Abstract

The present invention discloses a PET colour mother material, its preparation method and application. It contains PET and pigment, grain size of the pigment is 10-1000 nano, in the colour mother material 10%-80% of pigment can be contained, said pigment can be organic pigment or inorganic pigment whose heat-resisting temperature is above 300 deg.C, said pigment can be dispersed in PET in the form of granules. Besides, said invention also provides the concrete steps of its preparation method.

Description

technical field [0001] The invention relates to a PET color masterbatch and its manufacturing method and application. Background technique [0002] PET (polyethylene terephthalate) is a thermoplastic saturated polyester resin made from terephthalic acid or dimethyl terephthalate and ethylene glycol by direct polycondensation and transesterification. PET can be used for drawing fibers, extruding and biaxially stretching films and sheets, blow molding beverage bottles, reinforced and alloyed products for mechanical and electronic parts, etc. [0003] The color masterbatch is composed of organic pigments, additives, and resin as a carrier, mixed at the melting temperature, and mixed radially and axially through an extruder, so that the pigment particles are evenly distributed in the carrier, extruded, pelletized Pigment concentrate colorants or preparations are produced. At present, various color masterbatch products for injection molding, blown film, fiber and multi-function...
