Abstract

The invention relates to the technical field of material preparation, and discloses a spherical resin-based brush composite material and a preparation method thereof. The spherical resin-based brush composite material of the present invention comprises the following components in mass percentage: microcrystalline graphite powder 15-30%, graphite powder 43-63%, chelating agent 0.5-3%, binder 20-27%, compound lubrication Agent 1.5‑4%, release agent 0.02‑0.08%. The present invention spheroidizes the graphite resin powder and eliminates the edges and corners of the powder, thereby improving the self-fluidity of the powder and achieving isotropic characteristics. Get the greatest degree of matching with the working characteristics of the motor.

Description

technical field [0001] The invention relates to the field of material preparation, in particular to a spherical resin-based brush composite material and a preparation method thereof. Background technique [0002] As we all know, the powder mixture can be composed of the main filler of the composite material and the additives therein. The main filler in the brush material acts as a functional main phase and has typical functions such as conductivity, reinforcement and lubrication. The additives in it can play the role of "icing on the cake" according to the different working conditions of the brush products. In a sense, the brush powder mixture plays a decisive role in the production of the brush. How to select and further process the powder mixture to obtain a composite material with controllable micro-interface and designable performance is the current electric carbon industry, and even provides experimental basis and technical support for the research and development of c...
