Plate for noise barrier and manufacturing method thereof

Abstract

The invention provides a plate for noise barrier and a manufacturing method thereof. The plate for noise barrier comprises an aluminium honeycomb layer and a foamed aluminium layer, wherein the aluminium honeycomb layer is a hexagonal honeycombed lamella made of a thin aluminum sheet; the foamed aluminium layer is a foamed aluminium sheet which has sound-absorbing function and is provided with a plurality of air holes; the aluminium honeycomb layer is compounded with the foamed aluminium layer by an adhesive film so as to form the plate for noise barrier; moreover, the plate for noise barrier is further provided with a sound-proof material layer; and in the plate for noise barrier, one side of the aluminium honeycomb layer is compounded with the foamed aluminium layer through the adhesive film, while the other side is compounded with the sound-proof material layer through the adhesive film. The plate for noise barrier has a great noise reduction effect on a wide range of frequencies of noises, particularly the low frequency noise below 500 Hertz. The plate has the advantages of easy construction and maintenance, low cost and no dust, can be recycled, and does not burn or produce toxic gases in case of fire.

AI Technical Summary

Benefits of technology

This patented product has several technical benefits: it reduces sounds from different frequency ranges by effectively absorbing them while still maintaining good strength for durability over time without generating harmful chemicals or causing damage during use; making building materials easier to work on safely at all times due to their lightweight design that doesn't generate any smoke when burning outdoors even if they are accidentally dropped into water.

Problems solved by technology

Technological Problem: Current methods aimed at reducing noise involve adding layers of different types of sound shield systems that can absorb sounds without causing discomfort or damage themselves. These solutions often result in increased manufacturing time, waste, and potential negative impacts over longer periods of usage. Additionally, current methods involving filling up these sound screens may lead to decreased performance caused by lower levels of loudness.
