-31
9587, JP-A-11-304231, JP-A-11-279445 and JP-A-10-270014
No. 6 discloses that a granule of tourmaline is added to a paint and used. According to these publications, the negative ions generated from tourmaline create a negative ionized atmosphere around the article coated with the paint. This atmosphere purifies the air in a manner similar to the natural environment.

Further, according to Japanese Patent Application Laid-Open No. 2000-264715, a "vessel" is used in which glaze contains tourmaline, and the glaze is applied to a magnetic or porcelain molded article and baked. It is described that the environment cleansing, sterilization, antibacterial action and texture are delicious.

[0007]

The above-mentioned modifiers composed of abrasive powder, clay, and soft rock powder can achieve the purpose of adjusting the viscosity and increasing the amount, but have the basic problems of lacquerware products. There is a problem that it does not contribute to the solution of the problem. In other words, prevention of peeling of the coating layer and improvement of the coating strength, improvement of aesthetic appearance when the lacquer ware product is an artistic furniture, antibacterial or hygienic effect or health promotion effect when the lacquer ware product is tableware Does not have any advantages. Conversely, heavy use as a bulking agent for the purpose of cost reduction involves the danger that the strength of the coating layer is rather reduced.

The present invention has been made in view of the above-mentioned problems in a conventionally used modifier such as abrasive powder, and has been developed as follows.
In addition to viscosity adjustment and volume increase effects, at the same time increase the peel resistance and coating strength of the coating layer, and at the same time, select a material that exhibits aesthetic effect, sanitary effect, and health promotion effect, so that the coating of lacquer ware products By improving the durability and peeling resistance of the layer, improving the handling and aesthetics of lacquerware products,
An object of the present invention is to provide a lacquer ware containing a mineral modifier in a coating layer newly imparted with effects of hygiene and health promotion.
Further, as described in Japanese Patent Application Laid-Open No. 2000-264715, a glaze or a ceramic material containing tourmaline powder is known, but the purpose thereof is mainly to improve health and the like. This is basically different from the object of the present invention, which is to solve the problems inherent in lacquer ware products such as enhancing the durability of the coating layer and the adhesion of the coating film.

[0009]

The present invention employs the following structure as means for achieving this object.

In the lacquer ware of the present invention containing a mineral modifier in the coating layer, a natural lacquer or synthetic resin coating layer is formed on the surface of a wooden or synthetic resin material. The lacquerware is characterized in that a natural lacquer paint or a synthetic resin paint for forming a coating layer is coated with a modifier mainly composed of tourmaline fine powder.

The fine powder of tourmaline in this configuration is
When added as a solid powder having high hardness to a natural lacquer paint or a synthetic resin paint which is a flowing viscous substance, the viscosity can be adjusted and the total amount can be increased. In addition, the kneaded tourmaline fine powder forms a coating layer on the surface of the fabric in a state of being dispersed in natural lacquer paint or synthetic resin paint, and increases the hardness of the coating layer by the magnitude of its hardness. In addition to being able to impart peeling durability, the coating layer has high brightness on the surface, has a hard glossy surface, and can impart antibacterial properties to the coating layer by its antibacterial action. Furthermore, the fine powder of tourmaline can negatively ionize the moisture in contact with the coating layer by the electric field, so that the taste of drinking water and food can be changed mildly, and the surface activity by the electric field can cause Food, edible oil and the like attached to the layer can be easily washed off.

The lacquer ware of the present invention containing a mineral modifier in the coating layer is applicable not only to natural lacquer paints and synthetic resin paints, but also to synthetic resin materials for forming fabrics. ,
A modifier mainly composed of tourmaline fine powder can be directly added to the material and kneaded.

Further, when fabric is made of a synthetic resin material, the crystalline resin (5% to 10% by weight) is contained in a glass containing tourmaline-containing ionic ceramic powder based on the total weight of the synthetic resin material. For example, PP
It can be used as a crystallization nucleating agent for a resin, a PET resin, a PBT resin material, or a composite resin formed by mixing these materials. In place of the ionic ceramic, 5 to 7% by weight of glass fiber or glass beads and 5 to 3% by weight of tourmaline powder may be added to the crystalline resin material.
The reason why the content of glass beads or glass fiber is set to 5 to 7% by weight is that when the content exceeds 7% by weight, a reinforcing agent (crystallization nucleating agent, here, glass) is exposed on the surface of the fabric, and when the content exceeds 10% by weight, the content is remarkable. In order to prevent the uniform finish of the coating film by being exposed to the surface, it is avoided.

