Embodiment 3
[0029] A method for preparing environmentally friendly flame retardant glass fiber reinforced PA6 / PPO alloy material with high CTI value and high GWIT value, the method is as follows: Weigh raw materials according to weight ratio: PA6 23%, PPO 22%, compound flame retardant 20%, antimony trioxide 4.3%, glass fiber 20%, commercially available maleic anhydride grafted PPO 10%, antioxidant (1330) 0.1%, iron oxide 0.6%; put into high mixer and mix for 2 minutes, The material is discharged, and then extruded and granulated with a twin-screw extruder, the processing temperature is 240° C., and the screw rotation speed is 300 rpm.
[0030] The compound flame retardant is compounded by our company itself, and is composed of three components, and its mass percentage is BPS: 50%; magnesium hypophosphite: 25%; talcum powder: 25%.
Embodiment 4
[0032] A high CTI value, high GWIT value environmentally friendly flame retardant glass fiber reinforced PA6 / PPO alloy material preparation method, the method is as follows: Weigh raw materials according to weight ratio: PA6 46%, PPO 20%, compound flame retardant 6 %, antimony trioxide 3%, glass fiber 21%, commercially available maleic anhydride grafted PPO 2%, antioxidant (1330) 1%, iron oxide 1%; put into the high mixer and mix for 5 minutes, and the The material is then extruded and granulated with a twin-screw extruder, the processing temperature is 240° C., and the screw speed is 400 rpm.
[0033] The compound flame retardant is compounded by our company itself, and is composed of three components, and its mass percentage is BPS: 50%; magnesium hypophosphite: 25%; talcum powder: 25%.
[0034] The glass fiber is an alkali-free glass fiber, and the glass fiber is added into the silane coupling agent to make its surface treated with the silane coupling agent.
Embodiment 5
[0036] A high CTI value, high GWIT value environmentally friendly flame retardant glass fiber reinforced PA6 / PPO alloy material preparation method, the method is as follows: Weigh raw materials according to weight ratio: PA6 25%, PPO 41%, compound flame retardant 6 %, antimony trioxide 5%, glass fiber 20%, commercially available maleic anhydride grafted PPO 2%, antioxidant (1330) 0.5%, iron oxide 0.5%; The material is then extruded and granulated with a twin-screw extruder, the processing temperature is 240° C., and the screw speed is 350 rpm.
