[0039] The preparation method of the high-gloss halogen-free flame-retardant antibacterial PP material of the present invention comprises the following two steps:
[0040] (1) One-step granulation: such as figure 1 As shown, add PP and compatibilizer into the high-speed mixer in proportion, add diffusion oil for preliminary mixing, and then add mineral fillers, antioxidants, lubricants, nucleating agents and part of flame retardants in proportion to The high-speed mixer is used for mixing, and after mixing evenly, it is transported to the twin-screw extruder for mixing. The part of the flame retardant refers to 30%-40% of the total mass of the flame retardant. The aspect ratio of the twin-screw extruder is 40:1, and the temperature of each temperature zone of the extruder is one stage: 180-195°C; two stage: 195-205°C; three stage: 195-205°C; four stage: 205-215°C; 5th stage: 205-220°C; 6th stage: 210-220°C; 7th stage: 205-210°C; head 190-205°C. The extruded material is cool...
