Yancheng Senyi New Materials obtained the patent for composite fireproof door core panels, which improves the rigidity of the door core and avoids deformation.

According to news from the financial industry on October 21, 2024, information from the State Intellectual Property Office shows that Yancheng Senyi New Materials Co., Ltd. has obtained a patent called \”A Composite Fireproof Door Core Panel\” and authorized Announcement number CN 221823681 U, application date is February 2024.

The patent summary shows that the utility model relates to the technical field of building panels, and discloses a composite fireproof door core panel, which includes two aluminum plates. The inner sides of the two aluminum plates are fixedly connected with a fireproof base layer, and two fireproof The inner sides of the base layer are fixedly connected with honeycomb panels, the outer sides of the two fire-proof base layers are provided with bumps, the inner sides of the two aluminum plates are provided with multiple perforations, and the two fire-proof The protrusions on the outer side of the base layer are respectively embedded into the perforations on the inner side of the two aluminum plates. The thickness of the honeycomb board is two to three centimeters. This utility model improves the rigidity of the door core, avoids deformation, reduces the overall weight of the door core, and avoids the weight of the door core. Excessive weight causes pressure on the joints after the door leaf is installed. While ensuring the basic fire protection performance, it also has toughness, moisture-proof performance and thermal insulation performance.
