Embodiment 1
[0070] Step 1: Take 20 kg of titanium dioxide 104 (the diameter of the primary particle is 0.2-0.5 microns) and put it into a banburying container, add 0.9 kg of Hi Former fluoroelastomer (CLARINT) while stirring, mix for 15 minutes, and then add 20 Kilogram linear low density polyethylene (LLDPE, the melt index under 2.16kg, 190 ℃ of conditions is 20g / 10min), keep 100 ℃ banburying for 30 minutes, obtain pre-dispersion;
[0071] Step 2: Granulate the pre-dispersion prepared by banburying on a twin-screw granulator, and set the temperature at 140-220 degrees Celsius;
[0072] Step 3: Add 10.33 kg of low-density polyethylene (LDPE) and 0.966 kg of high-density polyethylene (HDPE) to the masterbatch obtained in step (2), mix well and perform secondary granulation, and set the temperature at 140- 220 degrees Celsius to get the required white mother.
Embodiment 2
[0074] Step 1: Take 33 kg of titanium dioxide 104 (the diameter of the primary particle is 0.2-0.5 microns) into the banburying container, add 1.1 kg of Hi Former fluoroelastomer (CLARINT) while stirring, mix for 15 minutes, and then add 7.3 Kilogram of LLDPE (melt index under 2.16kg, 190 DEG C is 20g / 10min), keep banburying at 100 DEG C for 30 minutes to obtain pre-dispersion;
[0075] Step 2: Granulate the pre-dispersion prepared by banburying on a twin-screw granulator, and set the temperature at 140-220 degrees Celsius;
[0076] Step 3: Add 4.33 kg of LDPE and 1.96 kg of HDPE to the masterbatch obtained in step (2), mix evenly and carry out secondary granulation, and set the temperature at 140-220 degrees Celsius to obtain the required white masterbatch.
Embodiment 3
[0078]Step 1: Take 8.26 kg of titanium dioxide 104 (the diameter of the primary particle is 0.2-0.5 microns) into the banburying container, add 0.3 kg of Hi Former fluoroelastomer (CLARINT) while stirring, mix for 10 minutes, and then add 8 Kilogram of LLDPE (melt index under 2.16kg, 190°C is 20g / 10min), kept banburying at 100°C for 10 minutes to obtain pre-dispersion;
[0079] Step 2: Granulate the pre-dispersion prepared by banburying on a twin-screw granulator, and set the temperature at 140-220 degrees Celsius;
[0080] Step 3: Add 2 kg of LDPE and 1.5 kg of HDPE to the masterbatch obtained in step (2), mix evenly and carry out secondary granulation, and set the temperature at 140-220 degrees Celsius to obtain the required white masterbatch.
