Abstract

he invention relates to a foam cement insulation board and a preparation method thereof, and provides a foam cement insulation board containing industrial solid wastes and a preparation method thereof. The foam cement insulation board is composed of a mixture A and a mixture B. The mixture A comprises 55-65% of cement, 10-20% of gypsum powder, 8 -15% of hydrogen peroxide,3-4% of a flocculant, 1-2% of a water reducing agent, 1-2% of a coagulant, 2-3% of a cement waterproof agent, 1-2% of lithium carbonate, 1-2% of fiber, and 1-2% of solid master batch. The mixture B comprises 35-47% of a base material, 35-39% of a magnesium chloride solution, 10-15% of magnesium oxide, 2-5% of a binding agent, 2-3% of industrial hydrogen peroxide, 1-2% of lanthanide rare earth and 5-7% of an additive. The Foam cement insulation board provided by the invention has advantages of fireproof, waterproof, light weight, compressive and flexural resistance and high strength, and effectively utilizes industrial solid waste, facilitates environmental protection, and truly realizes turning wastes into treasures.

Description

technical field [0001] The invention relates to a foamed cement insulation board and a preparation method thereof, in particular to a foamed cement insulation board containing industrial solid waste and a preparation method thereof. Background technique [0002] With the development of industrial production, the amount of industrial waste is increasing day by day. Its passive stacking occupies land, pollutes soil, water and air, affects crop growth, and endangers human health. After industrial waste is generated, it must occupy an area and be piled up. The larger the amount of accumulation, the more land will be occupied. The waste is piled up, and the harmful components in it are easy to pollute the land. When pathogenic microorganisms and other harmful substances in polluted soil enter water bodies with natural precipitation, runoff or seepage, they may further endanger human health. Industrial solid waste also disrupts the ecological balance within the soil. Soil is a ...
