Problems solved by technology

However, the currently published patented technology has the following problems: NRC is not high, and the mute effect is limited; the flame retardancy of the product is not good; the adhesive emulsion emits irritating and harmful gases during the drying process, etc.
Patent CN1425720A (Application No. 03118445.6) discloses a sound-absorbing and environmentally friendly coating. The coating uses fly ash floating beads as lightweight aggregates to improve the quiet effect. However, due to the closed and impermeable pores of the fly ash floating beads, the coating Layer muting is not ideal
Patent CN1429869A (Application No. 01145015.0) discloses a special flashing and sound-absorbing coating for a concert hall, which adds light perlite and foamed polystyrene particles to produce a certain sound-absorbing and mute effect; but the foamed polystyrene particles will release Toxic gas, so the coating has potential safety hazards; and the invention does not screen the light perlite selected, and the sound absorption effect is not ideal

Abstract

The invention relates to mute environment-friendly paint and a preparation method thereof. The mute environment-friendly paint consists of filler, an odor-eliminating latex, an assistant, pigment, a flame retardant and water, wherein the filler comprises a wood fiber, diatomite, expanded perlite and hollow glass microspheres; the expanded perlite is open pore expanded perlite with 14-120 meshes; and the average grain diameter of the odor-eliminating latex is 0.15-0.5mu m. The preparation method of the mute environment-friendly paint comprises three steps of premixing, dispersing and grinding and adjusting paint. The prepared mute environment-friendly paint has the advantages of favorable mute effect, safety, environmental protection, capability of adjusting the indoor air temperature, simple and convenient construction, favorable decorative effect and the like as well as favorable market prospect.

Description

Technical field [0001] The invention relates to an architectural paint and a preparation method thereof, in particular to a silent environmental protection paint and a preparation method thereof. Background technique [0002] The noise pollution in modern society, especially the harm of indoor noise pollution to health and daily life, is gradually being valued by people. Therefore, many modern buildings need to consider their internal mute effect when designing. Silent materials can not only improve the indoor sound quality environment, but also play a very important role in noise control. There are many types of traditional building mute materials. The common ones are gypsum decorative sound-absorbing panels, glass wool decorative sound-absorbing panels, rock (mineral) wool decorative sound-absorbing panels, perlite decorative sound-absorbing panels, and polystyrene foam decorative sound-absorbing panels. Acoustic panels, metal decorative sound-absorbing panels, micro-perforate...
