【発明の詳細な説明】
本発明は磁器質体にセメントモルタルを強固に
接着する方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for firmly adhering cement mortar to a porcelain body.
磁器質体とは吸水率が４％以下の焼成物で、耐
候性が優れ、強度が大きいためタイルとして建築
物の壁面の外装などに多く用いられる。しかしこ
れらは、吸水率が小さいために水のぬれが悪く、
このままセメントモルタルで接着施工することが
できない。 Porcelain is a fired product with a water absorption rate of 4% or less, excellent weather resistance, and high strength, so it is often used as tiles for the exterior of building walls. However, these have poor water wettability due to their low water absorption.
It is not possible to perform adhesive construction using cement mortar as it is.
タイルにはセメントモルタルの接着性をよくす
るために吸水率を４％以上にしたものもある。し
かしこの吸水率の大きいものは厳冬期に水分が凍
結し割れを生じることがあるため外装用としては
使用することができず専ら内装に用いる。このよ
うな観点から外装用タイルは吸水率を２％程度に
抑えてあるのでセメントモルタルの接着について
はますます不利であることが知られている。 Some tiles have a water absorption rate of 4% or more to improve the adhesion of cement mortar. However, materials with a high water absorption rate cannot be used for exterior applications because they can freeze during the harsh winter months and cause cracks, and are used exclusively for interior applications. From this point of view, it is known that the water absorption rate of exterior tiles is suppressed to about 2%, which is increasingly disadvantageous in terms of adhesion with cement mortar.
本発明者らはこのような欠点を解消するために
種々検討した結果、磁器質体の板面に予めカルシ
ウムを含む無機化合物（以下プライマーという）
を塗布し、次いで加熱すると、カルシウム化合物
の結晶層が表面に形成され、セメントを水和結合
する表面に変成することを見い出した。 As a result of various studies in order to eliminate these drawbacks, the present inventors found that an inorganic compound containing calcium (hereinafter referred to as a primer) was applied to the surface of the porcelain body in advance.
It has been found that when applied and then heated, a crystalline layer of calcium compounds is formed on the surface, transforming it into a surface that hydrates the cement.
磁器質体は予め焼結したものを用いるが、焼結

ち、焼結前の磁器質体の板面にカルシウムを含む
無機化合物を塗布し、加熱することにより磁器質
体自体を焼結すると同時にその表面にカルシウム
化合物の結晶層を形成することができる。 The porcelain body used is one that has been sintered in advance, but it is also possible to use a porcelain body before sintering. That is, by applying an inorganic compound containing calcium to the plate surface of the porcelain body before sintering and heating it, it is possible to sinter the porcelain body itself and simultaneously form a crystalline layer of a calcium compound on its surface.
無機化合物としてはポルトランドセメント、ア
ルミナセメントといつたカルシウムを多量含有す
るセメントが使用可能である。 As the inorganic compound, cements containing a large amount of calcium such as Portland cement and alumina cement can be used.
本発明の方法における加熱処理の温度は、1300
℃以下であることが必要である。すなわち加熱処
理温度が1300℃以上になると無機化合物が劣化し
て磁器質体表面にカルシウム化合物の結晶層が形
成されなくなる。 The temperature of the heat treatment in the method of the present invention is 1300
The temperature must be below ℃. That is, when the heat treatment temperature is 1300° C. or higher, the inorganic compound deteriorates and a crystalline layer of the calcium compound is no longer formed on the surface of the porcelain body.
以下、タイルにセメントモルタルを接着する本
発明の実施例について説明すれば次のようにな
る。 Hereinafter, embodiments of the present invention for bonding cement mortar to tiles will be described as follows.
プライマーはポルトランドセメント100重量部

温度で加熱する。この加熱処理によつてタイルの
接着面はセメントモルタルと水和反応を生じる表
面に変性した。 The primer was prepared by adding 0.5 parts by weight of methyl cellulose to 100 parts by weight of Portland cement and 200 parts by weight of water. The primer is applied with a brush to the dry-formed tile substrate and then heated to a temperature of 1250°C. This heat treatment transformed the adhesive surface of the tile into a surface that would undergo a hydration reaction with cement mortar.
該タイルを、従来の未処理タイルと比較するた

28日間放置後、建築研究所式接着力試験機にかけ
て強度を測定した。その結果、プライマー処理し
たタイルは９〜20Kg／cm2の強度を示し、10個の平
均は15Kg／cm2であつた。同時にテストした未処理
タイルは３〜15Kg／cm2、10個の平均5.5Kg／cm2の
強度を示したにすぎず、本発明方法は優れた接着
強度を有することが明らかである。 In order to compare the tiles with conventional untreated tiles, we installed them on a wall using a common mortar bonding method.
After being left for 28 days, the strength was measured using a Building Research Institute type adhesion tester. As a result, the primed tiles showed a strength of 9-20 kg/cm 2 , with an average of 15 kg/cm 2 . The untreated tiles tested at the same time showed a strength of only 3 to 15 Kg/cm 2 , with an average of 10 pieces of 5.5 Kg/cm 2 , demonstrating that the method of the invention has excellent bond strength.
上述したように本発明は、磁器質体にプライマ

をなし得るものである。 As described above, in the present invention, a composite board of cement mortar and porcelain material can be made by applying a primer to a porcelain material and heat-treating it, and when used on a building wall as an exterior surface, it is strong. It is possible to perform adhesive construction.
