Problems solved by technology

Due to the different densities of copper powder and graphene powder, the current mixer is used to mix copper powder and graphene powder, resulting in uneven mixing of copper powder and graphene powder. Copper powder and graphene powder are easy to fall off, the product quality is poor, and the content of graphene is low, which does not achieve a good lubrication effect, high friction coefficient, and short service life

Abstract

The invention belongs to the technical field of composite sintered wear-resistant plates and preparation methods, and discloses a composite sintered wear-resistant plate, a preparation method and a special stirring and mixing device. Its main technical features are: including a substrate, a rough surface is provided on one side of the substrate, a copper powder layer is provided outside the rough surface, and a graphene-copper powder mixed layer is provided on the outer surface of the copper powder layer. The graphene powder and copper powder weight ratio are 1-2:100, and the particle size of the graphene powder and copper powder is 200-300 mesh, so that the graphene copper powder mixed layer is more firmly combined with the substrate, and the graphene The content of carbon dioxide is high, the lubricating effect is good, and the friction coefficient of the bearings and other products made is low, which greatly prolongs the service life. Inject high-pressure gas and turn on the stirring mechanism, so that the mixing is more uniform, which can effectively increase the content of graphene powder and improve the wear resistance of the composite sintered wear-resistant plate.

Description

Technical field [0001] The invention belongs to the technical field of composite sintered wear-resistant plates, processing equipment and preparation methods, and in particular relates to a composite sintered wear-resistant plate, a preparation method and a special mixing device. Background technique [0002] In the field of motor vehicle bearings, in order to improve the wear resistance, sintered wear plates are used to sinter a layer of wear-resistant copper powder or other powder on the steel plate. The strength and impact resistance of the steel plate are relatively strong. The copper powder or other powders are wear-resistant The performance is good, so its comprehensive performance is greatly improved. In order to improve the wear resistance, graphene powder is added to the copper powder. Due to the different densities of copper powder and graphene powder, the mixing of copper powder and graphene powder by the current mixer results in uneven mixing of copper powder and gra...
