[0003] However, the flame retardant effect of the existing composite aluminum plate is poor. Generally, a flame retardant layer is provided. However, the flame retardant particles inside the flame retardant layer are easily affected by moisture and oxidation for a long time, which easily leads to a decrease in the flame retardant effect.

[0010] In order to improve the heat insulation effect, the utility model is improved in that the heat insulation layer is made of rock wool.

[0011] (III) Beneficial effects

[0012] Compared with the prior art, the utility model provides a composite aluminum plate with good flame retardant effect, which has the following beneficial effects:

[0013] The composite aluminum plate with good flame retardant effect has a structure in which the flame retardant particles are arranged in a cavity opened in the aluminum layer, and a sealing plate is detachably connected to the cavity through a linking mechanism. Therefore, when the flame retardant particles are in the aluminum layer for a long time and are affected by factors such as oxidation and moisture, resulting in a decrease in the flame retardant effect, and the flame retardant particles need to be replaced, the sealing plate is separated from the cavity through the connecting mechanism, and then the flame retardant particles in the cavity can be taken out through an externally designated tool and replaced with new flame retardant particles, thereby avoiding the situation in which the flame retardant effect is decreased due to the failure to replace the damp and oxidized flame retardant particles in time.

In this embodiment, the heat insulation effect can be achieved by the heat insulation layer 3 on the back plate 2, and the heat can be isolated. The sound layer 4 can achieve the effect of sound insulation and noise reduction. The reinforcement layer 5 is made of carbon fiber. The carbon fiber has high strength, so as to improve the strength of the main body 1. The flame retardant particles in the cavity opened on the aluminum layer 6 can achieve the effect of flame retardancy. When the fire source burns the flame retardant particles, the flame retardant particles can achieve the effect of flame retardancy. When the flame retardant particles are inside the aluminum layer 6 for a long time, they are prone to oxidation and moisture. When the flame retardant particles need to be replaced, first push the damping block 15 hard to shrink the telescopic rod 14 in the groove 13, so that the damping block 15 is partially retracted into the groove 13, so that the damping block 15 is separated from the bottom of the bolt 9, and then the bolt 9 is twisted to separate the bolt 9 and the fixing plate 10 from the inner wall of the cavity, and then pull The positioning block 12 is separated from the positioning groove 11, so that the sealing plate 7 can be separated from the cavity, and then the flame retardant particles in the cavity can be cleaned out with an external tool (the external tool can be any small tool that can be inserted into the cavity, which is not described in detail here), and then new flame retardant particles can be replaced. When the damping block 15 in this structure is extended into the groove 13, when the telescopic rod 14 is retracted to the minimum distance, the damping block 15 will not completely enter the groove 13, and a part of it will be exposed, which is convenient for the staff to pull the damping block 15 outward, and the part of the damping block 15 extending out of the groove 13 will not affect the moving trajectory of the bolt 9. The drawings of this patent are schematic diagrams. In actual production, it is necessary to produce according to the actual size.
