Patent ID: 8058333

Claim:
A flame retarding composite material, consisting of: component (A): a first resin which is polycarbonate (PC) resin; component (B): a second resin which is acrylonitrile butadiene styrene (ABS) resin; component (C): a phosphorus-containing flame retardant being derivatives having the following formula 3: wherein n2 is any numeral of 1 to 10; wherein the derivative having formula 3 is diphenyl phosphonimidate; and component (D): an additive, including glass fibers, wherein the amount of polycarbonate resin based on the composite material is 60 wt % to 80 wt %, the amount of acrylonitrile butadiene styrene resin based on the composite material is 15 wt % to 35 wt %, the amount of the phosphorus-containing flame retardant is 10 wt % to 20 wt %, and the amount of glass fibers based on the composite material is 5 wt % to 37 wt %; all the components are subject to distributive mixing to form the target composite material.
