Abstract

The invention relates to a magnesium oxysulfate cement lightweight foaming brick and a preparation method thereof. Specifically, the magnesium oxysulfate cement lightweight foaming brick is prepared from the following components in parts by weight: 100 parts of magnesium oxide, 50-85 parts of a magnesium sulfate solution, 100-300 parts of a filling material, 0.1-0.5 part of a first additive, 0.5-5 parts of a second additive, 20-35 parts of a reinforcing agent, 10-25 parts of a flame retardant, 5-15 parts of a foaming agent, and 0.5-5 parts of an organosilicon water repellent, wherein the first core additive is an inorganic acid or inorganic salt, and the second core additive is an organic acid or organic salt. The magnesium oxysulfate cement lightweight foaming brick provided by the invention is excellent in compression resistance and fracture resistance, strong in water resistance, good in heat preservation and flame-retarding effects, and capable of resisting active magnesia and scumming.

Description

technical field [0001] The invention relates to the field of a compound building material formula and its preparation process, in particular to a foamed brick produced by using magnesium desulfurization by-products and its preparation process. Background technique [0002] Foamed bricks are divided into full cement foamed bricks and concrete foamed bricks according to different processing raw materials. As a necessity of building materials, they are widely used in various fields of construction, such as insulation filling for firewalls, sound insulation floor filling, tunnel filling, etc. Liner backfill, isolation of power and water pipelines, thermal insulation materials, etc. It has the characteristics of good sound absorption effect, good fire and heat insulation, light weight and strong shock resistance, non-toxic and harmless, environmental protection and energy saving, etc. [0003] With the continuous development of modern construction buildings, prefabricated buildi...
