Abstract

The invention relates to the technical field of construction materials, and specifically relates to a sound absorbing brick capable of reducing noise pollution. The sound absorbing brick is mainly composed of diatomite, bio-carbon, ceramic sand, talcum powder, silica micro-powder, zirconium boride, a dispersant, an adhesive and water; wherein the particle size of the bio-carbon is 300 to 400 nm, the bio-carbon is prepared from cactus, sisal hemp, maguey leaf, leaf of gasteria duval, corn straw, ramie, flax, kendir, hemp, undaria pinnatifida, and sea tangle, and silica aerogel is loaded on thebio-carbon. Compared with a conventional sound absorbing brick containing mineral wool fibers, the provided sound absorbing brick has a greater sound absorbing coefficient, is capable of obviously reducing the noise pollution, meets the using requirements, has higher mechanical strength, and is more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a sound-absorbing brick capable of reducing noise pollution. Background technique [0002] Since the modern living environment is full of various noises, which affect people's production and life and endanger people's health, sound insulation of buildings is very necessary. Generally speaking, the sound insulation performance of a building increases as the thickness of the wall increases. However, as the thickness of the wall increases, the wall will be too heavy, which will cause a large structural load burden. Existing buildings mostly use sound insulation bricks to provide sound insulation and noise reduction functions. The sound insulation bricks currently used include ordinary hollow bricks and professional sound insulation bricks. The sound absorption effect of hollow bricks is only about 10%, and the sound insulation and noise reduction effect is average. Profe...
