Abstract:
The present invention relates to a sound proof panel for blocking traffic noise and a method for manufacturing the same. More specifically, the purpose of the present invention is to provide a traffic noise protecting panel and a method for manufacturing the same capable of remarkably reducing installation costs because of the weigh lightening of the panel, improving durability against ultraviolet rays, and maintaining visibility and preventing contaminant from being attached to a surface at the same time. To achieve the purpose, the traffic noise protecting panel comprises: a plurality of outer surface layers which have at least one of an air layer and a vacuum layer to be sealed therein; a check valve member which is provided on a side of the outer surface layer and allows the communication from the outside to the inside and prevents the communication from the inside to the outside; and a sealing means for sealing an edge of the outer surface layer. The method for manufacturing the traffic noise protecting panel includes: a step of forming a plurality of outer surface layers using polyethylene (PE) and ethylene tetrafluoroethytlene (ETFE) to have at least one space therein; a step of sealing the edge of the outer surface layers; and a step of injecting air into the inner space of the sealed outer surface layers or making vacuum condition in the inner space of the sealed outer surface layers.
