The invention relates to a high-performance
halogen-free
flame retardant ABS modified resin and a preparation method thereof. The resin comprises the following components with the content (in parts by weight): 100 ABS resin, 4-30
polyamide, 5-25
phosphate fire retardant, 0.1-0.5 anti-drippage agent, 5-10
toughening agent, 1-5 nano filler, 1-5 compatilizer, 0.2-1
antioxidant, 0.1-0.5 light stabilizer and 1-5
processing agent. Compared with the prior art, the invention has reasonable technique, and overcomes the defects of poor
flame retardant property and low
impact strength of the existing
halogen-free
flame retardant ABS; and the invention adopts a novel high-efficiency
halogen-free flame retardant compounding synergism technology, a novel
polyamide coal-forming agent, the high-efficiency synergism between organic and inorganic fire retardants, and the master
batch method processing technique, thus endowing the resin with high
fire resistance on the basis of improving the original good performances (especially the
impact performance) of the ABS resin, and having wide application prospect.
