Embodiment 1

[0008] The method for preparing PBT raw material by chemical reduction of PET waste bottle material described in the present invention firstly crushes PET waste bottle material into small fragments, and melts it with butanediol heated at 220°C.

Embodiment 2

[0010] On the basis of Example 1, the dregs in the dissolved liquid were filtered clean.

Embodiment 3

[0012] On the basis of Example 2, the solution obtained by filtering the dregs is more finely filtered with carbon powder, and the pigment etc. in the solution are filtered out.

Abstract

The invention provides a method for preparing a PBT raw material by chemical reduction of a PET waste bottle material. The method comprises the following steps: heating and melting the PET waste bottle material by using butanediol, performing filtration, performing decolorization, performing purification, adding a catalyst, and performing polymerization to form PBT.

Description

technical field [0001] The invention discloses a method for preparing PBT raw materials by using chemical reduction to use waste PET bottle materials in our factory. [0002] technical background [0003] As we all know, the existing waste PET bottle materials are generally utilized by people through physical granulation regeneration. There are no other high-value applications. Contents of the invention [0004] The purpose of the present invention is in order to overcome the defect of above-mentioned background technology, fundamentally eliminate this backward processing way completely. In order to achieve the above object, the technical solution of the present invention is as follows: [0005] The present invention heats and melts waste PET bottle material with butanediol, decolorizes and purifies after filtration, and adds a catalyst to polymerize it into PBT. detailed description [0006] The method for preparing PBT raw material by chemical reduction of PET waste ...
