The invention discloses a flame-retardant master batch as well as a preparation method and application thereof, and relates to the technical field of flame-retardant materials. The flame-retardant master batch comprises the following components in parts by weight: 40-75 parts of polyolefin resin, 20-55 parts of a flame retardant, 0.1-5 parts of a lubricant, 0.2-0.7 part of an antioxidant and 0-0.5 part of a light stabilizer, the flame retardant is a compound of a brominated flame retardant and a flame retardant A or a compound of a brominated flame retardant, a flame retardant A and a flame retardant B; the flame retardant A is a flame retardant containing-O-P = O-and-P-C-structures, and the flame retardant B is a halogenated phosphate flame retardant; the flame retardant A and the flame retardant B have melting points. The polyethylene film prepared from the flame-retardant master batch has excellent flame-retardant property and mechanical property, can keep the transparency of the film, and is suitable for
