Flame-retardant anti-aging ABS and preparation thereof

Abstract

The invention relates to a composition of an arcylonitrile-butadiene-styrene and a preparation method thereof in particular to a fire-retardant antiaging ABS. The fire-retardant antiaging ABS comprises the following components in mass percentage: 60 to 80 percent of ABS, 12 to 25 percent of microencapsulation environment-friendly fire retardant, 0 to 0.5 percent of antioxidant 1076, 0 to 0.5 percent of antioxidant 168, 0.1 to 1.0 percent of light stabilizer 770, 0.1 to 1.0 percent of light stabilizer 327, 0.1 to 1.0 percent of coupling agent KH550, 4 to 10 percent of diantimony trioxide, 1.0 to 3.0 percent of calcium stearate and 1.0 to 3.0 percent of titanium pigment. The heat-resistant environment-friendly fire-retardant antiaging ABS mainly resolves the conflict between the fire retardant and the light stabilizer.

Description

Flame-retardant anti-aging ABS and preparation method thereof technical field The invention relates to a composition of acrylonitrile-butadiene-styrene copolymer (hereinafter referred to as ABS) and a preparation method thereof. Background technique As one of the five general-purpose plastics, ABS is widely used in household appliances, electronics, auto parts, office and sporting goods due to its excellent processing, electrical insulation and other comprehensive physical properties, high gloss and excellent electroplating performance. . However, the oxygen index of ABS is only 18.3% to 20.0%. It is a flammable material, and ABS has no self-extinguishing property. When burning, the flame is yellow and black smoke is produced. The smoke density is as high as 720. One of the largest breeds. Brominated flame retardants have high efficiency, moderate price, and many varieties. At present, 70% to 80% of my country's electrical and electronic products for export use such fla...

Problems solved by technology

The same is true of the fact that ordinary flame-retardant ABS will completely turn yellow after 1 day of exposure, which greatly limits the use of flame-retardant ABS outdoors.
