Abstract
A modified PC/ABS alloy mainly comprises the components in mass fraction: 55 to 70 for PC/ABS, 15 to 25 for stiffening agent, 3 to 8 for compatilizer, 4 to 8 for bromide fire retardant, 1 to 3 for stibium fire retardant, 3 to 8 for acrylic acid impact resistance modifier, and 0.2 to 0.5 for oxidation inhibitor. By adding harden stiffening agent, compatible plasticizer and fire retardant in the mixing process, the modified PC/ABS of the invention improves the surface hardness of the PC/ABS alloy as well as to further achieve the surface hardness and fire resistance and meets the technological requirement with little changing of the mechanical properties of PC/ABS, thus widening the application of PC/ABS alloy.
