[0030] glaze composition

[0031] The glaze layer composition according to the first embodiment of the present invention includes glass frit containing zirconium element and zirconium silicate particles.

[0032] In the glass frit of this embodiment, ZrO 2 In conversion, it is a glass frit containing a zirconium element in an amount of 1.0% by mass to 15% by mass, preferably a glass frit containing a zirconium element in an amount of 1.2% by mass to 10% by mass. According to a preferred embodiment, the frit is a zircon opaque frit. In this embodiment, when the glass frit containing the above-mentioned amount of zirconium is fired, microcrystals of zirconium silicate can be precipitated in the glassy matrix. According to a preferred embodiment, the particle diameter of the microcrystals is more than 0 μm and less than 0.3 μm.

[0033] In the present embodiment, the zirconium silicate particles are particles having an average particle diameter of not less than 0.4 μm and not ...

[0047] Components of this embodiment

[0048] According to this embodiment, there is provided a member including a substrate and a glaze layer on the substrate, wherein the glaze layer is composed of at least a first glaze layer and a second glaze layer on the first glaze layer. Composition of the glaze layer.

[0049] first glaze layer

[0050] In this embodiment, the first glaze layer contains white inorganic oxide particles and a vitreous component. The inorganic oxide particles contain Al and / or Zr, have a refractive index exceeding 1.7 and not more than 2.5, and have an average particle diameter of 0.4 μm. Above 5 μm and below.

[0051] In the first glaze layer, the white inorganic oxide particles are preferably at least one selected from the group consisting of zirconium silicate (refractive index 2), zirconia (refractive index 2.4), and alumina (refractive index 1.76). kind. These components have a higher refractive index than the vitreous component, and since parti...

[0098] Preparation of base material

[0099] After mixing dry powder composed of 50% wollastonite, 40% clay and 10% talc, water is added to prepare a plastic adobe. The adobe was shaped and rolled by an extruder to form a plain flat plate with a width of 600 mm, a length of 900 mm, and a thickness of 4 mm. After the plain slabs are dried, they are fired in a roller kiln at a maximum temperature of 1150°C.

[0100] Preparation of the first glaze composition

[0101] 40 parts by mass of feldspar, 15 parts by mass of kaolin, 15 parts by mass of zirconium silicate particles, and 30 parts by mass of glass frit mixed with zirconia particles are mixed with 40 parts by mass of water and pulverized with a grinder After 20 minutes, prepare the first glaze composition in the form of a slurry. The average particle diameter of the zirconium silicate particles used here is 0.8 μm.

[0102] Second glaze composition

[0103] Glass frits 1 and 2 having the compositions described in Table ...

Abstract

The invention discloses a glaze composition of a glaze layer, and a component of the glaze layer obtained by the composition. The composition and the component have good high diffuse reflectivity and further have stain resistance. The glaze composition contains frit containing zicconium element, and zirconium silicate particles. The glaze composition is characterized in that quantity of the zicconium element in the frit is more than 1.0% by mass and less than 15% by mass, converting by ZrO2. Average grain diameter of the zirconium silicate particles is more than 0.4 [mu]m and less than 5 [mu]m. The glaze layer formed by the glaze composition can effectively make light diffuse at wide angles in a wide wavelength range. In addiont, the glaze layer is not easy to infect dirt and has property that dirt can easily wiped off once the layer is dirty.

Description

technical field [0001] The present invention relates to a glaze composition, in particular to a glaze composition for forming a glaze layer on a heat-resistant base material, such as a wall material of a building, and a The building material of the glaze layer formed by the composition. Background technique [0002] Components, especially building materials, that diffuse, reflect, and brighten the surface and surroundings of visible light, for example, when used indoors, can make the interior feel bright even with little lighting. The result is savings in lighting energy costs. Furthermore, building materials that are easy to remove dirt are preferable. As a means of reflecting light at a wide angle, it is conceivable to make the surface into a concave-convex shape, but this is not generally a preferable shape in terms of contaminating the unevenness of the surface. [0003] Japanese Patent Laid-Open No. 2011-226156 (Patent Document 1) discloses a ceramic tile that can as...
