Porcelain plate with glittering grain effect and manufacturing method thereof

Abstract

The invention provides a porcelain plate with a glittering grain effect and a preparation method thereof. The porcelain plate comprises a bottom blank and a blank face decoration layer, the blank face decoration layer sequentially comprises a ground glaze layer, a pattern layer, a protection layer, a glittering grain layer and a transparent layer, the ground glaze layer is connected with the bottom blank, and the preparation method comprises the following steps: preparing raw materials of the bottom blank for standby application; pressing the bottom blank and drying the bottom blank; spraying ground coat on the surface of the dried bottom blank to form the ground glaze layer; printing patterns on the surface of the ground coat layer to form the pattern layer; arranging the glittering grain layer on the surface of the pattern layer; arranging the transparent glaze layer on the glittering grain layer; firing and cooling; and polishing and grinding the edge to obtain the product; the surface of the product is smooth and free of spots and flaws, the flashing crystal grains completely covering the lower portion of the transparent layer have the better characteristics that the flashing effect is richer, the stereoscopic impression is higher, and the higher requirements of consumers are met.

Description

technical field [0001] The invention belongs to the field of ceramic building decoration materials, and in particular relates to a porcelain plate with flashing grain effect and a manufacturing method thereof. Background technique [0002] In modern architectural decoration, natural stone has great advantages in terms of color, texture and presentation due to its natural characteristics, but as it is continuously mined, natural mineral resources are becoming increasingly scarce, so various artificial stones appear in various places. In decoration applications, with the continuous improvement of people's living standards, consumers have further increased requirements for the appearance and inner texture of artificial stone surfaces. There is a little bit of starlight effect. Therefore, the production of glittering grain products like crystal sand natural stone has become one of the directions pursued by the decorative building materials industry.

Problems solved by technology

[0003] Porcelain ceramic products pressed by a large-tonnage press and fired at a high temperature of about 1150°C-1220°C are favored by consumers because of their superior physical and chemical properties such as acid and alkali resistance, wear resistance, and high strength and hardness. The aesthetic effect is as realistic as natural stone. The ceramic industry is also working hard in this direction. It wants to develop a ceramic plate with a shiny grain effect on the surface, such as adding mica flakes or metal particle materials with different luster to the production material. However, Because this type of material does not have light transmission, it is only based on the reflective effect of the material surface, and the visual effect of layering and three-dimensional sense is still lacking. In addition, the melting point of this type of material is generally around 800 ° C, so it is fired at high temperature. The high-temperature firing process used to achieve better physical and chemical properties is not very good for this technical solution.
