Method for producing phase-separated kiln-changing decorative composite material through roller kiln using red mud

Abstract

The invention belongs to the technical field of building ceramic production, and in particular relates to a method for producing phase-separated kiln-transformed decorative composite materials by using red mud through a roller kiln. Use red mud, feldspar, vanadium-titanium slag, quartz, borax, lepidolite and talc as raw materials, put it in a frit furnace, melt it at 1400-1500°C, water quench, crush and sieve, and take the sieved residue The materials are mixed together, which is the raw material for phase-separation kiln transformation; feldspar, clay, coke gemstone, pyrophyllite and avenzu stone are used as raw materials, put them in a ball mill, after 36 hours of ball milling, spray granulation, and put the granules in the mold , through pressing and forming to obtain a green body; the prepared phase-separation kiln transformation raw material is spread on the green body, and then dried and fired in a roller kiln to produce a phase-separation kiln transformation decorative composite material. The phase-splitting kiln-changing decorative composite material produced by the invention can meet all the performance and decoration properties of traditional ceramics, and does not use glaze pigments in the production process, which is a green and environment-friendly production process.

Description

technical field [0001] The invention belongs to the technical field of building ceramic production, and in particular relates to a method for producing phase-separated kiln-transformed decorative composite materials by using red mud through a roller kiln. Background technique [0002] In recent years, with the continuous improvement of the industrial level, the number of industrial products in China has increased significantly, so the discharge of industrial solid waste is very large. Among them, red mud, as an industrial by-product of alumina, has an annual discharge of more than several million tons , the annual discharge of vanadium-titanium slag is more than 20 million tons. The technology of developing and utilizing these solid wastes is also constantly developing, but they are mainly focused on using them as low value-added directions such as roadbed filling materials. However, when red mud is used as a raw material for ceramic matrix composites, its color, viscosity ...

Problems solved by technology

[0004] (1) Phase-separated glazes often need to be laid out twice, first with a layer of base material, and then with a layer of phase-separated raw materials, using the difference in viscosity of the two glazes at high temperature to make the crystal phase from the phase separation produce a kiln effect , if only one layer of material can be used to realize the production method of phase separation kiln transformation effect, the production efficiency can be greatly improved. ZL201210094756.8 discloses a production method using spodumene, quartz, calcite, talc, aluminum oxide, zinc oxide, , zircon powder, ashes, lithium carbonate and boric acid and other raw materials to prepare the basic crystal glaze, and then add cerium oxide, nickel oxide, manganese dioxide, iron oxide, titanium dioxide, cobalt oxide or copper oxide as colorants, and then fire it in a roller kiln The glass-ceramic composite plate mainly uses spodumene, but its basic crystalline glaze and coloring agent are mainly chemical raw materials, the cost is too high, and the application field of the product is limited

The use of solid waste, such as red mud and vanadium-titanium slag, as the main raw material for phase-separation crystallization kiln transformation can greatly reduce production costs. The kiln production process has been reported on the firing of phase-separated kiln-changing decorative composite materials, but has not been found
