Description

Technical field [0001] The invention relates to the field of materials, in particular to an environmentally-friendly medium-density fiberboard with excellent fireproof performance and a preparation method thereof. Background technique [0002] Wood is a natural composite material with the widest application range and the longest history. It is composed of 50-55% cellulose, 15-25% hemicellulose and 20-30% lignin as main components. Composite materials. According to its structural characteristics, wood can be regarded as an aggregate of oriented fibers in an amorphous substrate, and the unique chemical and organizational structure of wood can be used to modify the wood to achieve the purpose of improving its performance and imparting new functions. Wood composite material is a new type of material with special microstructure and performance composed of wood materials and other materials. Through the use of the composite effect of wood and other materials, the inherent shortcoming...
