DETAILED DESCRIPTION

[0031] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Please refer to Figs. 1 to 4 In the embodiment, the fireproof wooden door comprises a cover joint plate 1 and a door plate frame 2, wherein the cover joint plate 1 comprises a frame 102 and rock wool 103 filled in the inside of the frame 102, the frame 102 has a cavity corresponding to the door plate frame 2 on the side facing the door plate frame 2, and a blocking plate 5 for positioning the rock wool 103 is fixedly installed in the inside of the cover joint plate 1.

[0033] In this way, the cover joint plate 1 and the door plate frame 2 can be mutually buckled and a sealable gap is reserved.

[0034] It is additionally explained that the door plate frame 2 is a rectangular plate frame with one side opening, the door plate frame 2 is synthesized by wood plastic material, and the surfaces of the cover joint plate 1 and the door plate frame 2 are coated with a fireproof coating layer 101.

[0035] Specifically, the fireproof coating layer 101 is a coating for improving the fireproof performance of a building, equipment or structure, and its main function is to delay the influence of fire and high temperature on the base material, so as to protect the integrity and safety of the structure. The fireproof coating layer comprises an inorganic fireproof coating layer and an organic fireproof coating layer, which are respectively made of inorganic materials such as cement, gypsum, etc. and polymer base materials such as epoxy resin, polyurethane, etc. The fireproof coating layer 101 of the present application selects a composite fireproof coating layer combined with the advantages of the ridge and mailing materials mentioned above, to provide better fireproof performance and adhesion.

[0036] In the embodiment, the width of the cover joint plate 1 is greater than the size of the door plate frame 2, and a sealing gasket 3 is pasted on the part of the cover joint plate 1 extending to the side surface of the door plate frame 2, wherein the sealing gasket 3 is in the shape of a rectangular frame with the edges flush with the cavity opening on the cover joint plate 1.

[0037] In order to improve the tightness of the connection between the door plate frame 2 and the cover joint plate 1, a sealing rubber strip 4 is integrally extended on one end of the sealing gasket 3 flush with the cavity opening of the cover joint plate 1, the cross section of the sealing rubber strip 4 is circular, and the sealing rubber strip 4 is attached to the outer wall of the door plate frame 2 to close the gap between the door plate frame 2 and the cover joint plate 1.

[0038] In this way, by attaching and sealing with the sealing rubber strip 4, the use of the wooden door in the normal state can be maintained, and when a high-temperature combustion environment occurs, the sealing rubber strip 4 can be thermally deformed at high temperature, thereby providing a gap for the fire retardant 601 to overflow.

[0039] Further, the door plate frame 2 is provided with a fireproof structure for improving the overall fireproof performance of the wood-plastic door, wherein the fireproof structure comprises a fireproof plate frame 6 in the inner cavity of the door plate frame 2, a fire retardant 601 in the fireproof plate frame 6, and a heat delay structure between the fireproof plate frame 6 and the inner cavity wall of the door plate frame 2.

[0040] In the specific use process, when the wood-plastic door is burned and generates high temperature, the heat delay structure can be deformed by heat to extrude the fire retardant 601 in the fireproof plate frame 6.

[0041] In this embodiment, the fireproof plate frame 6 is continuously distributed with openings for the release of the fire retardant 601 on the side surface of the cover joint plate 1, wherein the openings are circular holes, and the opening surfaces are covered with a film for temporarily closing the openings on the fireproof plate frame 6.

[0042] Further, the heat delay structure comprises a cover plate 602 slidingly connected to the fireproof plate frame 6, a fixed strip 605 fixedly installed on the inner wall of the door plate frame 2, a fireproof strip 603 bonded to the fixed strip 605, and a rubber rod 604 connected to the fireproof strip 603 and the cover plate 602.

[0043] It is further explained that the rubber rod 604 is composed of a support rod in the middle and rubber heads at both ends, the rubber heads provide the possibility of swinging movement of the rubber rod 604, and the support rod provides a certain strength of the rubber rod 604.

[0044] In this way, the fireproof strip 603 can extrude the rubber rod 604 by expanding under heat, and the rubber rod 604 is connected to the fireproof strip 603 and the cover plate 602 in two groups of inclined connection.

[0045] Since the rubber rod 604 is inclined to the cover plate 602, under the expansion and extrusion, the rubber rod 604 can extrude the cover plate 602 in the fireproof plate frame 6.

[0046] The working principle of the above embodiment is that when a fire occurs or the wood-plastic door burns outside, the wood-plastic door hinders the normal combustion of the fire through the rock wool 103 in the inside of the cover joint plate 1 on the surface of the wood-plastic door. Since the rock wool 103 has a certain thickness under the extrusion of the sealing plate 5, the combustion phenomenon of the wood-plastic door as a combustion material can be reduced. At the same time, the temperature is continuously transmitted along the cover joint plate 1 and the door plate frame 2. The fireproof strip 603 located in the door plate frame 2 expands under the high temperature. At this time, the rubber rod 604 located between the fireproof strip 603 and the cover plate 602 is extruded synchronously with the fireproof strip 603 to extrude the cover plate 602 on the fireproof plate frame 6. With the conduction of temperature, the sealing rubber strip 4 between the door plate frame 2 and the cover joint plate 1 deforms. The film attached to the opening surface of the fireproof plate frame 6 melts. At this time, the cover plate 602 can extrude and overflow the fire extinguishing agent stored in the fireproof plate frame 6 from the gap, so that the wood-plastic door has a certain internal release capacity to cope with the combustion, and the temperature resistance of the wood-plastic door is improved.
