Reed composite fiber board and manufacture method thereof

Abstract

The invention relates to a reed composite fiber board and a manufacture method thereof. The raw materials include a main material and auxiliary materials. The main material is mixed fiber prepared by reed fiber and fast-growing tree fiber; and the auxiliary materials are adhesive, curing agent and waterproof agent. The main material comprises the reed fiber which accounts for 20-90% of the oven dry weight of the main material, and the fast-growing tree fiber which accounts for 10-80% of the oven dry weight of the main material. In the auxiliary materials, the additive amount of the solid content of the adhesive is 5-15% of the main material, the curing agent is 0-3% of the solid content of the adhesive, and the additive amount of the waterproof agent is 1-4% of the oven dry weight of the main material.

Description

technical field [0001] The invention relates to a reed composite fiberboard manufactured by using artificial fast-growing wood and reed as main raw materials, in particular to a reed composite fiberboard prepared from mixed fibers of reed and poplar and a method for manufacturing the fiberboard. Background technique [0002] Phragmites reed is a perennial herbaceous plant of the Poaceae family. It is a highly differentiated constructive species of wetland vegetation in morphology and is widely distributed in wetlands in various watersheds across the country. my country's existing wetland area is 53.6026 million hectares, of which key reed production areas are Dongting Lake in Hunan, Panjin in Liaoning, and Bosten Lake in Xinjiang. As the main emergent plant in wetlands, reed has remarkable ecological functions, but it must be properly utilized to open up new ways to economically utilize reeds in order to avoid wetland pollution and increase the economic value of wetlands.

Problems solved by technology

[0005] (1) Due to the high toughness of the young shoots of reeds, long strips of wood are usually mixed in the chipping process. These long strips that have not been cut not only wind around the cutter wheel of the drum chipper, but also block the drum and the screen. In addition, the blockage of the pneumatic conveying pipeline, the winding of the fan impeller and the bridging of the wood chip silo resulted in the failure of normal feeding, which seriously affected the production.
