Abstract

The invention discloses a lightweight concrete heat preservation and sound insulation wall which comprises a base layer wall surface, the base layer wall surface is coated with a bottom layer, the bottom layer is coated with a surface layer, and the bottom layer is prepared from the following raw materials in parts by weight: 60-70 parts of high-strength gypsum, 10-20 parts of rubber, 5-10 parts of perlite, 0.5-2 parts of polyphenyl particles and 0.2-1 part of a modified additive. The surface layer is prepared from the following raw materials in parts by weight: 20-30 parts of high-strength gypsum, 10-15 parts of cement, 10-20 parts of sand, 20-30 parts of coal cinder and 0.2-1 part of an additive, and the modified filler is modified aerogel. The invention further discloses a preparation method of the lightweight concrete heat preservation and sound insulation wall. Under the condition of solving the problem that the original mortar is easy to cause hollowing and cracking, the heat conductivity coefficient is reduced, so that the thermal insulation effect is better, and the strength of the mortar is also improved.

Description

technical field [0001] The invention relates to the technical field of walls, in particular to a lightweight concrete heat-insulating and sound-insulating wall and a preparation method thereof. Background technique [0002] With the improvement of people's quality of life, the requirements for the environment are getting higher and higher. Generally, the wall is brushed with sound insulation mortar, but the cementitious material in the existing sound insulation sand is mainly made of cement. , cinder, sand and admixtures. Among them, cement is a hydraulic material. After the construction is completed, it needs 7 days of finished product maintenance before continuing to make the surface layer. Moreover, due to its own characteristics, cement, a cementitious material, is particularly easy to cause hollowing and cracking, which will cause great damage to the later maintenance. Therefore, how to improve the existing problems is an urgent problem to be solved. Contents of the ...
