Description

Technical Field

[0001] The invention relates to the technical field of building construction materials, and in particular to a waterproof and sound-insulating coating applied to building floors. Background Art

[0002] The sound insulation coating is made of high-performance damping and shock-absorbing materials, inorganic mineral fibers, hollow ceramic microbeads, Portland cement and other materials as well as related water-based additives. It is a pure water-based product. Its total VOC and benzene content is far lower than the national standard. The test results of authoritative testing agencies show that the content is even more than ten times lower than the national standard. In addition, the sound insulation coating has excellent waterproof properties. After the finished sample is soaked in water for 15 consecutive days, the surface does not fall off, delaminate, bubble or hollow, and the performance is stable.

[0003] Waterproof sound insulation coatings have good compatibility with many composite substrates and can be widely used in various construction scenarios to provide efficient sound insulation and thermal insulation effects for buildings. Whether it is a residential building, office building or commercial place, waterproof sound insulation coatings can provide excellent sound insulation effects for buildings and create a more quiet and comfortable environment.

[0004] Current sound insulation coatings are generally single-component materials, and the gelling material is acrylic emulsion. It relies on organic particles to gradually cross-link, polymerize, and form a film during the drying process. The film has general water resistance and low strength. It is easy to be damaged, hollow, and peel during subsequent construction, affecting the final sound insulation effect. Summary of the invention

[0005] In order to overcome the above-mentioned shortcomings, the purpose of the present invention is to provide a waterproof and sound-insulating coating for use on building floors. The water resistance and waterproofing performance of the coating are improved by the interaction of organic and inorganic particles to form a film. The coating can resist blisters for a long time and will not peel or hollow. At the same time, the drying and hardening speed and strength of the coating are increased, and the coating is not easily damaged during cross-construction and subsequent construction.
