沖縄県に古くから伝わる琉球漆器は、デイゴ、シチャマギ（エゴノキ）など沖縄の木を乾燥させた後、これを削ったり、はり合わせたりして木地を作り、これに下地、中塗り、上塗りと何度も漆塗りを繰り返すことにより作られている。そして、漆を塗るたびに、ペーパーなどで表面を研ぎ、平滑とする。更に、この琉球漆器には、その装飾（加飾）として、沈金（ちんきん）、螺鈿（らでん）、箔絵（はくえ）、堆錦（ついきん）などが行われることが普通で、多彩な琉球漆器が得られている。 Ryukyu lacquerware, which has been handed down in Okinawa Prefecture since the beginning of the day, dried Okinawa trees such as Deigo, Shichamagi, etc., and then shaved or bonded them to create a bare wood, with a base, intermediate coat, and top coat. It is made by repeating lacquering many times. Each time lacquer is applied, the surface is sharpened with paper or the like to make it smooth. In addition, the Ryukyu lacquerware is usually decorated with decorations such as Chinkin, Raden, Hakue, and Nishiki. Na Ryukyu lacquerware has been obtained.
上記のようにして得られる琉球漆器は、外観が豪華であるため、広く一般のレストランや、家庭、病院あるいは養護施設等での使用が希望されるが、実際には次のような問題があり、使用は困難であるとされていた。 The Ryukyu lacquerware obtained as described above is gorgeous in appearance, so it is hoped that it will be widely used in general restaurants, homes, hospitals, nursing homes, etc. It was considered difficult to use.
すなわち、漆器の製造は、木地作り自体が数ヶ月を要する上に、何度もの漆塗りと乾燥、表面研ぎを行うため、製品が得られるまでに時間と手間がかかり、当然高価とならざるを得なかった。また、漆器は、衝撃や長時間の高熱に弱いため、例えば、最近使用されている自動洗浄機等での洗浄は難しく、その取り扱いにも注意が必要であるという問題があった。 In other words, the manufacture of lacquer ware requires several months to make the wood itself, and many times lacquering, drying, and surface sharpening, so it takes time and effort to obtain the product, and naturally it is not expensive. Did not get. In addition, since lacquerware is vulnerable to impacts and high heat for a long time, there is a problem that it is difficult to clean with, for example, a recently used automatic washing machine, and the handling thereof requires attention.
本発明は、上記実情においてなされたものであり、その課題は、漆器が有する上記の欠点を全て解消した漆器製品を製造するための素材を開発することである。 This invention is made | formed in the said situation, The subject is developing the raw material for manufacturing the lacquer ware product which eliminated all the said faults which a lacquer ware has.
本発明者らは、漆器と同様の外観を有しながら、これより水や熱に対する耐久性が高く、しかも簡単に製造することのできる製品を得るべく、鋭意検討を行った結果、漆を含浸させた繊維シートを基体とし、これを金属製金型を用いて所定の順序で成型して得た素材を使用することにより、上記目的が達成できることを見出し、本発明を完成した。 As a result of intensive investigations to obtain a product that has the same appearance as lacquer ware but has higher durability against water and heat and can be easily manufactured, the present inventors impregnated lacquer. It was found that the above object could be achieved by using the obtained fiber sheet as a substrate and using a material obtained by molding the fiber sheet in a predetermined order using a metal mold, and the present invention was completed.
すなわち本発明は、漆含浸繊維シートを、金属金型を用い、複数回の圧縮条件の異なる圧縮成型により成型することにより得られる漆器製品素材である。 That is, this invention is a lacquer ware product raw material obtained by shape | molding a lacquer impregnation fiber sheet by the compression molding from which a compression condition differs in multiple times using a metal metal mold | die.
また本発明は、漆含浸繊維シートを基体とし、これを金属製金型を用いて圧縮成型する漆器製品素材の製造法であって、圧縮成型が、複数回の圧縮条件の異なる圧縮成型工程により行われることを特徴とする漆器製品素材の製造法である。 Moreover, this invention is a manufacturing method of the lacquerware product raw material which uses a lacquer impregnation fiber sheet as a base | substrate, and compression-molds this using a metal mold | die, Comprising: Compression molding is carried out by the compression molding process from which multiple compression conditions differ. It is the manufacturing method of the lacquerware product material characterized by being performed.
本発明の漆器製品素材は、漆含浸繊維シートを圧縮成型することにより成型されるので、従来の漆器製品の素材と比べ、簡単な工程および短い時間で製造できるものであり、低コストで製造できるものである。 Since the lacquerware product material of the present invention is molded by compression molding a lacquer-impregnated fiber sheet, it can be manufactured in a simple process and in a short time compared to the material of a conventional lacquerware product, and can be manufactured at low cost. Is.