In this configuration, the fine powder of tourmaline added at the time of molding exists in a dispersed state throughout the formed dough, and is compatible with the fine powder of tourmaline contained in the coating layer formed on the surface of the dough. In addition, the action specific to tourmaline can be synergistically exhibited. In addition, such lacquer ware can maintain the unique action of tourmaline by the tourmaline contained in the cloth even when the coating layer is peeled off. can do. and again,
Many polar groups (here, OH groups) are exposed on the surface of the molded dough, and the adhesion with the synthetic resin paint is further improved.
The aforementioned peeling, which is a drawback of the synthetic resin lacquer ware, is also eliminated.

[0015]

Embodiments of the present invention will be described below with reference to the drawings.

Among the lacquerware products, high-grade products manufactured by a traditional technique are provided with a base coat formed by applying an undercoat lacquer to a surface of a wooden fabric 11 formed into a predetermined shape by turning a wheel and drying and solidifying the lacquer. A film layer 12 and a finished coating layer 13 formed by applying a top coat lacquer on the surface and drying and solidifying the lacquer are formed (FIG. 1). The lacquer ware 10 illustrated in FIG. 1 is a soup bowl designed to be used as a matcha bowl or the like.

Undercoat lacquer is used for the purpose of impregnating a woody fabric to strengthen the fabric and to seal the fabric, and is conventionally used for 80% by weight of a natural lacquer paint. A powder obtained by adding 20% by weight of tourmaline fine powder TM in place of the abrasive powder and sufficiently kneading the mixture is used. The base coat layer 12 is formed by applying an undercoat lacquer kneaded with a fine powder of tourmaline TM to the entire cloth 11,
It can be formed by drying at room temperature in a humidified closed chamber. The fine powder of tourmaline TM is
The finest mesh class available is used, and the particles of the tourmaline fine powder TM in the underlying coating layer 12 can be observed under a microscope.

The top-coated lacquer is used for the purpose of coating the under-coated lacquer to adjust the texture of the surface and to form a thick coating layer with an overall thickness. At this time, as the overcoat lacquer, one obtained by adding 10% by weight of fine powder of tourmaline TM to 90% by weight of natural overcoat lacquer and sufficiently kneading is used. Further, the coating layer 13 in which the surface of the lacquer ware 10 is painted can be formed by applying a top-coat lacquer to the entire surface of the underlying coating layer 12 and drying it at room temperature in a humid environment. In the case of artistic lacquer ware products and the like, when a higher degree of finishing is required, an intermediate coating step is interposed between the undercoating step and the overcoating step, so that the base coating layer 12 and the finished coating layer 13 In between, any number of intermediate coating layers may be formed. In this case, it is preferable that the fine powder TM of tourmaline be omitted from the lacquer paint for the base and kneaded with the lacquer paint of the intermediate coating layer. The same effect can be expected while saving the amount of tourmaline used.

The lacquer ware 10 manufactured in this manner is made of the dough 1
Since the base coat layer 12 and the finish coat layer 13 each containing the fine powder of tourmaline TM are formed on the surface of No. 1 in an overlapping manner, the following characteristics are exhibited (FIG. 2). ). This will be described as a current usage of the lacquer ware 10, for example, a case where it is used as a matcha bowl.

First, the appearance of the lacquer ware 10 is higher in brightness and more intense than in those not containing tourmaline. This is considered to be because the particles of the fine powder of tourmaline TM are extremely fine, and the fine particles exhibit a translucent state when wet with the lacquer paint.

Further, in the lacquer ware 10, even if the matcha is stirred with a chasen, scratches due to the chasen in the lacquer ware 10 are hardly observed. This is considered to be because tourmaline is an extremely hard mineral, and its fine powder effectively reinforces the surface of the finished coating layer 13. In addition, the taste of matcha becomes soft. It is considered that this is because the water cluster is subdivided by the electric field of the fine powder of tourmaline TM and the water of matcha is ionized by the so-called negative ion effect of the fine powder of tourmaline TM. After use, the green pigment adhered to the lacquer ware 10 can be easily washed away only by washing with water. It is considered that this is because water is electrolyzed by the voltage of the fine powder of tourmaline TM to generate a surfactant. It should be noted that such an action of tourmaline can be qualitatively a generally determined action.

Next, an embodiment in which a resin material to which the fine powder of tourmaline TM is added is used for the cloth 11 and a synthetic resin paint to which the fine powder of tourmaline TM is added as the paint will be described (FIG. 3). Lacquer ware 10 illustrated in FIG. 1 is a serving dish for Japanese-style cooking.

The synthetic resin used for the cloth 11 can be selected from a crystalline resin such as PET resin, PP resin, PBT resin or the like, a composite resin obtained by mixing them, or a phenol resin material according to the application of the lacquer ware 10. . Then, the fine powder of tourmaline TM is added to the selected synthetic resin material and kneaded. At this time, as the particles of the fine powder of tourmaline TM contained in the dough 11, those having a larger diameter than those contained in the paint can be selected. That is, an injection molding machine is used for this molding, and the mixture is kneaded and melted simultaneously with the screw.

