Problems solved by technology

However, the physical properties of the former flame-retardant ABS are poor, and the extrusion process is usually difficult, which is not conducive to industrial production, while the latter requires a high molding processing temperature, which is easy to cause damage to the rubber phase graft shell in the ABS, affecting the growth rate. Tough efficiency, and does not meet the environmental protection trend of energy saving

Abstract

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.
