Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of PVC wallboard, especially to a PVC wallboard flame-retardant structure. BACKGROUND

[0002] With the progress of decoration technology and materials, more and more people use PVC wallboard to decorate the wall, which is not only convenient, but also can be designed according to personal preferences. Compared with traditional cement wall, the fire resistance of PVC wallboard is poor, so it is necessary to inject fireproof material into the wallboard. For example, patent application No. CN202120396156.1 discloses a fireproof and flame-retardant PVC wallboard. The patent connects a flame-retardant layer 2 to the outer surface of the PVC wallboard body 1, which has excellent flame-retardant effect. The upper and lower surfaces of the flame-retardant layer 2 are fixedly connected with flame-retardant films 3, which also have flame-retardant properties to protect the internal PVC wallboard body 1. The through hole is filled with a foaming layer 4 made of foaming material. In the event of a fire, even if the flame-retardant films 3 and the flame-retardant layer 2 are burned, the foaming material filled in the through hole can generate foam to cover the surface of the wall, forming an insulating layer to inhibit the further spread of the fire.

[0003] The existing technology mainly uses flame-retardant layer and foaming layer for fireproofing. However, the connection between PVC wallboards is mainly through the embedding of protrusions and grooves, which has low connection strength and lacks stability. Therefore, the present application provides a PVC wallboard flame-retardant structure to increase the connection stability between PVC wallboards. UTILITY MODEL CONTENTS
