Abstract

The invention relates to a polycarbonate high polymer material and a preparation method thereof, belonging to the field of high polymer materials. The polycarbonate high polymer material comprises 14 to 30 parts of polycarbonate, 5 to 10 parts of polyethylene terephthalate, 3 to 7 parts of cyclomethicone, 4 to 10 parts of polyvinyl alcohol phosphate, 3 to 9 parts of tetrabutyl titanate, 4 to 10 parts of polyethylene, 5 to 12 parts of polytrifluorochloroethene, 2 to 5 parts of glass fiber and 3 to 7 parts of silica. The preparation method comprises the following steps: (1) mixing the above-mentioned components; and (2) cooling the obtained mixture, subjecting the mixture to fusion extrusion with a double screw extruder and carrying out granulation with a granulator after extrusion so as to obtain the polycarbonate high polymer material.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a polycarbonate polymer material and a preparation method thereof. Background technique [0002] Polycarbonate (referred to as PC) is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Among them, the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates limit their application in engineering plastics. At present, only aromatic polycarbonate has been produced industrially. Due to the special structure of polycarbonate, it has become the fastest-growing general-purpose engineering plastic among the five major engineering plastics. Carbonate is non-crystalline engineering plastic, odorless, tasteless, non-toxic, transparent amorphous plastic. It has the characteristics of excellent strength and toughness, ...
