Abstract

The invention relates to a sound insulation type building material which comprises cement, wherein each 100 kilograms of the cement comprises 10-15 kilograms of perlite powder, 5-10 kilograms of calcium sulfate particles, 5-10 kilograms of calcium silicate particles, 1-2 kilograms of dicumyl peroxide, 2-3 kilograms of magnesium oxide, 2-3 kilograms of zinc oxide, 1-2 kilograms of sodium borate, 1-2 kilograms of chlorinated polyethylene and 4-5 kilograms of iron powder. A sound insulation plate prepared from the sound insulation type building material has a good sound insulation effect, and the sound insulation amount is 70-80dB; furthermore, the sound insulation type building material is easy to manufacture and convenient to construct; the environmental pollution is avoided, and the cost is lower.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a sound-insulating building material and a production method thereof. Background technique [0002] Building materials are the material basis of construction engineering, and various materials are needed in the construction of buildings from the main structure to decoration. Noise has become a major environmental pollution, and the acoustic environment of buildings has attracted more and more attention. It is one of the most commonly used and most basic technical measures in building noise control engineering to select appropriate materials for sound absorption and sound insulation of buildings. The goals and focuses of sound absorption treatment and sound insulation treatment are different. Sound insulation treatment focuses on isolating the transmission of noise from the sound source room to adjacent rooms, so that adjacent rooms are free from noise interference. ...
