Abstract

The present invention relates to one kind of composite intermediate peashrub board and its making process. The composite intermediate peashrub board is made with intermediate peashrub in 45-90 weight portions, fly ash in 5-35 weight portions, adhesive in 5-20 weight portions, and initiator in the amount of 0.5-3.5 wt% of the adhesive, and through the steps of cutting intermediate peashrub, dedusting, screening, peeling, milling, applying glue, drying, spreading, pre-pressing and hot pressing. The making process is simple and pollution-free, and uses no-formaldehyde adhesive. The produced composite intermediate peashrub board is environment friendly, water-proof, and suitable for in producing furniture, office equipment, floor board, etc.

Description

technical field [0001] The invention relates to a wood-based panel and a preparation method, in particular to a composite wood-based panel produced from caragana and fly ash as main raw materials and a preparation method thereof. Background technique [0002] Caragana is clustered, with strong roots, large plants and crowns, strong germination after sand burial, cold resistance, drought resistance, wind and sand resistance, and strong adaptability. It plays an important role in windbreak, sand fixation, and water and soil conservation. It is widely distributed in Leguminous shrubs in Northeast my country, North China and parts of Northwest China. Caragana is mostly planted in the "Three Norths" area by artificial direct seeding, and the survival rate of the planted forests is extremely high. In the follow-up project of the construction of the "Three North" shelterbelt system, caragana continues to be the main afforestation tree species, with great resource potential. In the...
