Problems solved by technology

Due to the high content of Al 2 O3, Fe 2 o 3 and TiO 2 and other coloring components, the existing porcelain polished tiles generally have poor whiteness, poor light transmission, poor jade texture and other shortcomings, which affect the decorative effect of polished tiles
Unable to meet people's demand for high-quality polished tiles

Embodiment 1

[0010] 1. The raw materials are mainly composed of the following components by weight: 50% high white superfine quartz powder, 15% nepheline, 20% albite, 12% clay raw materials, 3% dolomite, 0.5% modified lignin, Sodium Carboxymethyl Cellulose 0.2%.

[0011] 2. The production method of the porcelain polished tile: the raw materials formulated according to the above-mentioned requirements are batched into the ball mill by a forklift, and 45% of the total weight of water and 0.5% water-reducing agent water glass are added simultaneously to improve the ball-milling efficiency. The milling fineness is controlled at 0.2-0.5% of the sieve with ten thousand holes. The mud goes through three times of repeated iron removal and sieving to ensure the removal of unground raw materials and impurity iron. The obtained mud is spray-dried to obtain a powder with a water content of 5-7%. Particle gradation: 6-12% for larger than 30 mesh; ≥70 for 30-60 mesh; ≤12 for 60-80 mesh; ≤5 for smaller...

Embodiment 2

[0013] 1. The raw materials are mainly composed of the following components: high white superfine quartz powder 55%, nepheline feldspar 25%, albite 5%, clay raw materials 12%, calcite 3%, polyvinyl alcohol 0.3%, carboxymethyl Sodium Cellulose 0.1%.

[0014] 2. The manufacture method of this porcelain polished tile: the difference with embodiment one is that the green body after drying first prints the seepage glaze containing soluble salt solution on its surface (as added in 10% sodium dichromate solution 2% high-viscosity sodium carboxymethylcellulose thickens to form a paste), spray an appropriate amount of permeable water on the surface of the brick to allow the soluble salt to penetrate into the body to a certain depth with the water, and then enter the kiln for firing.

Abstract

This invention discloses a technique for producing ceramic polished bricks. The raw materials comprise: high-whiteness ultra-fine quartz powder 45-60 wt.%, feldspar flux 15-35 wt.%, clay 5-20 wt.%, Ca-Mg raw material 0-8 wt.%, and strengthening agent 0.1-1 wt.%. The method comprises: preparing the raw materials, ball-milling, sieving, removing Fe, spray-drying to obtain powder, aging, pressing, drying, sintering, polishing, and screening. The introduction of large amounts of quartz, feldspar flux and strengthening agent can reduce the consumption of clay, and improve the whiteness and light permeability of the ceramic polished bricks. The ceramic polished bricks have such advantages as high whiteness, no radioactivity, high light permeability and good appearance.

Description

Technical field: [0001] The invention relates to the technical field of building decoration materials, in particular to a porcelain polished tile with high quartz content and a manufacturing process thereof. Background technique [0002] At present, porcelain polished tiles are generally made by mixing barren raw materials such as potassium feldspar, albite, porcelain stone, and black talc with clay-like plastic materials in a certain proportion and grinding them to a certain fineness by a ball mill, and then spraying powder, Compression molding, drying and firing. Its chemical composition is roughly: SiO 2 64%~73%, Al 2 o 3 15%~22%, Fe 2 o 3 iO20.5~2%, CaO+MgO0.5%~3%, K 2 O+Na 2 O 3% to 6%. Due to the high content of Al 2 O3, Fe 2 o 3 and TiO 2 and other coloring components, the existing porcelain polished tiles generally have poor whiteness, poor light transmission, and poor jade texture, which affect the decorative effect of the polished tiles. It cannot sati...
