Abstract

The invention discloses a sound insulation building material which includes a sound insulation base material and a sound insulation binder. The sound insulation binder is used for binding the sound insulation base material onto a building wall. The raw materials for preparing the sound insulation base material include cement, fly ash, wood fibers, diatomite, plant fibers, a foamer, a foam stabilizer, hollow glass micro-beads, PVC resin, low-density polyethylene, rubber, barium sulfate and aluminum sulfate. Through change on ingredient and ratio of the raw materials, the molecular binding property of the materials is excellent and the distribution of the materials is uniform in the sound insulation building material. The sound insulation building material can block noise at low frequency, thus achieving an excellent sound insulation effect.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a sound-insulating building material. Background technique [0002] Existing building materials such as cement mortar are widely used due to their easy construction and high strength. However, with the improvement of user needs, the requirements for sound insulation performance of building materials are getting higher and higher. Sound insulation materials generally require high density and large thickness. At present, the density of composite building materials on the market is small, and the sound insulation effect is not obvious after the construction is completed. In order to achieve the purpose of sound insulation, it is often achieved by adding sound insulation cotton or sound insulation layer to the wall of the building, which is expensive and increases the difficulty of construction. . Noise has become a major environmental pollution, and the acoustic environment of bui...
