Novel composite wallboard for thermal insulation and sound absorption

Abstract

The invention brings forward a novel composite wallboard for thermal insulation and sound absorption. The novel composite wallboard comprises a surface layer, a base layer, a sound-absorbing layer and a thermal-insulation layer. The thermal-insulation layer is arranged between the sound-absorbing layer and the surface layer. The surface layer is a modified magnesite board layer. The base layer is a PE wood-plastic composite layer. The sound-absorbing layer is a honeycomb core plate. The thermal-insulation layer is an ERS foam board. The wallboard of the invention has a reasonable structure, is light and environment friendly, has excellent heat insulation effect, has good sound insulation and sound absorption functions. by the use of the wallboard, comfort degree of a dwelling environment is guaranteed. Through action of expanded graphite particles, the influence of lots of outdoor electromagnetic radiation on the dwelling environment can be reduced. Thus, human health is guaranteed, and quality of human dwelling environment is further raised.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a novel composite wallboard for heat preservation and sound absorption. Background technique [0002] As a material for decorative walls, wall panels are widely used in decoration. Among the existing products on the market, the more common ones are: plasterboard, aluminum alloy gusset or wooden wallboard. These products generally have such defects: no heat preservation, no heat insulation, no waterproof and moisture-proof, no sound insulation, easy to mold and corrode, and the installation needs to be installed with a chassis or the wall needs to be treated, and paint is required. It cannot be eliminated for a long time, which is time-consuming and laborious, and it is not environmentally friendly. Moreover, with the acceleration of the urbanization process, more and more people live in commercial housing and improve their living conditions. However, the wall structu...

These products generally have such defects: no heat preservation, no heat insulation, no waterproof and moisture-proof, no sound insulation, easy to mold and corrode, and the installation needs to be installed with a chassis or the wall needs to be treated, and paint is required. It cannot be eliminated for a long time, it is time-consuming and laborious, and it is not environmentally friendly

Moreover, with the acceleration of the urbanization process, more and more people live in commercial housing and improve their living conditions. However, the wall structure of the current building is single, and the sound from the next door is easy to spread and diffuse in their own room, affecting live and rest
