Embodiment 1

[0052] (1) 20kg of weather-resistant and environmentally friendly low-bromine flame retardant FR-245, 60kg of water, and 3kg of dispersant were added to the reactor, and emulsified and dispersed at high shear for 90min to obtain a flame retardant suspension. Next, adjust the pH value of the flame retardant suspension and 1 kg of melamine-formaldehyde prepolymer to 5 with 5% dilute hydrochloric acid, and then heat the mixed solution to 70° C. for 3 hours. The reacted product was washed with water, filtered, and vacuum-dried to obtain about 21 kg of microencapsulated environmental protection flame retardant.

[0053] (2) After mixing 70kg ABS and 0.4kg coupling agent KH550, stir on a high-speed mixer for 2min, then add 0.3kg antioxidant 168, 0.3kg antioxidant 1076, 0.5kg light stabilizer 327, 0.5kg light stabilizer in turn 770, 1kg of calcium stearate, and 2kg of titanium dioxide were mixed evenly, and finally 20kg of microencapsulated environmental protection flame retardant an...

[0056](1) 20kg of weather-resistant and environmentally friendly low-bromine flame retardant FR-245, 60kg of water, and 3kg of dispersant were added to the reactor, and emulsified and dispersed at high shear for 90min to obtain a flame retardant suspension. Next, adjust the pH value of the flame retardant suspension and 1 kg of melamine-formaldehyde prepolymer to 5 with 5% dilute hydrochloric acid, and then heat the mixed solution to 70° C. for 3 hours. The reacted product was washed with water, filtered, and vacuum-dried to obtain about 21 kg of microencapsulated environmental protection flame retardant.

[0057] (2) After mixing 75kg ABS and 0.4kg coupling agent KH550, stir on a high-speed mixer for 2min, then add 0.2kg antioxidant 168, 0.2kg antioxidant 1076, 0.3kg light stabilizer 327, 0.3kg light stabilizer in turn 770, 1kg of calcium stearate, and 1kg of titanium dioxide were mixed uniformly, and finally 18kg of microencapsulated environmental protection flame retardant ...

Embodiment 3

[0060] (1) 20kg of weather-resistant and environmentally friendly low-bromine flame retardant FR-245, 60kg of water, and 4kg of dispersant were added to the reactor, and emulsified and dispersed at high shear for 70min to obtain a flame retardant suspension. Next, adjust the pH of the flame retardant suspension and 1.5 kg of melamine-formaldehyde prepolymer to 6 with 5% dilute hydrochloric acid, and then heat the mixed solution to 80° C. and hold for 2.5 hours. The reacted product was washed with water, filtered, and vacuum-dried to obtain about 21.5 kg of microencapsulated environmental protection flame retardant.

[0061] (2) After mixing 72kg ABS and 0.4kg coupling agent KH550, stir on a high-speed mixer for 2min, then add 0.3kg antioxidant 168, 0.3kg antioxidant 1076, 0.5kg light stabilizer 327, 0.5kg light stabilizer in turn 770, 1kg of calcium stearate, and 1kg of titanium dioxide were mixed uniformly, and finally 20kg of microencapsulated environmental protection flame ...

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

technical field [0001] The invention relates to a composition of acrylonitrile-butadiene-styrene copolymer (hereinafter referred to as ABS) and a preparation method thereof. Background technique [0002] 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 properties. . However, the oxygen index of ABS is only 18.3% to 20.0%, which is a flammable material, and ABS has no self-extinguishing property. When burning, the flame turns yellow and produces black smoke. The smoke density is as high as 720. One of the big varieties. [0003] Brominated flame retardants have high efficiency, moderate price and many varieties. At present, 70% to 80% of the electrical and electronic products for export in my country use such flame retardants. In order to improve...
