Abstract

The invention discloses a sound-absorbing coating material, wherein every 100 parts by mass of coating contains 5-50 parts by mass of sound-absorbing function materials, 0.1-35 parts by mass of flame retardant materials, 10-40 parts by mass of binding materials, and the balance of an inorganic filling, an assistant and water in a common coating. The sound-absorbing function materials are selected from one or composite of some of materials such as slag fibers, mineral fibers, glass fibers and wood fibers, with fiber structures, and the sound-absorbing function materials are subjected to waterproof modification treatment. According to the invention, NRC (Noise Reduction Coefficient) of the coating material is tested to be more than 0.4 by using a standing wave tube method, and the sound-absorbing coating material has a good sound-absorbing denoising performance, excellent flame resistance and low heat conductivity coefficient, can be used for reducing the energy consumption of a building, is an environmental-friendly functional sound-absorbing coating material integrated with functions of sound absorption, flame resistance and decoration, and can be used on the surface of the building.

Description

technical field

[0001] The invention belongs to the field of building materials and relates to a novel sound-absorbing coating material, which can be widely used in building indoor environments. The material not only has excellent sound absorption performance, but also has good fireproof and waterproof performance, and has good decorative performance. Background technique

[0002] Together with air pollution and water pollution, noise pollution is called the three major pollutions in the world today. Especially with the rapid development of industry in recent years, the rapid development of the automobile industry, and the improvement of people's living standards, these factors have brought huge noise pollution to the living environment. Noise pollution will not only affect the safe performance of mechanical, electronic and other equipment, but also bring serious harm to human health.

[0003] People pay more and more attention to the harm of noise pollution to people's he...
