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.
