Soundproof building material

Abstract

The invention relates to the field of building materials, and particularly relates to a soundproof building material which can be used for effectively improving a soundproof effect. The soundproof building material is prepared from the following raw materials in parts by weight: 105 parts of cement, 70 parts of paddy-rice husk particle, 70 parts of pulverized fuel ash, 10 parts of wood fiber, 25 parts of flame retardant, 7 parts of powdery diatomite and 11 parts of hollow glass microsphere. Through adding the wastes of the pulverized fuel ash and the paddy-rice husk particle into the building material provided by the invention, the soundproof building material has an important meaning to environmental protection, and meanwhile, has the advantages of good soundproof effect and high strength.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a sound insulation building material capable of effectively improving sound insulation effect. Background technique [0002] Traditional building concrete uses cement as cementitious material, sand and stone as aggregate, and is mixed with water in a certain proportion to form. It has the characteristics of simple construction and high strength and is widely used. The requirements for sound insulation performance are getting higher and higher, and 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. It is realized by adding sound insulation cotton or sound insulation layer to the wall, which is expensive and increases the difficulty of building construction. SUMMARY OF THE INVENTION [000...

Problems solved by technology

[0002] Traditional building concrete uses cement as the cementitious material, sand and stone as the aggregate, and is mixed with water in a certain ratio to form it. It has the characteristics of simple construction and high strength and is widely used. The requirements for sound insulation performance 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 used in buildings It is realized by installing sound-proof cotton or sound-proof layer on the wall, which is expensive and increases the difficulty of construction