また、本発明の漆器製品素材を用いて得た漆器製品は、加熱処理を行った際に、ひずみ、変形など見られないことから、自動食器洗浄機や高温殺菌乾燥保管庫での取り扱いに耐えることができ、家庭での使用の他、耐久性の高い漆器製品として使用条件が過酷なレストラン、ホテル、福祉施設で高品質・高耐久かつ安価な食器、什器等として使用可能なものである。 In addition, lacquerware products obtained using the lacquerware product material of the present invention are resistant to handling in automatic dishwashers and high-temperature sterilization drying storages because they are not distorted or deformed when heat-treated. In addition to home use, it can be used as high-quality, highly durable and inexpensive tableware, furniture, etc. in restaurants, hotels, and welfare facilities where the use conditions are severe as rugged ware products with high durability.
本発明の漆器製品素材は、漆含浸繊維シートを基体とし、これを金属製金型を用いて複数回の異なる条件の圧縮成型工程で圧縮成型することにより製造される。 The lacquerware product material of the present invention is manufactured by using a lacquer-impregnated fiber sheet as a base and compression-molding it in a plurality of compression molding steps under different conditions using a metal mold.
基体である漆含浸繊維シートは、１枚ないし複数枚の繊維シートに、漆を含む成分を含浸させたものであり、その例としては、繊維シートの両面に生漆と糊料を混合したものを接着剤として塗布し、更にその上に、生漆、糊料および木粉等の繊維質の混合物を接着したものが挙げられる。 The lacquer-impregnated fiber sheet, which is the base, is a sheet in which one or a plurality of fiber sheets are impregnated with a component containing lacquer. For example, a mixture of raw lacquer and paste on both sides of the fiber sheet is used. The thing which apply | coated as adhesives and also adhere | attached fibrous mixtures, such as fresh lacquer, glue, and wood flour, on it is mentioned.
具体的に、接着剤として用いられる生漆と糊料を混合したものの例としては、生漆と糊（米粉：水分＝１：４）を等量で混合した糊漆に、小麦粉を２０質量％（以下、単に「％」で示す）程度加えた麦漆が挙げられ、生漆、糊料および木粉等の繊維質の混合物としては、上記麦漆に、木粉１０質量％程度、刻苧綿５質量％程度をそれぞれ加えた刻苧が挙げられる。 Specifically, as an example of a mixture of raw lacquer and glue used as an adhesive, paste lacquer mixed with equal amounts of raw lacquer and glue (rice flour: moisture = 1: 4), and 20% by weight of flour (hereinafter referred to as “waste flour”) , Simply indicated as “%”), and the mixture of fibers such as raw lacquer, paste, and wood flour is the above-mentioned wheat lacquer, about 10% by weight of wood flour, and 5% of chopped cotton An engraving with about% added.
また、繊維シートとしては、特に制約はないが、植物質の繊維布であることが好ましく、例えば、麻布、綿布（寒冷紗）等が使用される。更にこの繊維シートを構成する繊維布の枚数は、１枚でも良いが、漆成分を多く含有させるため、３ないし７枚程度とすることが好ましい。 Further, the fiber sheet is not particularly limited, but is preferably a vegetable fiber cloth. For example, linen cloth, cotton cloth (cold rice cake), or the like is used. Further, the number of the fiber cloths constituting the fiber sheet may be one, but is preferably about 3 to 7 in order to contain a lot of lacquer components.
更に別の漆含浸繊維シートとしては、糊漆、小麦粉（薄力粉）、木粉および刻苧綿（麻を細かく刻んだもの）を混合し、これを均一に固練りして作成した粘土状の刻苧材を離型剤(ラップ等)で包み込んだ後、ローラーで均一に延ばした漆含浸繊維シートを挙げることができる。 As another lacquer-impregnated fiber sheet, clay lacquer made by mixing paste lacquer, wheat flour (soft flour), wood flour and engraved cotton (finely chopped hemp) and kneading them uniformly. An example is a lacquer-impregnated fiber sheet in which a brazing material is wrapped with a release agent (such as wrap) and then uniformly spread with a roller.
次に、以上のように調製された漆含浸シートを成型し、漆器製品素材とするには、金属金型を用い、複数回の圧縮条件の異なる圧縮成型で成型することが必要である。すなわち、一段階で圧縮成型した場合には、漆含浸シート中の漆が固まらず、安定な成型品が得られないからである。 Next, in order to mold the lacquer impregnated sheet prepared as described above into a lacquer ware product material, it is necessary to use a metal mold and mold by compression molding with different compression conditions. That is, when compression molding is performed in one stage, the lacquer in the lacquer impregnated sheet does not harden and a stable molded product cannot be obtained.
