Embodiment 1

[0011] Example 1: 30 kg of polyethylene terephthalate (PET) and 23 kg of polycaprolactam (PA) were dried at 130° C. for 4 hours. Pour the dried polyethylene terephthalate (PET) and polycaprolactam (PA) into a high-speed mixer and stir at a low speed. While stirring, add 6.5kg of toughening compatibilizer, 7kg of brominated flame retardant, 2kg of antimony trioxide, 1.2kg of zinc borate and 0.3kg of antioxidant, and stir for 2 minutes. Add the mixed raw materials into the twin-screw extruder and blend them for extrusion. The blending temperature is 245-260°C, the screw speed is 350r / min, 30kg of glass fiber is added to the glass fiber port, and the product is extruded, water-cooled, and pelletized. The produced material was dried at 120°C for 4 hours, and then standard mechanical property test specimens were prepared on an injection molding machine. The injection pressure is 60-90Mpa, the barrel temperature is 255-270°C, the mold temperature is 80°C, and the injection cycle i...

Embodiment 2

[0014] Example 2: 27kg of polyethylene terephthalate (PET) and 25kg of polycaprolactam (PA) were dried at 130°C for 4 hours. Pour the dried polyethylene terephthalate (PET) and polycaprolactam (PA) into a high-speed mixer and stir at a low speed. While stirring, add 6kg of toughening compatibilizer, 6.5kg of brominated flame retardant, 2kg of antimony trioxide, 1kg of zinc borate and 0.5kg of antioxidant, and stir for 2 minutes. Add the mixed raw materials into the twin-screw extruder and blend them for extrusion. The blending temperature is 245-260°C, the screw speed is 350r / min, 32kg of glass fiber is added to the glass fiber port, and the product is extruded, water-cooled, and pelletized. The produced material was dried at 120°C for 4 hours, and then standard mechanical property test specimens were prepared on an injection molding machine. The injection pressure is 60-90Mpa, the barrel temperature is 255-270°C, the mold temperature is 80°C, and the injection cycle is 40s....

Abstract

The invention relates to a high-glow-wire flame-retardant reinforced PET / PA alloy material and a production method thereof, which belong to the field of polymer materials and use polyethylene terephthalate, polycaprolactam, glass fiber, toughening compatibilizer, Brominated flame retardant, antimony trioxide, zinc borate and antioxidant as raw materials, it can be prepared by the following methods: drying, mixing, extrusion, pelletizing, and finally made into high glow wire flame retardant Glass fiber reinforced PET / PA alloy material, its technical feature is that the raw material composition includes: polyethylene terephthalate 20-30%, polycaprolactam 20%-30%, glass fiber 30-35% in weight percentage , Toughening compatibilizer 5-8%, brominated flame retardant 6-8%, antimony trioxide 1.5-2.5%, zinc borate 1-1.5%, antioxidant 0.3-0.5%. The high glow wire flame-retardant glass fiber reinforced PET / PA alloy material produced by the invention has good fluidity, high glow wire performance and mechanical properties, and the production process is simple.

Description

technical field [0001] The invention relates to the field of organic polymer materials, in particular to a highly glow-wire flame-retardant reinforced polyethylene terephthalate (PET) / polycaprolactam (PA) alloy material. Background technique [0002] We know that in addition to the UL94 vertical burning test requirements, the socket inner frame and transformer frame used in the fields of electronic appliances also need to meet the glow wire test requirements, so as to ensure that the electrical appliances are overloaded during use. It is flame retardant and ensures the safety of electrical appliances, life and property. Traditional flame-retardant reinforced polyester raw materials can basically meet the test of vertical burning performance after being made into finished products, but they do not perform well in the glow wire test. In recent years, Haier, Midea and other large electronic and electrical groups have continuously increased their glow wire requirements for fla...
