Preparation method of flame-retardant polycarbonate material

Abstract

The invention discloses a preparation method of a flame-retardant polycarbonate material. Ammonium polyphosphate and antimonous oxide are mixed and dispersed into oligomer, so that the dispersibility of an inorganic flame-retardant aid in polymers is effectively improved, the stability of finished products is improved and the flame-retardant and waterproof properties of the finished products are improved.

Description

technical field

[0001] The invention belongs to the field of materials, and in particular relates to a preparation method of an oligomer flame-retardant polycarbonate material. Background technique

[0002] Polycarbonate 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;

[0003] Its current development momentum is very rapid, and it is rapidly extending and integrating into computer manufacturing, aerospace, blue light and other industrial industrializ...
