Problems solved by technology

[0004] Although halogen-free flame retardant ABS has been a research hotspot in the world for many years, due to the low efficiency of halogen-free flame retardants, large additions, and poor compatibility with resins, the mechanical properties of materials are severely reduced, and it has always been a halogen-free flame retardant. Major barriers to widespread market adoption

Description

technical field [0001] The invention relates to the technical field of preparation of flame-retardant polymer materials, in particular to a modified halogen-free flame-retardant ABS composition and a preparation method thereof. Background technique [0002] ABS plastic has been widely used in the electrical, electronic and automotive industries due to its excellent chemical resistance, mechanical properties and processing properties. However, due to the flammability of ABS, its further and wider application is limited. [0003] In the last ten years, halogenated flame retardants have been successfully used to prepare flame-retardant ABS plastics, but halogenated flame-retardant materials themselves will release toxic hydrogen halide gas during combustion, which is no less harmful than Fire itself is a threat to humans. Therefore, the EU RoHS environmental protection directive issued in 2003 listed a variety of halogenated flame retardants on the list of restricted hazardou...
