Waterborne sound insulation and thermal insulation coating and preparation method and construction method thereof

Abstract

The invention provides a waterborne sound insulation and thermal insulation coating, and a preparation method and a construction method thereof and belongs to the field of coatings. The waterborne sound insulation and thermal insulation coating is prepared from the following raw materials in percentage by weight: 22.0-43.0 percent of a waterborne synthetic resin emulsion, 24.0-45.0 percent of a modified sound insulation material, 6.0-17.0 percent of a thermal insulation material, 0.6-2.0 percent of a wetting agent, 0.6-2.0 percent of a dispersing agent, 0.2-1.2 percent of a pH regulator, 3.0-17.0 percent of pigments and fillers, 1.4-5.0 percent of a thickening agent, 0.6-2.0 percent of a de-foaming agent, 1.0-3.0 percent of an anti-freezing agent, 0.3-1.3 percent of a bactericide, 1.0-3.0percent of a film forming aid and 1.5-11.0 percent of deionized water. The modified sound insulation material added in the waterborne sound insulation and thermal insulation coating has the characteristics that the damping coefficient is high, and absorbed energy can better absorb sound energy. The waterborne sound insulation and thermal insulation coating provided by the invention has the characteristics of being good in sound insulation and thermal insulation effects, low in odor, waterborne and environmentally friendly, simple to construct and simple and convenient for later maintenance andservice.

Description

technical field [0001] The invention relates to a water-based sound-insulating and heat-insulating coating, which belongs to the field of coatings. Background technique [0002] With the rapid development of our country and the rapid innovation of science and technology, sound insulation materials for building houses were born during this period. It is particularly important to isolate noise, heat preservation and environmental protection, and create a quiet and comfortable living environment. So how to block noise and how to reduce heat loss has become a very hot topic at the moment. At present, there are three most commonly used methods: internal paste prefabricated insulation board, internal paste reinforced plaster polystyrene board, internal application of rubber powder and benzene particle insulation slurry, etc. However, most of these materials are some macromolecular organic materials, which are flammable and release a large amount of toxic and harmful substances wh...

Problems solved by technology

Moreover, most of these materials are relatively complicated in construction and high in maintenance costs.

It can be seen that the traditional sound insulation materials can no longer meet people's needs.
