Abstract

The invention discloses a graphene modified polycarbonate composite material and a preparation process thereof. The graphene modified polycarbonate composite material is mainly prepared from, by weight, 100 parts of polycarbonate, 10-12 parts of polystyrene, 10-12 parts of graphene, 10-12 parts of calcium sulfate whiskers, 0.1-0.4 part of antioxidant 1010, 1-4 parts of polytetrafluoroethylene and1-3 parts of titanate coupling agent. The invention further discloses a preparation process of the graphene modified polycarbonate composite material. According to the preparation method, the grapheneis firstly adopted to modify the calcium sulfate whiskers, so that the length-diameter ratio of the calcium sulfate whiskers is further improved, the diameter of the calcium sulfate whiskers is reduced, and the compatibility and the interface bonding force of the calcium sulfate whiskers and a matrix can be further improved. The graphene modified polycarbonate composite material disclosed by theinvention is good in fatigue resistance, low in notch sensitivity and particularly suitable for manufacturing shell materials and the like.

Description

technical field [0001] The invention relates to a polycarbonate composite material and a preparation process thereof, in particular to a graphene-modified polycarbonate composite material and a preparation process thereof. Background technique [0002] Polycarbonate (PC), is a typical hard and brittle polymer with good comprehensive performance, tensile strength, compressive strength, bending strength and other properties are equivalent to polyamide 6 or polyamide 66, and the impact strength is also high For all aliphatic polyamides and most engineering plastics. However, the poor fatigue resistance and high notch sensitivity of polycarbonate limit the application of PC. Contents of the invention [0003] The invention provides a graphene-modified polycarbonate composite material and a preparation process thereof to solve the technical problems of good fatigue resistance and low notch sensitivity of existing polycarbonate materials. [0004] The technical scheme that the...
