Light sound insulation plastic plate

Abstract

The invention discloses a light sound insulation plastic plate. The light sound insulation plastic plate comprises a substrate and a cover plate above the substrate, wherein a soft sound insulation material is arranged between the substrate and the cover plate; the substrate and the cover plate are adhered together through a strong adhesive; the surface of the cover plate is provided with a layer of a brightener; the substrate is a polypropylene plastic plate; the cover plate is a polyvinyl chloride plastic plate; the soft sound insulation material is glass wool; the strong adhesive is an unsaturated polyester resin; and the brightener is modified amide wax. The polypropylene plastic plate and the polyvinyl chloride plastic plate are adopted to form the light sound insulation plate, so the light sound insulation plastic plate has the advantages of low cost, strong impact strength, difficult damage, stable connection through the strong adhesive, and no shedding; the middle is formed by the soft sound insulation material, so the light sound insulation plastic plate has the advantages of light mass, convenient carrying, and extremely-good sound insulation effect; and the surface of the cover plate is coated with the layer of the brightener, so the apparent texture of the light sound insulation plastic plate is increased.

Description

technical field [0001] The invention relates to a plastic product, in particular to a light-duty sound-insulating plastic board. Background technique [0002] At present, most of the sound insulation boards are made of sound insulation materials in a hollow body composed of panels, backboards, etc. Since the front panel, back panel and side panel are all made independently, rivets are used to connect the panel, back panel and side panel. Such a rivet connection method is not stable enough, and there will be seams at the joints of the panels. The sealing effect is not good, and at the same time, it is easy to cause damage to the board and affect the sound insulation effect. [0003] In the prior art, a sound insulation board includes a metal end frame, a metal bottom plate, and a porous sound-absorbing plate. There are several partitions between the metal end frames. The space is filled with sound-insulating materials, and the partitions and metal end frames are fixedly con...

AI Technical Summary

Problems solved by technology

The problem is that it is difficult to install the metal plate, and the sound insulation board will vibrate. In addition, the price of the metal sound insulation board is relatively expensive and cannot be popularized.
