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

Abstract

The invention provides a method for processing PET / PA ferrous alloy color masterbatch by chemically depolymerizing waste polyester textiles. The method is characterized by comprising the following steps: preparing components including, by weight, 20 parts of PET, 40 parts of blown-film-grade LDPE, 30 parts of black carbon black and 10 parts of a compatibilizer; uniformly mixing the prepared components; and performing extrusion and granulation so as to obtain PET / LDPE ferrous alloy blown-film-type color masterbatch. Or the method comprises the following steps: preparing components including, by weight, 30 parts of PET, 30 parts of extrusion-grade LLDPE, 30 parts of black carbon black and 10 parts of a compatibilizer; uniformly mixing the prepared components; and performing extrusion and granulation so as to obtain PET / LLDPE ferrous alloy extrusion-type color masterbatch. Or the method comprises the following steps: preparing components including, by weight, 40 parts of PET, 20 parts of injection-grade HDPE, 30 parts of black carbon black and 10 parts of a compatibilizer; uniformly mixing the prepared components; and performing extrusion and granulation so as to obtain PET / HDPE ferrous alloy injection-type color masterbatch.

Description

technical field [0001] The invention discloses a method for chemically depolymerizing polyester waste textiles and processing PET / PE 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 process PET / PE black alloy color masterbatch by chemical...
