Abstract

The invention discloses a high-heat-conducting and insulating AS (Acrylonitrile-styrene) material for a motor fan blade and a preparation method of the high-heat-conducting and insulating AS material. A formula of the high-heat-conducting and insulating AS material for the motor fan blade is prepared from the following components: 40 to 70 parts of AS resin, 30 to 60 parts of a heat-conducting material, 10 to 20 parts of an insulating material, 5 to 15 parts of a toughening agent, 0.5 to 3 part of a coupling agent, 2 to 5 parts of a compatilizer, 0.5 to 1 parts of a lubricant and 0.5 to 2 parts of an antioxidant. The preparation method comprises the following steps: weighing the heat-conducting material and the insulating material in the formula according to weight ratios, and adding into a high-speed mixer in sequence; after carrying out surface treatment, adding the other components in sequence; sufficiently stirring and mixing through the high-speed mixer; melting, extruding and granulating through a double-screw extruder; after drying, carrying out injection molding and carrying out a performance test. A product prepared by the formula disclosed by the invention has the advantages of good heat-conducting property, excellent insulating property and great bending modulus; the formula disclosed by the invention can be used for preparing various types of materials of the fan blades of motors and electric appliances, and traditional polypropylene and nylon materials are replaced.

Description

technical field [0001] The invention relates to the field of motor and electric fan blade materials, in particular to a high thermal conductivity insulating AS material for motor fan blades and a preparation method thereof. Background technique [0002] The motor blade is the most representative and important part of the motor, and the performance of the motor is closely related to its stable operation.
