A damping and noise-reducing composite material for air purification

Abstract

The invention discloses a damping noise-reducing compound material for purifying air. The compound material comprises a sound-absorbing layer, a functional layer, a butyl rubber layer and a release paper which are successively pasted from top to bottom, wherein the functional layer contains chlorine dioxide and can continuously release chlorine dioxide; a slow-release active agent is sprayed on the surface of the functional layer; the functional layer and the butyl rubber layer are extruded and adhered in the manner of double-layer co-extrusion; the functional layer is composed of the following components by weight part: 90-110 parts of butyl rubber layer, 55-65 parts of fillers, 75-85 parts of tackifier, 1-20 parts of chlorine dioxide slow releasing agent and 1-20 parts of activated fillers. The damping noise-reducing compound material for purifying air is convenient to construct, has the characteristics of damping limitation, high noise-absorbing property, capability of continuously purifying air, and the like, is non-toxic and environment-friendly and has obvious effect of reducing noise and purifying air.

Description

technical field [0001] The invention relates to a damping and noise-reducing composite material with the function of purifying air. Background technique [0002] In recent years, in living environments such as automobiles and indoors, formaldehyde and organic volatiles are seriously polluted and affect human health, which has attracted widespread attention. Purifying air is a common concern of people. The existing main methods of air purification are conventional activated carbon exposure adsorption and the use of air purifiers. As an internationally recognized high-efficiency antiseptic and preservative, chlorine dioxide has been widely used in the food industry. At the same time, chlorine dioxide can also be used in pulp fabric bleaching, wastewater treatment and drinking water disinfection and sterilization. Chlorine dioxide in a suitable concentration range can react with organic volatiles such as formaldehyde in the air, sterilize, remove odor, and is harmless to the h...

AI Technical Summary

Problems solved by technology

None of the above solutions can effectively solve the problem of slow release of chlorine dioxide, and it is easy to have the problem of excessive chlorine dioxide release, causing secondary pollution

At the same time, self-adhesive non-vulcanized damping rubber composite materials are often used for shock and noise reduction in automobiles, indoors, KTV rooms, etc., usually only have the function of shock and noise reduction, and the function is relatively single
