Problems solved by technology

[0003] As we all know, except for a very small amount of existing waste textiles that are used by people using physical methods, they can neither be reused nor directly reprocessed after recycling, and can only be used as landfills or incinerated.
Not only waste land resources but also cause secondary pollution

Embodiment 1

[0009] A kind of chemical depolymerization of polyester waste and old textiles according to the present invention, the method for processing PET / PP black alloy color masterbatch, implements according to following process procedure:

[0010] Depolymerize polyester waste textiles with glycerin residue heated to 260-280 degrees, and filter the dregs in the solution to obtain liquid PET. Prepare PET / PP blown film type black alloy masterbatch according to the following parts by weight.

[0011] PET 20 copies

[0012] Blown film grade PP 40 parts

[0013] Black carbon black 30 parts

[0014] Compatibilizer 10 parts

[0015] Test results

[0016]

[0017] Mix the above prepared components and parts by weight, extrude and granulate, and obtain PET and PP black alloy blown film type

[0018] Masterbatch.

Embodiment 2

[0020] With reference to the method of Example 1, each component and parts by weight were prepared in the following proportions to prepare a PET / PP drawing-type black masterbatch.

Abstract

The invention discloses a method for chemically depolymerizing polyester waste textiles to produce PET / PP black alloy color master batches. The method comprises the following steps: heated glycerin residues with a temperature of 260-280 DEG C are used to depolymerize the polyester waste textiles, dregs in the obtained solution are filtered out completely, black carbon black, a compatilizer and a PP raw material for film blowing, wire drawing and injection molding of different models are added, and the obtained mixture is uniformly mixed, and undergoes extruding granulation to obtain the special PET and PP black alloy color master batches for film blowing, wire drawing and injection molding.

Description

technical field [0001] The invention discloses a method for chemically depolymerizing polyester waste textiles and processing PET / PP black alloy masterbatch. [0002] technical background [0003] As we all know, except for a very small amount of existing waste textiles that are used by people using physical methods, they can neither be reused nor directly reprocessed after recycling, and can only be landfilled or incinerated. Not only wasting land resources but also causing secondary pollution. Contents of the invention [0004] The purpose of the present invention is in order to overcome the defective of above-mentioned background technology, fundamentally completely eliminates this backward treatment mode, completely solves the second pollution. [0005] In order to achieve the above object, the technical solution of the present invention is as follows: [0006] The invention discloses a method for our factory to produce PET / PP black alloy color masterbatch by chemical...
