Abstract

The invention discloses a method for producing an inorganic insulation fire-proof plate by using industrial by-product gypsum, comprising the following steps that: 1-5 weight portions of blowing agent and 1-5 weight portions of foaming agent are added in 40-60 weight portions of warm water to foam; 650-750 weight portions of industrial by-product gypsum, 25-35 weight portions of metakaolin, 15-25weight portions of alum, 90-105 weight portions of cement, 30-70 weight portions of steel slag, 45-55 weight portions of flyash, 45-55 weight portions of calcium peroxide are mixed with 80-120 weight portions of water with stirring uniformly, added in the foamed liquid and put in an abrasive tool to maintain for 24h, then are subject to demolding. The inorganic insulation fire-proof plate produced by the method disclosed by the invention with adding more than 60wt% of industrial by-product gypsum belongs to a typical energy-saving novel material with the advantages of thermal insulation, A1 level fire prevention and the like, capable of meeting the national requirements of saving energy and digesting more industrial by-product gypsum.

Description

technical field [0001] The invention relates to a production method of an inorganic thermal insulation board, which is mainly applied to the thermal insulation of exterior walls or interior walls in the construction industry, and in particular relates to a method for producing an inorganic thermal insulation fireproof board with industrial by-product gypsum. Background technique [0002] In 2009, my country's industrial by-product gypsum produced about 118 million tons, and the comprehensive utilization rate was only 38%. Among them, desulfurization gypsum is about 43 million tons, with a comprehensive utilization rate of about 56%; phosphogypsum is about 50 million tons, with a comprehensive utilization rate of about 20%; other by-product gypsum is about 25 million tons, with a comprehensive utilization rate of about 40%. At present, the cumulative stockpiles of industrial by-product gypsum have exceeded 300 million tons, including more than 50 million tons of desulfurized ...
