Embodiment Construction

[0021] Example figure 1 As shown, the sound barrier board prepared by solid waste in the present invention includes a perforated panel 1, a first partition 2, a perforated bottom plate 3, a fixed net 4, a second partition 5 and a sound insulation board 7 connected in sequence. The perforated panel 1, the first dividing plate 2, the perforated bottom plate 3, the second dividing plate 5 and the sound insulation plate 7 are made of the following raw materials in parts by weight: polyvinyl chloride resin 50-80%, solid waste 10- 40%, processing aid 1-8%, stabilizer 2-6%, foaming agent 0-3%, lubricant 1-10%, and it is made by one-shot molding process of crust micro-foaming melt extrusion. This molding process makes the core layer of the product present a dense and uniform cell structure on the microscopic level, which not only achieves a certain sound-absorbing effect, but also meets its service strength, aging resistance, and corrosion resistance, and is easy to process and instal...

Abstract

The invention discloses a sound barrier plate prepared by using solid wastes. The sound barrier plate is formed by successively connecting a perforated panel, a first partition plate, a perforated bottom plate, a fixed net, a second partition plate and a soundproof plate. The perforated panel, the first partition plate, the perforated bottom plate, the second partition plate and the soundproof plate are prepared from the following raw materials in percentages by weight: 50-80% of polyvinyl chloride resin, 10-40% of solid wastes, 1-8% of a processing aid, 2-6% of a stabilizer, 0-3% of a foaming agent and 1-10% of a lubricant. The perforated panel, the first partition plate, the perforated bottom plate, the second partition plate and the soundproof plate are prepared through a crust micro-foaming melt extrusion primary forming process. The sound barrier plate disclosed by the invention overcomes the defects of a conventional sound barrier plate, the weather resistance is improved and the service life is prolonged, and the manufacturing cost is reduced; the sound barrier plate has the advantages of being excellent in sound-absorbing and isolating properties, high in mechanical strength, smooth in surface, light in weight, convenient to mount and the like, and meanwhile, the resource utilization of the solid wastes is improved, and the environmental protection is facilitated.

Description

technical field [0001] The invention relates to the field of noise control of expressways, railways and light rails in environmental protection, in particular to a sound barrier plate prepared by using solid waste. Background technique [0002] With the rapid development of my country's infrastructure construction, a large number of highways, high-speed railways, and urban light rails have been built, which bring convenience to people. At the same time, the problem of traffic noise pollution is becoming more and more serious. Residents along the line are deeply affected, disturbing residents' normal work, study and life. The control of noise pollution has become an urgent social problem. At the same time, with the rapid advancement of industrialization and urbanization, more and more solid wastes are generated in production and life, and the environmental problems caused by solid wastes are also prominent. How to deal with them scientifically and rationally The reduction of...
