The invention belongs to the technical field of chemical additives, and particularly relates to silicone amide wax and a preparation method thereof. The structural formula of the silicone amide wax isas a formula 1 or a formula 2; in the formula 1 and the formula2, R1 and R2 are alkyls or H, and at least one of the R1 and the R2 is an alkyl; and in the formula 2, R3 and R4 are alkyls or H, and atleast one of the R3 and R4 is an alkyl. The silicone amide wax is prepared by carrying out a catalytic reaction under the condition of stirring at a temperature of 50-200 DEG C by taking carboxyl-containing polysiloxane and aliphatic amine as raw materials. According to the silicone amide wax, a siloxane structural unit and an amide structure are innovatively spliced together in a same molecule,so that the silicone amide wax has the characteristics of low surface tension, superior lubrication and demoulding performance, and friction resistance, and has more excellent performance than a fattyacid amide compounding siloxane lubricant, and the cost is lower.
