Single-component lightweight sound-insulating heat-preserving mortar material and construction method thereof

Abstract

The invention discloses a single-component lightweight sound-insulating heat-preserving mortar material. The material is prepared from the following raw materials by weight: 350 to 700 parts of Portland cement, 500 to 1000 parts of lightweight porous slag, 6 to 12 parts of redispersible latex powder, 3 to 6 parts of cellulose ether, 20 to 40 parts of foam glass particle, 10 to 20 parts of a sound-insulating filling material, 20 to 40 parts of shale pottery and 1 to 2 parts of reinforced fiber. The single-component lightweight sound-insulating heat-preserving mortar material provided by the invention has scientifically and reasonably proportioned components, is extensively applicable to handling of walls, household floors and the like having requirements on sound insulation and heat preservation during building and brushing of the walls, casting of the household floors, etc., and has the advantages of sound insulation, heat preservation, fire prevention, water resistance, anti-freezing performance, good adhesion, no occurrence of cracking and hollowing, etc. The construction method for the material is reasonably designed, can mold a sound-insulating and heat-preserving system in a building wall or household floor in one shot and has the advantages of convenient construction, high efficiency, low cost, high quality, etc.

Description

technical field [0001] The invention relates to a building material, in particular to a single-component lightweight sound-insulating and heat-insulating mortar material capable of heat preservation, sound insulation, reliable quality, and simple construction. Background technique [0002] In response to the National Twelfth Five-Year Plan, the energy-saving level of residential buildings will reach 65%, as well as the building insulation and sound insulation requirements for green buildings. In view of the fact that existing building self-insulating wall materials, household walls, and household floors often fail to achieve 65% energy saving, it is urgent to make thermal insulation and sound insulation layers on the base walls and household floors as external wall insulation supplement. Traditional internal thermal insulation construction methods include: wall part a, cement-based inorganic light aggregate mortar internal thermal insulation system (JGJ 253-2011 Inorganic l...

AI Technical Summary

Problems solved by technology

[0004] However, the above method of thermal insulation and sound insulation of the wall and the method of thermal insulation and sound insulation of the household floor have some common shortcomings, such as: complex construction technology, high cost and difficult control of construction quality, resulting in hollowing, cracking, etc., which are very common and cannot meet the requirements.
