Abstract

The invention discloses an antistatic antibacterial PC (polycarbonate) / ABS (acrylonitrile-butadiene-styrene copolymer) composite material comprising the following components by weight: 63-93 parts of polycarbonate, 57-65 parts of ABS, 33-47 parts of a flame retardant agent, 29-44 parts of a nano antibacterial agent, 41-47 parts of an antiaging agent, 24-32 parts of an antistatic agent, 24-32 parts of a compatibility agent, 22-26 parts of a lubricant, 19-23 parts of a toughening agent, 15-20 parts of a synergistic agent, 10-16 parts of an insulation agent, 10-16 parts of a yellowing resistant agent and 17-24 parts of a wear-resisting agent. The antistatic antibacterial PC / ABS composite material has excellent antistatic performance, avoids the deleterious effects of electrostatic, and also has antibacterial properties, more than 99% bacteriostasis rate can be maintained for a long term, the composite material has good anti-aging properties, is flame retardant, simultaneously reduces the combustion smoke density, has excellent characteristics of wear resistance, yellowing resistance, high voltage resistance and electric arc resistance, and is suitable for different use requirements.

Description

technical field [0001] The invention relates to an antistatic and antibacterial PC / ABS composite material, which belongs to the technical field of PC / ABS composite materials. Background technique [0002] Polycarbonate (PC) is a polymer in which the repeating structural unit of the molecular chain is a carbonate type, and it is an engineering plastic with excellent comprehensive properties. PC has the advantages of high impact strength, good creep resistance and dimensional stability, heat resistance, transparency, low water absorption, non-toxic, and excellent dielectric properties. At the same time, PC has the disadvantages of poor processing fluidity, easy stress cracking, sensitivity to notches, easy wear, poor chemical resistance, and high price. (Acrylonitrile / Butadiene / Styrene) Copolymer (ABS) is a thermoplastic resin with good chemical corrosion resistance, good processability, high cost performance, and the disadvantage is poor heat resistance and weather resistanc...
