Light thermal insulation soundproof damping floor mortar

Abstract

The invention discloses light thermal insulation soundproof damping floor mortar, which is prepared by mixing the following components in percentage by mass: 30 to 40 percent of cement, 0 to 28 percent of coarse elastic rubber aggregate, 5 to 50 percent of fine elastic rubber aggregate, 5 to 15 percent of inorganic vitrified microsphere aggregate, 0.5 to 3 percent of redispersible emulsion powder, 0.05 to 0.15 percent of cellulose ether, 0.02 to 0.06 percent of 6mm fiber and 0.05 to 0.1 percent of hectorite aid. Inorganic silicate is taken as a binding material, so the light thermal insulation soundproof damping floor mortar has good compatibility with cement mortar and a concrete base, is firmly bound, avoids a hollowing phenomenon, is suitable for various base conditions, has a leveling function under the condition of poor evenness, is easy and convenient to construct, and can be scraped after being added with water and uniformly stirred; the whole soundproof layer is a whole, sound bridges are greatly reduced, the compression strength is moderate, the deformation hardly occurs, and the load of a building cannot be increased greatly; and the light thermal insulation soundproof damping floor mortar has low coefficient of heat conductivity, makes floors soundproof, and has the thermal insulation effect.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a lightweight thermal insulation and sound insulation damping floor mortar. Background technique [0002] As early as 1988, my country promulgated the "Code for Design of Sound Insulation of Civil Buildings" (GBJ118-1988), which stipulated the allowable noise level in bedrooms and living rooms (halls), and the sound insulation that partition walls and floors should achieve. Over the past 20 years, residential design has made great progress. More and more attention has been paid to the energy-saving and thermal insulation performance of buildings. Soundproofing of the impact sound. Even if the residents buy high-priced houses, the impact sound insulation performance of the floor slabs may not meet the standard. Living in such impersonal buildings, the quality of life of the residents is greatly reduced. As the residents pay more attention to the quality of life, the...

Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of lightweight thermal insulation and sound insulation damping floor mortar for the deficiencies of the prior art. The mortar uses inorganic silicate as the cementitious material, so it has good compatibility with cement mortar and concrete base , the bond is firm, avoid hollowing, adapt to various base conditions, in the case of poor flatness, the mortar can also have a leveling function, the construction is very simple, just like other dry powder mortar products, just add water and stir evenly For batch scraping, the entire sound insulation layer is integrated, which greatly reduces the existence of sound bridges. The compressive strength is moderate, and it is not easy to deform. Moreover, the mortar will not greatly increase the load of the building, and has a very low thermal conductivity. Make the floor soundproof and have thermal insulation effect at the same time
