Embodiment 1
[0021] Example 1: In parts by weight, weigh 50 parts of antimony trioxide, 30 parts of aluminum hydroxide, 10 parts of aluminate, 10 parts of polyethylene glycol fatty acid ester, and use aluminate modifier Antimony and aluminum hydroxide are used for surface modification, and then the modified antimony trioxide, aluminum hydroxide and polyethylene glycol fatty acid ester organic dispersant are mixed in two stages at low speed and high speed, and then passed through a twin-screw extruder Extrude, granulate with a granulator, sieve with a sieving machine, and dry with a dryer to obtain the flame retardant masterbatch product. Among them: the modification temperature is 115°C, the stirring speed is 3000rpm, and the stirring time is 3h; the stirring speed of low-speed mixing is 1100rpm, the mixing time is 15min, and it is carried out at room temperature; the stirring speed of high-speed mixing is 3000rpm, the temperature is controlled at 80°C, and the mixing time is 30min.
Embodiment 2
[0022] Embodiment 2: Taking parts by weight as a unit, take 70 parts of antimony trioxide, 20 parts of aluminum hydroxide, 5 parts of silane, and 5 parts of polyethylene glycol fatty acid ester, and use a silane modifier to react antimony trioxide and hydrogen Aluminum oxide is surface modified, and then the modified antimony trioxide, aluminum hydroxide and polyethylene glycol fatty acid ester organic dispersant are mixed in two stages at low speed and high speed, and then extruded through a twin-screw extruder. Granulation by granulator, sieving by sieving machine, drying by dryer to obtain flame retardant masterbatch products. Among them: the modification temperature is 100°C, the stirring speed is 2000rpm, and the stirring time is 3.5h; the stirring speed of low-speed mixing is 500rpm, the mixing time is 20min, and it is carried out at room temperature; the stirring speed of high-speed mixing is 5000rpm, the temperature is controlled at 100°C, and the mixing time is 20min ...
Embodiment 3
[0023] Example 3: In parts by weight, weigh 60 parts of antimony trioxide, 25 parts of aluminum hydroxide, 3 parts of titanate, 4.5 parts of aluminate, 7.5 parts of polyethylene glycol fatty acid ester, and use titanate , aluminate modifier to modify the surface of antimony trioxide and aluminum hydroxide, and then carry out low-speed and high-speed two Grade mixing, then extruded by a twin-screw extruder, granulated by a granulator, sieved by a sieving machine, and dried by a dryer to obtain a flame retardant masterbatch product. Among them: the modification temperature is 130°C, the stirring speed is 4000rpm, and the stirring time is 2.5h; the stirring speed of low-speed mixing is 800rpm, the mixing time is 17.5min, and it is carried out at room temperature; the stirring speed of high-speed mixing is 4000rpm, the temperature is controlled at 90°C, and the mixing time is 25min.
