Examples
Embodiment 1
[0029] The weight ratio of 64% POM, 10% red phosphorus microcapsules, 2% triphenyl phosphate, 4% melamine, 5% phenolic resin, 14% conductive carbon black, 0.2% silicon dioxide, 0.3% antioxidant 245 and 0.5 % Lithium stearate was premixed on a high-speed mixer for 10 minutes, then melted and extruded in a twin-screw extruder at 165-175°C to granulate, and then injection-molded on an injection molding machine.
Embodiment 2
[0031] The weight ratio of 62% POM, 10% red phosphorus microcapsules, 2% RDP, 4% melamine, 5% phenolic resin, 16% conductive carbon black, 0.2% silicon dioxide, 0.3% antioxidant 245 and 0.5% polyethylene The diol is pre-mixed on a high-speed mixer for 10 minutes, and then melted and extruded at 165-175°C in a twin-screw extruder to make pellets, and then injection-molded on an injection molding machine.
Embodiment 3
[0033] Put 64.3% POM, 10% red phosphorus microcapsules, 4% melamine, 5% phenolic resin, 14% conductive carbon black, 0.2% aluminum oxide, 0.3% antioxidant 1010 and 2% polyethylene wax on a high-speed mixer Pre-mixed for 10 minutes, then melt-extruded and granulated in a twin-screw extruder at 165-175°C. Then the extruded particles were dried at 105° C. and mixed in a kneader for 2 minutes, and then injection-molded on an injection molding machine.
