preparation example Construction

[0034] A preparation method of high-performance antistatic PP-PE composite material, comprising the following steps:

[0035] 1) Weigh 80-100 parts of PP, 40-60 parts of PE, 0.1-0.3 parts of PP-g-MAH, 0.1-0.5 parts of NA-11, 6-12 parts of fullerene and 0.1 parts -0.5 parts of antioxidants are mixed and stirred evenly to obtain a mixture;

[0036] 2) Add the mixture obtained in step 1) from the main feeder of the extruder, and add 6-10 parts of carbon fiber separately from the side feeder to extrude and granulate to obtain an antistatic PP-PE composite material.

[0037] The extruder in step 2) is a twin-screw extruder, and the twin-screw extruder includes six temperature zones arranged in sequence, the temperature in the first zone is 150-170°C, the temperature in the second zone is 190-220°C, The temperature of the third zone is 190-220°C, the temperature of the fourth zone is 190-220°C, the temperature of the fifth zone is 190-220°C, the temperature of the sixth zone is 190...

Embodiment 1

[0039] 1) Weigh 80 parts of PP, 40 parts of PE, 0.1 part of PP-g-MAH, 0.1 part of NA-11, 6 parts of fullerene, 0.1 part of Irganox168, mix and stir evenly to obtain a mixture;

[0040] 2) Add the mixture obtained in step 1) from the main feeder of the extruder, and add 6 parts of carbon fiber separately from the side feeder to extrude and pelletize to obtain PP-PE composite material P1.

[0041] Among them, the temperature and screw speed of each zone of the twin-screw extruder are respectively: the temperature of the first zone is 150°C, the temperature of the second zone is 190°C, the temperature of the third zone is 190°C, the temperature of the fourth zone is 190°C, the temperature of the fifth zone is 190°C, and the temperature of the sixth zone is 190°C. The head temperature is 190°C, and the screw speed is 200r / min.

Embodiment 2

[0043] 1) Weigh 100 parts of PP, 60 parts of PE, 0.3 part of PP-g-MAH, 0.5 part of NA-11, 12 parts of fullerene, 0.1 part of Irganox168, 0.2 part of Irganox1010, 0.2 part of Irganox1330 and mix them evenly to obtain a mixed material;

[0044] 2) Add the mixture obtained in step 1) from the main feeder of the extruder, and 8 parts of carbon fiber are added separately from the side feeder to extrude and granulate to obtain PP-PE composite material P2.

[0045] Among them, the temperature and screw speed of each zone of the twin-screw extruder are: the temperature of the first zone is 170°C, the temperature of the second zone is 220°C, the temperature of the third zone is 220°C, the temperature of the fourth zone is 220°C, the temperature of the fifth zone is 220°C, and the temperature of the sixth zone is 220°C. The head temperature is 220°C, and the screw speed is 280r / min.

Abstract

The invention relates to a high-performance anti-static PP (polypropylene)-PE (polyethylene) composite material and a preparation method thereof. The high-performance anti-static PP-PE composite material consists of the following components in parts by weight: 80 to 100 parts of PP, 40 to 60 parts of PE, 6 to 12 parts of fullerene, 6 to 10 parts of carbon fibers, 0.1 to 0.3 part of a compatilizer, 0.1 to 0.5 part of a nucleating agent and 0.1 to 0.5 part of an antioxidant. The fullerene is added, so the anti-static performance of the PP-PE composite material is improved, and the high-performance anti-static PP-PE composite material has more excellent anti-static property compared with other anti-static fillers; the nucleating agent NA-11 is added, so that heterogeneous nucleation of the PP composite material is promoted and the physical performance of the material is improved; and the carbon fibers have the characteristics of high strength and high modulus, and the PP-PE composite material is filled with the carbon fibers, so that the strength and the modulus of the PP-PE composite material are improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a high-performance antistatic PP-PE composite material and a preparation method thereof. Background technique [0002] Polypropylene (PP) is an important thermoplastic polymer, which has low density, low water absorption, oil resistance and chemical resistance, and has become one of the most widely used plastics in modern times.
