Problems solved by technology

However, the addition of carbon fiber will produce a "candle wick effect", and the flame retardancy of the material is not good
The development of my country's carbon fiber reinforced PC alloy technology is in its infancy, far behind developed countries, and there are bottlenecks in many aspects. The existing carbon fiber reinforced PC / ABS alloy cannot meet the needs of industrial and military fields

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular, the invention relates to a high-modulus, high-flow, halogen-free flame-retardant PC / ABS alloy material and a preparation method thereof. Background technique [0002] PC / ABS alloy is a thermoplastic engineering plastic alloy with excellent performance, easy processing, high quality and low price, and great commercial value. It is widely used in the fields of automobile industry, household appliances and office equipment. In order to meet the fire safety requirements in the application field, the PC / ABS alloy must have good flame retardancy, and the flame-retardant PC / ABS alloy material is based on this to improve the flame retardancy of the material and have good fire resistance. Studies on PC / ABS alloys have shown that bromine-containing flame retardants have the best flame retardant effect on materials, and their flame retardant mechanism is to inhibit the gas phase pro...
