Abstract

The invention discloses a modified desulfurization gypsum foam brick which is characterized in that the foam brick is prepared from the following raw materials, by weight: 50-60 parts of waste glass, 3-5 parts of fly ash, 20-30 parts of modified desulfurization gypsum, 5-10 parts of light calcium carbonate, 0.5-1 parts of sodium glutamate, 0.5-1 parts of sodium dodecyl sulfate, 0.5-1 parts of sodium alginate, 0.5-1 parts of hydroxypropyl guar gum, 0.2-0.4 parts of sodium dodecyl benzene sulfonate, 0.5-1 parts of glycine, 2-4 parts of organosilicon quaternary ammonium salt, 3-5 parts of castor oil, 2-4 parts of peanut oil, and 50-60 parts of water. According to the invention, through formula and process improvements, the foam brick has the advantages of high strength, good water resistance, good thermal insulation, good antibacterial performance, and good mildew resistance. The foam brick is energy-saving and emission-reducing. Raw material sources are rich, and cost is low. The foam brick and the preparation method provide high social and economic benefits.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a modified desulfurized gypsum foam brick and a preparation method thereof. Background technique [0002] Foam brick is a kind of aerated concrete block. After using a foaming agent to physically foam through a foaming machine, the air bubbles are added to the slurry for mixing, pouring, and finally a foam brick with internal pores is obtained. Foam bricks are mainly used for non-load-bearing walls. They have the characteristics of low cost, light weight, and good thermal insulation effects. They have been widely used in industrial and civil buildings and are a wall material with good performance. [0003] Glass materials are indispensable and indispensable materials for people's daily life. The extensive use of glass also leads to the inevitable generation of a large amount of waste glass waste in daily production and life. The chemical properties of waste glass are stable, w...
