Abstract

The invention provides a sound-absorbing wall brick and a preparation method thereof. The sound-absorbing wall brick is prepared from clay, an auxiliary material, cement and water through mixing and sintering, wherein the weights of the auxiliary material and the cement are respectively 30 to 50% and 10 to 20%, and the auxiliary material is prepared by mixing rosin and a calcium carbonate particle with a fineness of 8 to 20 meshes according to a weight ratio of 1: 30-50. The wall brick produced in the invention can be directly used for building walls or is stuck on the interior or exterior of the wall, thereby exerting an effect of absorbing indoor or outdoor noise; the wall brick can also be used for building protective guards at two sides of a road so as to obtain dual effects of protection and noise absorption.

Description

technical field [0001] The invention relates to building materials used in the construction field, in particular to a sound-absorbing wall brick and a preparation method thereof. Background technique [0002] Noise pollution is a very important part of urban pollution, and it is difficult to reduce and control it. In the prior art, some isolation boards are usually installed on both sides of the road to isolate the noise, which leads to high cost; while indoor noise is mainly absorbed by setting up sound-absorbing walls. The principle of sound-absorbing walls is to Use porous sound-absorbing materials on the walls and make an outer layer, which not only takes up a small amount of indoor area, but also leads to an increase in construction costs. Contents of the invention [0003] In order to solve the problems in the prior art that the sound-absorbing wall that absorbs noise takes up indoor area, has high construction cost and low strength, the present invention provides a...
