Abstract

The invention relates to the technical field of plastic products, in particular to a technology and device for preparing a plastic barrel through reprocessed plastics. The technology comprises the following steps that firstly, waste plastics are washed through water and dried and are shorn into strips, ethyl alcohol, acetone and deionized water are sequentially used for conducting ultrasonic filtering and cleaning in an ultrasonic machine, then 120# gasoline and deionized water are used for sequentially conducting two-time cleaning, drying is conducted till the water content is lower than 1 wt%, and the clean waste plastic strips are obtained; secondly, fusion modification is conducted; thirdly, vacuum defoaming is conducted; and fourthly, injection molding is conducted. According to the technology for preparing the plastic barrel through the reprocessed plastics, waste is utilized, influences on the surrounding environment can be reduced, the machining technology is simple and convenient to conduct, the requirement for mechanical equipment is not high, cost is low, and good economic benefits are achieved. The device used in the technology for preparing the plastic barrel through the reprocessed plastics is simple in structure, reasonable in design, small in occupied area, long in service life and convenient to mount and dismount, and the usage process is safe and environment-friendly.

Description
