Abstract

The invention discloses a cement-based wood fiber artificial board and a manufacturing method thereof. According to the invention, the cement-based wood fiber artificial board is obtained by taking cement as a gel material and taking wood fibers as an organic reinforcing material, doping a certain amount of chemical addition agent, and carrying out steps of batching, agitating, pressurizing, curing, de-molding and maintaining. The artificial board provided by the invention is a novel material with water resistance, anti-oxidation, corrosion resistance and flame retardant property. The wood fiber raw material is selected from leftovers in the production of solid wood furniture and is mixed with cement slurry after being classified, machined and treated, so that the cost of the cement-based wood fiber artificial board is low; and bonding glue is not used so that the pollution to the environment is reduced while timber resources are protected and saved. The cement-based wood fiber artificial board and the manufacturing method thereof, provided by the invention, are applicable to lightweight wall materials for buildings, indoor and outdoor decorative sheet materials, and furniture decorative sheet materials.

Description

technical field [0001] The invention relates to the technical field of organic-inorganic composite materials and resource recycling, in particular to a cement-based wood fiber-based panel and a preparation method thereof. Background technique [0002] Wood, steel, cement, and plastic are the four major raw materials recognized in the world. Although wood is the only renewable biomass material, it is an indisputable fact that the world's forest resources are gradually decreasing. At present, in order to protect forest resources, the domestic logging restriction policy continues to be implemented, and at the same time, various timber-producing countries in the world also frequently introduce strict timber export control policies to protect their own forest resources, resulting in a sharp decrease in the number of timber imports (especially logs). The grim situation will directly affect a large number of downstream industries. Therefore, it is an inevitable trend for future d...
