Description

Technical Field

[0001] The utility model relates to a composite corrugated board with novel sound-absorbing holes, belonging to the technical field of novel decorative materials. Background Art

[0002] At present, corrugated boards made of aluminum or steel plates are widely used in large modern public buildings such as theaters, concert halls, exhibition halls, and gymnasiums. However, the disadvantages of traditional corrugated boards are that they are expensive, their surface is prone to aging, fading and losing its luster; and they are difficult to effectively resist the erosion of acid rain, air pollution and ultraviolet light. Utility Model Content

[0003] The purpose of the utility model is to provide a composite corrugated board with novel sound-absorbing holes, thereby overcoming the deficiencies in the prior art.

[0004] The utility model is realized by the following technical scheme, including a panel and a core material bonded by epoxy resin adhesive; the panel is an aluminum plate with a thickness of 1.0 to 1.2 mm, and sound-absorbing holes are evenly distributed on the surface of the panel, and the size of the sound-absorbing holes is 0.4 mm long and 0.04 mm wide; the surface of the panel is coated with fluorocarbon resin, and the bottom surface of the panel has an accommodating space; the core material is a corrugated steel plate or aluminum plate, and the core material is laminated and arranged in the accommodating space, and a layer of sound-absorbing cloth is also laid between the panel and the core material.

[0005] The beneficial effects of the present invention are: 1. Maximum strength ensures the bonding strength between the panel and the core material and uniform compounding; 2. The use of fluorocarbon resin coating can effectively resist the erosion of acid rain, air pollution and ultraviolet light, and has the characteristics of long service life, strong adsorption capacity, good gloss, aging resistance and no discoloration; 3. The surface is flat and can be used as a large decorative panel without deformation. The surface coating is uniform and easy to clean, with rich colors, good sound insulation and heat insulation performance, and has excellent fire resistance, reaching fire protection grade A.

[0007] In order to make the purpose, technical solutions and advantages of the present invention more clear, the following is a detailed description of the present invention with reference to the attached drawings. Figure 1, the utility model is further described in detail. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the utility model; in addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other. The utility model will be described in more detail below with reference to the accompanying drawings. In the various drawings, the same elements are represented by similar figure numerals. For the sake of clarity, the various parts in the drawings are not drawn to scale.

[0008] The utility model includes a panel 1 and a core material 3 bonded together using an epoxy resin adhesive 2, ensuring maximum strength and uniform bonding between the panel 1 and the core material 3. Sound-absorbing holes 13 are evenly distributed on the surface of the panel 1, each measuring 0.4 mm in length and 0.04 mm in width. The surface of the panel 1 is coated with a fluorocarbon resin coating 11. The fluorocarbon resin coating is effective in resisting acid rain, air pollution, and ultraviolet light erosion, and has the advantages of long service life, strong adsorption capacity, good gloss, aging resistance, and no discoloration. The surface is smooth and can be used as a large decorative panel without deformation. The surface coating is uniform, easy to clean, and colorful, and can effectively resist acid rain, air pollution, and ultraviolet light erosion. The bottom surface of the panel 1 has a accommodating space 12; the panel 1 is an aluminum plate with a thickness of 1.0 to 1.2 mm, the surface of the panel 1 has a fluorocarbon resin coating 11, the core material 3 is a corrugated steel plate or aluminum plate, the core material 3 is fitted in the accommodating space 12, and a layer of sound-absorbing cloth 4 is also laid between the panel 1 and the core material 3; the sound insulation and heat insulation performance are good.

[0009] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
