Problems solved by technology

However, there are still some problems in the process of using wooden floors. For example, the impact noise of wooden floors is sharper, and the sound insulation requirements for the ground are higher. Moreover, wooden floors will continuously release formaldehyde, which has a long release cycle and endangers people's health.

Abstract

The invention provides a water-based damping coating. Compared with the prior art, the water-based damping coating provided by the invention comprises the microcapsule formaldehyde remover, the microcapsule adopts amino acid, tea polyphenol, an adsorbent and the like as a core material, has excellent formaldehyde removal performance and can remove formaldehyde for a long time, and a beta-cyclodextrin cross-linked polymer is adopted as a wall material and has a hollow cylindrical structure with two open ends, not only can formaldehyde molecules be effectively captured, but also a very excellent sound absorption function is achieved, so that the microcapsule formaldehyde remover has dual functions of formaldehyde removal and sound absorption; the microcapsule formaldehyde remover and other components of the coating cooperate with each other, so that the water-based damping coating has excellent sound insulation performance and long-acting formaldehyde removal performance at the same time, and also has relatively high low-temperature stability and water resistance.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a microcapsule formaldehyde remover, a preparation method thereof, and a water-based damping coating. Background technique [0002] The indoor environment of civil buildings is often disturbed by various noises. Among them, the interference from the upper floor, especially the interference from the impact sound of the floor, is common in many buildings, especially in residential buildings. GB 50118-2010 "Code for Design of Sound Insulation of Civil Buildings" has made detailed regulations on the impact sound insulation performance of residential floors. 65dB. The thickness of rough or dry floor tiles in residential buildings in my country is generally 100-150 mm, which cannot meet the impact sound insulation performance of floor slabs. At present, the main way to improve the sound insulation performance of floors is damping and vibration reduction, that is, paintin...
