Problems solved by technology

[0004] However, the high-temperature one-time firing technology tends to bring about the following prominent problems: (1) In the current traditional one-time firing process, the clay content in the green body formula generally exceeds 20%, and the overall loss on ignition of the green body is relatively large. (2) Due to the simultaneous completion of the blank glaze at high temperature, the technical level and production process management requirements for transparent microcrystalline dry particles are very strict, and the overall production rate is low. It is difficult for the final product to meet the acid and alkali resistance index
However, the brick body prepared by the technology disclosed in this patent has poor high temperature stability and wear resistance needs to be enhanced

Abstract

The invention discloses a preparation method for producing ceramic foam boards by using lepidolite tailings. The ceramic blank formula of the ceramic foam boards is as follows by weight: 47-57 parts of lepidolite tailings, 5-11 parts of clay, and 20-20 parts of polishing slag. 30 parts, 1-4 parts of reinforcing agent, 3-7 parts of kaolin, 1-3 parts of talcum powder, 2-4 parts of silica, 1-5 parts of silicon slag, 1-3 parts of domestic waste incineration fly ash, prepared by the present invention The wear resistance of the surface of the ceramic foam board has been significantly improved, the high temperature stability has been enhanced, and the shrinkage of the foam board has been enhanced at the same time. During use, the surface is not prone to scratches and its service life is also extended.

Description

technical field [0001] The invention belongs to the technical field of building engineering materials, and in particular relates to a preparation method for producing ceramic foam boards by utilizing lepidolite tailings. Background technique [0002] Ceramic foam board is a kind of high-content inorganic silicate mineral material as the main raw material, which has high fire insulation performance, low thermal conductivity, new light weight, stable chemical performance, non-toxic and tasteless, good anti-corrosion and moisture-proof performance, sound insulation and noise reduction. , High waterproof and hydrophobic performance, strong weather resistance and other characteristics of the board body material. As a building material, it has great use value and scope of use. [0003] At present, most of the transparent glass and overglaze color ceramic composite board products on the market adopt a cumbersome secondary firing process, a long production cycle (over 4 hours in to...
