Magnesium sulfate and red mud sound insulation and noise reduction decorative plate and preparing method thereof

Abstract

The invention provides a magnesium sulfate and red mud sound insulation and noise reduction decorative plate and a preparing method thereof. The magnesium sulfate and red mud sound insulation and noise reduction decorative plate comprises a bottom mortar layer, a non-woven fabric layer, three glass fiber fabric layers, a middle material layer, three glass fiber fabric layers and a sanded layer from bottom to top in sequence, and the details are shown in the drawings of the description. The bottom mortar layer is prepared from any one of light calcined magnesia, magnesium sulfate heptahydrate, water, talcum powder, latex powder, red mud, a modifying agent, iron oxide red, iron oxide green, iron oxide blue and carbon black. The middle material layer is prepared from any one of light calcined magnesia, magnesium sulfate heptahydrate, water, wood dust, red mud, other filler, a modifying agent, iron oxide red, iron oxide green, iron oxide blue and carbon black. The sanded layer is prepared from light calcined magnesia, magnesium sulfate heptahydrate, water, wood meal, a defoaming agent, a modifying agent, iron oxide red, iron oxide green, iron oxide blue and carbon black.

Description

technical field [0001] The invention relates to a building material, in particular to a magnesium sulfate red mud decorative board capable of sound insulation and noise reduction, and a preparation method thereof. Background technique [0002] Noise belongs to a large category of environmental pollution, and has been listed as the three major environmental pollution sources together with air pollution and water pollution. With the development of modern industry, construction industry, transportation industry, etc., the problem of noise pollution has become increasingly prominent, which is one of the main factors affecting people's quality of life and endangering human health. Looking at the work done at home and abroad to reduce environmental noise pollution, it is mainly in two aspects: one is to control and treat noise sources, that is, to transform noisy equipment into low-noise or even silent equipment; Noise reduction on the sound wave propagation path is mainly to dev...

AI Technical Summary

Problems solved by technology

The traditional sound insulation wall mainly relies on the density and thickness of the wall material to control the noise, which not only has a single form of noise reduction, but also is bulky and thick and takes up a lot of space.
