A kind of nano-copper oxide in-situ reduction wood composite material and preparation method thereof

Abstract

The invention discloses a nano-copper oxide in-situ reduction wood composite material and a preparation method thereof. A nano-copper oxide in-situ reduction wood composite material is made of five components, and the components are: Pennisetum micropowder 40%-50%, wheat straw coarse powder 20%-30%, reed fiber 10%~20%, nano-copper oxide powder 10%~15%, polyethylene glycol-400 0.5%~3%. The preparation method comprises eight steps of preparation of Pennisetum micropowder, preparation of wheat straw coarse powder, preparation of reed fiber, batching, preparation of wood alloy powder, material mixing, hot molding and cryogenic treatment. The preparation method comprehensively applies powder metallurgy and powder engineering, composite materials and engineering, wood science and technology and other interdisciplinary material forming theories, and innovates the forming technology and method of wood composite materials.

Description

Technical field[0001]The invention belongs to the field of new materials, and particularly relates to a nano-copper oxide in-situ reduction wood composite material and a preparation method thereof.Background technique[0002]From the adoption of the Framework Convention on Climate Change at the 1st United Nations Conference on Environment and Development in Rio de Janeiro, Brazil in 1992, to the adoption of the Paris Agreement at the 21st Global Climate Conference in Paris, France in 2015, the arrangements for global response to climate change after 2020 were made. By the 2016 G20 summit in Hangzhou, China, China and the United States ratified the "Paris Agreement", while "building an innovative, dynamic, interconnected, and inclusive world economy", it has left endless thinking and heavy burdens for resource, environment and material science and technology workers. On the one hand, mankind’s exploitation and plunder of forests, oil and mineral resources have reached a frantic point; ...

Problems solved by technology

For example, as a typical representative of biomass engineering materials, wood-based panels still have environmental protection problems when used as furniture / building materials. They do not have the beautiful texture and natural color of natural wood, and their weather resistance needs to be improved; when used as mechanical engineering materials, their mechanical properties are low. Insufficient hydrophobic function, poor heat resistance, etc.