この複数回の圧縮成型の例としては、加圧しないか、低い圧力で加圧して圧縮成型する工程と、高い圧力かつ常温ないし加温下で加圧して圧縮成型する工程を含む方法や、加圧しないか、低い圧力で加圧して圧縮成型する工程、高い圧力かつ常温で加圧して圧縮成型する工程および高い圧力かつ加温下で加圧して圧縮成型する工程を含む圧縮成型方法が挙げられる。 Examples of the multiple compression molding include a method including a step of compression molding by pressing at a low pressure or a pressurization at a low pressure, and a step of compression molding by pressing at a high pressure and at normal temperature or under heating. There are compression molding methods including a step of compression molding by pressing at a low pressure or at a low pressure, a step of compression molding by pressing at a high pressure and normal temperature, and a step of compression molding by pressing at a high pressure and warm temperature. .
後者の方法についての条件を例示すれば次の通りである。すなわち、加圧しないか、低い圧力で加圧して圧縮成型する工程（第１成型工程）は、１５ないし３５℃、好ましくは、室温程度の温度で、１ないし１０分、好ましくは、２ないし５分間、金型の自重のみないし１ないし５ｋｇ／ｃｍ２程度の圧力を金型にかけることにより行われる。この工程により、漆器の粗成型が行われる。 An example of conditions for the latter method is as follows. That is, the step of press-molding by pressing at a low pressure or at a low pressure (first molding step) is 15 to 35 ° C., preferably at a temperature of about room temperature, 1 to 10 minutes, preferably 2 to 5 It is performed by applying a pressure of only about 1 to 5 kg / cm 2 to the mold for a minute. By this process, rough molding of lacquer ware is performed.
また、高い圧力かつ常温で加圧して圧縮成型する工程（第２成型工程）は、１５ないし３５℃、好ましくは、室温程度の温度で、２０秒ないし３分、好ましくは３０秒ないし２分間程度、３０ないし７０ｋｇ／ｃｍ２程度、好ましくは、５０ｋｇ／ｃｍ２程度の圧力を金型にかけることにより行われる。この工程により、漆器の本成型が行われる。また、成型部外の漆含浸シート（縁部分）も切り取られる。 In addition, the compression molding step (second molding step) under high pressure and normal temperature (second molding step) is 15 to 35 ° C., preferably about room temperature, 20 seconds to 3 minutes, preferably about 30 seconds to 2 minutes. 30 to 70 kg / cm 2 , preferably about 50 kg / cm 2 is applied to the mold. Through this process, the main molding of the lacquer ware is performed. Moreover, the lacquer-impregnated sheet (edge part) outside the molded part is also cut off.
更に、高い圧力かつ加温下で加圧して圧縮成型する工程（第３成型工程）は、３５ないし８０℃、好ましくは、５０ないし７０℃程度の温度で、１ないし１０分、好ましくは、２ないし５分間程度、３０ないし１５０ｋｇ／ｃｍ２程度、好ましくは、５０ないし１００ｋｇ／ｃｍ２程度の圧力を金型にかけることにより行われる。この工程により、漆器の表面を滑面とすることができる。 Furthermore, the step of compression molding by pressing under high pressure and heating (third molding step) is performed at a temperature of 35 to 80 ° C., preferably about 50 to 70 ° C. for 1 to 10 minutes, preferably 2 It is carried out by applying a pressure of about 30 to 150 kg / cm 2 , preferably about 50 to 100 kg / cm 2 for about 5 minutes. By this step, the surface of the lacquer ware can be made smooth.
上記の金属金型中で漆含浸シートを成型するに当たっては、成型品を金型から外しやすくするために離型剤を用いることが好ましく、例えば、ラップフィルムを離型剤として用いることができる。 In molding the lacquer-impregnated sheet in the above metal mold, it is preferable to use a release agent in order to easily remove the molded product from the mold. For example, a wrap film can be used as the mold release agent.
なお、上記成型に当たっては、各圧縮成型工程間に乾燥工程を入れることが好ましく、この乾燥時間は、自然乾燥の場合１晩程度が好ましい。また、成型された漆含浸シート以外の部分は、第１成型工程で切断すると、乾燥していない漆が金型中に滲み出すことがあるので、第２成型工程以降に切断することが好ましい。 In addition, in the case of the said shaping | molding, it is preferable to put a drying process between each compression molding process, and this drying time is preferably about one night in the case of natural drying. Further, when the portion other than the molded lacquer impregnated sheet is cut in the first molding step, undried lacquer may ooze into the mold, and therefore, it is preferable to cut after the second molding step.
