[0024] The following are specific embodiments of the utility model and the accompanying drawings to further describe the technical solution of the utility model, but the utility model is not limited to these embodiments. Embodiment 1

[0025] like Figure 1 As shown, the composite ceiling board includes a plastic particle extruded board 1, and the plastic particles are recycled plastic particles or finished plastic particles, such as recycling existing plastic material waste, re-melting the waste and granulating it, and finally extruding the plastic particle extruded board 1 with the lightweight characteristics of a plastic insulation board.

[0026] The design of the plastic particle extruded board 1 can significantly reduce the weight of the ceiling board and improve the construction efficiency.

[0027] A surface cement layer 2 is provided on at least one surface in the thickness direction of the plastic particle extruded plate 1, and the thickness of the surface cement layer 2 is less than the thickness of the plastic particle extruded plate 1. For example, the thickness of the surface cement layer 2 is 2mm-4mm, while the thickness of the plastic particle extruded plate 1 is 8mm-12mm. Preferably, a surface cement layer 2 is provided on the lower surface in the thickness direction of the plastic particle extruded plate 1.

[0028] The composite of the surface cement layer 2 and the plastic particle extruded board 1 can form a composite board that is convenient for subsequent construction, so as to further improve the construction efficiency.

[0029] For example, it is convenient to subsequently apply a putty layer on the surface cement layer, etc.

[0030] The combination of the surface cement layer 2, the plastic particle extruded board 1 and the glass fiber mesh 3 can ensure that the composite ceiling board has the advantage of being lightweight and can also ensure the structural strength of the composite ceiling board, so as to facilitate construction or transportation, etc. At the same time, the design of the glass fiber mesh 3 can prevent the ceiling board from cracking during the process of punching or nailing.

[0031] Secondly, the design of the surface cement layer 2 can also play a flame retardant role to ensure the safety of the use of the plastic particle extruded board 1 to the greatest extent.

[0032] A glass fiber mesh 3 is provided in the surface cement layer 2. Because several mesh holes of the glass fiber mesh 3 are filled with the surface cement layer 2, the glass fiber mesh 3 can improve the structural strength of the surface cement layer 2. The design of the glass fiber mesh 3 can simultaneously improve the structural strengths of the surface cement layer 2 and the plastic particle extruded board 1 to meet the requirements of suspended ceiling decoration. Embodiment 2

[0033] The structure and working principle of this embodiment are basically the same as those of the first embodiment, except that: Figure 2 As shown, a glass fiber mesh 3 is provided between the surface cement layer 2 and the plastic particle extruded plate 1 .

[0034] During processing, the plastic particle extruded board 1 is first extruded and formed, then the plastic particle extruded board 1 is squared and the glass fiber mesh 3 is spread on the surface of the plastic particle extruded board 1 in the thickness direction, and finally the surface cement layer 2 is formed. Embodiment 3

[0035] The structure and working principle of this embodiment are basically the same as those of the first embodiment, except that: Figure 3 As shown, two surfaces of the plastic particle extruded plate 1 in the thickness direction are respectively provided with surface cement layers 2. And a glass fiber mesh 3 is respectively embedded in each surface cement layer 2.

[0036] Secondly, in order to improve efficiency and flushness after installation, the surface cement layers 2 arranged on the two surfaces of the plastic particle extrusion plate 1 are symmetrically distributed and have equal thickness. Embodiment 4

[0037] The structure and working principle of this embodiment are basically the same as those of the first embodiment, except that: Figure 4 As shown, side cement layers 4 are respectively provided on four circumferential sides of the plastic particle extruded board 1, and the thickness of the side cement layers 4 is less than the thickness of the surface cement layer 2. The design of the side cement layers 4 ensures that the entire plastic particle extruded board 1 has a relatively good coating property to the greatest extent, so as to ensure the fireproof performance of the plastic particle extruded board 1 to the greatest extent.

[0038] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
