Described a kind of fireproof door leaf, the granularity of its said white afrodite particle are 20 orders-500 orders.

Described a kind of fireproof door leaf, the mesh shape of its said grid is a polygon, the thickness of grid equates with the thickness of edge sealing framework.

Described a kind of fireproof door leaf, its said bottom surface layer and surface course are plank or steel plate after soaking through fire-resistant fluid.

Described a kind of fireproof door leaf, its said edge sealing framework are the plank after cold bundle steel plate or process fire-resistant fluid soak.

White afrodite in the fire proofing material that the present invention adopts is natural silicon ore deposit; Essential mineral consists of quartz and kaolinite, and refractory temperature is 1650 ℃-1730 ℃, and compressive strength is 96-116 MPA; Coefficient of thermal expansion is 0.4-1.2 at 1000 ℃, and the white afrodite of monoblock is used to make refractory brick.White afrodite particle price is 160-580 unit/ton at present, all is superior to expanded perlite.

Advantage of the present invention: simple in structure, be easy to produce, fire resistance period is long, the refractory temperature height, cost of production is low, and anti-pressure ability is strong, and steady quality has met and exceeded the requirement of national GB12955-2008 labeled door new standard fully, and fire resistance period has reached 3 h.
