Abstract

The invention discloses a flame-retardant glass fiber-reinforced ABS material with a high CTI value and a high GWIT value. The ABS material comprises the following components: by weight, 45 to 68% of ABS, 6 to 20% of a compound fire retardant, 3 to 15% of antimonony oxide, 20 to 30% of a glass fiber, 2 to 10% of a compatilizer, 0.1 to 1% of an anti-oxidant and 0.1 to 1% of a metallic oxide. In preparation of the ABS material, all the components are added into a high-speed mixer for mixing for 2 to 5 min, and then discharging and extrusion granulation in a twin-screw extruder are carried out, wherein processing temperature of the twin-screw extruder is 200 to 230 DEG C and screw revolution is 30 to 40 Hz. Compared with the prior art, the ABS material prepared in the invention has the advantages of high glow wire temperature, a high tracking index, environment-friendliness, balanced comprehensive properties and the like through utilization of a novel flame-retardant compounded system in the invention.

Description

technical field [0001] The invention relates to an ABS material, in particular to a flame-retardant glass fiber-reinforced ABS material with high CTI value and high GWIT value. Background technique [0002] ABS resin features: The resin has good comprehensive performance. High impact strength, chemical stability, good electrical properties; good fusion with plexiglass, made of two-color plastic parts, and the surface can be chrome-plated and spray-painted; it has high impact resistance, high heat resistance, flame retardancy, reinforcement, and transparency The same level; fluidity is a little worse than HIPS, better than PMMA, PC, etc., and good flexibility. In the 21st century, electronic and electrical communication appliances, home appliances, and electrical equipment are developing towards high-performance miniaturization, and the requirements for flame-retardant ABS materials are getting higher and higher. , along with the mankind's understanding to environmental prot...
