Abstract
The invention provides a waterproof sound-insulation coating. The waterproof sound-insulation coating contains modified basalt fibers and a nano-scale inorganic substance with a porous structure at the same time. The modified basalt fibers can be uniformly distributed after the coating forms a film, so that transmitted sound wave energy is reduced, and a sound insulation effect is achieved. The nano-scale inorganic matter has a large number of micropores, so that the nano-scale inorganic matter has good adsorption performance. A sound absorption material and a sound insulation material are overlaid, a good sound insulation effect is generated, and the impact sound pressure level improvement amount can be increased to 20-27 db and is far higher than that of an existing product. Meanwhile, the product has better tensile strength, elongation at break and impermeability, and is a waterproof coating with better performance and higher flexibility.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to a waterproof and sound-insulating coating and a preparation method thereof. Background technique [0002] With the development of modern information and networks, and the increase in the number of people working from home, noise pollution is becoming more and more prominent. Experimental data proves that people will feel irritable and endanger human health when the environment exceeds a certain decibel. At present, the distance between buildings in the city is relatively short, which will affect people's lives in the long run. Noise pollution, water pollution, air pollution, and solid waste pollution are listed as the four major environmental hazards in today's society. Countries all over the world pay more attention to environmental protection, while my country has taken environmental protection as a basic national policy. [0003] The development of sound insulatio...
