Description
【０００１】
【従来の技術】
陶磁器加飾の主な方法として上絵具が用いられているが、現在使用されている上絵具の大部分に鉛ガラスが使用されている。この絵具は酸やアルカリ弱く、これらの溶液に浸けると絵具の鉛が溶け出すことがある。また、金や銀などの金属を使った絵具で加飾した陶磁器があるが、これが陶磁器に強固に付着していない場合があり、長時間使用しているとこれらの加飾が剥がれ落ちることがある。さらに陶磁器表面の釉薬（ガラス）の中には酸に弱い種類があり、表面が劣化してしまう場合がある。
【０００２】
【発明が解決しようとする課題】
本発明が解決すべき課題は、陶磁器上絵加飾で使用されている絵具の剥離防止、酸やアルカリ溶液による鉛含有絵具の溶出防止、釉薬の表面劣化防止を図ることにある。
【０００３】
【発明が解決するための手段】
本発明の表面改質した陶磁器は、表面が釉薬で覆われ、上絵具で加飾された陶磁器表面に、アルミナゾルを用いてアルミナ膜を形成させてなる表面改質した陶磁器であって、該アルミナ膜として元素周期表の１Ａ族、２Ａ族の軽金属元素の少なくとも１種類を５０重量％以下含有したものを用いたことを特徴とする。
【０００４】
【作用】
アルミナゾルは陶磁器表面を覆っているガラスとの濡れ性が良く、容易に均一で、かつ非常に薄い透明な膜を陶磁器表面に形成することができる。これを焼成し、強固で緻密なアルミナ薄膜を陶磁器表面に形成させる。
【０００５】
アルミナは酸やアルカリに強く、堅いため、この緻密な薄膜でコーティングされると上絵具が保護され、耐酸性が向上するとともに、絵具の剥離防止、金、銀等の金属絵具の変色防止ができる。
【０００６】
アルミナゾルに軽金属元素を添加した物でコーティングすることにより、上記と同様な効果、またはそれ以上の効果が得られる。
【０００７】
【実施例】
以下、本発明の実施例を示して説明する。
【００１２】
〔実施例１〕
アルミナゾル溶液（固形分４重量％）に軽金属元素であるカルシウムの酸化物（酸化カルシウム）を２重量％添加させた溶液を調整し、鉛含有上絵具で加飾している陶磁器製陶板（５０ｍｍ×５０ｍｍ×５ｍｍ）をこれに浸け、引き上げてコーティングした。これを室温で乾燥させた後に、５００℃で５分間焼成し、陶板表面に１μｍ以下の表面保護膜を形成した。これらを４％酢酸水溶液１００ｍｌ（ミリリットル）に２４時間浸け、この溶液を採取し原子吸光装置で鉛溶出量を測定した。その結果比較のためのコーティングしていない試料に対し、コーティングした試料は鉛溶出量が１／１００程度に抑えられた。
【００１３】
【発明の効果】
本発明によって、陶磁器上絵具の耐酸性、耐アルカリ性が向上し、絵具の剥離が抑えられた。[0001]
[Prior art]
Upper paint is used as the main method for decorating ceramics, but lead glass is used in most of the upper paints currently used. This paint is weak in acid and alkali, and when immersed in these solutions, the lead of the paint may dissolve. Also, there are ceramics decorated with paints using metals such as gold and silver, but this may not adhere firmly to the ceramics, and these decorations may come off if used for a long time. is there. Furthermore, some glazes (glass) on the ceramic surface are vulnerable to acid, and the surface may deteriorate.
[0002]
[Problems to be solved by the invention]
The problems to be solved by the present invention are to prevent peeling of the paint used in the decoration on ceramics, to prevent the elution of lead-containing paint by an acid or alkali solution, and to prevent the surface deterioration of the glaze.
[0003]
[Means for Solving the Invention]
The surface-modified ceramic of the present invention is a surface-modified ceramic made by forming an alumina film using alumina sol on the surface of the ceramic covered with glaze and decorated with an upper paint. A film containing at least one kind of light metal elements of Group 1A and Group 2A in the periodic table of elements of 50% by weight or less is used.
[0004]
[Action]
Alumina sol has good wettability with the glass covering the ceramic surface and can easily form a uniform and very thin transparent film on the ceramic surface. This is fired to form a strong and dense alumina thin film on the ceramic surface.
[0005]
Alumina is resistant to acids and alkalis and is hard, so when coated with this dense thin film, the upper paint is protected, the acid resistance is improved, and the paint can be prevented from peeling off and the metallic paint such as gold and silver can be prevented from being discolored. .
[0006]
By coating with a material obtained by adding a light metal element to alumina sol, the same effect as described above or an effect higher than that can be obtained.
[0007]
【Example】
Examples of the present invention will be described below.
[0012]
[Example 1]
A ceramic porcelain plate (50mm x 50mm x 4mm) prepared by adding 2% by weight of calcium oxide (calcium oxide), a light metal element, to an alumina sol solution (solid content 4% by weight) and decorating with lead-containing paint 50 mm × 5 mm) was dipped in this, and it was pulled up and coated. After drying this at room temperature, it was baked at 500 ° C. for 5 minutes to form a surface protective film of 1 μm or less on the surface of the ceramic plate. These were immersed in 100 ml (milliliter) of 4% aqueous acetic acid for 24 hours, and this solution was collected and the amount of lead elution was measured with an atomic absorption device. As a result, the lead elution amount of the coated sample was suppressed to about 1/100 compared to the uncoated sample for comparison.
[0013]
【The invention's effect】
According to the present invention, the acid resistance and alkali resistance of the ceramic upper paint are improved, and the peeling of the paint is suppressed.
