Problems solved by technology

However, because of the burning characteristics of carbon black itself and the wick effect of carbon fiber (like the wick burning when a candle burns), it is difficult to make the flame retardancy of conductive materials, and the colors of carbon black and carbon fiber are all black, which cannot be formulated Other colors cannot meet the current market's color demand for halogen-free flame-retardant conductive materials
[0006] In view of this, it is necessary to develop a halogen-free flame-retardant PC conductive material to solve the problem that PC conductive materials in the prior art cannot be flame-retardant and colorful.

Abstract

The invention relates to the technical field of high polymer materials, and specifically relates to a halogen-free flame-retardant polycarbonate (PC) conductive material and a product thereof. The halogen-free flame-retardant PC conductive material comprises the following components in parts by weight: 80-99.5 parts of PC resin, 0.02-0.04 part of single-walled carbon nanotubes and 0.2-2 parts of aflame retardant. The product is produced after the halogen-free flame-retardant PC conductive material is shaped. According to the halogen-free flame-retardant PC conductive material disclosed by theinvention, the single-walled carbon nanotubes are added as a conducting medium, and the flame retardant is added to enhance flame retardancy, so that the high-performance halogen-free flame-retardantPC conductive material can be prepared. In addition, the material can be regulated to be colorized, and requirements of the current market for colorful conductive materials are met.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of polymer materials, in particular to a halogen-free flame-retardant PC conductive material and its products. [0003] 【Background technique】 [0004] With the multi-functionalization of plastic products and the high integration of electronic circuits, materials with conductive properties are being used more and more widely. PC materials (polycarbonate, Polycarbonate) have high impact resistance and their own flame retardancy can reach V -2. Good weather resistance, widely used in electronic and electrical products. [0005] The surface resistance of pure PC materials is above 10^14 (10 to the 14th power) ohms. Traditionally, PC conductive materials are obtained by adding carbon black or carbon fibers. However, because of the burning characteristics of carbon black itself and the wick effect of carbon fiber (like the wick burning when a candle burns), it is difficult to make the flame retardancy of...
