Abstract

The invention discloses a high-fluidity halogen-free flame retardant reinforced nylon composite material and a preparation method thereof. According to the invention, high-fluidity nylon resin containing chain structural nylon 6 is adopted as matrix resin; 4.9 to 29.5 parts of halogen-free flame retardant and 0.1 to 0.5 part of antioxidant are added in a mixing machine for evenly mixing; the obtained mixture is melted and extruded through a screw extruder; a reinforcement component is added in the extruding process; and finally, a novel halogen-free flame retardant reinforced nylon composite material of the high-fluidity halogen-free flame retardant reinforced nylon composite material is obtained through drawing, cooling and pelletizing. The flame retardant reinforced nylon composite material has the characteristics of high melt fluidity, good environmental friendliness and flame retardance, good electric performance, excellent mechanical performance and the like; and obtained products have excellent surface performance, low warpage and high smoothness. The material can be widely applied in the field of electric plastic parts, such as casings, breakers, wire connection boxes, socket switches and the like of semiconductor devices such as IGBT (Insulated Gate Bipolar Transistor) and the like.

Description

technical field [0001] The invention relates to a halogen-free flame-retardant composite material, in particular to a high-fluidity halogen-free flame-retardant reinforced nylon composite material and a preparation method thereof. Background technique [0002] Reinforced nylon materials have the characteristics of high physical and mechanical properties, good heat resistance stability, and good electrical properties, and are widely used in industries such as automobiles, electronics, defense, and mechanical equipment. However, due to the low oxygen index of the reinforced nylon material (about 25%) and the fast burning speed, a large amount of dense smoke and molten droplets will be generated during the burning process, which is easy to spread the flame, which greatly limits its application in special fields such as electronic appliances. Applications, therefore, to improve the flame retardancy of reinforced nylon materials are imminent. [0003] At present, the commonly us...
