Problems solved by technology

[0010] In addition, there are still many institutions that focus on the research of PET / PE alloy compatibilizers. Many scientific research results of these institutions belong to the exploratory stage, and most of the PE used are original packaging materials (non-recycled), and there are no industrialized products. Of course there is no processed pipe product
[0011] In summary, the existing technology shows that many institutions only do research on PET / PE alloys or PET and PE compatibilizers; and these researches require drying of PET, and the mechanical properties of the obtained materials are generally , such as elongation at break, etc.
The mechanical properties are an important basis for measuring the quality of the material, which is directly related to the compatibilizer and preparation process for preparing PET / PE alloys, which shows that the prior art does not have a good solution to the compatibilizer and preparation process

Abstract

The invention relates to the field of material processing, in particular to a polyester polyethylene alloy plastic pipe and a preparation method thereof. The polyester polyethylene alloy plastic pipe is mainly prepared from the raw materials including PET (polyethylene terephthalate), PE (polyethylene), compatilizer and antioxygen, wherein the compatilizer is maleic anhydride grafted PE or maleic anhydride grafted POE (polyoxyethylene), and the antioxygen is antioxygen 1010 or antioxygen 1076. The problem that PET and PE are incompatible is well solved; the prepared polyester polyethylene alloy plastic pipe has higher mechanical property, and can meet the requirements in the fields of engineering embedded pipes, threading pipes and the like; moreover, the PET does not need to be dried in the preparation process, so that a great deal of manpower and material resources are saved. The preparation method is simple and practicable, and the prepared polyester polyethylene alloy plastic pipe has higher mechanical property; moreover, the polyester polyethylene alloy plastic pipe is used and continuously extruded, so that a fused mixture is prepared into the pipe, the material performance reduction can be decreased, and the energy of secondary heating can also be reduced.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a polyester polyethylene alloy plastic pipe and a preparation method thereof. Background technique [0002] PET plastic has a wide range of applications in the packaging field, whether it is packaging film, roll material, or beer bottles, PET plastic is used. But when these materials are discarded, they are faced with the problem of what to do with them. [0003] At the SPE Global Plastic Environment Conference (GPEC) held in Detroit, an alloy material made of polyethylene and recycled PET was introduced, which attracted attention. [0004] At present, EremaNorthAmerica is cooperating with three manufacturers in Europe, using Erema's Vacurema continuous curing reactor to heat and dry PET under vacuum to restore its intrinsic viscosity, and then use an exhaust with a crystallization dryer to Pneumatic twin-screw extruder extrusion pelletization. [0005] Spalex S.A., which ha...