Ion ceramic (60% by weight of glass fiber, 40% by weight of fine powder of tourmaline) is added to the total weight of a crystalline resin material such as PET resin, PBT resin, PP resin or a composite resin material obtained by mixing them. And 10% by weight as a crystallization nucleating agent.
Instead of the ionic ceramic, 5 to 7% by weight of glass fiber or glass beads and 5 to 3% by weight of fine tourmaline powder MT may be added. 10% by weight of this ion ceramic or 5% of glass fiber or glass beads
The reason for setting to 7% by weight is that when the mixing ratio of glass fibers or glass beads exceeds 7% by weight, a reinforcing agent (here, glass fibers or glass beads) is exposed on the surface of the formed fabric, and 10% by weight is used. If the amount exceeds the above range, the film will be remarkably exposed, hindering a uniform finish of the coating film, and if the surface is not finished, it may be difficult to apply the coating. Furthermore, the reason why the fine powder MT of tourmaline is set to 5 to 3% by weight (40% by weight in the case of ionic ceramic) is that tourmaline has a large specific gravity, so that the weight increases as the blending ratio increases, and It is intended that the weight of synthetic resin lacquer ware often compared to lacquer ware be not heavier.

When a phenolic resin material is molded into a dough, the fine powder of tourmaline TM can be blended in a range of 10 to 40% by weight based on the total weight of the resin material. However, in such a case, it is better to use a large amount in the case of a flower vase, but when using it as a tableware or a lunch box, it is preferable that the mixing ratio be as low as possible for the above-described reason.

Further, it is possible to mix and form the conventionally used ABS resin and AS resin material with fine powder TM of tourmaline in the range of 10 to 40% by weight in the same manner as the phenol resin material as described above. However, the ABS resin or the AS resin is charged after molding and generates static electricity. Therefore, the use of a material that charges static electricity is not preferable because the ability to generate negative ions is reduced.

On the surface of the dough 11 molded by an injection molding machine (not shown), 15% by weight of a fine powder of tourmaline TM was added to 85% by weight of cashew paint and kneaded. Apply the synthetic resin paint obtained by
A finished coating layer 13 is formed (FIG. 4). The coating layer 13 can be efficiently formed by applying a synthetic resin paint to the cloth 11 that has undergone a predetermined process, and then forcibly drying it in a hot air oven. When a crystalline resin material is molded, the paint can be dried at 120 ° C. to 140 ° C., which is the crystallization temperature of the resin after coating, to promote the crystallization of the resin.

The lacquer ware 1 thus manufactured
0B can exhibit the same operational effects as the lacquer ware 10A according to the traditional manufacturing method in the above embodiment. However, since the lacquer ware 10B of this embodiment also contains the fine powder of tourmaline TM in the material thereof, the effect of the fine powder of tourmaline TM can be maintained even when the coating layer 13 is peeled off.

The lacquer ware 10A in the form of a soup bowl and the lacquer ware 10B in the form of a serving dish have been exemplified above. The technique of adding and kneading can be widely applied to other lacquer ware products, and different effects may be noticed depending on the type of lacquer ware product to be applied. For example, when applied to a vase, water is negatively ionized and becomes hard to rot, and the fresh flowers last longer.

Also, fine powder T of tourmaline, which is the main component,
There are various types of substances that can be added to M as sub-components, provided that they do not reduce the strength of the coating layers 12 and 13 and that they do not offset the effect of tourmaline. For example, mineral powder or the like conventionally used as a modifier may be used as an auxiliary component, and as an artificial material, a ceramic having high electrical insulation such as alumina or silica is used as an auxiliary component. , Can promote the effect of tourmaline.

[0031]

According to the present invention, a lacquer ware containing a mineral modifier in the coating layer is selected from a fine powder of tourmaline, which is a hard mineral, as a main component, and is used as a natural lacquer. Since it is added to a paint or synthetic resin paint and applied as a paint to form a coating film layer, the durability and peeling resistance of the coating film layer are greatly improved, and the specific action of tourmaline, specifically, The coating layer imparts a specific high-brightness gloss to the coating layer, and the glossy gloss is particularly suitable for an article in which emphasis is placed on the appearance of decoration such as a box, and the coating layer is hard, The tourmaline's electric field and emitted far-infrared rays have an antibacterial effect to prevent the propagation of various bacteria and a health-improving effect by negatively ionizing food and drinking water contained in lacquerware, and an effect of improving taste.

Furthermore, by adding tourmaline to the resin material, many polar groups are precipitated on the surface of the formed dough, thereby improving the adhesion to the synthetic resin paint, and the hardness of the coated film layer. In addition, it has the effect of solving the problem of coating peeling.
