Problems solved by technology

Disadvantages: Sodium hydroxide treatment is easy to degrade wood fibers, break the structure of wood fibers, and affect the mechanical properties of composite materials
Disadvantages: only study the structural state changes of artificial synthetic plastics under supercritical treatment, but fail to study the structural state changes of wood fibers, which are fundamentally different from plastic structures, after supercritical treatment
None of the above studies has solved the problems of sharp decrease in mechanical properties, poor flame retardancy, waterproof and mildew resistance of micro-foamed technology wood under low temperature conditions

Description

【Technical field】 [0001] The invention relates to the field of green and environment-friendly lightweight multifunctional technical wood decoration materials, in particular to a technical wood board based on graphene and non-metallic tailings micro-foaming and a preparation method thereof. 【Background technique】 [0002] my country is a country with a shortage of timber resources in the world. According to data, the per capita timber consumption in my country is 0.22m 3 , the world average is 0.65m 3 , the developed countries have an average of 1.16m 3 , the timber supply gap in 2010 will reach 60 million m 3 . Facing the severe situation and the adjustment of my country's forestry policy, the shortage of timber supply will continue, and it is imperative to find substitute wood resources. Plant fibers such as straw, sugarcane, sawdust, etc. are the most abundant and renewable biomass resources in nature. More representative plant fiber recycling technology solutions inc...
