Abstract

The invention discloses a high-impact low-volume-resistance ABS (Acrylonitrile Butadiene Styrene) flame-retardant composite material which is prepared from the following raw materials: ABS resin, a styrene-butadiene copolymer, a flame retardant, an antistatic agent, a structural strength enhancer and an adaptive modifier, the raw materials comprise, by mass, 100 parts of ABS resin, 20-30 parts of a styrene-butadiene copolymer, 3-10 parts of a flame retardant, 1-4 parts of an antistatic agent, 0.5-2 parts of a structural strength reinforcing agent, and 1-5 parts of an adaptive modifier. According to the ABS flame-retardant composite material with high impact resistance and low volume resistance, the styrene-butadiene copolymer is added, so that the antistatic performance of the antistatic agent in the composite material is improved, and meanwhile, the toughness of a composite material system is improved; by adding the structural strength reinforcing agent, the impact resistance, tensile resistance and other mechanical properties of the composite material are improved; the antistatic agent and the flame retardant do not interfere with each other, and the obtained ABS flame-retardant composite material has excellent impact strength, good / stable antistatic performance and excellent flame retardant performance.

Description

technical field [0001] The invention relates to the technical field of composite materials and preparation thereof, in particular to an ABS flame-retardant composite material with high impact resistance and low volume resistance and a preparation method thereof. Background technique [0002] Acrylonitrile-butadiene-styrene copolymer (ABS) is a terpolymer of acrylonitrile, 1,3-butadiene and styrene. It is a thermoplastic with high strength, good toughness and easy processing. The surface of the processed product is smooth, easy to dye and electroplating, and the product can be used normally in a wide temperature range of -25℃~60℃. At the same time, ABS can be mixed with various resins to form a blend. In the technology, ABS is mainly used for alloys, plastics, and ABS grades. [0003] Although ABS resin has good mechanical properties and performance, it can be widely used in various fields, but the high insulating electrical properties of ABS resin itself (surface resistivit...

AI Technical Summary

Problems solved by technology

[0003] Although ABS resin has good mechanical properties and performance, it can be widely used in various fields, but the high electrical insulation properties of ABS resin itself (surface resistivity is 4×10 15 Ω) and low oxygen index (20%) make it easy to accumulate static electricity and flammable, especially prone to combustion caused by static electricity accumulation, which greatly limits the application of ABS materials in mines, petrochemicals and other fields

In order to increase the antistatic and flame retardant properties of ABS materials, the existing technology usually processes ABS resin into antistatic ABS flame retardant composite materials by adding antistatic agents and flame retardants, but the antistatic agents and flame retardants Addition will inevitably lead to a decline in the mechanical properties of the composite material such as impact strength, and it is easy to cause mutual interference between the antistatic agent and the flame retardant, and it is difficult to maintain the long-lasting and stable antistatic performance
