Polymer metal wear-resistant self-lubricating composite material, production method thereof, and guide bearing

Abstract

The invention relates to a polymer metal wear-resistant self-lubricating composite material, a production method thereof, and a manufactured guide bearing. The product comprises a metal layer and a polymer layer. The polymer layer comprises, by weight: 50-80 parts of a polymer, 10-30 parts of potassium hexatitanate whisker treated by using a coupling agent, 10-20 parts of a solid lubricant, and processing auxiliary agents. A bonding surface between the metal layer and the polymer layer has at least one straight groove on a first direction, and at least one transverse groove, inclined groove or spiral-shaped groove on a direction crossing the first direction. The production method comprises the steps that: the 50-80 parts by weight of the polymer, 10-30 parts by weight of potassium hexatitanate whisker treated by using the coupling agent, 10-20 parts by weight of solid lubricant, and processing auxiliary agents are uniformly mixed; the mixture is base-dried, extruded, and cut into particles; the particles are bake-dried; the metal layer is processed into metal parts satisfying size and structural requirements; the metal parts are preheated; the metal parts are loaded into a mold; and injection molding processing or mold pressing processing is carried out.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a polymer / metal wear-resistant self-lubricating composite material. The invention also relates to a production method of a polymer / metal wear-resistant self-lubricating composite material. The invention also relates to a Guide bearings made of polymer / metal wear-resistant and self-lubricating composite materials. Background technique [0002] Polymer wear-resistant and self-lubricating materials have great potential for application in structural parts such as machinery and automobiles due to their advantages of wear resistance, corrosion resistance, self-lubrication, and less damage to mating parts. However, as mechanical structural parts, they also have insufficient strength and rigidity, and thermal conductivity Problems such as poor heat dissipation, structural parts made of wear-resistant and self-lubricating polymer materials are wear-resistant, corrosion-r...

Problems solved by technology

Because polymers and metals have different molecular structures, their physical properties and thermal properties are also different, such as the thermal expansion and contraction characteristics of the two are very different, so it is difficult to ensure the firmness of the two with the traditional embedded composite material structure to combine
