Embodiment 1

[0025] Embodiment 1 A kind of thickness is 18mm Juncao fiber board and preparation method thereof

[0026] Cutting: Cut the 1.5-year-old Oasis No. 1 Juncao with a water content of 50.2% to a length of 2-3 cm;

[0027] Cooking: The cut Juncao is steamed and softened under high pressure; the cooking temperature is controlled at 158-160°C, the steam pressure is 5.0-5.5bar, and the cooking time is 2-3min;

[0028] Defiberization and sizing: mechanically disintegrate the cooked Juncao fibers into fibers in a hot mill; add adhesives during the process of ejecting fibers from the hot mills to obtain sized Juncao fibers; the addition of adhesives The amount is 10% urea-formaldehyde resin of the Juncao mass after cooking;

[0029] Drying: Use a flash dryer to air-dry the sized Juncao fiber at 120-160°C, and the moisture content of the dried Juncao fiber is 8.05%;

[0030] Paving, leveling and pre-pressing: pave, level and pre-press the dried Juncao fiber to obtain a Juncao fiber slab...

Embodiment 2

[0037] Embodiment 2 A kind of thickness is 12mm Juncao fiber board and preparation method thereof

[0038] The difference from Example 1 is that in this example:

[0039] Cutting: Cut the 2-year-old Oasis No. 1 Juncao with a water content of 59.5% to a length of 2-3 cm;

[0040] Cooking: The cut Juncao is steamed and softened under high pressure; the cooking temperature is 158-160°C, the steam pressure is 5.0-5.5bar, and the cooking time is 2-3min;

[0041] Defiberization and sizing: mechanically disintegrate the cooked Juncao fibers into fibers in a heat refiner; add an adhesive during the process of spraying out fibers from the heat refiner to obtain sized Juncao fibers; The amount added is 14.9% urea-formaldehyde resin based on the mass of Juncao after cooking;

[0042] Drying: Use a flash dryer to air-dry the sized Juncao fiber at 120-160°C, and the moisture content of the dried Juncao fiber is 8.5%;

[0043] Paving, leveling and pre-pressing: paving, leveling and pre-p...

Embodiment 3

[0049] Embodiment 3 A kind of thickness is 15mm Juncao fiber board and preparation method thereof

[0050] The difference from the above two examples is that cutting: cut the 1-year-old Oasis No. 1 Juncao with a water content of 54.5% to a length of 2-3 cm;

[0051] Cooking: The cut Juncao is steamed and softened under high pressure; the cooking temperature is 158-160°C, the steam pressure is 5.0-5.5bar, and the cooking time is 2-3min;

[0052] Defiberization and sizing: mechanically disintegrate the cooked Juncao fibers into fibers in a heat refiner; add an adhesive during the process of spraying out fibers from the heat refiner to obtain sized Juncao fibers; The amount added is 13.0% urea-formaldehyde resin based on the mass of the cooked Juncao;

[0053] Drying: Use a flash dryer to air-dry the sized Juncao fiber at 120-160°C, and the moisture content of the dried Juncao fiber is 8.35%;

[0054] Paving, sweeping and pre-pressing: Pave, sweep and pre-press the dried Juncao...

Abstract

The invention relates to a preparation method of a fungus grass fiberboard. The preparation method comprises the following steps: cutting: cutting 1-2-year-old fungus grass with the water content of 50-70% into fungus grass with the length of 2-3 cm to obtain cut fungus grass; steaming and boiling: steaming and softening the cut fungus grass under high pressure to obtain steamed and boiled fungus grass; defibrating and sizing: defibrating the steamed fungus grass into fibers in a mechanical mode; adding an adhesive to obtain glued fungus grass fibers; drying: drying the glued fungus grass fibers at the temperature of 120-160 DEG C to obtain dried fungus grass fibers; paving and pre-pressing: performing paving, flattening and pre-pressing to obtain a fungus grass fiberboard blank; and hot pressing: performing hot pressing on the fungus grass fiberboard blank to obtain the fungus grass fiberboard. According to the fungus grass fiberboard, wood chips are replaced by fungus grass which is low in cost and high in growth speed, the preparation process is simple and easy to popularize, and the obtained fiberboard is excellent in various indexes and more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of fiberboards, in particular to a Juncao fiberboard and a preparation method thereof. Background technique [0002] my country is the world's largest wood-based panel production base and exporting country, and the annual demand for wood far exceeds the production volume of wood. As an indispensable means of production and living, wood-based panel products play an important role in the national economy and people's material life. In recent years, with the reduction of forest resources and the improvement of environmental protection awareness, industrial production is bound to save wood resources as much as possible, and the production and use of wood-based panels is one of the main ways to save and efficiently use wood resources. [0003] The main raw material of fiberboard is wood and wood processing residues or other non-woody raw materials, which are processed into fibers and hot-pressed with adhesives a...
