Description

Technical Field

[0001] This utility model relates to the field of sound insulation board technology, specifically a recycled plastic sound insulation composite board. Background Technology

[0002] Recycled plastics refer to a new type of material that is made by reprocessing waste plastic products into plastic granules or plastic products after a series of processes such as crushing, washing, screening, and drying. Recycled plastics are a resource utilization of waste plastics, which is of great significance for environmental protection and sustainable development. Making them into sound insulation boards is one way to utilize recycled plastics.

[0003] Currently, sound insulation boards made from recycled plastics have reduced strength and poor sound insulation performance on their own. Therefore, we propose a composite sound insulation board made from recycled plastics. Utility Model Content

[0004] The purpose of this utility model is to provide a recycled plastic sound insulation composite board, which has the advantages of improving the strength of the recycled plastic sound insulation board while improving its sound insulation performance. It solves the problem that the strength of the sound insulation board made of recycled plastic is reduced and the sound insulation effect of the board itself is not good.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a recycled plastic sound insulation composite board, comprising a sealing plate and a sound insulation composite board body, wherein the sound insulation composite board body is vertically continuous, a corrugated rib is provided inside the sound insulation composite board body, sound insulation cotton is inserted inside the sound insulation composite board body, and a sealing plate is fixedly installed inside the sound insulation composite board body near the upper and lower surfaces.

[0006] Preferably, the outer surface of the sound insulation composite panel is provided with a wear-resistant coating. The wear-resistant coating can improve the wear resistance of the surface of the sound insulation composite panel, so as to avoid wear on the surface of the sound insulation composite panel. At the same time, it also plays a role in isolation, preventing the surface of the sound insulation composite panel from contacting the air and being exposed to ultraviolet radiation, thus preventing oxidation of the sound insulation composite panel and delaying the aging of the sound insulation composite panel, thereby extending the service life of the sound insulation composite panel.

[0007] Preferably, the front surface of the sound insulation composite panel body is provided with a main slot, and the rear surface of the sound insulation composite panel body is provided with a main insert. When splicing the sound insulation composite panel bodies, the main insert between adjacent sound insulation composite panel bodies can be inserted into the main slot to facilitate the splicing between the sound insulation composite panel bodies.

[0008] Preferably, raised retaining strips are symmetrically distributed on both sides of the inner wall of the main slot, and retaining grooves are symmetrically distributed on both sides of the outer surface of the main insert. After the sound insulation composite board body is spliced, the raised retaining strips are inserted into the retaining grooves, which plays a restrictive role in preventing the main insert from easily slipping out of the main slot.

[0009] Preferably, the front surface of the sound insulation composite panel body is symmetrically provided with side inserts on both sides of the main slot, and the rear surface of the sound insulation composite panel body is symmetrically provided with side slots on both sides of the main inserts. After the sound insulation composite panel body is spliced, the side inserts are inserted into the side slots to improve the stability of the spliced ​​sound insulation composite panel body.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model achieves the effect of improving the strength of recycled plastic sound insulation board and its sound insulation performance by setting the sound insulation composite board body, corrugated ribs and the outer surface. The corrugated ribs inside the sound insulation composite board body improve the strength of the sound insulation composite board body, and the outer surface of the corrugated ribs and the inner wall of the sound insulation composite board body form a cavity that can accommodate sound insulation cotton. The sound insulation cotton gives the sound insulation composite board body a good sound insulation effect.

[0012] 2. By setting a wear-resistant coating, this utility model can improve the wear resistance of the surface of the sound insulation composite board, thereby avoiding wear on the surface of the sound insulation composite board. It also plays a role in isolation, preventing the surface of the sound insulation composite board from contacting the air and being exposed to ultraviolet radiation, thus preventing oxidation of the sound insulation composite board and delaying its aging, thereby extending the service life of the sound insulation composite board.

[0013] 3. This utility model achieves the effect of facilitating the splicing of the main body of the sound insulation composite board by setting the main slot and the main insert. When splicing the main body of the sound insulation composite board, the main insert between the adjacent sound insulation composite board bodies can be inserted into the main slot.

[0014] 4. By setting protruding clips and slots, this utility model achieves the effect of improving the firmness between the main bodies of the sound insulation composite board after splicing. After the main bodies of the sound insulation composite board are spliced, the protruding clips are inserted into the slots, which restricts the main insert from moving out of the main slot, so as to prevent the main insert from easily slipping out of the main slot.

The inflection points of the corrugated rib 5 are fixedly connected to the inner wall of the sound insulation composite board body 2. The sound insulation composite board body 2 and the corrugated rib 5 are integrally extruded from recycled plastic. Sound insulation cotton 4 is inserted inside the sound insulation composite board body 2. A cavity that can accommodate the sound insulation cotton 4 is formed between the outer surface of the corrugated rib 5 and the inner wall of the sound insulation composite board body 2. The sound insulation composite board body 2 is located near the upper and lower surfaces. Each part is fixedly installed with a sealing plate 1, which seals the top and bottom ends of the sound insulation composite panel body 2 to prevent rainwater from entering the interior of the sound insulation composite panel body 2. The outer surface of the sound insulation composite panel body 2 is provided with a wear-resistant coating 3. The wear-resistant coating 3 can improve the wear resistance of the surface of the sound insulation composite panel body 2 to prevent the surface of the sound insulation composite panel body 2 from being worn. At the same time, it also plays a role in isolation, preventing the surface of the sound insulation composite panel body 2 from contacting the air and being exposed to ultraviolet radiation, thus preventing oxidation of the sound insulation composite panel body 2, delaying the aging of the sound insulation composite panel body 2, and thus extending the service life of the sound insulation composite panel body 2.

[0023] When this utility model is in use, the corrugated ribs 5 inside the sound insulation composite board body 2 improve the strength of the sound insulation composite board body 2, and a cavity that can accommodate the sound insulation cotton 4 is formed between the outer surface of the corrugated ribs 5 and the inner wall of the sound insulation composite board body 2. The sound insulation cotton 4 enables the sound insulation composite board body 2 to have a good sound insulation effect.
