The invention discloses a semi-aromatic polyamide composition with enhanced crystallinity and its preparation method, belonging to polyamide materials. The composition includes (by weight): 50-84 parts of semi-aromatic polyamide resin, 0.01-3 parts of imide nucleating agent, 15-45 parts of reinforcing material, and 0.1-5 parts of stabilizer. The preparation method: Extrude the blended materials in a twin-screw extruder at 310-325℃; wherein polyamide resin, imide nucleating agent and stabilizer are fed through the main feeding port, and reinforcing materials are added via the side feeding port. The imide nucleating agent optimizes the crystal structure and crystallinity of semi-aromatic polyamide, and synergizes with reinforcing materials to further enhance mechanical properties.
