Referring to fig. 1-2, the present invention provides a technical solution: a clad door with good fireproof performance comprises a main body frame 1, a door core 2, a base plate 3 and an outer plate 4, wherein the main body frame 1 is of a frame-shaped structure integrally and is hollow inside; a door core mounting groove 11 is arranged in the middle of an inner groove of the main body frame 1, cushion grooves 12 are arranged on two sides of the door core mounting groove 11, the door core 2 is correspondingly arranged in the door core mounting groove 11, and two cushion plates 3 are arranged and are respectively arranged in the corresponding cushion grooves 12 in a matching manner; the backing plate 3 is flush with the surface of the main body frame 1, two outer plates 4 are arranged, and the outer plates 4 are arranged on two sides of the main body frame 1 and are flush with the edge of the main body frame 1; fixing holes 41 are formed along the edges of the outer plate 4, and pins are arranged in the fixing holes 41 in a matching mode and are connected with the main body frame 1.

Further, the main body frame 1 is a metal frame, the door core 2 is a rock wool plate, the backing plate 3 is a perlite fireproof plate, and the outer plate 4 is a cold-rolled hot-dip galvanized steel plate.

Further, a thermal expansion sealing strip 31 is arranged between the side surface of the backing plate 3 and the backing groove 12, and a thermal insulation cushion rubber pad 32 is arranged between the backing plate 3 and the door core 2.

Further, the whole backing plate 3 is of a prismatic table structure, the groove wall of the backing groove 12 is an inclined plane, and the inclination angle of the groove wall is 45-60 degrees.

Further, the thickness ratio of the door core installation groove 11 to the cushion groove 12 on the main body frame 1 is 1: 0.4-0.6, and the two pad grooves 12 have the same size.

The working principle is as follows: the main body frame 1 made of metal materials can effectively ensure the strength of the whole door body structure, further ensure that the door body has long enough service life and simultaneously avoid foreign objects from being impacted and damaged; the door core 2 that the rock wool board material was made and backing plate 3 that the pearlite guard plate material was made all have light, fire prevention high temperature resistance characteristic, can alleviate the quality of the whole door body on the one hand, and the holistic protection high temperature resistance performance of the door body is guaranteed to on the other hand, guarantees the fire behavior at the door body in the scene of a fire.
