Abstract

The invention discloses a foam brick produced from biogas residues. The foam brick is characterized by being prepared from the following raw materials in parts by weight: 60-70 parts of waste glass, 15-10 parts of biogas residues, 5-10 parts of attapulgite, 5-10 parts of plant ash, 3-5 parts of bamboo charcoal powder, 3-5 parts of sisal fiber, 2-4 parts of sodium tripolyphosphate, 2-4 parts of tartaric acid, 1-2 parts of carboxymethyl chitosan, 1-2 parts of lauryl sodium sulfate, 0.5-1 part of polyvinyl alcohol, 2-4 parts of a modifying additive and 50-60 parts of water. The waste residues generated by a biogas digester are recycled to produce the foam brick, the effects of saving resources, protecting environment and reducing cost are achieved, the product performance reaches the standard, and the foam brick is safe, harmless and high in environmental and economic benefits.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a foam brick produced by using biogas slag 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, ...
