Problems solved by technology

[0005] Chinese invention patent ZL201110107485.0 "A Sound-absorbing Coating and Its Preparation Method" involves a two-component coating, which is a bit complicated to construct and use; the main sound-absorbing functional filler of component A, sepiolite, comes from serpentine alteration. And serpentine is the main component of asbestos, so it is difficult to completely separate asbestos, which poses a certain environmental threat. At the same time, sepiolite has strong water absorption. Under the blocking of film-forming substances, the slow release of water affects the drying of paint. speed; the use of polystyrene foam particles in component B will release harmful gases when heated or burned, and there are also environmental threats

Abstract

The invention discloses a nano modified water-base multifunctional sound-absorbing paint and a preparation method thereof. The paint is composed of the following components in parts by weight: 28-38 parts of emulsion, 2-10 parts of pigment, 30-45 parts of filler, 15-25 parts of water, 4-8 parts of flame retardant and 2.25-5.43 parts of assistant. By optimizing the paint system structure, the polymer and filler are selected, modified and proportioned to ensure the basic mechanical properties and sound-absorbing function, and the paint has high-value service properties, such as thermal insulation, moisture resistance, fire resistance, aging resistance, fouling resistance, sterilization, air purification and the like, and is especially suitable for rooms and other occasions with higher environmental requirements.

Description

technical field [0001] The invention relates to a building coating and a preparation method thereof, in particular to a multifunctional sound-absorbing coating and a preparation method thereof. Background technique [0002] In many building spaces without surface treatment, the multiple reflections of sound on the rigid surface of the structure will cause mutual interference of sound waves in the internal space, increasing the sound pressure level of indoor noise, especially in large building spaces, the impact of sound reflection will cause indoor reverberation If it is too large, it will affect normal language communication and listening enjoyment. Therefore, in many occasions, such as KTV, bars, concert halls, theaters, gymnasiums, recording and broadcasting rooms, conference rooms, lecture halls, multi-functional auditoriums, home audio-visual rooms, etc., it is necessary to perform sound-absorbing treatment on the surface of the walls of the indoor space. Reverberation...
