Drying-free extrusion technology of PET nano reinforced plate

Abstract

The invention discloses a drying-free extrusion technology of a PET nano reinforced plate, and the technology can substantially reduce residual quantity of water and low molecular leakage in a finished product. 0.5-1 wt.% of polymer processing auxiliary agent is added into a raw material, and water and low molecular leakage are discharged through an adsorption apparatus during an extrusion process. According to the invention, the raw material is added with the polymer processing auxiliary agent, and a drying of a fused raw material is omitted, so as to simplify the extrusion technology; besides, residual quantity of water and low molecular leakage in the PET nano reinforced plate finished product is reduced, so as to improve quality of the finished product and especially improve transparency substantially.

Description

technical field [0001] The invention relates to a PET nano-reinforced plate production line, in particular to the extrusion process of the PET nano-reinforced plate production line. Background technique [0002] At present, in the production line used to produce PET nano-reinforced sheets, a special drying system is installed on the extruder, which is used to dry raw materials in a molten state, which makes the extrusion process of PET nano-reinforced sheets more complicated, and , More water and low-molecular leakages remain in the formed PET nano-reinforced board, which affects the quality of the finished PET nano-reinforced board, especially the transparency of the finished PET nano-reinforced board. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a drying-free extrusion process for PET nano-reinforced boards that can greatly reduce the residual amount of water and low-molecular leakage in the finished product...
