Problems solved by technology

However, traditional sound-absorbing coatings usually only have sound-absorbing and noise-proof effects, and the noise-proof effect between floors is poor, noise pollution will still occur, and the sound insulation effect is not good
Moreover, the main raw materials used in traditional sound-absorbing coatings and mineral wool boards contain high levels of harmful volatile substances and heavy metals, which is not conducive to environmental protection, and is likely to cause harm to the human body when used.

Abstract

The invention discloses a sound insulation and shock absorption coating and a preparation method thereof. The sound insulation and shock absorption coating is prepared from, according to percentage byweight, 5%-7% of VAE emulsion, 5%-7% of floating beads, 38%-45% of stone-free mineral wool, 3%-5% of mica powder, 35%-45% of water and 1% of auxiliary materials. The coating has good sound insulationand noise reduction functions and also has good shock absorption and noise reduction effects and achieves dual noise reduction and can effectively improve the noise pollution prevention function of buildings. Moreover, the coating has good fireproof performance, high flame retardance, good wear resistance and insulating property, low content of harmful volatile substances and heavy metals and isgreen and environment-friendly. The preparation method is mild in condition and low in energy consumption and can be used for effectively preparing and producing the sound insulation and shock absorption coating on a large scale.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a sound-insulating and shock-absorbing coating and a preparation method thereof. Background technique [0002] With the development of society, the noise pollution in the city is also increasing, and it is getting bigger and bigger. Especially in commercial housing, due to the low density between buildings and the close connection between floors, often small sounds or vibrations will become serious noise pollution. Noise pollution is likely to cause trouble and harm to people's health and daily life, and is not conducive to people's physical and mental health. People pay more and more attention to the harm of noise pollution to people's health and daily life. How to provide people with a quiet and comfortable living environment through the sound insulation of building materials, the position of the sound insulation function of buildings in many building functions ...
