Abstract

The invention relates to a special anti-flaming conductive polycarbonate material and a preparation method thereof, and belongs to the technical field of anti-flaming conductive plastics. The formula of the special anti-flaming conductive polycarbonate material comprises the following components in parts by weight: 61 to 85 parts of polycarbonate, 5 to 15 parts of flame retardant, 6 to 20 parts of conductive auxiliary, 1 to 15 parts of flexibilizer, 0.1 to 0.5 part of dispersing auxiliary, 0.1 to 0.5 part of coupling agent and 0.1 to 0.5 part of heat stabilizer. The preparation method comprises the following steps: (1) preparing mixture in a mixing machine; (2) adding the mixture into an extruder to melt and plasticize the mixture by heating; (3) extruding, cooling and granulating to obtain the special material. The special anti-flaming conductive polycarbonate material prepared by the method has relatively good flame resistance, electrical conductivity and mechanical property, and can meet the requirement of the packing material of an electronic component.

Description

technical field [0001] The invention belongs to the technical field of flame-retardant conductive plastics, and in particular relates to a special material for flame-retardant conductive polycarbonate and a preparation method thereof. Background technique [0002] Various electronic components such as chips, transistors, capacitors, etc. will be damaged due to static electricity during production and transportation, causing huge losses to electronic component manufacturers and users, so their packaging materials must have conductive or antistatic properties. In order to discharge harmful static charges. After additives such as conductive additives or antistatic agents are added to the packaging materials of electronic components, certain conductive or antistatic effects can be achieved. However, as the electronics industry has higher and higher requirements for packaging materials, existing packaging materials still have shortcomings such as poor flame retardancy and po...