このようにして得られた、漆器製品素材は、素地固めのために、下地用生漆を１ないし数回塗布した後、乾燥させ、更に、色漆を上塗り塗布し乾燥させることにより、漆器製品とすることができる。下地用生漆および高耐久性漆の塗布や、これらの後に行う研ぎ工程も通常の漆器と同様に行えば良い。 The lacquerware product material obtained in this way is coated with raw lacquer for groundwork once or several times for solidification, and then dried and further coated with color lacquer and dried. can do. The application of raw lacquer for groundwork and highly durable lacquer, and the sharpening process performed after these may be performed in the same manner as for ordinary lacquerware.
また、必要により公知の漆器への加飾法、例えば、螺鈿、箔絵、沈金、堆錦等を施すこともできる。 Moreover, if necessary, a decorative method for a known lacquer ware, for example, a screwdriver, a foil picture, a goldsmith, a brocade or the like can be applied.
次に実施例を挙げ、本発明を更に詳しく説明するが、本発明はこれら実施例に何ら制約されるものではない。 EXAMPLES Next, although an Example is given and this invention is demonstrated in more detail, this invention is not restrict | limited at all by these Examples.

実 施 例 ３
琉球漆器様食器の製造：
第１段階：
実施例１で得た漆含浸繊維シートを、常温の金型（玉縁および高台を有する食器のデザインのもの）に、シワにならないように設置し、圧力をかけないで３分間の圧縮成型を行って成型品を金型から取り出し、離型剤（ラップ）を剥がし、１晩自然乾燥させた。漆含浸シートは十分な硬度に達するまでに時間がかかり、シートを切断すると漆が切断面から滲み出し金型内面に付着して成型性に問題が出るので、この段階では、成型された部分以外の漆含浸繊維シートは切断しなかった。なお、この段階での成型品は、変形しやすく不安定であった。
Example 3
Manufacture of Ryukyu lacquerware tableware:
First stage:
The lacquer-impregnated fiber sheet obtained in Example 1 was placed in a normal temperature mold (with a design of tableware with a rim and a plateau) so as not to be wrinkled, and subjected to compression molding for 3 minutes without applying pressure. The molded product was taken out from the mold, the release agent (wrap) was peeled off, and it was naturally dried overnight. The lacquer impregnated sheet takes time to reach a sufficient hardness, and when the sheet is cut, the lacquer oozes from the cut surface and adheres to the inner surface of the mold, causing problems with moldability. The lacquer-impregnated fiber sheet was not cut. The molded product at this stage was easily deformable and unstable.
第２段階：
乾燥した成型品を再度同一の金型を用いて成型圧力５０Ｋｇ／ｃｍ２で、１分間成型し、成型品を金型から取り出し、１晩乾燥させた。この段階で、成型された部分以外の漆含浸シートを切断した。なお、この段階で得た成型品は、完全に硬化していないので変形しやすい状態である。
Second stage:
The dried molded product was molded again with the same mold at a molding pressure of 50 kg / cm 2 for 1 minute, and the molded product was taken out of the mold and dried overnight. At this stage, the lacquer impregnated sheet other than the molded part was cut. In addition, since the molded product obtained at this stage is not completely cured, it is easily deformed.
第３段階：
２度圧縮成型した成型品の完全硬化と金型通りの型を得るために、金型温度（７０℃）に設定し、成型圧力（１００ｋｇ／ｃｍ２）で３分間の圧縮成型を行った。この結果、表面の平滑性に優れた漆器製品素材が得られた。このものは更に下地用生漆による素地固め、色漆による上塗りを行うことにより、漆器製品とすることができる。
Third stage:
In order to obtain complete curing of the molded product that was compression-molded twice and obtain a mold according to the mold, the mold temperature (70 ° C.) was set, and compression molding was performed for 3 minutes at a molding pressure (100 kg / cm 2 ). As a result, a lacquerware product material excellent in surface smoothness was obtained. This product can be made into a lacquerware product by further solidifying the substrate with raw lacquer for the foundation and applying it with colored lacquer.
実 施 例 ４
成型圧力および成型温度の検討：
平滑面を有する漆器製品素材を得るための第３段階での最適な圧力および温度を決めるため、以下のような実験を行った。
Example 4
Study of molding pressure and molding temperature:
In order to determine the optimum pressure and temperature in the third stage for obtaining a lacquerware product material having a smooth surface, the following experiment was conducted.
