Aluminum honeycomb ceiling board with micro-perforated sandwich layer

Abstract

The invention relates to an aluminum honeycomb ceiling board with a micro-perforated sandwich layer. The aluminum honeycomb ceiling board comprises an upper aluminum plate, a lower aluminum plate and the micro-perforated sandwich layer, wherein the micro-perforated sandwich layer is bonded between the upper aluminum plate and the lower aluminum plate, a plurality of breakable dotted line grooves are evenly formed in the micro-perforated sandwich layer in a penetrating mode, all the breakable dotted line grooves are connected end to end to form a closed ring, and a to-be-pushed sandwich block which is connected with the micro-perforated sandwich layer through a plurality of ribs is formed in the closed ring. According to the aluminum honeycomb ceiling board, protruding aluminum plates and grooves on the upper aluminum plate and the lower aluminum plate correspond to the to-be-pushed sandwich block on the micro-perforated sandwich layer, the protruding aluminum plates, the grooves and the sandwich block can be nested through pressing operation, sound absorption structures extend into the aluminum plates, the sound absorption area is increased, the sound absorption efficiency is improved, and the protruding aluminum plates extend into the micro-perforated sandwich layer and is used for supporting the micro-perforated sandwich layer, so that the micro-perforated sandwich layer is prevented from deforming and stripping, and the whole ceiling board has the advantages of high strength and good sound absorption effect.

Description

technical field [0001] The invention belongs to the technical field of interior decoration materials, and in particular relates to an aluminum honeycomb ceiling board with a micro-perforated sandwich layer. Background technique [0002] At present, aluminum plate ceilings have been widely used. Generally, folded edges are set on the back of the decorative surface of the aluminum plate, which is used to clamp the hooked aluminum plate on the top for sliding assembly. , and in order to meet functional requirements such as sound absorption and noise reduction, an interlayer with sound absorption or other functions is generally provided inside the aluminum plate. [0003] The interlayer in the existing aluminum plate is divided into two types: [0004] One is directly bonded and fixed between two aluminum plates, the edges are exposed to the air, the adhesive layer is easily peeled off by the environment, and in order to increase the stability of the connection, the general met...

Problems solved by technology

[0004] One is directly bonded and fixed between two aluminum plates, the edges are exposed to the air, the adhesive layer is easily peeled off by the environment, and in order to increase the stability of the connection, the general method is to glue the bonding surface between the aluminum plate and the interlayer It is designed as a special-shaped surface, but the special-shaped surface of the aluminum plate and the interlayer must be processed separately, especially the processing of the interlayer is more difficult, which leads to complex processes, high processing costs, and low efficiency;

[0005] The other is fixed in an empty box-type aluminum plate. Since the interlayer is set inside the aluminum plate, there will be a section without interlayer after splicing between the aluminum plates, which will lead to poor sound absorption and other effects.
