Problems solved by technology

[0003] However, traditional sound-absorbing materials have limitations: although organic materials have a wide sound-absorbing frequency band and good effect, they have poor anti-corrosion and fire-proof performance and are not suitable for use in humid environments; although inorganic materials have good flame-retardant, sound-absorbing, and non-aging advantages, but Soft, unsuitable for storage and transportation, easy to break, causing dust to pollute the environment

Abstract

The invention provides a volcanic cinder lightweight porous sound-absorbing wallboard and a preparation method thereof. Carbon nanotubes are taken as the carrier. Nano titanium dioxide and nano zinc oxide are taken as the photocatalytic elements. Rare earth elements (lanthanum and europium) and graphene are reactants of catalytic photochemical reactions. The quantum lead effect of carbon nanotubesis utilized to effectively enhance the photoelectron capturing performance of rare earth elements; graphene is used to catalyze the photocatalytic degradation of harmful gas; volcanic cinder has excellent micro-activity and a good adsorbing performance and can absorb and isolate sound and prevent fire; the provided sound-absorbing wallboard can effectively absorb photocatalysts, is capable of effectively absorbing and isolating sound waves, and can modulate indoor temperature and humidity.

Description

technical field [0001] The invention discloses a volcanic slag lightweight porous sound-absorbing wallboard, relates to a composition material and a preparation method of a volcanic slag lightweight porous sound-absorbing wallboard, and belongs to the technical field of building materials. technical background [0002] Noise has a serious impact on people's health and work. As an effective means of noise reduction, sound-absorbing materials are widely used, including road tunnels, gymnasiums, cinemas, converter stations, school classrooms, and civil buildings. Wait. At present, organic sound-absorbing materials and inorganic porous sound-absorbing materials are mainly used widely, such as foam glass, foam ceramics, and composite sound-absorbing materials. [0003] However, traditional sound-absorbing materials have limitations: although organic materials have a wide sound-absorbing frequency band and good effect, they have poor anti-corrosion and fire-proof performance and ...