まず、実施例３の、第２段階で得た成型品について、５０℃の温度条件下、圧力を変えて第３段階の工程を行った。得られた漆器製品素材の成形性および離型性の良否を評価した。この結果を表１に示す。 First, the molded product obtained in the second stage of Example 3 was subjected to the third stage process by changing the pressure under the temperature condition of 50 ° C. The quality of moldability and releasability of the obtained lacquerware product materials was evaluated. The results are shown in Table 1.
また、同様に、５０ｋｇ／ｃｍ２の条件下、金型の温度を変えて、第３段階の工程を行った。得られた漆器製品素材の成形性および離型性の良否を評価した。この結果は表２に示す。 Similarly, the third stage process was performed by changing the temperature of the mold under the condition of 50 kg / cm 2 . The quality of moldability and releasability of the obtained lacquerware product material was evaluated. The results are shown in Table 2.
この結果から、第３段階での圧力は、５０〜１００ｋｇ／ｃｍ２、金型の温度は、５０〜７０℃が最適であると判断した。 From this result, it was judged that the optimum pressure in the third stage was 50 to 100 kg / cm 2 and the mold temperature was 50 to 70 ° C.
本発明の漆器製品素材は、漆と植物繊維からなる漆含浸繊維シートを圧縮成型することにより製造されたもので、総てが天然素材で製造されたものである。そして、本発明の漆器製品素材は、従来の漆器素材のように木ではないので、漆塗り後に加熱処理を施すこともでき（１００℃／３６０分）、それによって漆膜をより完全に硬化させることや、消費者の漆かぶれを解消させることあるいは乾燥を早め、納期を短縮することができる。 The lacquerware product material of the present invention is manufactured by compression-molding a lacquer-impregnated fiber sheet made of lacquer and plant fibers, and all are manufactured from natural materials. And since the lacquerware product material of the present invention is not wood like the conventional lacquerware material, it can be heat-treated after lacquering (100 ° C./360 minutes), thereby curing the lacquer film more completely. In addition, it is possible to eliminate lacquer rashes of consumers or to accelerate drying and shorten delivery time.
より具体的には、図１に示すように、木製高級漆器では、約２５工程（製作日数３５日程度）、木製普及漆器でも約１５工程（製作日数２０日程度）を要するのに対し、本発明の漆器製品素材を用いた漆器は、約６工程（製作日数６日程度）で製造可能である。 More specifically, as shown in FIG. 1, it takes about 25 steps (about 35 days of production) for a high-quality wooden lacquer ware, and about 15 steps (about 20 days of production) for a wooden popular lacquer ware. The lacquer ware using the lacquer ware product material of the invention can be manufactured in about 6 steps (about 6 days of production).
また本発明の漆器製品素材は、成型体を構成する主成分が漆であるため、仕上げの漆塗りの際の漆とのなじみが極めて良く、従来の漆器製作における繁雑な下地工程を省略することができる。このため、例えば、従来２４工程程度であった漆器製作工程数を６工程程度に大幅削減が可能であり、漆器製品製造のコストを大幅に低減することが可能である。 In addition, the main component of the lacquerware product material of the present invention is lacquer, so it is very familiar with lacquer when finishing lacquering, and the complicated groundwork process in conventional lacquerware production is omitted. Can do. For this reason, for example, the number of lacquer ware manufacturing processes, which was conventionally about 24 processes, can be greatly reduced to about 6 processes, and the cost of manufacturing lacquer ware products can be greatly reduced.
更に、漆含浸シートを作成し、これを金型で製造するものであるため、従来の木の素地と比べ、デザイン上の自由度が高くなり、新しい形状や、複雑な形状の漆器製品の製造が可能となる。 Furthermore, since a lacquer-impregnated sheet is created and manufactured using a mold, the design freedom is higher than that of conventional wood bases, and lacquerware products with new and complex shapes are manufactured. Is possible.
一方、本発明の漆器製品素材は、加熱処理を行った際にひずみ、変形などが生じないため、これを用いて作製された漆製品も、自動食器洗浄機や高温殺菌乾燥保管庫での取り扱いに耐える耐久性の高い漆器であり、使用条件が過酷なレストラン、ホテル、福祉施設においても使用可能な、高品質・高耐久かつ安価な食器、什器等の漆器製品とすることができるものである。 On the other hand, since the lacquerware product material of the present invention is not distorted or deformed when heat-treated, lacquer products made using this material can also be handled in automatic dishwashers and high-temperature sterilization drying storages. It is a highly durable lacquer ware that can withstand rust, and can be used in restaurants, hotels, welfare facilities with harsh use conditions, and can be used as lacquer ware products such as high-quality, highly durable and inexpensive tableware and furniture. .
