Abstract

The invention discloses a modified buckwheat hull foam brick and a preparation method thereof. The foam brick is characterized in that the foam brick is prepared from the raw materials of, by weight, 50-60 parts of waste glass, 20-30 parts of modified buckwheat hull, 10-15 parts of attapulgite, 3-5 parts of calcium oxide, 1-2 parts of polyethylene glycol, 0.5-1 parts of sodium lauryl sulfate, 1-2 parts of potassium fulvate, 0.5-1 parts of sodium carboxymethyl cellulose, 6-8 parts of linseed oil, 1-2 parts of styrene-acrylic emulsion, 2-4 parts of organosilicon quaternary ammonium salt, 0.2-0.4 parts of sodium dodecylbenzene sulfonate, and 50-60 parts of water. According to the foam brick provided by the invention, through improvements in formula and process, the product has the characteristics of good thermal insulation, light weight, high strength, antibacterial property, and mildew resistance. With the method, energy is saved, waste is utilized, and cost is low.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a modified buckwheat hull 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, which ...
