Abstract

The invention belongs to the field of novel material, and relates to an artificial lignumvitae and a preparation method thereof. The invention solves the problems of natural lignumvitae, such as anisotropy of material, scarce resource and expensiveness. The artificial lignumvitae provided by the invention is prepared by uniform mixing and warm compaction on the following components, by mass percentage: 20-80% of a wood-plastic composite powder obtained by mixing, 10-50% of a wood powder, 3-10% of ceramic crystal whisker, 5-20% of an electrolytic copper powder and 0.1-2% of a toner. The product has adjustable color, isotropic material and good self-lubricating, is suitable for water lubrication condition, and can substitute natural lignumvitae for preparation of marine tail bearing, substitute iron / copper base powder metallurgy oil-retaining sliding bearing material for preparation of sliding bearing for electrical equipment in fields of food, medicine and textile, and also substitute rosewood and bovine bone for preparation of high-grade automotive interior.

Description

technical field [0001] The invention belongs to the field of new materials, and relates to a ship stern bearing that can replace natural iron pear wood, replace iron / copper-based powder metallurgy oil-containing sliding bearing materials to prepare sliding bearings for electromechanical equipment in food, medical, textile and other fields, and replace mahogany and bovine bone Artificial iron pear wood for preparing high-grade automobile interior parts and a preparation method thereof. Background technique [0002] At present, the development and plundering of forests, oil and various mineral resources by human beings has reached the point of madness; and the environmental pollution, climate deterioration and inferior Natural disasters have already sounded the alarm for human beings; so people began to consider how to reduce their dependence on forests, oil and various mineral resources. Although the rise of wood-based panels and other industries has played a significant rol...
