Abstract

The invention relates to the technical field of high polymer materials, and particularly discloses a high-performance halogen-free flame-retardant PC / CNT conductive material and a product thereof. According to the high-performance halogen-free flame-retardant PC / CNT conductive material. 100 parts by mass of a conductive material finished product comprises the following components in parts by mass: 20-90 parts of polycarbonate; 3 to 7 parts of carbon nanotubes; and 6.5 to 14 parts of a flame retardant. According to the high-performance halogen-free flame-retardant PC / CNT conductive material and the product thereof disclosed by the invention, the carbon nano tube is used as a conductive medium, so that the conductive material has relatively good antistatic performance, the flame-retardant grade reaches 1.0 mm V-0, more than 50% of relatively good physical characteristics of the conductive material are retained, and the obtained product has relatively good antistatic performance, flame retardance and impact resistance.

Description

【Technical field】 [0001] The invention relates to the technical field of polymer materials, in particular to a high-performance halogen-free flame-retardant PC / CNT conductive material and its products. 【Background technique】 [0002] Polycarbonate (PC) is a polymer with carbonate groups in its molecular chain. According to the structure of ester groups, 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. [0003] As a one-dimensional nanomaterial, carbon nanotubes (CNTs) are light in weight, perfectly connected in a hexagonal structure, and possess many unusual mechanical, electrical, and chemical properties. In recent years, with the in-depth research of carbon nanotubes and nanomaterials, their broad application prospects are constantly showing. [0004] In PC-based carbon nanotube conductive materials, ...
