Abstract

The invention discloses a sound-absorption heat-insulation foamed brick. The invention is characterized in that the foamed brick is prepared from the following raw materials in parts by weight: 50-60 parts of waste glass, 5-10 parts of expanded vermiculite, 10-15 parts of pumice, 5-10 parts of nutshell, 3-5 parts of sawdust, 3-5 parts of calcium carbonate, 3-5 parts of peat, 1-2 parts of sodium phytate, 0.5-1 part of dimethyl silicone oil, 0.5-1 part of xylitol, 0.5-1 part of Turkey red oil, 1-2 parts of lauryl sodium sulfate, 0.5-1 part of polyvinyl alcohol, 2-4 parts of modifying assistant and 50-60 parts of water. The foamed brick has the advantages of favorable heat-insulation property and favorable sound-absorption effect, can effectively reduce noise and create a good living environment, and is suitable for use in habitable rooms.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a sound-absorbing and heat-insulating 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 st...
