The invention provides a composite fireproof material, which comprises a quartz sand layer (1), a fireproof rock wool layer (2), and an aluminum silicate fiber layer (3). The quartz sand layer (1) is arranged above the fireproof rock wool layer (2), the aluminum silicate fiber layer (3) is arranged under the fireproof rock wool layer (2), and the quartz sand layer (1), the fireproof rock wool layer (2), and the aluminum silicate fiber layer (3) are tightly laminated together. The fireproof rock wool layer is clamped by an upper quartz sand layer and a lower aluminum silicate layer so as to fix the fireproof rock wool layer to a certain degree; at the same time, the external quartz sand layer has a good thermal insulation effect, the fireproof load of the center layer and inner layer is relieved in a certain degree; the composite fireproof material has the advantages of simple structure and low cost, and a good fireproof function can be realized through simple structural improvement. 本发明提供种复合防火材料，包括石英砂层(1)、耐火岩
