本発明は、タイル、道路舗装用敷物等の窯業製品の滑り
止めの凹凸を形成するための処理法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a treatment method for forming anti-slip irregularities on ceramic products such as tiles and road paving mats.
従来、かかる窯業製品の表面に滑り止とを形成する処理
方法として、生素地の段階でプレスによって表面に凹凸
を形成する方法、特開昭６０−２０８５５４号公報に記
載されているように、釉薬中に釉焼温度よりも高い融点
を有する微細粒子を混入して釉焼時に凹凸を形成する方
法、さらには、特開昭６１−２４２２５６号公報に記載
されているように、溶射によって凹凸面を形成する方法
等がある。Conventionally, as a treatment method for forming a non-slip surface on the surface of such ceramic products, there is a method of forming irregularities on the surface by pressing at the stage of raw material, and a method of forming unevenness on the surface of the ceramic product by pressing, as described in Japanese Patent Application Laid-open No. 60-208554. There is a method in which fine particles having a melting point higher than the glaze firing temperature are mixed into the glaze to form an uneven surface during glaze firing.Furthermore, as described in Japanese Patent Application Laid-Open No. 61-242256, an uneven surface is formed by thermal spraying. There are various methods of forming it.
しかしながら、プレスによって凹凸を形成する方法にお
いては、凹凸模様が単純過ぎて微妙な凹凸模様の形成は
できないという欠点がある。However, the method of forming the unevenness by pressing has a drawback that the uneven pattern is too simple and it is not possible to form a delicate unevenness pattern.
また、釉薬中に微細粒子を混入する方法では、凹凸面が
釉薬によって被覆され、しかも、微細粒子を使用しなけ
ればならないことから、滑り止め効果も余り期待できず
、その上、その滑り止め効果も永続しないという欠点が
ある。In addition, in the method of mixing fine particles into the glaze, the uneven surface is covered with the glaze, and since fine particles must be used, the anti-slip effect cannot be expected much; The disadvantage is that it is not permanent.
さらに、溶射による凹凸形成は素地と溶射材との密着性
に問題があり、溶射層が素地表面から剥離し易いという
欠点を有していた。Furthermore, the formation of irregularities by thermal spraying has a problem in the adhesion between the base material and the sprayed material, and has the disadvantage that the sprayed layer is likely to peel off from the surface of the base material.
本発明は、このような従来方法による諸欠点を解消して
、比較的簡単な工程によって、永続的な滑り防止の凹凸
面を得ることができる窯業製品への滑り止め凹凸を形成
する方法を提供することを目的とする。The present invention provides a method for forming anti-slip irregularities on ceramic products, which eliminates the various drawbacks of the conventional methods and provides a permanent anti-slip irregular surface through a relatively simple process. The purpose is to
本発明の滑り止めを形成する処理方法は、焼成温度より
融点が高い材料と低い材料とをそれぞれ造粒して混合し
、これを窯業製品素地表面にプレス被覆し、焼成するこ
とを特徴とする。The treatment method for forming a non-slip according to the present invention is characterized by granulating and mixing a material with a melting point higher than the firing temperature and a material with a melting point lower than the firing temperature, press-coating this onto the surface of a ceramic product base, and firing. .
凹凸形成用の被覆材の焼成温度は、窯業製品によって異
なるが、通常のタイルの場合、吸水率を低くする等の点
から、１１５０〜１３００℃の温度が通常である。The firing temperature of the coating material for forming unevenness varies depending on the ceramic product, but in the case of ordinary tiles, the temperature is usually 1150 to 1300°C from the viewpoint of lowering the water absorption rate.
同温度で焼成するに当たって、被覆材の素地上への密着
性と強度の点から、低融点材料としては焼成温度におい
てブライト釉薬となるもので、融点が１１００℃程度の
ものが望ましい。When firing at the same temperature, from the viewpoint of adhesion of the coating material to the substrate and strength, the low melting point material is preferably a material that forms a bright glaze at the firing temperature and has a melting point of about 1100°C.
また、高融点材料としては、その焼成温度よりも高融点
を有する素地原料と同組成の原料を使用する。Further, as the high melting point material, a raw material having a melting point higher than the firing temperature and having the same composition as the base raw material is used.
それらの混合物を造粒するに際しては、とくに高融点材
料として０．１〜５ｍｍ程度に造粒したものが、凹凸の
高低差（落差）による滑り止め効果の点から望ましい。When granulating such a mixture, it is particularly desirable to use a high melting point material granulated to a size of about 0.1 to 5 mm from the viewpoint of anti-slip effect due to the height difference (head) of the unevenness.
窯業製品素地表面に被覆された造粒混合物を融点の低い
材料のみを融解する温度に加熱焼成することによって、
融解した低融点材料が表面張力によって高融点の粒子を
取り囲んだり、粒子間の隙間に入り込んだりして、高融
点の材料を残して低融点の材料の部分が窪むことにより
、極めて不規則で、且つ滑り止め機能を発揮する充分な
落差を有する凹凸を形成する。By heating and firing the granulated mixture coated on the surface of the ceramic product base to a temperature that melts only the material with a low melting point,
Due to surface tension, the melted low melting point material surrounds the high melting point particles or enters the gaps between the particles, leaving the high melting point material behind and the low melting point material becomes depressed, resulting in extremely irregular , and form irregularities with a sufficient height to exhibit an anti-slip function.
低融点と高融点の粉末材料を造粒した混合物を使用すれ
ば、単に粉末混合物を使用する場合とは異なり、各造粒
物の粒径を調整することにより、素地表面の凹凸状態を
任意に調整することができる。By using a granulated mixture of low-melting point and high-melting point powder materials, unlike the case of simply using a powder mixture, by adjusting the particle size of each granule, it is possible to arbitrarily create unevenness on the substrate surface. Can be adjusted.
また、釉薬中に高融点微粉末を使用する場合と異なり、
高融点材料の各粒子が、低融点材料に包み込まれること
により、微細な窪みや角部が少なく、滑らかな表面が得
られるので、ゴミがたまりにくいという効果がある。Also, unlike when using high melting point fine powder in the glaze,
Since each particle of the high-melting point material is wrapped in the low-melting point material, a smooth surface with fewer microscopic depressions and corners is obtained, which has the effect of preventing dust from accumulating.
