Sound barrier and absorbent particles insulation panel

The present invention discloses a stable acoustic performance, sound barrier particles mainly made of particle board and its absorbent panel insulation, sound absorption absorption absorption fine particles the surface layer of the insulation panel using surface is covered by skeleton and fine particle filler having a smaller angular coefficient of the adhesive layer bonded to each other with the particle board microporosity, particle board insulation layer absorbent surface acoustic insulation panel is employed by the skeleton particles, filled particles, a binder and a coupling agent bonded close to each other into a compact plate, the inner panel sound absorption body resonance sound absorbing surface layer interaction chamber. The sound barrier comprising uprights and particulate absorbent insulation panel fixed in the top of each other between two adjacent columns or more, adhesion between the end face of the suction insulation panel is provided with a convex engaging end surfaces are engaged sealing cushion. Its stable acoustic performance, weather resistance, low production cost, easy sound barrier made of different colors, easy to clean, especially for noise control high-speed railway and highway.
