Abstract

The invention discloses a halogen-free flame-retardant highly-temperature-resistant polytetramethylene adipamide composite material and a preparation method thereof. The composite material is preparedfrom the following components in percentage by weight: 25-35% of polytetramethylene adipamide, 15-25% of nylon 66, 3-7% of a toughening compatibilizer, 12-18% of a halogen-free flame retardant, 20-30% of glass fibers, 0.1-0.3% of an antioxidant, 0.3-0.7% of a UV resistant agent, 0.2-0.4% of a heat stabilizer and 3-7% of glass beads. The preparation method comprises the following steps: weighing the various raw materials in percentage by weight, and mixing the various weighed raw materials; and adding the mixed materials into a twin-screw extruder, and performing extruded granulation. The polytetramethylene adipamide is modified, so that the prepared polytetramethylene adipamide composite material has the characteristic of high temperature resistance.
