Embodiment 1
[0023] Proportion according to the following mass percentage composition: antimony trioxide 85% (0.03μm, Hunan Chenzhou Mining Co., Ltd.), homopolypropylene (PPH) 14% (grade EP500N, China Sea Shell Petrochemical Company), modified ethylene Bis-fatty acid amide (ethylene bis-fatty acid amide grafted with maleic anhydride) 1% (commercially available conventional model). After the above materials are accurately weighed, PPH and modified ethylene bis fatty acid amide are added to the pressurized tumbling internal mixer, the temperature in the internal mixing chamber is controlled at 150°C, the rotor speed is 40r / min, and the internal mixing time is 3min. After the material is melted, add the nano antimony trioxide powder into the internal mixer three times, with an interval of 3 minutes between feeding each time; after adding all the materials, banbury for 5 minutes. The rubber head after the above-mentioned internal mixing is transported to the hopper of the single-screw extruder...
Embodiment 2
[0025] Proportion according to the following mass percentage composition: antimony trioxide 90% (0.05μm, Hunan Chenzhou Mining Co., Ltd.), homopolypropylene (PPH) 8.5% (grade EP500N, China Ocean Shell Petrochemical Company), modified ethylene Bis-fatty acid amide (ethylene bis-fatty acid amide grafted with maleic anhydride) 1.5% (commercially available conventional model). After accurately weighing the above materials, add PPH and modified ethylene bis fatty acid amide into the pressurized tumbling internal mixer, control the temperature in the internal mixing chamber to 150-160°C, the rotor speed to 40r / min, and the internal mixing time to be After the material is melted, add the nano antimony trioxide powder into the internal mixer three times, with an interval of 5 minutes between feeding each time; after all the materials are added, banbury for 10 minutes. The above-mentioned rubber head after banburying is transported to the hopper of the single-screw extruder through the...
Embodiment 3
[0027] Proportion according to the following mass percentage composition: antimony trioxide 95% (0.08μm, Hunan Chenzhou Mining Co., Ltd.), random copolymerized polypropylene (PPR) 4.5% (brand R370Y, Korea SK Company), modified ethylene Bisfatty acid amide (ethylene bisfatty acid amide grafted with divinylbenzene) 0.5% (commercially available conventional model). After the above materials are accurately weighed, PPR and modified ethylene bis fatty acid amide are added to the pressurized tumbling internal mixer. The temperature in the internal mixing chamber is controlled at 160°C, the rotor speed is 45r / min, and the internal mixing time is 5min. After the material is melted, add the nano antimony trioxide powder into the internal mixer three times, with an interval of 4 minutes between each feeding; after adding all the materials, banbury for 8 minutes. The above-mentioned rubber head after banburying is transported to the hopper of the single-screw extruder through the conveyo...
