Pesticide plastic bottle recycling method, agricultural plastic product and rice seeding tray

Abstract

The invention provides a pesticide plastic bottle recycling method, an agricultural plastic product and a rice seeding tray. The pesticide plastic bottle recycling method comprises the following steps of: heating a recycled pesticide plastic bottle, rubbing to remove a label and / or aluminium foil on the surface of the pesticide plastic bottle; smashing the pesticide plastic bottle with the label and / or aluminium foil removed, carrying out chemical cleaning, drying, adding flexibilizer and tackifier and mixing to obtain mixture; and extruding and pelleting the mixture to obtain plastic particles. The invention also relates to an agricultural plastic product prepared by utilizing the plastic particles prepared by the pesticide plastic bottle recycling method by virtue of extruding and / or compression moulding. The pesticide plastic bottle recycling method provided by the invention has simple process and is economic and environmentally friendly, and recycling of resource is realized. The agricultural plastic product prepared by the plastic particles prepared by adopting the method provided by the invention is safe and environmentally friendly, no pesticide residue is kept, and the agricultural plastic product has high shock resistance, is endurable and has low production cost.

Description

technical field [0001] The invention belongs to the technical field of engineering plastics, and in particular relates to a method for recycling plastic pesticide bottles, agricultural plastic products and seedling trays. Background technique [0002] China is a country with a large population and a large agricultural country. Along with the large-scale use of pesticides and the substantial increase in the output of agricultural products, a large number of discarded pesticide bottles in fields and lakes have also caused serious pollution to the environment, and are constantly accumulating and expanding. . [0003] Since the 1990s, my country's pesticide packaging has quickly replaced glass with plastic. So far, it is estimated that the annual pesticide packaging waste generated in the country is about 150,000 to 200,000 tons, of which about 130,000 tons It is a plastic packaging bottle (PET material is about 100,000 tons or more). At present, there is basically no recycling...

AI Technical Summary

Problems solved by technology

Abandoned pesticide packaging bottles have become a major "persistent disease" leading to environmental pollution. It is difficult to recycle, labels and aluminum films are difficult to clean, the follow-up processing process is complicated, the processing cost is high, and the investment is large. For the second pollution, there has been no effective recycling and utilization by enterprises. At present, there is no complete and feasible recycling and reuse method.
