Abstract

The invention relates to a lightweight hollow brick and a making method thereof. The lightweight hollow brick is characterized in that the lightweight hollow brick comprises 35-45% of magnesium oxide (75% or more of MgO), 6-10% of magnesium chloride (90% or more of MgCl), 0.3-0.5% of a foaming agent, 1-3% of fiberglass, and the balance water. The making method of the lightweight hollow brick comprises the following steps: 1, dissolving magnesium chloride in water to obtain an aqueous solution of magnesium chloride; 2, mixing the aqueous solution of magnesium chloride with magnesium oxide; 3, adding the fiberglass, and stirring; 4, adding the foaming agent, stirring to form magnesium oxychloride cement, and filling the magnesium oxychloride cement to a die of the lightweight hollow brick; 5, carrying out model formation heating; 6, carrying out demolding maintenance; and 7, warehousing the above obtained finished product. The lightweight hollow brick has the characteristics of light weight, fire proofing, water proofing, shock proofing, anticorrosion, sound insulation, heat insulation, high strength, sawability and drillability.

Description

technical field [0001] The invention relates to a building wall material and a preparation method thereof, in particular to a light-weight hollow brick produced by a complete production line with magnesium oxide, magnesium chloride and a foaming agent as main raw materials and a preparation method thereof, which belongs to the field of the construction industry. wall technology field.
