Example Embodiment
[0023] Example 1: Masterbatch ingredients are shown in Table 1.
[0024]
[0025] 1) Under normal temperature and pressure, in the high-speed mixer, turn on the stirring blade and control the speed to 600r / min, and the heating and mixing temperature to be 85°C;
[0026] 2) After weighing the materials according to the ingredients list, put in 50% of the total amount of PET resin, and then put in the other components according to the proportion of ingredients. After the materials are mixed for 10 minutes, ensure that the slip agent has been completely melted and the materials are formed. Block, add the remaining PET resin after cooling;
[0027] 3) Then control the mixer speed to 480r / min to disperse the materials into granules to complete the preliminary melting and mixing of the materials, and the dispersing time is 1h;
[0028] 4) Put the preliminarily melted and mixed materials into the twin-screw machine for further melting and blending. The melting temperature is controlled at 26...

[0030] Example 2: See Table 2 for the ingredients of the masterbatch.
[0031]
[0032] 1) Under normal temperature and pressure, in the high-speed mixer, turn on the stirring paddle and control the speed to 1000r / min, and the heating and mixing temperature to be 100℃;
[0033] 2) After weighing the materials according to the ingredients list, first put in 50% of the total amount of PET resin, and then put in the other components according to the proportion of the ingredients, and wait for the materials to mix for 15 minutes to ensure that the slip agent has been completely melted and the materials are consolidated Block, add the remaining PET resin after cooling;
[0034] 3) Then control the mixer speed to be 250r / min to disperse the materials into granules to complete the preliminary melting and mixing of the materials, and the dispersing time is 10h;
[0035] 4) Put the preliminarily melted and mixed materials into the twin-screw machine for further melting and blending. The meltin...

[0037] Example 3: See Table 3 for the ingredients of the masterbatch.
[0038]
[0039] 1) Under normal temperature and pressure, in the high-speed mixer, turn on the stirring blade and control the speed to 800r / min, and the heating and mixing temperature to be 95℃;
[0040] 2) After weighing the materials according to the ingredients list, first put in 50% of the total amount of PET resin, and then put in other components according to the proportion of the ingredients, and wait for the materials to mix for 25 minutes to ensure that the slip agent has been completely melted and the materials are consolidated Block, add the remaining PET resin after cooling;
[0041] 3) Control the mixer speed to be 500r / min to disperse the materials into granules to complete the preliminary melting and mixing of the materials, the dispersing time is 5h;
[0042] 4) Put the preliminarily melted and mixed materials into the twin-screw machine for further melting and blending. The melting temperature is ...
