Abstract

The invention discloses a bionic microcapsule self-lubrication composite material and a preparation method thereof. The bionic microcapsule self-lubrication composite material comprises a base material and microcapsule structural elements with a lubricating property, and the microcapsule structural elements are uniformly mixed in the base material which is ultrahigh molecular weight polyethylene. The microcapsule structural elements are formed by polymer films and self-lubrication materials enveloped in the polymer films, the microcapsule structural elements are 1-300micron in diameter, and the polymer films are 0.3-50micron in thickness. Since the ultrahigh molecular weight polyethylene serves as the base material, the bionic microcapsule self-lubrication composite material is high in abrasion resistance in application to water lubricated stern bearings; due to a mechanism that guaiac resin which is a core material in the microcapsule structural elements forms emulsion in existence of water, realization of the self-lubrication property of the material is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of composite polymer materials, and specifically designs a bionic microcapsule self-lubricating composite material and a preparation method thereof. Background technique [0002] The stern bearing is an important part of the propulsion system of a ship, and its performance has an important impact on the performance, safety and survivability of the ship. For a long time, key components such as bearings in the propulsion system of weapons and equipment such as ships and underwater vehicles are basically composed of metal components, and mineral oil is used as a lubricating medium. The leakage of lubricating oil can easily cause serious pollution to the environment of rivers, reservoir areas and sea areas. In order to prevent the leakage of lubricating oil, the system must be sealed, so that the component structure is complex and the assembly precision is high. The propulsion system composed of metal component...
