Problems solved by technology

[0005] Therefore, the present invention proposes a fiber-reinforced silicate fire-proof board produced by mixing industrial waste slag from the perspective of utilizing waste materials, selects the waste slag of polished bricks as the main siliceous material, and selects calcium carbide slag as the main calcareous material to solve the problem of polishing. Brick waste slag has many impurities, the overall density is high, and it is easy to settle. It is difficult to be suitable for production on the flow line, and the product quality is not easy to guarantee.

Abstract

The invention discloses a fiber reinforced silicate fireproof board produced by doping industrial waste residue. The fiber reinforced silicate fireproof board comprises, by mass, 7-15% of cement, 20-30% of carbide slag, 20-35% of polished tile waste residue, 4-10% of metakaolin, 4-10% of aluminum hydroxide, 4-10% of mica, 3-6% of expanded perlite, 3-6% of expanded vermiculite, 6-8% of wood pulp fiber and 0.6-1.2% of bentonite. The polished tile waste residue is utilized to produce the fiber reinforced silicate fireproof board, so that a new path is provided for using the polished tile waste residue, production cost is low, the process is easy to realize, and the fiber reinforced silicate fireproof board has remarkable substantial effect on utilization of the polished tile waste residue and environment protection. The fiber reinforced silicate fireproof board has low heat conducting coefficient and high high-temperature size stability and can be used for face boards of passive fireproof system of various buildings.

Description

technical field [0001] The invention relates to the technical field of silicate fireproof boards. More specifically, it relates to a fiber-reinforced silicate fireproof board produced by mixing industrial waste slag, its preparation method and application. Background technique [0002] Polished brick waste slag is the waste slag generated during the surface polishing process of ceramic tiles, and is a major ceramic solid waste. Because the silicon carbide and magnesium chloride that are ground off by the polishing grinding head during polishing will decompose gas during the firing process, and the product will foam, so it is not possible to use the waste of polished tiles to produce floor tiles that require high strength and wear resistance. product. Therefore, it is difficult for the corresponding manufacturers to directly recycle it. It is currently the most difficult to use waste residue in the ceramic industry, and it is also the least utilized waste residue. [0003]...
