Embodiment 1

[0026] According to the weight of the recycled polypropylene 100 parts, recycled polyethylene 10 parts, 2-ethylhexyl diphenyl phosphate 1 part, antioxidant 1010 0.1 parts, antioxidant 168 0.1 parts into the high-speed mixer mixing, the temperature control at 20 °C, speed 1000r / min, mixing time 3min; after opening the mixer add 0.5 parts of white oil, mix again, speed 300r / min, mixing time 1min, so that it is fully uniform, to obtain mixed materials;

[0027]The mixed material is fed into a twin screw extruder through the main feeding port, and 10 parts of glass fiber are added through the side feeding port, extruded, water-cooled, pelletized and dried, that is, the regenerated polyolefin plastic composition is prepared. Among them, the temperature of the twin screw extruder is set to: 140 °C in the first zone, 150 °C in the second zone, 185 °C in the third zone, 200 °C in the fourth zone, 190 °C in the fifth zone, 190 °C in the sixth zone, and the speed is 500 rpm.

Embodiment 2

[0029] According to the weight of the recycled polypropylene 100 parts, recycled polyethylene 30 parts, 2-ethylhexyl diphenyl phosphate 5 parts, antioxidant 1010 0.2 parts, antioxidant 168 0.5 parts into the high-speed mixer mixing, the temperature control at 40 °C, speed 2000r / min, mixing time 5min; after opening the mixer, add 2 parts of white oil, mix again, speed 500r / min, mixing time 2min, so that it is fully uniform, to obtain mixed materials;

[0030] The mixed material is fed into a twin screw extruder through the main feeding port, and 18 parts of glass fiber are added through the side feeding port, extruded, water-cooled, granulated and dried, that is, the regenerated polyolefin plastic composition is prepared. Among them, the temperature of the twin screw extruder is set to: 150 °C in the first zone, 160 °C in the second zone, 195 °C in the third zone, 210 °C in the fourth zone, 195 °C in the fifth zone, 200 °C in the sixth zone, and the speed is 1000 rpm.

Embodiment 3

[0032] According to the weight of the recycled polypropylene 100 parts, recycled polyethylene 50 parts, 2-ethylhexyl diphenyl phosphate 3 parts, antioxidant 1010 0.4 parts, antioxidant 168 0.2 parts into the high-speed mixer mixing, the temperature control at 30 °C, speed 1500r / min, mixing time 4min; after opening the mixer, add 1 part of white oil, mix again, speed 400r / min, mixing time 1min, so that it is fully uniform, to obtain mixed materials;

[0033] The mixed material is fed into a twin screw extruder through the main feeding port, 30 parts of glass fiber is added through the side feeding mouth, extruded, water-cooled, pelletized and dried, that is, the regenerated polyolefin plastic composition is prepared. Among them, the temperature of the twin screw extruder is set to: 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 the sixth zone, and the speed is 800 rpm.

Abstract

The invention discloses a regenerated polyolefin plastic composition and its preparation method and application, which comprises 100 parts of regenerated polypropylene, 10-100 parts of regenerated polyethylene, 10-30 parts of glass fiber, 1~5 parts of phosphate ester, 0.1~0.5 parts of antioxidant 1010, 0.1~0.5 parts of antioxidant 168 and 0.5~2 parts of lubricant are prepared according to the parts by weight. The recycled polyolefin combination in the present invention The product solves the problems of poor toughness, low strength, and poor stability of waste polyolefin materials. The recycled polyolefin in the invention has excellent toughness and strength, and at the same time realizes turning waste into treasure and saving costs.

Description

Technical field [0001] The present invention belongs to the field of engineering plastics, specifically relates to a recycled polyolefin plastic composition and preparation method and application thereof. Background [0002] In recent years, with the continuous progress of polymer synthesis technology, the plastics industry has developed rapidly, and more and more plastic products have entered our vision and become indispensable substances for people's lives. But at the same time, it has also brought us a great negative impact, the amount of waste plastic 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 applied to a certain extent, but according to relevant reports, about 1400T of waste plas...
