The invention discloses a polyamide wax micropowder synthesizing formula and a production technology thereof. One or more than two kinds of fatty acids and more than two kinds of amines carry out synthetic reaction with a catalyst and an auxiliary agent, wherein the carbon chain of the main frame of the fatty acids contains 4-18 carbon molecules; the molar ratio of the fatty acids to the amines is0.8-1.2:1; the adding amount of the catalyst is 0.1permillage -0.5 permillage of the total weight of the fatty acids and the amines; and the adding amount of the auxiliary agent is 0.5%-1.5% of the total weight of the fatty acids and the amines. The production process comprises the following steps: firstly, using the synthesizing formula for polyamide synthetic reaction; secondly, preparing polyamide slices; then, pulverizing the polyamide slices into micropowder; and finally, classifying the micropowder by using a particle classifier to obtain the polyamide wax micropowder. The polyamide waxmicropowder produced by the invention is used as a rheological additive to be applied to the fields such as solvent based coatings, ink, daily chemical products, adhesives, sealants and the like, thereby providing the systematic thixotropic viscosity and greatly improving the storage stability, the anti-sagging performance and the anti-settling performance of products.
