Novel environment-friendly high-temperature colored porcelain aggregate and preparation process thereof

Abstract

The invention discloses a novel environment-friendly high-temperature colored porcelain aggregate. The aggregate comprises the following raw materials in parts by weight: 5 to 95 parts of silicon dioxide; 1 to 95 parts of aluminum oxide; 0.0001 to 30 parts of ferric oxide; 0.0001 to 30 parts of calcium oxide; 0.0001 to 40 parts of magnesium oxide; 0.0001 to 20 parts of potassium oxide; 0.0001 to 20 parts of sodium oxide; 0.0001 to 20 parts of titanium dioxide; 0.00001 to 5 parts of phosphorus pentoxide; 0.00001 to 5 parts of manganese oxide; 0.00001 to 5 parts of chromium sesquioxide; 0.00001to 5 parts of zinc oxide; 0.00001 to 5 parts of lead oxide; 1 to 95 parts of zirconium oxide; 0.00001 to 5 parts of barium oxide; 0.00001 to 5 parts of strontium oxide; 0.00001 to 5 parts of diboron trioxide; 0.00001 to 5 parts of fluorine and 0.0001 to 10 parts of lithium oxide. The hardness, strength, wear resistance, fire resistance, skid resistance, firing and calcining temperature, application range and weather resistance of the novel environment-friendly high-temperature colored porcelain aggregate and the adhesive force with glue are greatly higher than those of an original product.

Description

technical field [0001] The invention relates to the technical field of porcelain material preparation, in particular to a novel environment-friendly high-temperature colored porcelain aggregate and a preparation process thereof. Background technique [0002] The existing product is very single in materials, and its calcined melting point temperature is 780 degrees (the product has melted into a liquid state). Disadvantages of its products: low firing and calcination temperature, low strength, low hardness (Mohs hardness 5-5.5), high water absorption rate of 3-7%, low density (1500-1800 kg / m3), paved on roads and expressways Not wear-resistant, poor anti-skid performance (because the purpose of anti-skid will be lost by the friction of automobile tires), fragile (because of the lack of a single chemical composition of raw materials), it cannot be used in areas with high external pressure, the firing temperature is low, and it is specially used for paving the ground The bondi...

AI Technical Summary

Problems solved by technology

[0002] The existing products are very simple in materials, and its calcined melting point temperature is 780 degrees (the product has melted into a liquid state)

Disadvantages of its products: low firing and calcination temperature, low strength, low hardness (Mohs hardness 5-5.5), high water absorption rate of 3-7%, low density (1500-1800 kg / m3), paved on roads and expressways Not wear-resistant, poor anti-skid performance (because the purpose of anti-skid will be lost by the friction of automobile tires), fragile (because of the lack of a single chemical composition of raw materials), it cannot be used in areas with high external pressure, the firing temperature is low, and it is specially used for paving the ground The bonding of the glue is poor (because the surface of the product is very smooth, which will affect the adhesion with the glue), and the weather resistance is poor (because the material is simple and the chemical composition is lacking). Therefore, we propose a new type of environmentally friendly high-temperature colored porcelain aggregate and its preparation process
