Abstract

The invention provides a non-combustible air purification acoustic absorption composite material as well as a preparation method thereof. The preparation method comprises the following steps: (1) impregnating, carrying out roll compacting on and drying an activated carbon fiber felt so as to obtain an impregnation treatment felt; (2) carrying out waterproof treatment on the single surface of the impregnation treatment felt, drying, and spraying glue on the surface so as to obtain a glue spraying treatment felt; (3) compounding the glue spraying treatment felt directly along the glue spraying surface or compounding by inserting a layer of barbed wire into the glue spraying treatment felt, applying certain pressure, drying and forming, or carrying out quilting enhancement on the impregnation treatment felt directly by adopting a quilting machine so as to obtain the non-combustible air purification acoustic absorption composite material. The acoustic absorption composite material obtained by the invention has the characteristics of no smoke or naked flame in catching fire, flexible hand feel, good acoustic absorption, indoor air purification, no falling fiber in knocking and the like, also can be combined with other decoration materials to prepare acoustic absorption flame-retardant decoration materials, and is especially suitable for public places with condense people and high fire fighting requirements, such as KTV, bars, theaters and auditoriums.

Description

technical field [0001] The invention belongs to the field of new materials, and mainly relates to a non-combustible air-purifying and sound-absorbing composite material and a preparation method thereof. Background technique [0002] There is serious noise pollution in public entertainment places such as bars and KTV, and it is necessary to choose suitable sound-absorbing materials during the decoration process. Indoor sound-absorbing decorative materials such as polyurethane and PET non-woven fabrics have serious fire safety hazards, and the fire department has strictly prohibited the use of these sound-absorbing materials. Due to the airtight space of places such as KTVs and bars, people not only need materials that reduce noise and meet fire protection requirements, but also hope that these materials can have good air purification functions. Although activated carbon particles are usually used in the market to achieve the adsorption function, the activated carbon has a sh...
