Laminate Bearing And Methods Of Manufacturing The Same

摘要

A maintenance-free and self-lubricant slide bearing comprising a metal support, an intermediate adhesive layer applied directly thereto and a sliding layer based on UHMWPE. The bearing laminate is characterized by a high peel-strength and does not require a surface pre-treatment of the metal support to achieve a strong bonding of the UHMWPE sliding layer to the metal support. The preferred adhesive in the intermediate layer is an anhydride-grafted polyethylene. The invention further includes a process of making the bearing laminate.

1. A bearing article formed from a laminate, the laminate comprising:
a metal support; an intermediate adhesive layer in direct contact with the metal support, the adhesive layer comprising a grafted polyolefin according to formula (I) wherein R1 includes an alkyl or cycloalkyl group comprising an acid anhydridegroup or at least two polar functional groups, and R2 is H, C1-C5 Alkyl or phenyl; and an ultrahigh molecular weight polyethylene (UHMWPE) layer in direct contact with the intermediate layer.
