Sliding bearing material of elastoplastic polymer alloy

Abstract

The invention discloses a sliding bearing material of elastoplastic polymer alloy, comprising the raw materials of the following mass portions: 100-120 portions of prepolymer resin, 20-45 portions of crosslinking curing agent, 1-6 portions of antiwear agent, 2-17 portions of lubricating agent, 0.1-1 portion of defoamer and 0-0.5 portion of pressure additive. The material has the characteristics of wear resistance, impact resistance and high limit PV value, and suitably used as a nonmetallic bearing material for water or self lubricating.

Description

technical field [0001] The invention relates to an elastic-plastic polymer alloy sliding bearing material. Background technique [0002] Bearings are used to determine the relative movement position of the rotating shaft and other parts, and play a supporting or guiding role. During the working process of the bearing, its radial direction bears long-term load and high friction, so the bearing is prone to creep, and even fatigue damage or wear failure, resulting in the need for continuous replacement of the bearing. [0003] Ideal non-metallic bearing materials have very high requirements on the tribological properties of materials such as wear resistance, self-lubrication, and limit PV value. At present, many bearing materials have serious wear on the friction pair, the limit PV value is low, the self-lubricating effect is not good, and it is difficult to achieve dry start. Traditional non-metallic materials need to be lubricated or soaked in lubricating medium in advance,...
