Abstract

The invention discloses a fire retardant enhanced high-temperature-resistant polycarbonate composite material and a preparation method thereof. The fire retardant enhanced high-temperature-resistant polycarbonate composite material is prepared from the following ingredients in parts by weight: 40 to 70 parts of polycarbonate, 30 to 50 parts of carbon fiber, 5 to 13 parts of heat-resistant agents,4 to 14 parts of main fire retardants, 2 to 10 parts of auxiliary fire retardants, 0.4 to 1.6 parts of coupling agents, 0.2 to 0.8 part of antioxidants, 0.3 to 1.2 parts of lubricating agents and 0.5to 2.2 parts of toughening agents. The carbon fiber is added into the polycarbonate, so that the fire retardant performance, heat resistant performance, wear resistance and intensity of the compositematerial can be greatly improved; meanwhile, the added heat-resistant agents further improve the high-temperature resistant capability of the composite material; all ingredients are reasonably compounded. The prepared composite material has super high toughness and good processing flowability; high rigidity performance is excellent; the low tilting performance is excellent; the safety and the environment-friendly effects are realized.

Description
