Abstract
The invention discloses a wood-based antifriction and vibration-reduction composite material and a preparation method thereof.The preparation method comprises the steps that firstly, a porous wood-based material is cut into blocks to obtain porous wood with the proper size, then the porous wood is immersed in a prepared self-lubricating two-dimensional nano material solution, a self-lubricating two-dimensional nano material enters pores in the wood, the porous wood which fully absorbs the self-lubricating two-dimensional nano material is obtained after drying, the dried porous wood is immersed into a prepared epoxy resin curing agent solution, the porous wood is dried and cured after standing, and the self-lubricating two-dimensional nano material is sealed in the porous structure of the wood through epoxy resin. According to the method, the self-lubricating two-dimensional nano material is poured into the porous structure in the wood, so that the self-lubricating performance of the wood-based composite material is improved, and the friction vibration exciting force suffered by the composite material is reduced; and an epoxy resin curing solution is adopted to strengthen the mechanical property of wood, and finally the wood-based antifriction and vibration-reduction composite material with excellent antifriction and vibration-reduction performance and mechanical property is obtained.
Description
technical field [0001] The invention belongs to the field of materials, and relates to a friction-reducing and vibration-reducing composite material, in particular to a wood-based friction-reducing and vibration-reducing composite material and a preparation method thereof. Background technique [0002] Composite materials are widely used due to their corrosion resistance, excellent mechanical properties, low cost, and easy availability. However, the poor tribological performance of composite materials under harsh conditions is easy to induce vibration and noise due to friction, which limits its application in moving parts of key mechanical equipment, such as ship stern bearings, nuclear reactor inner bearings, large hydraulic machinery bearings and Aeronautical bearings, etc. In order to strengthen the tribological properties and vibration damping properties of composite materials, imitate the porous wood conduit structure, expect to prepare porous composite materials with ...
