Abstract

The invention discloses a sound insulation composite aluminum plate for a curtain wall and a preparation method thereof. The composite aluminum plate comprises an upper aluminum plate,a core layer, and a lower aluminum plate from top to bottom; the upper aluminum plate and the lower aluminum plate are connected around the core layer in a closed manner; the upper end and the lower end of the core layer are bonded through macromolecule bonding films, a layer of PET composite film is laid on the outer layer of the upper aluminum plate; the PET composite film is further coated with a PVDF fluorocarbon layer, the core layer comprises an upper nonmetal composite layer, a honeycomb layer and a lower nonmetal composite layer from top to bottom, the honeycomb layer is fixedly connected with the upper aluminum plate and the lower aluminum plate, and the aluminum plate has the advantages that the sound insulation effect is excellent, and the service life of the totally-closed aluminum plate is longer.

Description

technical field [0001] The invention relates to the technical field of composite panels, in particular to a sound-insulating composite aluminum panel for curtain walls and a preparation method thereof. Background technique [0002] As a new type of decorative material, aluminum-plastic composite panels were introduced to China from Germany in the late 1980s and early 1990s. They have become popular with their economy, variety of optional colors, convenient construction methods, and excellent processing performance. , excellent fire resistance and noble quality, it is quickly favored by people. [0003] The unique performance of the aluminum-plastic composite panel itself determines its wide range of uses: it can be used for building exterior walls, curtain wall panels, renovation of old buildings, interior wall and ceiling decoration, advertising signs, display stands, purification and dust prevention Engineering belongs to a new type of building decoration material, but th...
