preparation example Construction

[0027] The preparation of the polyester carrier of the present application, taking PET as an example, preferably produces bishydroxyethyl terephthalate through esterification or transesterification of terephthalic acid or dimethyl terephthalate and ethylene glycol, by It is industrially produced by a polycondensation method in which a catalyst is used for polycondensation under high temperature and vacuum. In a specific embodiment, terephthalic acid, ethylene glycol, cyclohexanedimethanol, catalyst and heat stabilizer can be used as raw materials for esterification; or terephthalic acid, ethylene glycol, isophthalic acid , catalyst and heat stabilizer as raw materials for esterification. In another specific embodiment, the catalyst is any compound of Ti / Si non-heavy metal catalyst and antimony trioxide, and the added amount thereof is 0.01-0.09% of the weight of the polyester. In another specific embodiment, the heat stabilizer is a phosphoric acid compound, and its addition ...

Abstract

This application discloses a functional masterbatch production system for polyester film, which includes a polyester carrier preparation mechanism and a functional material preparation mechanism. The polyester carrier preparation mechanism includes at least one esterification reactor and at least one polycondensation reactor. The functional material slices prepared by the material preparation mechanism are added to the polycondensation reactor of the polyester carrier preparation mechanism, and then the functional masterbatch of the present application is prepared. Based on the existing polyester preparation mechanism, the functional masterbatch production system of this application integrates the functional material preparation mechanism and supporting equipment such as extrusion, slicing, drying and connecting pipelines, which can be used for continuous and efficient production of the present application. Functional masterbatch. The polyester film added with the functional masterbatch of the present invention can be used in application fields such as glass, building materials, printing, medicine and hygiene, optics, and packaging.

Description

technical field [0001] The present application relates to a production system for functional additives for polyester films, and the functional additives are functional masterbatches prepared in chip form. In particular, the present application relates to a functional masterbatch production system for polyester films. The polyester film added with the functional masterbatch of the present invention can be used in application fields such as glass, building materials, printing, medicine and hygiene, optics, and packaging. Background technique [0002] Polyester is a general term for polymers obtained by polycondensation of polyols and polyacids. There are many kinds of polyester, the public is more familiar with PET (polyethylene terephthalate), PBT (polybutylene terephthalate), PTT (polytrimethylene terephthalate), PCT ( Polyester-1,4-cyclohexanedimethanol, etc. Polyester, especially polyester film represented by PET, is usually made of polyethylene terephthalate by extrusio...
