Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, a PVC fire-proof plate comprises a plate body 10, wherein the upper side and the lower side of the plate body 10 are both provided with a clamping strip 11, the plate body 10 is welded with an inner lining plate 12 through a cavity formed inside, a gravel pack 13 is filled inside a notch separated from the joint of the inner side of the cavity inside the plate body 10 and the inner lining plate 12, and a single-sided plate of the plate body 10 comprises an outer PVC layer 15, a protective outer layer 16, a flexible inner core 17, a protective inner layer 18 and an anti-abrasion layer 19.

The inside of the gravel pack 13 is also mixed with a colloid material, the inner side of the clamping strip 11 is provided with a connecting screw hole 14 penetrating through the plate body 10, and the gravel pack 13 can provide certain internal shock absorption and sound insulation effects and provide a better internal structure; the structure sequence from the outermost layer to the innermost layer of the single-sided board of the board body 10 is as follows; the plate body 10 is composed of double-sided plates on two sides, the outermost layers on two sides are the outer PVC layers 15 to provide external sealing, the inner anti-abrasion layer 19 provides an anti-abrasion effect which is in contact with the gravel packing 13, and the phenomenon that the plate body 10 is damaged from the inside due to excessive abrasion is avoided; the protective outer layer 16 and the protective inner layer 18 are both made of resin materials, the abrasion-proof layer 19 is made of an abrasive plate, and the flexible inner core 17 is made of flexible PVC plastic; an arc-shaped plate notch is formed between the plate body 10 and the clamping strip 11, the edge positions of the inner cavity of the plate body 10 are all arc-shaped notches, and the arc-shaped notches can provide a better supporting effect; the side opening of plate body 10, the side of plate body 10 is sealed through welded closing plate, provides the sealed effect of avris.
