A difficult combustibility plastic material and method the same using scrapped material

摘要

The present invention is directed to a flame-retardant molding material using polyethylene terephthalate (PET) and polyester as waste materials and a method for producing the same.;In the present invention, a flame retardant molding material and a method for producing the same are presented by mixing a PET container used and discarded with a waste of polyester generated in a large amount during molding and adding a flame retardant material.;A process of pulverizing the waste PET container and polyester, first drying the pulverized raw material, mixing the raw material and the flame retardant material, and melting the mixed PET, polyester and flame retardant material And a step of cooling the stand by cooling in a molten state, cutting into pellets of a predetermined size, selecting only pellets of uniform size, and drying the sorted pellets secondly; It is a method of manufacturing a flame-retardant molding material comprising a step of packaging.;Since the product manufactured by the manufacturing method of the present invention is a flame retardant molding material which is a raw material of injection molding by using a flame retardant material mixed with waste material or waste PET and polyester, it can be usefully applied to a building material requiring a flame retardant material. have.
