Recycle technology of plastic lunchboxes

Abstract

The invention discloses a recycle technology of plastic lunchboxes and belongs to the field of plastic. The recycle technology comprises the following steps: (1) collection and leaching; (2) crushing; (3) removal of impurities; (4) cracking: cleaned fine granules are put into a reaction pot and undergo hydrocracking at 800 DEG C in presence of an initiator and under the stirring condition for 50 min so as to obtain 80% of a micromolecular liquid, wherein the initiator is a mixture of ammonium persulfate and potassium persulphate; (5) joint recombination; (6) vacuum cleaning; and (7) drying and shaping. After a series of treatments of plastic lunchboxes, wastes are reutilized, the environment is purified, and pollution is reduced. The technology provided by the invention has a wide market application range.

Description

technical field [0001] The invention belongs to the field of plastics, and in particular relates to a recycling process for plastic lunch boxes. Background technique [0002] White pollution is an image term for the phenomenon of refractory plastic waste polluting the environment. It refers to the waste of various domestic plastic products made of polystyrene, polypropylene, polyvinyl chloride and other polymer compounds that are discarded after use. Solid waste is difficult to degrade due to random littering, resulting in serious pollution of the urban environment. Among them, with the rapid and simplified pace of life, many people are willing to use plastic lunch boxes for meals. Therefore, plastic lunch boxes have been Extensive use has become a part of white pollution that cannot be ignored. Chinese patent application number CN201310073598.2 discloses a recycling process for waste plastics, which includes the following steps: firstly classify and clean the recycled plast...

[0002] White pollution is an image term for the phenomenon of refractory plastic waste polluting the environment. It refers to the waste of various domestic plastic products made of polystyrene, polypropylene, polyvinyl chloride and other polymer compounds that are discarded after use. Solid waste is difficult to degrade due to random littering, resulting in serious pollution of the urban environment. Among them, with the rapid and simplified pace of life, many people are willing to use plastic lunch boxes for meals. Therefore, plastic lunch boxes have been Extensive use has become a part of white pollution that cannot be ignored. Chinese patent application number CN201310073598.2 discloses a recycling process for waste plastics, which includes the following steps: firstly classify and clean the recycled plastics, and remove Impurities; the cleaned plastic is cut into granular plastic granules by a cutting machine, and then the plastic granules, heat stabilizer and additives are evenly mixed in a mass ratio of 5:1:2: then the mixture is put into injection molding machine, and then heated to 180-220 degrees Celsius and kept for 30-45 minutes; finally, the finished product is obtained by injection molding or extrusion molding, the process is simple, the cost is low, and the plastic products recovered by this process have a long service life and a wide range of applications. Strong market competitiveness, but this method cannot recycle plastic lunch boxes in batches, the reuse rate is not high, and the operation control conditions are difficult
