Problems solved by technology

[0004] The production method of plastic granules in the prior art is relatively complex, with low production efficiency and finished product qualification rate, high energy consumption, serious secondary pollution, generally poor toughness, and it will become brittle after being placed for a period of time, easy to crack, and unstable in quality. High cost, resulting in short service life; in the process of storage, processing and daily use, it will be easily aged and degraded by heat, light and oxygen, which seriously affects the service life of the product
In addition, even the current advanced sorting of waste plastics has an impurity level of more than 5%. The presence of impurities affects the compatibility of recycled plastics and will reduce the mechanical properties of the plastic particles produced.

Embodiment 1

[0033] A process for producing wear-resistant high-strength plastic particles using waste plastics, characterized in that it includes the following steps:

[0034] Step S1. Pretreatment of waste plastics: Break the collected waste plastic products into pieces with a maximum length of no more than 3cm, add the plastic pieces to boiling water and boil for 20 minutes, take out the plastic pieces after cooling, and then quickly and clean the plastic pieces Put it into a ball mill and mill it at 300r / min for 100min. After ball milling, add water 30 times the weight of the mixture to the mixture and stir evenly. Ultrasonic clean at 50°C for 20min. Then put it in a vacuum drying oven at 110°C and dry it to constant weight, and then crush it through a 20-mesh sieve to obtain waste plastic powder; the cleaning agent is made by mixing the following raw materials in parts by weight: dodecylbenzene 5 parts of sodium sulfonate, 10 parts of lecithin, 5 parts of fatty acid sorbitan, 30 parts o...

Embodiment 2

[0039] A process for producing wear-resistant high-strength plastic particles using waste plastics, characterized in that it includes the following steps:

[0040] Step S1. Pretreatment of waste plastics: Break the collected waste plastic products into pieces with a maximum length of no more than 3.5 cm, add the plastic pieces to boiling water and boil for 22 minutes, take out the plastic pieces after cooling, and put the plastic pieces together quickly Mix the cleaning agent, put it into a ball mill and mill it at a speed of 320r / min for 110min, add water 35 times the weight of the mixture to the mixture after ball milling, stir evenly, ultrasonically clean at 55°C for 22min, centrifuge after cleaning, take the sediment, and wash it with water , and then placed in a vacuum drying oven at 113°C to dry to constant weight, and then crushed through a 25-mesh sieve to obtain waste plastic powder; the cleaning agent is made by mixing the following raw materials in parts by weight: d...

Embodiment 3

[0045] A process for producing wear-resistant high-strength plastic particles using waste plastics, characterized in that it includes the following steps:

[0046] Step S1, pre-treatment of waste plastics: crush the collected waste plastic products into fragments with a maximum length of no more than 4cm, add the plastic fragments to boiling water and boil for 25 minutes, take out the plastic fragments after cooling, and then quickly and clean the plastic fragments Put it into a ball mill and mill at 350r / min for 115min. After ball milling, add water 40 times the weight of the mixture to the mixture and stir evenly. Ultrasonic clean at 60°C for 25min. After cleaning, centrifuge to take the precipitate and wash it with water. Then put it in a vacuum drying oven at 115°C and dry it to constant weight, and then crush it through a 30-mesh sieve to obtain waste plastic powder; the cleaning agent is made by mixing the following raw materials in parts by weight: dodecylbenzene 8 part...

Abstract

The invention discloses a method for producing wear-resistant high-strength plastic particles from waste plastic, which is characterized by comprising the following steps: S1, pretreatment of the waste plastic, S2, preparation of poly(allyl 3,5-diamino-1H-pyrazole-4-carboxylate 2,3,5,6-tetrafluoroterephthalic acid) amide, and S3, molding of the plastic particles. The invention also discloses the plastic particles produced by the method for producing the wear-resistant high-strength plastic particles by using the waste plastic. The plastic particles disclosed by the invention can realize resource recycling of waste plastic in an environment-friendly, safe, efficient and rapid manner, can change waste into valuables, is high in strength, excellent in wear resistance and good in weather resistance and performance stability, and has relatively high economic value, social value and ecological value.

Description

technical field [0001] The invention relates to the technical field of recycling waste plastics, in particular to a process for producing wear-resistant high-strength plastic particles by using waste plastics. Background technique [0002] At present, the rapid development of the plastics industry has brought many conveniences to people's lives, but at the same time it has also brought a series of social problems caused by waste plastics and waste plastics. The application of plastic products has penetrated into every corner of society, from industrial production to basic necessities of life, plastic products are everywhere. People have begun to find that plastic waste has quietly come to us, seriously affecting our health and living environment. For example, some agricultural lands have begun to reduce production due to the impact of abandoned mulch, and the "white pollution" caused by waste plastics has begun to cause headaches. , Lunch boxes that do not rot or decompose ...
