Preparation method of ceramic tile as well as ceramic tile and application thereof
The invention relates to the technical field of building materials, and discloses a preparation method of a ceramic tile, the ceramic tile and application of the ceramic tile. The method comprises the following steps: (1) carrying out ball milling or grinding on raw materials of a green body layer to prepare upper-layer powder and lower-layer powder; (2) performing compression molding on the upper-layer powder and the lower-layer powder, and drying to obtain a green body layer; (3) sequentially applying cover glaze, ink and transparent glaze on the green body layer, and firing; (4) applying the prime slurry to prepare the ceramic tile; in the step (1), the upper-layer powder and the lower-layer powder have the same composition, and the particle size of the lower-layer powder is larger than that of the upper-layer powder; in the step (4), the raw material of the prime pulp comprises magnesium oxide. The upper layer adopts the powder with the common particle size, and the lower layer adopts the powder with the large particle size, so that the roughness of the bottom layer of the blank layer is increased, and the bonding strength is further improved. The concentration of magnesium oxide in the prime slurry is reduced, so that the thickness of a prime slurry layer at the bottom of the ceramic tile is reduced, and the bonding strength of the ceramic tile is further improved.
本发明涉及建筑材料技术领域，公开了一种陶瓷砖的制备方法及其陶瓷砖与应用。该方法包括以下步骤：(1)将坯体层的原料进行球磨或研磨，制得上层粉料和下层粉料；(2)将上层粉料和下层粉料，压制成型，干燥，制得坯体层；(3)在坯体层上依次施面釉、墨、透明釉，烧制；(4)施用底浆，制得陶瓷砖；步骤(1)中，所述上层粉料和下层粉料的组成相同，所述下层粉料的粒径大于上层粉料；步骤(4)中，所述底浆的原料包括氧化镁。本发明通过在上层采用普通粒径的粉料和下层采用粗粒径粉料，使坯体层底层的粗糙度增大，进而提高粘结强度。并且通过降低底浆中氧化镁的浓度，从而减小陶瓷砖底部的底浆层厚度，进一步提高陶瓷砖的粘结强度。
