Biomass ash-doped white glazed tile and preparation method thereof

The invention relates to a biomass ash doped white glazed tile and a preparation method thereof. A green body formula of the biomass ash doped white glazed tile comprises the following components in parts by weight: 10-20 parts of biomass ash, 25-40 parts of potassium sodium stone powder, 15-30 parts of polishing waste residues, 20-40 parts of mixed mud, 1-5 parts of a toughening agent and 0.1-0.5 part of a dispergator. The preparation method of the biomass ash-doped white glazed tile comprises the following steps: (1) grading and ball-milling a blank; (2) spray granulation; (3) pressing a green body; (4) applying cover glaze; (5) firing; the glossiness of the white glazed tile obtained after firing is 5-10 degrees; the whiteness is 70 to 85 degrees, the LAB value L is 82.1 to 98.5, the A value is-0.5 to 0.3, and the B value is-0.2 to 3.8; (6) polishing and brushing. 本发明涉及掺杂生物质灰渣白色釉面砖及其制备方法。掺杂生物质灰渣白色釉面砖，坯体配方按重量份由以下组分组成为：生物质灰渣10～20份，钾钠石粉25～40份，抛光废渣15～30份，混合泥20～40份，增韧剂1～5份，解胶剂0.1～0.5份。掺杂生物质灰渣白色釉面砖制备方法，包括：⑴坯料分级配
