The invention provides an expansion type metal fireproof plugging plate which is applied to the technical field of fireproof plugging and is used for separating an ignition source from the outside when a building catches fire so as to prevent the fire from expanding and threatening the life health of personnel. Referring to fig. 1, fig. 1 is a schematic structural view of an intumescent metal fire-proof plugging plate of the present invention. As shown in the figure, the intumescent metal fire-proof plugging plate of the invention comprises a substrate 1, a high-expansion fire-proof coating 2 and a fire-proof coating layer 3 which are stacked in sequence. The base material 1 is a galvanized steel sheet, the high-expansion fireproof coating 2 is coated on the base material 1, and the high-expansion fireproof coating 2 is composed of colloidal resin, a flame retardant and a diluent.

The ammonium polyphosphate and the monopentaerythritol are matched to obtain the intumescent flame retardant, and the ammonium polyphosphate and the monopentaerythritol expand in heated volume to form a heat insulating layer and block heat transmission. The flame retardant used in the high-expansion fireproof coating 2 is a halogen-free flame retardant, no toxic and harmful gas is generated in the decomposition process, and no secondary damage is caused to trapped people.
The diluent adopted by the high-expansion fireproof coating 2 is ethyl acetate, the ethyl acetate has excellent solubility and can be used as the diluent, and carbon dioxide is generated when the ethyl acetate is heated and decomposed, so that the fire condition in a fire area is effectively inhibited.
The expansion type metal fireproof plugging plate is connected with a building through the anchor bolt, is convenient to assemble and disassemble, and cannot damage the building.
