Embodiment 1
[0014] A PET film whose surface is easy to separate. The raw material composition of the film is as follows: 0.5% micropowder silicon, particle size 10-15μm, 1% micropowder silicon dioxide, particle size 100μm, 1% polyethylene wax, 0.5% Catalyst, wherein the catalyst is antimony dioxide in the antimony series catalyst, and the rest are PET pellets; it is produced according to the following production process:
[0015] A) Blend silicon, silicon dioxide, organic wax and catalyst in a granulator, grind and granulate to make a lubricant;
[0016] B) The lubricant prepared in step A) is mixed with PET pellets, stirred evenly, and then sent to the crystallization tower for crystallization. The crystallization temperature is 160°C, and the crystallization time is 5 hours; then sent to the drying cylinder for drying treatment, the drying temperature 160°C, drying time is 7 hours;
[0017] C) The dried material is transported into the extruder, mixed and plasticized, extruded and form...
Embodiment 2
[0020] The proportion of PET film is as follows: 1% micropowder silicon, particle size 10-15μm, 2% micropowder silicon dioxide, particle size 100μm, 2% polyethylene wax, 1% catalyst, wherein the catalyst is the wax in the antimony series catalyst Antimony acid, the rest are PET pellets; produce according to the following production process:
[0021] A) Blend silicon, silicon dioxide, organic wax and catalyst in a granulator, grind and granulate to make a lubricant;
[0022] B) The lubricant prepared in step A) is mixed with PET pellets, stirred evenly, and then sent to the crystallization tower for crystallization. The crystallization temperature is 150°C, and the crystallization time is 4 hours; then sent to the drying cylinder for drying treatment, the drying temperature 170°C, drying time is 6 hours;
[0023] C) The dried material is transported into the extruder, mixed and plasticized, extruded and formed into a PET film through a die. The extrusion channel of the extrude...
Embodiment 3
[0026] The proportion of PET film is as follows: 0.8% micro-powdered silicon, particle size 10-15 μm, 1.5% micro-powdered silicon dioxide, particle size 100 μm, 1.2% polyethylene wax, 0.8% catalyst, wherein the mass ratio of catalyst is 1:1 antimony trioxide and antimony cerate, and the rest are PET pellets; the production process is as follows:
[0027] A) Blend silicon, silicon dioxide, organic wax and catalyst in a granulator, grind and granulate to make a lubricant;
[0028] B) The lubricant prepared in step A) is mixed with PET pellets, stirred evenly, and then sent to the crystallization tower for crystallization. The crystallization temperature is 158°C, and the crystallization time is 5 hours; then sent to the drying cylinder for drying treatment, the drying temperature 165°C, drying time is 7 hours;
[0029] C) The dried material is transported into the extruder, mixed and plasticized, extruded and formed into a PET film through a die. The extrusion channel of the ex...
