Sound-absorbing and noise-reducing putty paste and preparation method thereof

Abstract

The invention relates to sound-absorbing and noise-reducing putty paste and a preparation method thereof, and belongs to the technical field of building materials. The putty paste is prepared from the following raw material components in percentage by mass: 8 to 15 percent of silica sol, 0.5 to 0.8 percent of dispersing agent, 0.2 to 0.4 percent of defoaming agent, 15 to 20 percent of silica gel powder, 8 to 12 percent of wood fiber powder, 20 to 34 percent of filler, 0.5 to 1.0 percent of silane coupling agent, 10 to 25 percent of synthetic resin emulsion, 0.3 to 1.4 percent of thickening agent and the balance of water. The putty paste further comprises 0.5 to 1.0 percent of a stabilizing agent, so that the material with the large specific surface area has good adsorption resistance and operation stability. The prepared putty paste is safe, environmentally friendly, convenient to construct, good in compatibility with indoor building materials and good in sound absorption and noise reduction effect.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a sound-absorbing and noise-reducing putty paste and a preparation method thereof. Background technique [0002] At present, noise pollution, water pollution and air pollution have become the three major environmental pollution in the world today, endangering human hearing, aging of buildings, use of confidential equipment and so on. In order to pursue the quality of life, the noise reduction problem in buildings has also been paid more and more attention by people. The currently used noise reduction materials are basically divided into sound insulation materials, sound absorption materials and damping materials: sound insulation materials need to block and weaken the incident sound energy, generally some high-quality and high-density materials, such as concrete walls, iron plates, high-density Plates, etc.; sound-absorbing materials use the meandering channels connec...

AI Technical Summary

Problems solved by technology

Although there are walls and glass in residential houses that can reduce noise to a certain extent, especially the effect of adjacent floors and adjacent rooms in the building is not always satisfactory.

In this situation, when using noise-reducing coatings in other fields as a compensation method, there are often problems such as insufficient safety, environmental protection, lack of pertinence, poor matching with building materials, and low cost performance.
