Fireproof coating material

A fireproof coating material, comprising, in parts by weight, 40-80 parts of an aqueous curing agent, 20-50 parts of water and 80-200 parts of a mother liquor of the fireproof coating material, wherein the mother liquor of the fireproof coating material consists of 50-80 parts of a flame retardant, 15-25 parts of a dispersant and 190-220 parts of water, and the flame retardant has a molecular structural formula represented by a formula I and/or a formula II:

• wherein each of R1 and R2 is any one independently selected from a group consisting of substituted or unsubstituted divalent C1-C6 alkyl, divalent C3-C5 cycloalkyl, and substituted or unsubstituted divalent phenyl, each of R3 and R4 is any one independently selected from a group consisting of substituted or unsubstituted C1-C8 alkyl, C5-C7 cycloalkyl, and substituted or unsubstituted phenyl, and each of R5 and R6 is any one independently selected from a group consisting of substituted or unsubstituted C1-C8 alkyl, C5-C7 cycloalkyl, and substituted or unsubstituted phenyl.
