Embodiment 1

[0026] Pour 100 parts of recycled polypropylene, 10 parts of recycled polyethylene, 1 part of 2-ethylhexyl diphenyl phosphate, 0.1 part of antioxidant 1010, and 0.1 part of antioxidant 168 into a high-speed mixer according to parts by weight. The temperature is controlled at 20°C, the rotation speed is 1000r / min, and the mixing time is 3min; after turning on the mixer, add 0.5 parts of white oil, and mix again, the rotation speed is 300r / min, and the mixing time is 1min, so that it is fully uniform and the mixed material is obtained;

[0027] Feed the mixed material into the twin-screw extruder through the main feeding port, add 10 parts of glass fiber through the side feeding port, extrude, water-cool, pelletize and dry to obtain the recycled polyolefin plastic composition. Among them, the temperature of the twin-screw extruder is set as: 140°C in zone 1, 150°C in zone 2, 185°C in zone 3, 200°C in zone 4, 190°C in zone 5, 190°C in zone 6, and the rotation speed is 500 rpm.

Embodiment 2

[0029] Pour 100 parts of recycled polypropylene, 30 parts of recycled polyethylene, 5 parts of 2-ethylhexyl diphenyl phosphate, 0.2 part of antioxidant 1010, and 0.5 part of antioxidant 168 into a high-speed mixer according to parts by weight. The temperature is controlled at 40°C, the speed is 2000r / min, and the mixing time is 5 minutes; after turning on the mixer, add 2 parts of white oil, and mix again, the speed is 500r / min, and the mixing time is 2 minutes, so that it is fully uniform and the mixed material is obtained;

[0030] Feed the mixed material into the twin-screw extruder through the main feeding port, add 18 parts of glass fiber through the side feeding port, extrude, water-cool, pelletize and dry to obtain the recycled polyolefin plastic composition. Wherein the twin-screw extruder temperature is set as: zone 1 150°C, zone 2 160°C, zone 3 195°C, zone 4 210°C, zone 5 195°C, zone 6 200°C, and the speed is 1000 rpm.

Embodiment 3

[0032] Pour 100 parts of regenerated polypropylene, 50 parts of regenerated polyethylene, 3 parts of 2-ethylhexyl diphenyl phosphate, 0.4 part of antioxidant 1010, and 0.2 part of antioxidant 168 into a high-speed mixer according to parts by weight. The temperature is controlled at 30°C, the rotation speed is 1500r / min, and the mixing time is 4min; after turning on the mixer, add 1 part of white oil, and mix again, the rotation speed is 400r / min, and the mixing time is 1min, so that it is fully uniform and the mixed material is obtained;

[0033] Feed the mixed material into the twin-screw extruder through the main feeding port, add 30 parts of glass fiber through the side feeding port, extrude, water-cool, pelletize and dry to obtain the recycled polyolefin plastic composition. Among them, the temperature of the twin-screw extruder is set as: 145°C in the first zone, 155°C in the second zone, 190°C in the third zone, 205°C in the fourth zone, 190°C in the fifth zone, 195°C in ...

Abstract

The invention discloses a regenerated polyolefin plastic composition as well as a preparation method and application thereof. The regenerated polyolefin plastic composition is prepared from the following components in parts by weight: 100 parts of regenerated polypropylene, 10-100 parts of regenerated polyethylene, 10-30 parts of glass fiber, 1-5 parts of 2-ethylhexyl diphenyl phosphate, 0.1-0.5 part of antioxidant 1010, 0.1-0.5 part of antioxidant 168 and 0.5-2 part of lubricant. The regenerated polyolefin composition solves the problems of poor toughness, low strength and poor stability of the waste polyolefin material, has excellent toughness and strength, changes wastes into valuables and saves a cost.

Description

technical field [0001] The invention belongs to the field of engineering plastics, and in particular relates to a recycled polyolefin plastic composition and a preparation method and application thereof. Background technique [0002] In recent years, with the continuous improvement of polymer synthesis technology, the plastic industry has developed rapidly, and more and more plastic products have entered our field of vision and become an indispensable substance in people's lives. But at the same time, it has also brought us a great negative impact. The amount of discarded plastics has increased sharply, white pollution, urban garbage mines, etc. continue to appear in our lives. The recycling of waste plastics has always been an important part of the development of circular economy, and it is also an important way to achieve sustainable development advocated by the state. [0003] At present, waste plastics have been used to a certain extent, but according to relevant report...
