Abstract

The invention relates to energy saving soundproof mortar for a house wall. The energy saving soundproof mortar is characterized in that (1) the thermal performance and the soundproof effect of the mortar are improved by adopting a tri-admixture composite technology and the internal composite superimposed effect of materials; and (2) composite mixing is carried out on hollow float beads with closed cavity structures, EPS particles, rubber particles, cement, rubber powder, cellulose ether and fibers under the conditions that the temperature is greater than or equal to 5 DEG C, and the humidity is greater than or equal to 50%. The energy saving soundproof mortar has the advantages of simplicity in operation, strong cohesive force, non pollution, good thermal performance and soundproof performance and application to the soundproof and thermal insulation aspects of the house wall.

Description

technical field [0001] The invention relates to a wall mortar, in particular to an energy-saving and sound-proof mortar for a residential wall, which can satisfy multiple functions of thermal insulation and sound insulation of the residential wall. Background technique [0002] For the wall in the residential enclosure structure in the hot summer and cold winter area, heating needs to be considered in winter, and heat insulation, moisture-proof and waterproof functions need to be considered in summer. With the improvement of people's living standards, the functional requirements of sound insulation should also be considered. [0003] At present, the thermal insulation system used for residential walls includes internal thermal insulation, external thermal insulation and self-thermal insulation systems. The energy-saving products used mainly include EPS boards, XPS boards, rigid foam polyurethane sprayed external wall thermal insulation systems, and autoclaved aerated concrete...
