Abstract

The invention discloses a sound insulation mortar and a preparation method thereof. The sound insulation mortar is prepared from the following components in parts by weight: 30-35 parts of sand, 10-12parts of cement, 5-6 parts of elastic damping particles, 2-3 parts of polyester fiber and 1-1.2 parts of cement foaming agent. The preparation method of the sound insulation mortar comprises the following steps that (1) the sand, the cement, the elastic damping particles, the polyester fiber and the cement foaming agent, in parts by weight, are prepared; (2) the sand, the cement, the elastic damping particles, the polyester fiber and the cement foaming agent, in parts by weight, are blended and stirred; and (3) detection and packaging are conducted. The sound insulation mortar can be widely applied to the building construction field.

Description

technical field [0001] The invention relates to a sound-insulating mortar and a preparation method thereof. Background technique [0002] With the development of science and technology, the requirements for buildings are getting higher and higher, and noise control is one of them. National standards have their requirements for the noise of building floors, such as GB / T50121-2005 "Evaluation Standard for Building Sound Insulation", GB 50118 -2010 "Code for Design of Sound Insulation of Civil Buildings", GB 50368-2005 "Code for Residential Buildings", GB / T 19889.7-2005 "Measurement of Sound Insulation of Acoustic Buildings and Building Components Part 7: On-site Measurement of Floor Impact Sound Insulation" There are requirements for this. At present, it is difficult for ordinary mortar to meet the corresponding requirements for controlling floor noise. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficie...
