Abstract

The invention discloses a lightweight soundproof thermal insulation wall brick. The wall brick is prepared from, by weight, 170-190 parts of silica sand, 80-90 parts of cement, 35-45 parts of lime, 17-24 parts of ardealite, 25-35 parts of coal ash, 0.3-0.5 part of aluminum powder, mica powder and 320-360 parts of water, wherein the mica powder accounts for 7-9% of the total dry weight. Compared with an organic foaming method, an inorganic foaming method has advantages of high corrosion resistance, fireproof performance and environment friendliness. The wall brick prepared from the raw materials according to the method is about 0.34g / cm<3> in bulk density, 1.6Mpa in compressive strength, 0.07W / m.K in thermal conductivity and 40db in soundproof effect.

Description

Technical field [0001] The invention relates to the technical field of building filling materials, in particular to a foamed wall brick and a manufacturing method thereof. Background technique [0002] Normal indoor partition walls are made of lightweight bricks, and the density of lightweight bricks is only 600-700Kg / m 3 , Lightweight bricks generally refer to foamed bricks. At present, more foamed bricks mainly use organic foaming technology, and organic foaming mainly has the disadvantages of poor anti-corrosion and fire resistance. Lightweight bricks can not only effectively reduce the load on the floor, but also have good sound insulation and heat insulation effects, but the strength of lightweight bricks is poor. For example, the Chinese patent with application number 01310397200.0 discloses a lightweight wall brick with a density of 650Kg / m 3 , The compressive strength is 1.6Mpa. Therefore, how to obtain lighter and stronger wall tiles is a subject that is always pursued ...
