Abstract

The invention discloses a halogen-free flame-retardant high-toughness ABS resin modified by a nanoscale flame retardant and a preparation method of the ABS resin. The ABS resin is prepared from the following raw materials in percentage by weight: 45-85% of ABS resin, 10-50% of a composite flame retardant; 1-3% of a lubricant; 0.01 to 2% of dispersing agent; and 0.01 to 0.5% of an antioxidant; the halogen-free flame-retardant high-toughness ABS resin mainly solves the problems that the halogen-free flame retardant has poor compatibility with ABS and the product performance is reduced when a large amount of halogen-free flame retardant is added. The preparation method is characterized in that SAN grafted PBL latex microsphere coated nanoscale phosphaphenanthrene grafted modified aluminum hydroxide or magnesium hydroxide is used as a flame retardant, so that the flame-retardant synergistic effect of metal hydroxide and a phosphorus flame retardant is exerted, the halogen-free flame retardant is greatly promoted to be well dispersed in ABS resin, and the toughening effect is achieved. Results show that when the effective addition amount of the flame retardant compound is as low as 5%, the flame retardant ABS can still reach the UL 94 V-0 level, and the notch impact strength is larger than 13 KJ / m < 2 >.

Description

technical field [0001] The invention relates to the technical field of polymer material processing, in particular to a halogen-free flame-retardant high-toughness ABS resin composition containing a nano-scale flame retardant and a preparation method thereof. Background technique [0002] ABS material is widely used in household appliances, children's toys, mechanical parts, automotive interior and exterior decoration and other fields because of its high strength, good toughness, easy processing and good gloss. However, ABS is extremely flammable, and its horizontal burning speed is about 2.5-5.1cm / min, and it produces a large amount of black smoke and toxic gas when burning, which is very easy to cause a great safety hazard. The traditional flame retardant method is to add a halogen flame retardant. Although the resulting product has a good flame retardant effect, it will produce toxic and corrosive gases when burned, which has great side effects on people and the environmen...
