Abstract
The invention relates to a glass fiber reinforced flame-retardant ABS composite material having a high impact resistance and a high heat resistance, and its preparation technology. The composite material is prepared through adding proper amounts of a compatilizer, a dispersant, a coupling agent and an antioxidant to main raw materials comprising 20-85 parts of ABS, 10-30 parts of GF (glass fiber), 0-15 parts of a flexibilizer and 5-35 parts of a flame retardant. The above raw materials are weight according proportions, and undergo blending extrusion on a double screw extruder. The flexibilizer introduced to the glass fiber reinforced flame-retardant ABS composite material having a high impact resistance and a high heat resistance is novel, has a good compatibility with the ABS, and can promote the dispersion of the flame retardant, improve the interface combination of the flame retardant and the resin, greatly improve the impact strength of the plastic, reduce the application amount of the flame retardant, reduce the cost, and improve the market competitiveness. The flame retardant introduced in the invention is novel, has the advantages of high heat stability, ideal ultraviolet resistance, ideal migration resistance, and ideal notch impact strength, and is suitable for glass fiber reinforced systems.
Description
technical field [0001] The invention discloses a high-impact, high-heat-resistant glass fiber-reinforced flame-retardant ABS composite material and a preparation process thereof. It specifically relates to a high-impact, high-heat-resistant, high-flame-retardant ABS composite material used in industries with high fire protection requirements, such as automobiles, home appliances, and construction. technical background [0002] ABS resin is a kind of engineering plastic with good comprehensive performance, which has the characteristics of excellent cold resistance, oil resistance, electrical performance, dimensional stability and processing fluidity. Widely used in auto parts, household appliances, construction, instrumentation, office equipment, daily appliances and other fields, it is currently the most widely used variety of general engineering plastics. With the improvement of the overall safety awareness of the society, most products are required to be flame retardant a...
