Ceramic plate

Abstract

The invention provides an argil plate and belongs to the technical field of building materials. The ceramic plate is prepared from the following materials in parts by weight: 10-35 parts of illite, 0-15 parts of kaolin, 5-15 parts of pyrophyllite, 5-30 parts of chinastone, 20-50 parts of iron ore smelting tailings, 5-30 parts of coarse poor materials, 0-5 parts of plasticizers, 20-40 parts of argil dry powder, 20-30 parts of chinaclay dry powder, 10-20 parts of feldspar powder and 20-30 parts of aggregate. The aggregate is prepared by crushing waste ceramic plates, ceramic tiles, pottery tiles and leftover materials; the fineness of the aggregate is 12-60 meshes. The argil plate is free of stone radiation and harm of organic materials of artificial stone to people; after the ceramic plate is fired under high temperature, the ceramic plate is high in strength, never fades and is free of influence of climatic environment; the coarse aggregate is added into the formula, so that the surface of the ceramic plate is rough and is not slippery; the argil plate is rapid to extrude and form, high in drying qualification rate and short in firing period; the cost is reduced; the iron ore tailings are used, so that the local industrial waste residues are reused.

Description

technical field [0001] The invention relates to a clay board, which belongs to the technical field of building materials. Background technique [0002] Clay refers to clay that contains iron and has yellowish-brown, off-white, reddish-purple hues, and has good plasticity. Clay is the raw material for pottery. The mineral composition is complex, mainly composed of kaolinite, hydromuscovite, montmorillonite, quartz and feldspar. The particle size is inconsistent, often containing sand, silt and clay. It is hygroscopic and absorbent, and can be plasticized after adding water. The color is impure, often with yellow, gray and other colors, so it is only used for pottery making. Clay is mainly used for firing exterior walls, floor tiles, pottery utensils, etc. Clay has the following properties: [0003] 1. Excellent anti-freezing and thawing characteristics: when the water absorption rate reaches 10%, porcelain bricks have been frozen and thawed three times at -15°C and have...

Problems solved by technology

The pure natural processing process makes the clay brick itself contain only a small amount of chemical impurities, and its internal structure is not easily affected by acid rain. The clay's anti-alkali corrosion characteristics are even more incomparable to other materials.
