Embodiment 1

[0029] Electrostatically separate the recovered plastic waste from different materials to ensure the purity of the recycled materials; pour 88.2 parts of PP recycled gray-white washing machine nozzle material into the high-speed mixing equipment, add auxiliary materials and fillers in turn, 10.3 parts of 2000 mesh talcum powder, anti- Oxygen agent 264 and antioxidant 168 are mixed in equal proportions, 0.5 parts; anti-ultraviolet agent, anti-UV agent (770) and light stabilizer (744), are mixed in equal proportions, 0.7 parts; colorant, titanium yellow and iron red are used , Titanium dioxide according to the ratio of 1:1:1 formula material 0.3 parts. After the high-speed stirring is completed, the stirred material is sent to a high-temperature extruder for high-temperature extrusion. Before the stirred material is sent into the high-temperature extruder, the temperature of the extruder is raised to the set process temperature of 150-200°C. The material extruded at high temper...

Embodiment 2

[0031] Electrostatically separate the recovered plastic waste from different materials to ensure the purity of the recycled materials; pour 86.8 parts of PP recycled gray-white washing machine nozzle material into the high-speed mixing equipment, and add 12.0 parts of auxiliary fillers in sequence, including talcum powder and white carbon Black and calcium powder are proportioned in equal proportions; 0.6 parts of antioxidant 1010 and antioxidant 264 are proportioned in equal proportions; 0.5 parts of anti-UV agent (770) is used as anti-ultraviolet agent; 0.1 part of titanium dioxide is used as coloring agent. After the high-speed stirring is completed, the stirred material is sent to a high-temperature extruder for high-temperature extrusion. Before the stirred material is sent into the high-temperature extruder, the temperature of the extruder is raised to the set process temperature of 150-200°C. The material extruded at high temperature is directly cooled by water, cut int...

Embodiment 3

[0033] Electrostatically separate the recovered plastic waste from different materials to ensure the purity of the recycled materials; pour 85.2 parts of recycled gray-white washing machine nozzle material from PP into the high-speed mixing equipment, add auxiliary fillers in turn, 13.4 parts of 2000 mesh talcum powder, anti- Oxygen 1010 and antioxidant 168 are proportioned in equal proportions of 0.6 parts, anti-ultraviolet agent is anti-UV agent (770), 0.7 parts, coloring agent, and titanium yellow, iron red and titanium dioxide are used in proportions of 0.1 parts, and high-speed stirring is completed Finally, the stirred material is sent to a high-temperature extruder for high-temperature extrusion. Before the stirred material is sent into the high-temperature extruder, the temperature of the extruder is raised to the set process temperature of 150-200°C. The material extruded at high temperature is directly cooled by water, cut into pellets, and dried and packaged.

Abstract

The invention discloses high-aging-resistance PP resin prepared by reclaimed materials and a preparation method of the high-aging-resistance PP resin. The high-aging-resistance PP resin is prepared by, by weight percentage, 80-92% of PP reclaimed greyish white washing machine drainage opening material serving as the main material, 5-17% of filling agent, 0.1-1.0% of antioxidant, 0.1-1% of anti-ultraviolet agent and 0.01-0.5% of coloring agent. The prepared PP resin is high in aging resistance and simple in preparation process, and downstream products prepared by the high-aging-resistance PP resin is good in aging resistance, low in production cost, high in strength and excellent in comprehensive performance.

Description

technical field [0001] The invention belongs to the technical field of recycling and utilization of waste plastics, in particular, the invention relates to a PP resin with strong aging resistance and a preparation method thereof Background technique [0002] From the beginning of the last century, people began to develop a new type of material to replace steel, which ushered in the birth of plastic materials. With the establishment of plastic material companies such as Taiwan Chemical Fiber and Chi Mei Industrial, more and more plastic products have entered our daily life, and many steel products in home appliances and automobiles have been replaced by plastic materials. [0003] After more than half a century of development and the widespread use of plastic products, more and more plastic waste can be seen everywhere in our daily life. With the improvement of people's living standards, the amount of various plastics is gradually increasing. In order to save energy and p...
