The invention relates to the technical field of molding compound production, in particular to a high-performance amino molding compound for structural parts and a preparation method of the high-performance amino molding compound. Comprising the following raw materials in parts by weight: 30-70 parts of amino resin powder, 10-25 parts of an inorganic filler, 0.3-1 part of a dispersant, 0.5-1 part of a lubricant, 0.5-1.5 parts of a release agent, 0.1-1 part of a coupling agent, 0.1-1 part of a pigment, 0-1 part of an accelerant, 1-3 parts of a granulation aid and 10-50 parts of glass fibers. The glass fiber reinforced granular amino molding compound is prepared by adopting a kettle type stirring granulation process technology, the molding compound is granular, and glass fibers are wrapped by resin powder and the like on the outer layer. In the preparation process of the amino molding plastic granules, powder such as amino resin powder and the like gathers into granules by taking glass fibers as a core under the
