Abstract

The invention discloses a high strength abrasion resistant flame retardant polycarbonate material and a preparation method thereof. The high strength abrasion resistant flame retardant polycarbonate material comprises the following components by weight: 65%-80% of polycarbonate resin, 5%-10% of a flame retardant, 5%-15% of nanometer silicon dioxide, 0.5%-3% if an organosilicon wear resistant agent, 1%-3% of a compatilizer, 0.1%-0.5% of an antioxidant and 0.1%-1.5% of a lubricant. The invention has the beneficial effect that compared with the prior art, the polycarbonate material prepared by the invention has excellent comprehensive mechanical properties and processing properties; the added organosilicon wear resistant agent can reduce friction coefficient and wear volume and improve the wear resistance of materials; the added flame retardant realizes flame retardance of grade UL94V-0 and the effects of no halogen, environment-friendliness, safety and high efficiency; and the added silica can improve strength and improve the temperature resistance, wear resistance and scratch resistance of the material.
