Description
Technical Field
The invention relates to the technical field of building materials, in particular to gypsum-based sound-insulation heat-preservation thick-layer self-leveling mortar.
Background
The self-leveling mortar comprises cement-based self-leveling/self-leveling mortar/leveling mortar and the like, and is a product with high technological content and relatively complex technical links. The material is a dry-mixed powder material consisting of a plurality of active ingredients, can be used after being mixed with water on site, and can obtain a high-level base surface after being spread by a scraper. The hardening speed is high, the walking can be carried out in 24 hours, or subsequent engineering (such as paving wood floors, diamond plates and the like) is carried out, and the construction is fast and simple and is incomparable with the traditional manual leveling.
Along with the improvement of living standard, people pay more and more attention to the performance of sound insulation and heat preservation of buildings, and the noise generated by the impact sound of the upper floor is very unpleasant, so that the sleeping of the residents on the lower floor is influenced, and the mood of the people is also influenced. At present, the sound insulation mortar on the market does not have the self-leveling performance, and the self-leveling performance does not have the sound insulation performance, so that the mortar with the sound insulation performance and the high performance of automatic leveling is urgently needed to meet the requirements of people on indoor buildings.
Disclosure of Invention
The invention aims to provide a gypsum-based sound-insulation heat-insulation thick-layer self-leveling mortar which is specially designed for high-rise floors, is used for reducing the dead weight of the floors and insulating heat and sound of floors, and aims to solve the problem.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: the gypsum-based sound-insulation and heat-insulation thick-layer self-leveling mortar comprises the following components in percentage by weight: 80-90% of mixed gelled material, 8-10% of mineral filler, 0.3-3.5% of retarder, 0.8-1.3% of rheology modifier, 0.0002-0.0005% of active excitant and 38-40% of water.
As an improvement, the mixed gel material comprises 25 percent of ordinary portland cement and α percent of semi-hydrated gypsum or anhydrite by weight percentage.
As an improvement, the mineral filler is vitrified micro bubbles.
As an improvement, the retarder is a gypsum retarder.
As an improvement, the rheology modifier comprises the following components in percentage by weight: 0.16-0.2% of HPMC water reducing agent, 0.1-0.15% of defoaming agent, 0.1-0.15% of cellulose No. 400 and 0.4-0.8% of redispersible rubber powder.
As an improvement, the activity excitant is AOS powder.
After adopting the structure, the invention has the following advantages: the lightweight aggregate is adopted, a 10-80mm thick layer can be poured, the vitrified micro bubbles of the sound insulation and heat insulation material are added, the vitrified micro bubbles have suspension performance in mortar, the phenomena of sand sedimentation, segregation and the like can not be generated when the mortar is poured for a certain thickness, the vitrified micro bubbles can be uniformly dispersed in the mortar body and attached with sand for suspension, so the sedimentation is not generated, and the problem of sedimentation of self-leveling sand can be effectively solved; the density of the mortar is 1000/M3, is 80 percent of that of the traditional self-leveling mortar, has small density and light weight, and can reduce the dead weight of a high-rise building; the noise generated by impact is consumed through the properties (such as damping) and the structure of the vitrified micro bubbles, and the vitrified micro bubbles have the functions of sound insulation and heat preservation; the compressive strength is 5.5mpa in 24 hours, and normal construction can be guaranteed in the next day after irrigation.
