The invention discloses a fluorosiloxane release agent. A chemical structural formula of the fluorosiloxane release agent is shown, wherein an x in the chemical structural formula is equal to 1-5000,a y in the chemical structural formula is equal to 1-5000, a z in the chemical structural formula is equal to 1-5000, an s in the chemical structural formula is equal to 1-5000, and a t in the chemical structural formula is equal to 1-5000; an R1 in the chemical structural formula represents phenyl or aromatic groups; an R2 in the chemical structural formula represents CF<2*n+1> or CH<2*n+1>, and the n is equal to 1-18; an X in the chemical structural formula represents one of CH<2*m>, O, CO, COO and S, and the m is equal to 0-10; a Y in the chemical structural formula represents curing groups or adhesion promoting groups. The fluorosiloxane release agent is made of raw materials including, by weight, 100 parts of main chain fluoroalkyl silane, 10-100 parts of phenyl or aromatic-base siloxane, 10-100 parts of vinyl siloxane, 10-100 parts of hydrogen-containing siloxane, 10-100 parts of alkyl siloxane and 0.1-10 parts of end capping agents. The raw materials are polymerized toobtain the fluorosiloxane release agent. A chemical structural formula of main chain fluorosiloxane polymers is shown, wherein an n in the chemical structural formula is equal to 1-18, an X in the chemical structural formula represents one of CH<2*m>, O, CO, COO and S, an m in the chemical structural formula is equal to 0-10, and a W in the chemical structural formula represents C1-C4 alkyl. Compared with existing fluorosiloxane release agents, the fluorosiloxane release agent has the advantages that the fluorosiloxane release agent is easy and convenient to use, and anchoring agents can beomitted.
