Abstract

The invention discloses a conductive reinforced PC / ABS alloy. The conductive reinforced PC / ABS alloy comprises following ingredients, by mass, 40 to 60% of PC, 20 to 30% of ABS, 5 to 10% of alkali-free glass fiber, 8 to 15% of a conductive filling material, 2 to 8% of phosphorus-nitrogen flame retardant, 0.5 to 2% of a light stabilizer, 1 to 3% of a flexibilizer, 0.1 to 0.5% of an antioxidant, and 0.5 to 1% of a lubricant. The conductive filling material is one selected from polyacrylonitrile-based carbon fiber, vapor grown carbon nano-fibers, and conductive carbon black. Beneficial effects of the conductive reinforced PC / ABS alloy are that: the conductive reinforced PC / ABS alloy possesses advantages of PC and ABS, and excellent mechanical properties, flame resistance, aging resistance, conductivity, and glossiness; and is low in cost; a preparation method is simple; and industrialized production can be easily realized.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a conductive enhanced grade PC / ABS alloy. Background technique [0002] PC / ABS alloy (polycarbonate / acrylonitrile-butadiene-styrene copolymer), which combines the excellent properties of PC and ABS, can reduce the cost and melt viscosity of PC on the one hand, improve fluidity, and improve Its processing performance, on the other hand, can improve the stress cracking resistance of PC and reduce the sensitivity of impact to thickness and notch. It is a polymer alloy with relatively ideal performance. It has good formability and low temperature impact resistance. heat distortion temperature and light stability. Judging from the solubility parameters of PC and ABS, the two are relatively close, but the compatibility of PC and ABS is limited when the two polymers are blended. Adding the third component to the PC / ABS alloy can significantly improve the compatibility and me...
