Abstract

The invention discloses a metalized wood functional material and a preparation method thereof. The metalized wood functional material is made of four types of materials of tall grass plant stalk, woodcomposite powder, tin-bismuth alloy and natural resin in a compound manner. The preparation method of the metalized wood functional material comprises six steps of plant stalk pretreatment, wood composite powder preparation, plant stalk threading, raw material mat formation, die forming and cutting. The metalized wood functional material prepared by adopting the method is high in strength and good in isotropy, electrical conductivity, heat-conducting performance and anisotropy, can be widely used in the fields such as electromagnetic shielding, system heat management and broad spectrum building materials, and is environmentally friendly.

Description

technical field [0001] The invention belongs to the field of new materials, and particularly relates to a metallized wood functional material and a preparation method thereof. The metallized wood functional material prepared by the invention has high strength and isotropy, good electrical and thermal conductivity and anisotropy, and can be widely used. It is a kind of environmentally friendly metallized wood functional material in the fields of electromagnetic shielding, system thermal management and broad-spectrum building materials. Background technique [0002] Before the appearance of engineering materials such as steel bars, cement, and wood-based panels, the oldest material used by humans was undoubtedly natural wood. In recent years, some researchers have focused their attention on this ancient renewable natural material, trying to make it play a more important role in modern life. [0003] The composite material of wood and metal combines the advantages of wood and ...
